Paper presented at the SPE/IADC Drilling Conference and Exhibition, March 17–19, 2015
Paper Number: SPE-173051-MS
... Abstract Knowledge of swelling properties of shale-oil formations as well as the effects of various drilling fluids, including both water-based and oil-based muds (OBMs), which are of critical importance to wellbore-stability problems, requires a better understanding of shale-oil properties...

... include the following: Mud additives can substantially enhance ROPs in high-pressure conditions and may play a larger role than bit design features. A 16-ppg cesium formate brine increased ROPs 100% as compared to 16-ppg oil-based mud in Carthage marble and Mancos shale. The cesium formate improved...

... a better way to address this problem in the same way it has been successfully demonstrated to work using water-based fluids (WBM). To check the performance of the MFC method while using oil-based mud (OBM), a series of full-scale tests were conducted at Louisiana State University PERTT Laboratory using...

These results have corroborated the laboratory testing which had shown that the fluid stabilizes shales by the same mechanism as does oil-based muds. The drilling fluid, which is based on methylglucoside (MEG), thus has the potential...
