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.

Available in skid, container & trailer mounted models

More about the Geo‑Cooler™
Drill Cool's Geo-Cooler mud cooler in action on a rig

With more than 35 years of dedicated mud cooling experience in the Oil & Gas and Geothermal Drilling Industry, Drill Cool Systems is the only company that can offer the innovation, expertise, engineering, and equipment required on the most critical and difficult high temperature wells.

The first mud cooler was successfully developed and deployed by the founder of Drill Cool Systems for the Geothermal Industry in the late 1970s. The benefits of the mud cooler to the rig and associated equipment quickly spread to the Oil & Gas Industry especially in the early HPHT gas wells in the Gulf of Mexico. The design quickly evolved to the first Geo‑Cooler™ that was purpose built by Drill Cool Systems for the offshore industry. The 20ft Freshwater Geo‑Cooler quickly grew as the industry standard for mud cooling needs throughout the Gulf of Mexico, Southeast Asia, Middle East, Australia and Japan along with other high temperature areas of the world.

The Geo‑Cooler™ has continuously served the international high temperature drilling industry for more than 20 years. The ultra-portability, robustness, and flexibility of these drilling fluid temperature control systems continue to prove a valuable essential component of any onshore or offshore drilling program.

High Temperature Drilling Operations

Well Temperature Control™ vs Conventional Drilling

As wells grow in complexity, the need to characterize the temperature, pressure and energy within the drilling system also increases. Parameters such as hole size, flow rate, drilling fluid type, and geothermal gradient all can have a direct thermal impact on the well being drilled and affect your ability to safely and successfully complete the well.

Drill Cool's Dry Air Geo‑Cooler™

No water? No Problem

Using air as a cooling medium, the Dry Air Geo‑Cooler uses a closed loop of heat transfer fluid to effectively reduce drilling fluid temperatures.

The Dry Air Geo‑Cooler is an economical solution for cooling drilling fluids on land based well sites that have limited access to freshwater. The Dry Air Geo‑Cooler consists of three modules: a mud cooler module, an air cooler module & a filter module. The mud cooler module utilizes a wide gap titanium plate heat exchanger with a built-in backflush system for easy cleaning.
