Effects of fibers and pipe rotation on horizontal well cleanout with polymeric fluids
Garcia Prada, Sergio Armando (2022)Rock cuttings deposition is a problem commonly faced during drilling, completion, and intervention activities. Using polymer-based fluids is the to-go technique to improve horizontal hole cleaning. However, the rheological ... -
Effects of Pressure and Oil Contamination on Drainage and Bubble Size Distribution of Aqueous Foams
Shah, Karan Dinesh (2022-05-14)Foams exhibit valuable properties such as high viscosity, low density, and good cutting carrying capacity. However, they are thermodynamically unstable due to gravitational drainage, bubble coalescence, and coarsening. As ... -
Experimental Determination Of Oilfield Cement Properties And Their Influence On Well Integrity
Ichim, Adonis-Costin (2017-12)Oilfield cements are a key element in well construction, during the operational phase of a well, and after its abandonment. Hydrocarbon, geothermal, gas storage and carbon sequestration wells make use of oilfield cements ... -
Experimental Evaluation of a Centrifugal Packer-Type Downhole Separator
Sharma, Ashutosh (2019)With the ever-increasing decline in production of oil wells, application of artificial lift techniques is becoming inevitable. Beam pumps and electrical submersible pumps are two of the most common artificial lift methods ... -
Experimental investigation of elastomer performance for underground hydrogen storage wells
