Patent number: 12203029Abstract: The problem of lost circulation is pertinent to the oil industry. To prevent fluid loss, a lost circulation material (LCM), or more generally, a plugging material, can be used to effectively plug the fractures in the rock formation. If the fractures are in the production zone, it is also ideal to unplug them when the drilling operation is complete. Therefore, a material engineered to degrade after a desired period would be useful. In examples, a plugging material has been developed by gelling an oil-based fluid using a low molecular weight gelator, dibenzylidene sorbitol (DBS). DBS gels are robust and show plugging behavior. DBS is shown to chemically degrade in presence of an acid. Hence, a self-degrading gel can be synthesized by incorporating an acid into the system. Further, by varying the type and concentration of the acid, the degradation time of the gel can be controlled.Type: GrantFiled: February 23, 2023Date of Patent: January 21, 2025Assignees: University of Maryland, College Park, BP Exploration Operating Company LimitedInventors: Faraz A.
