..., downhole mud losses, and induced wellbore instability. The objective of this study is to assess the effect of adding a new copolymer to the invert emulsion drilling fluid to prevent the sagging issue. Sag test was conducted under static conditions over a wide range of temperature (200°F to 350°F). Sag...

Paper Number: SPE-192210-MS
... Abstract The wellbore quality can be affected by a multitude of factors that include drilling operations practices, drilling fluids quality, and geomechanical quality. Low quality wellbores lead to many complications that will result in well completion delay of. One factor of success...

Paper presented at the SPE Kingdom of Saudi Arabia Annual Technical Symposium and Exhibition, April 23–26, 2018
Paper Number: SPE-192192-MS
... Abstract Good and optimal rheology is a primary requisite for a drilling fluid to achieve better hole-cleaning and barite sag resistance. Conventional thickeners like organophilic clay that provide rheology to invert emulsion fluids degrade with time and thereby fail to maintain sufficient...

Paper Number: SPE-182738-MS
... 15% NaCl (volume ration) is suggested to added to the sea water drilling fluid system to lower sea water activity to inhibit the hydration and swelling of clay and enhance the density of sea water from 8.6ppg to 10.02ppg to balance the formation stress in shale formation to avoid the tight hole...
