Geoprobe® 3100GT Geotech Rig

Geoprobe® 3100GT Geotech Rig

Over the last 15 years Geoprobe® has increasingly been supporting customers focused on successful geotechnical investigations. On many geotech sites, the need for speed and efficiency is of the utmost importance. The specific methods of geotechnical sampling varies greatly and are usually dependent on a combination of subsurface site conditions and what is considered an acceptable practice in the geographic region.

The Geoprobe® engineering team set out to design a rig specifically for geotechnical sampling that could quickly perform SPT borings (augers & mud rotary), collect shelby tube samples, take rock cores, and push CPT cone…all on a 19,500 GVWR truck that does not require a CDL (Class A/B) to operate. From this vision, the all new Geoprobe® 3100GT was born.

DRILLMAX® DM250 Water Well Rig

DRILLMAX® DM250 Water Well Rig

DRILLMAX® has been a well-known and respected manufacture of geothermal and water well rigs for nearly 34 years, based in Ocala, Florida. The company’s success has been directly tied to their quality of work and the many relationships forged over the years. DRILLMAX® offers the drilling industry a diverse line-up of top head drive drilling rigs.

“For many years DRILLMAX® and Geoprobe® attended many of the same tradeshows.”, shares Tom Omli. “I always looked forward to meeting with Donnie Wood, General Manager of DRILLMAX®, and catching up on the latest news. The more we spoke about the opportunities and challenges our individual companies faced, the more we realized that working together we could help both companies take better care of our respective customer base. In 2017 DRILLMAX® joined Geoprobe®. Bringing companies together is real work, but we are already starting to see new positives emerge.”

One positive example is the NEW DRILLMAX® DM250 which was shown publicly for the first time, April 26th, 2018, at the Geoprobe® Open House in Salina, Kansas. DRILLMAX® has been making DM250 rigs for many years. The DM250 has a proven reputation and is known for being a high production rotary rig that can handle 20 foot drill pipe and still maintain a compact size for mounting on a non-CDL truck chassis. “The combination of torque, mast speed, pumps, and rod loader make drilling 2-in. to 6-in. shallow wells fast and easy on the driller.”, says Donnie. “In addition, the non-CDL chassis makes mobilization to the job sites easier, less costly, and the rig can fit in tight drilling locations.”

The simple goals for the NEW DM250 product was to enhance current operator features, simplify manufacturing, improve serviceability, and reduce rig weight.

Geoprobe® 7822DT Version 3

Geoprobe® 7822DT Version 3

When the engineering team released the first 7822DT product in the spring of 2009 we had a good feeling. We knew there were many features designed into the compact sized track machine. Fast forward 9 years… looking back we had no clue. We didn’t comprehend the impact the 7822DT product would make on the environment and geotechnical industries. The power and versatility of the 7822DT offering allowed Geoprobe® customers to exceed their subsurface sampling expectations and grow their businesses in both direct push and rotary applications. As customers from around the world continue to push 7822DT machines to their limits; tackling difficult site conditions and expand their subsurface scopes of work our customers are asking… How can we do just a little more with our Geoprobe® 7822DT machines? In response the Geoprobe® engineering team is releasing the Geoprobe® 7822DT V3.

Stability:
More than ever, customers are taking 7822DT to sites that include difficult terrains. The proven track undercarriage has been widened 9.5 inches. Increased track width improves stability on sideslopes especially when hauling tools in optional side racks. The track system has also been moved forward 6 inches in relation to the powertrain and drill mast. Why? Over the last few years we’ve seen an increase in customers that are ‘loading the drillmast’ with optional features for rotary applications (ie. 4 speed coring head, dual winches, breakout, etc). These features add weight to the drillmast portion of the rig. By moving the tracks forward users will experience better fore/aft stability making it easier for users to operate on job sites safely.

Enhanced Hydraulic Cooling:
Load sense hydraulics of the V3 machines supply only the system pressure required to perform requested tasks. Under light or no load conditions, system pressure is lowered, significantly reducing heating of the hydraulic fluid. This feature is especially helpful when operating in elevated ambient temperatures and performing high duty cycle operations such as coring, augering, or tracking long distances.

Decreased Fuel Consumption:
The V3 operational controls allow the hydraulic system load on the engine to vary depending on the need of the requested task. For many operations, engine load is reduced and therefore less fuel is consumed as compared to systems that maintain high operating pressures for every task regardless of need. Similar Unit Size and Weight: Strategic engineering design and testing resulted in the 7822DT V3 machine that delivers increased stability, enhanced hydraulic system cooling, and decreased fuel consumption in a package of similar size and weight as previous V2 machines. As commonly equipped, V2 and V3 machines are the same width, height, and weight.

The interlocking design self aligns during assembly and is quick to disassemble

The interlocking design self aligns during assembly and is quick to disassemble

Our patented interlocking split spoon sampler is a unique geotechnical innovation from Geoprobe® that is engineered to greatly benefit your field team. It is built to be 2X stronger, last longer, and saves both money and field time over a conventional split spoon. Additionally, it meets ASTM Standard D1586.

The interlocking design provides axial alignment of the tube halves, making for a quicker assembly of the sampler. Each time it goes together it self aligns, creating a perfect fit. With the threads aligned, the cutting shoe and drive head can be threaded to the split spoon. The threads are a multi-lead, which requires fewer turns during assembly and disassembly over conventional split spoons. Less time is spent during assembly and disassembly, which speeds up each test interval.

In additional to time savings, the interlocking split sheath has two times the strength and durability of conventional split spoons. Enhanced material properties and manufacturing result in greater longevity. Design plays an important role as well. Each interlocking point keeps the two tube halves engaged throughout the sampling process. The strength of these connections prevents the sampler from bulging in dense materials. It also keeps the tube halves tightly engaged even when over-filling of the sampler occurs.

Illustration: The example on the left depicts the standard DT37 soil sampling system being advanced to collect a continuous soil sample. The example on the right depicts using the same 3.75 in. casing to collect SPT samples ahead of the driven casing.

Our customers have used the 3.75 in. probe rod and DT37 soil sampling system to collect continuous soil samples and SPT samples for several years.

Now, we’ve made it possible to collect SPT data via split spoon sampler and automatic drop hammer within the same 3.75 in. driven casing.

With some small tweaks to the system, operators now have access to two valuable pieces of information – continuous soil samples and SPT samples.

This system is applicable anywhere driven casing can be advanced with a Geoprobe® machine. While ASTM D1586 makes no mention of a driven casing method, our preliminary findings have found it to be a promising method for collecting SPT data.

We will continue to conduct field trials, collect scientific data with this method, and work with our friends at ASTM to better educate engineers, consultants, and drillers on best practices regarding the collection of SPT data.

STEP 1: Push detent pin in with thumb and slide drive head into liner.   STEP 2: The Geoprobe® drive head with spring-loaded detent pin easily snaps into place, securing the drive head to the liner. No need to worry about looking for dropped set screws any longer!

STEP 1: Push detent pin in with thumb and slide drive head into liner. STEP 2: The Geoprobe® drive head with spring-loaded detent pin easily snaps into place, securing the drive head to the liner. No need to worry about looking for dropped set screws any longer!

Geoprobe® has developed an all new drive head for the DT22 Soil Sampling System – making an already efficient system even faster and easier.

A simple push of a detent pin in the side of the drive head followed by an easy slip fit into the liner is all that’s necessary.

The spring-loaded detent pin secures the drive head to the liner, which eliminates the need for a machine vice, set screws, and the “push, wiggle, and wedge” method.

No longer do you have to walk around the rig to the machine vice after every soil sampling interval to replace the used liner with a new liner.

Now, the liner drive head doesn’t even have to leave the center rod tool string, nor does the driller or helper have to walk over to the vice to remove the used liner and install a new one. This can all be done right at the borehole at the front of the rig.

This graphic includes basic components of the OIP-G probe with a 525nm green laser diode light source to induce fluorescence of coal tars, creosote, bunker fuels, and similar heavy hydrocarbons.

The Optical Imaging Profiler (OIP) is a new direct push photo-logging system developed by Geoprobe® that uses a down hole light source and Complementary Metal-Oxide Semiconductor (CMOS) camera to investigate for fluorescent contaminants through a sapphire window on the side of the probe.

Of course, this probe is for use in soils and unconsolidated formations. The OIP probe was initially developed with an ultraviolet (UV/275nanometer) light emitting diode (LED) for the detection of fuel fluorescence. Several common organic contaminants of concern (coal tars, creosote, bunker fuels) yield inconsistent results under UV light but do fluoresce under green wavelength light. Therefore, Geoprobe® has developed an OIP probe with a green wavelength (525nm) light source (OIP-G).

The downhole camera acquires images of fluorescence at 30 frames per second that are displayed onscreen while logging. The images are analyzed for the percent area of fluorescence (%AF) by a 2-stage digital filter in the OIP software, and one image every 0.05ft (~15mm) is saved to the log file. If there is no fluorescence, the images are dark.

The OIP-G probe includes a dipole electrical conductivity (EC) array for the measurement of bulk formation EC. The EC and %AF logs are displayed onscreen along with the images of fluorescence as the probe is advanced at approximately 2cm/sec by a Geoprobe® unit. We recommend a drive cushion (MN 221775 for GH60 hammer) be used between the hammer and drive cap to optimize probe life.

Geoprobe® coordinated with Gary Richards and Jonathan Stephenson at the Kansas Department of Health & Environment (KDHE) and their contractor GSI Engineering of Wichita, KS, to conduct a test of the OIP-G system at the former manufactured gas plant in Wellington, KS.

The site is underlain by clay rich alluvium with silty to sandy interbeds to a depth of about 30 ft. with Permian Age shale as the bedrock. We completed OIP-G logs at 39 locations to depths of up to 33 ft. A log from location KD04 at the Wellington site (shown below) lets you see how a typical OIP-G log looks along with an image showing significant fluorescence. The logs revealed the presence of significant fluorescence at several locations and depths. Sampling was performed at selected locations and targeted depths based on the fluorescence logs. The samples collected with the DT22 soil coring system were submitted for analysis of polynuclear aromatic hydrocarbons (PAH). Lab analyses revealed the presence of elevated PAH concentrations in most samples.

Importantly, sampling revealed that false positive results (up to 40%AF) were detected at a few locations. Bench tests with dilute hydrochloric acid revealed that these false positive results occurred due to the presence of calcareous minerals. The fluorescence of calcite is well documented. Inspection of the targeted core samples quickly verified the presence of coal tars or calcareous sediments or caliche nodules.
Following field work, cross sections with EC and %AF logs helped to define the presence and distribution of coal tars in the subsurface and identify preferential migration pathways. These results indicate that the OIP-G system will be a useful tool for investigation of coal tar contaminated facilities.

Geoprobe® 4.5 in. Heavy Duty (HD) sonic drill rod (front) and traditional sonic drill rod (back).

The Geoprobe® 4.5 in. heavy duty (HD) sonic drill rods are significantly stronger than their traditional counterpart and manufactured at our facility in Salina, KS.


“As we worked with a growing number of clients utilizing the power of the Geoprobe® 8150LS GV5 sonic head to go deeper through more difficult subsurface formations, our engineering team recognized an opportunity,” Engineer Jed Davis said.

The Geoprobe® 4.5 in. HD sonic drill rods are engineered to withstand continuous use in harsh conditions and complement the 8150LS full-size sonic rig with 50K dynamic force, which was designed to continuously sample and set casing in excess of 300 ft. in a wide range of formations.

The Geoprobe® 4.5 in. HD tooling consists of two pieces – the sonic drill rod and the coupler.

“The two-piece design allows you a lot of versatility,” Jed said. “Sometimes you need to pin up or pin down and with this you can piece and part stuff together.”

Its unique design incorporates break out flats into the coupler to minimize wear on the jaw pads when breaking tool joints apart. The two-piece design also saves tooling costs, allowing just the coupler to be replaced if the threads are damaged.
The rounded pin joint speeds up the stabbing of joints together for a faster connection. The tool joint also has a larger cross section, which helps strengthen the drill rod and maximize overall thread life.

Video: Interlocking Split Spoon Overview

Our patented interlocking split spoon sampler is a unique geotechnical innovation from Geoprobe® that is engineered to greatly benefit your field team. It is built to be 2X stronger, last longer, and saves both money and field time over a conventional split spoon. Additionally, it meets ASTM Standard D1586.

The interlocking design provides axial alignment of the tube halves, making for a quicker assembly of the sampler. Each time it goes together it self aligns, creating a perfect fit. With the threads aligned, the cutting shoe and drive head can be threaded to the split spoon. The threads are a multi-lead, which requires fewer turns during assembly and disassembly over conventional split spoons. Less time is spent during assembly and disassembly, which speeds up each test interval.

In additional to time savings, the interlocking split sheath has two times the strength and durability of conventional split spoons. Enhanced material properties and manufacturing result in greater longevity. Design plays an important role as well. Each interlocking point keeps the two tube halves engaged throughout the sampling process. The strength of these connections prevents the sampler from bulging in dense materials. It also keeps the tube halves tightly engaged even when over-filling of the sampler occurs.

Our customers have used the 3.75 in. probe rod and DT37 soil sampling system to collect continuous soil samples and SPT samples for several years.

Now, we’ve made it possible to collect SPT data via split spoon sampler and automatic drop hammer within the same 3.75 in. driven casing.

With some small tweaks to the system, operators now have access to two valuable pieces of information – continuous soil samples and SPT samples.

This system is applicable anywhere driven casing can be advanced with a Geoprobe® machine. While ASTM D1586 makes no mention of a driven casing method, our preliminary findings have found it to be a promising method for collecting SPT data.

We will continue to conduct field trials, collect scientific data with this method, and work with our friends at ASTM to better educate engineers, consultants, and drillers on best practices regarding the collection of SPT data.

DT22 Detent Drive Head

STEP 1: Push detent pin in with thumb and slide drive head into liner.   STEP 2: The Geoprobe® drive head with spring-loaded detent pin easily snaps into place, securing the drive head to the liner. No need to worry about looking for dropped set screws any longer!

Geoprobe® has developed an all new drive head for the DT22 Soil Sampling System – making an already efficient system even faster and easier.

A simple push of a detent pin in the side of the drive head followed by an easy slip fit into the liner is all that’s necessary.

The spring-loaded detent pin secures the drive head to the liner, which eliminates the need for a machine vice, set screws, and the “push, wiggle, and wedge” method.

No longer do you have to walk around the rig to the machine vice after every soil sampling interval to replace the used liner with a new liner.

Now, the liner drive head doesn’t even have to leave the center rod tool string, nor does the driller or helper have to walk over to the vice to remove the used liner and install a new one. This can all be done right at the borehole at the front of the rig.

This graphic includes basic components of the OIP-G probe with a 525nm green laser diode light source to induce fluorescence of coal tars, creosote, bunker fuels, and similar heavy hydrocarbons.

The Optical Imaging Profiler (OIP) is a new direct push photo-logging system developed by Geoprobe® that uses a down hole light source and Complementary Metal-Oxide Semiconductor (CMOS) camera to investigate for fluorescent contaminants through a sapphire window on the side of the probe.

Of course, this probe is for use in soils and unconsolidated formations. The OIP probe was initially developed with an ultraviolet (UV/275nanometer) light emitting diode (LED) for the detection of fuel fluorescence. Several common organic contaminants of concern (coal tars, creosote, bunker fuels) yield inconsistent results under UV light but do fluoresce under green wavelength light. Therefore, Geoprobe® has developed an OIP probe with a green wavelength (525nm) light source (OIP-G).

The downhole camera acquires images of fluorescence at 30 frames per second that are displayed onscreen while logging. The images are analyzed for the percent area of fluorescence (%AF) by a 2-stage digital filter in the OIP software, and one image every 0.05ft (~15mm) is saved to the log file. If there is no fluorescence, the images are dark.

The OIP-G probe includes a dipole electrical conductivity (EC) array for the measurement of bulk formation EC. The EC and %AF logs are displayed onscreen along with the images of fluorescence as the probe is advanced at approximately 2cm/sec by a Geoprobe® unit. We recommend a drive cushion (MN 221775 for GH60 hammer) be used between the hammer and drive cap to optimize probe life.

Geoprobe® coordinated with Gary Richards and Jonathan Stephenson at the Kansas Department of Health & Environment (KDHE) and their contractor GSI Engineering of Wichita, KS, to conduct a test of the OIP-G system at the former manufactured gas plant in Wellington, KS.

The site is underlain by clay rich alluvium with silty to sandy interbeds to a depth of about 30 ft. with Permian Age shale as the bedrock. We completed OIP-G logs at 39 locations to depths of up to 33 ft. A log from location KD04 at the Wellington site (shown below) lets you see how a typical OIP-G log looks along with an image showing significant fluorescence. The logs revealed the presence of significant fluorescence at several locations and depths. Sampling was performed at selected locations and targeted depths based on the fluorescence logs. The samples collected with the DT22 soil coring system were submitted for analysis of polynuclear aromatic hydrocarbons (PAH). Lab analyses revealed the presence of elevated PAH concentrations in most samples.

Importantly, sampling revealed that false positive results (up to 40%AF) were detected at a few locations. Bench tests with dilute hydrochloric acid revealed that these false positive results occurred due to the presence of calcareous minerals. The fluorescence of calcite is well documented. Inspection of the targeted core samples quickly verified the presence of coal tars or calcareous sediments or caliche nodules.
Following field work, cross sections with EC and %AF logs helped to define the presence and distribution of coal tars in the subsurface and identify preferential migration pathways. These results indicate that the OIP-G system will be a useful tool for investigation of coal tar contaminated facilities.

Geoprobe® 4.5 in. Heavy Duty (HD) sonic drill rod (front) and traditional sonic drill rod (back).

The Geoprobe® 4.5 in. heavy duty (HD) sonic drill rods are significantly stronger than their traditional counterpart and manufactured at our facility in Salina, KS.


“As we worked with a growing number of clients utilizing the power of the Geoprobe® 8150LS GV5 sonic head to go deeper through more difficult subsurface formations, our engineering team recognized an opportunity,” Engineer Jed Davis said.

The Geoprobe® 4.5 in. HD sonic drill rods are engineered to withstand continuous use in harsh conditions and complement the 8150LS full-size sonic rig with 50K dynamic force, which was designed to continuously sample and set casing in excess of 300 ft. in a wide range of formations.

The Geoprobe® 4.5 in. HD tooling consists of two pieces – the sonic drill rod and the coupler.

“The two-piece design allows you a lot of versatility,” Jed said. “Sometimes you need to pin up or pin down and with this you can piece and part stuff together.”

Its unique design incorporates break out flats into the coupler to minimize wear on the jaw pads when breaking tool joints apart. The two-piece design also saves tooling costs, allowing just the coupler to be replaced if the threads are damaged.
The rounded pin joint speeds up the stabbing of joints together for a faster connection. The tool joint also has a larger cross section, which helps strengthen the drill rod and maximize overall thread life.
