The Geo-Cooler is your
Well Temperature Control solution for
GEOTHERMAL DRILLING

Geothermal energy began in the United States in the early 1800’s. By the late 1920's electrical power was produced by John D. Grant at the Geysers. Fifty years later, during the oil crisis of 1979, Kern Steel Fabrication invented the Geo-Cooler to support the geothermal industry’s efforts to perform closed-loop drilling, which reduced the environmental impact of drilling. Well temperature control was needed to dissipate heat from the drilling fluid, otherwise it would accumulate heat and turn to steam. Throughout the 1980’s, there was rapid development of new geothermal facilities and our Geo-Coolers grew with the industry. In 1982, our Geo-Coolers began operating in Indonesia and have continued to serve these fields ever since. Kern Steel’s well temperature control business became Drill Cool Systems.  Over the years, we have tackled challenging fields, such as Kakkonda Geothermal Field, Salton Sea, and Haynesville.

Geothermal Drilling Support Worldwide

Our Loyal Customers and Longtime Partners

Geothermal Resource Group

Drill Cool has privilege of working with the Geothermal Resource Group across the United States for +20 years. Under the expert engineering and management of GRG, we have completed long term projects at Hudson Ranch, Puna Geothermal Venture, and Utah FORGE.

“GRG uses the mud coolers from Drill Cool on all the geothermal well drilling operations, one or two mud coolers on the job based on the bottom hole temperature expected. The mud coolers help to cool the mud, maintain the mud rheology, protect the mud pump rubbers, the down hole measurement equipment including elastomers, seals and bearing, improve bit life and drilling efficiency. The mud coolers are easy to maintain and run trouble free, are well services by Drill Cool staff.”

Sam Abraham, VP -Operations

Fonroche Geothermie

Drill Cool has supported Fonroche Geothermie's most recent endeavors in drilling geothermal wells in France.

"We, Fonroche Geothermie, are working with Drill Cool Geo-Coolers™ since 2017 on our high temperature deep geothermal operation in France with success and a high level of reliability and cooling efficiency."

Serge Pecantet, Drilling Superintendent

TNG Energy Services

Drill Cool has worked alongside TNG Energy Services since the 1980’s. Along with the Geo-Cooler, they have delivered adept wellhead services to geothermal customers in the United States, Indonesia, and the Philippines.

Welch Energy Services

Welch Energy Services consults on geothermal drilling projects. Throughout of 15 years of service together, we have delivered safe and cost efficient operations to our geothermal customers.

 

Welch Energy Services

"From 49 years’ experience I can honestly say using the Drill Cool system over the past 15 years or so has significantly reduced mud chemical cost by 30% on jobs where they were utilized. Reduced mud cost and the ability to provide a safe work environment on the pits in a geothermal application the Drill Cool units are a must have. Efficient mob and rig up as well as rig down and demob are also a plus to the system. I do not attempt a project without a Geo-Cooler™."

Drill Cool's
FRESHWATER GEO‑COOLER™

THE ORIGINAL MUD COOLER

THE GEO‑COOLER™ IS THE PERFECT SOLUTION FOR LAND BASED DRILLING WITH ACCESS TO FRESH WATER.

The Freshwater Geo‑Cooler™ is the industry standard for mud cooling needs in all HPHT and geothermal drilling areas of the world – both onshore and offshore. This proprietary mud cooler design incorporates the power and efficiency of a closed circuit cooling tower with the robust versatility of a DNV certified offshore ISO container – thus enhancing the mobility and flexibility of the drilling fluid temperature control system. Many of our customers have realized significant savings by sharing their Geo‑Coolers™ across onshore and offshore drilling programs within the same region.

LEAMS Drilling Seperator

LOW EMISSIONS ATMOSPHERIC METERING SYSTEM

THE BEST TECHNOLOGY FOR REMOVING SOLIDS AND LIQUIDS FROM GEOTHERMAL VAPOR THAT IS VENTED TO THE ATMOSPHERE.

Unlike traditional "Blooie Muffler" drilling separators, the LEAMS makes geothermal drilling safer, faster, efficient and environmentally friendly.  This multi-faceted technology can be used for air, mud, mist or foam drilling, and has the added ability to meter steam and brine flow as part of the drilling process.  No other drilling seperator can perform all of these functions, let alone provide any single function as well as LEAMS.

How Can Drill Cool Help Manage Temperature Related Risks?

THERMAL RISK ASSESSMENT

DETERMINE IF YOUR DRILLING CONDITIONS ARE PUTTING YOUR PROJECT AND PERSONNEL AT RISK

With our Thermal Risk Assessment, together we can determine if your drilling conditions are putting your project and personnel at risk. With a Drill Cool solution our engineers will work closely with your drilling team to ensure overall system safety. We are available from well inception through production to ensure all temperature related risks have been properly characterized and mitigated.

Take the Thermal Risk Assessment now

Personnel icon

Protect Personnel

The safety of rig personnel can be at risk due to elevated drilling fluid temperatures. Human skin that comes in contact with drilling fluid or equipment hotter than 65°C (150°F) can result in a serious burn in just a matter of a few seconds.

Maximize efficiency icon

Maximize Efficiency

The integration of a mud cooler into your high temperature drilling operation can typically result in a 3% to 5% reduction in drilling fluid maintenance costs and promote the greater control of equivalent drilling fluid densities (ECD) throughout the system.

Prevent downtime icon

Prevent Downtime

The Drill Cool System can result in a net costs savings over the duration of the high temperature well by substantially increasing the operational life of mud pump expendables and other surface equipment.
