- Proven Safe and Effective for Deepwater Operations
Gilsonite® uintaite is a safe, naturally occurring hydrocarbon resin with unique chemical properties. Added to drilling fluids, it increases performance and reduces cost in deepwater drilling while minimizing risk.
- Benefits
Gilsonite® uintaite has been proven safe and effective in more than 60 years of oilfield performance. With natural bonding and plugging properties and a high softening point, it is a cost-effective, multi-purpose additive.
- Extends thermal life 10% or more
- Prevents lost circulation
- Minimizes differential sticking
- Stabilizes shales
- Performs in WBM and SBM
- Performs in HP/HT environments
- Reduces cost vs. polymers
- Delivers higher performance with no HSE risk
- Gilsonite® is naturally better®
Gilsonite® uintaite is a naturally occurring asphalt-like solid hydrocarbon rock found only in northeastern Utah. Gilsonite® has significant health advantages over synthetic products.
- Non-toxic (unlike coal or fly ash)
- Non-carcinogenic
- Non-mutagenic
- No extreme safety measures are needed to handle Gilsonite®
- Passes Gulf of Mexico EPA discharge requirements for deepwater operations

Gilsonite® eliminates logging tool sticking tendency in OBM
An international oil company successfully drilled multiple HP/HT wells offshore in Asia, but experienced delays and problems during logging operations due to the tendency of logging tools to stick. Well depths ranged from 14,010 ft to 15,960 ft with bottomhole temperatures from 400º F to 432º. Mud densities ranged from 10.4 ppg to 14.4 ppg. The oil company and the drilling fluids provider conducted laboratory testing that confirmed that adding a high softening point Gilsonite® uintaite to the OBM would improve filtration characteristics and filtercake development. This treatment strategy was adopted during the final drilling phase and before logging commenced. Gilsonite® proved to be effective in optimizing drilling fluid performance characteristics, eliminating logging tool sticking tendencies and allowing wireline logging over 90 hours, and reducing costs by eliminating non-productive time during the logging process.
- Gilsonite® Reduces Costs More Than 80%
Gilsonite® uintaite is a fraction of the cost of premium polymers. With its high softening point, it delivers greater cost advantages at higher temperatures.
Gilsonite® improves performance at a fraction of the price of synthetics alone.
- Gilsonite® Uintaite Extends Thermal Life
American Gilsonite Corporation’s mines have yielded variations of uintaite with a range of softening points. Carefully selected varieties of pure Gilsonite® have been combined to perform to customers’ specifications, at temperatures as high as 500°. Adding Gilsonite® extends the thermal life of synthetic-based mud and water-based mud formulations by 10% or more.
