Sloughing Shales Sloughing shales solution or heaving shales were encountered in ATDM Gilsonite Co. operations in the Hackberry Field, La. during the late 1960’s. . Numerous fishing jobs because of sloughing shales plagued drilling operations, and the costs of reaming tight holes and weighting up the drilling fluids raised drilling costs substantially. One of the most […]
Gilsonite help Torque and Drag Reduction Lubrication Tests performed in the O-G-S Downhole Simulation Cell (DSC) using cores of various age and hardness in a Bore-Plate®- treated mud system indicate that Bore-Plate(a patented blend of specially-treated Gilsonite grades and other additives) can reduce the effects of drilling fluid filtrate invasion. In water based mud systems, filtrate […]
Gilsonite support to prevent lost circulation What is lost circulation? In the drilling of oil Wells, gas Wells, and the like, the process of pumping a drilling fluid through the well hole to and from the bottom is referred to as circulation. The maintenance of circulation of the drilling fluid is essential to successful drilling by the rotary […]
Gilsonite Resin is composed of a wide variety of different types of hydrocarbon molecules. They may be characterized into two major categories, aliphatics and aromatics. Gilsonite contains approximately 45% to 50% of each. Aliphatics are those hydrocarbons which have the carbon atoms bonded to each other in single bonds. Usually, aliphatics are drawn with the […]

A Better Resin for Heatset Gel Varnishes Environmental Resin ER-125 is a hydrocarbon-based resin created by ATDM Gilsonite Company for use in offset inks, particularly heatset inks. ER-125 Resin is soluble in aliphatic mineral distillates and vegetable oils. It creates varnishes with low and stable viscosities and is an almost totally pure aliphatic hydrocarbon with […]
Gilsonite cement additive Since Gilsonite, a solid hydrocarbon, was introduced to the oil industry in August 1957 as a cement additive, several thousands of jobs have been performed using the material. These operations have included primary cementing through lost-circulation zones of surface, intermediate, and production pipe in both single and multiple stages as well as […]
Resin Compatibility Data The compatibility data of gilsonite given below has been derived from solubility parametersª. Resins are considered compatible when they have similar solubility parameters and are measured in the same solvents. Three hydrogen bonding classes were used to classify the solvents. Solubility Parameters for Gilsonite Solubility Parameters for Gilsonite Weak Hydrogen-bonding Solvents (hydrocarbons, […]
Gilsonite Gilsonite (uintaite) [12002-43-6] is a natural hydrocarbon substance of the class known as asphaltites (see Asphalt), occurring as a coal-like solid which is mined much like other minerals and sold essentially in its native state. The only commercially important deposits of Gilsonite in the world are located in the Uinta Basin, in the northeast […]
