Gilsonite resin is a commercially proven thermoplastic binder for fiberboard products made by the wet/dry process. High purity, naturally occurring Gilsonite resin is a hard, non tacky binder that produces strong, water resistant fiberboard products, often at faster process rates and with special cost reduction features. Gilsonite has outstanding dimensional stability, stiffness, and strength when […]
Gilsonite is a Unique Natural Resin ABSTRACT GILSONITE has been used successfully for many years in sealant and adhesive products. These applications were restricted to products that could utilize the inherent variability of GILSONITE. Now with new production technology and quality control, this unique natural resin can be considered as a substitute for synthetic resins at […]
For many years, Gilsonite had been recognized by the industry as a solution to shale sloughing, hole enlargement, and borehole instability. In the early 1980s, at the request of American Gilsonite Company, owned by Chevron Corporation, the Chevron Drilling Fluids at the Drilling Technology Center, investigated how Gilsonite works under downhole conditions. A review of […]
Bore-Plate Shale Stabilizer was developed by American Gilsonite Company with three main objectives in mind. These are: excellent shale stability, excellent reaction in a water environment (drilling fluid), and easy dispersability. These objectives were achieved and tested under the guidance of Chevron’s Drilling Technology Center using the O-G-S Downhole Simulation Cell (DSC) in Houston, Texas. First, […]
Mud-Filtrate Invasion in Coring: Mud-filtrate invasion during coring operations has been a major factor affecting the validity of in-situ saturations in reservoir rock. Laboratory studies have documented the possible effects of the drilling mud filtrate invasion on the rock wettability. Considerable effort has been devoted to the measurements of relative permeability by the laboratories of […]
