Paper presented at the SPE Annual Technical Conference and Exhibition, October 26–29, 2020
Paper Number: SPE-204269-STU
.... The primary goal of this research was to simplify the calculations needed to predict polymer rheology and to model polymer behavior without the need for lab testing samples. Polymer samples with varying concentrations, salinities, and hardness levels were prepared and polymer viscosity versus shear...

... slugs. The present model takes into account the expansion of the gas bubble length along the pipeline, generated by the negative streamwise pressure gradient between the pipeline’s entrance and exit, resulting in a longitudinal sequence of non-uniform slugs. The model’s algorithm used to calculate the...

... to calculate the water/oil/gas settling interface during shut-in conditions for an undulating trajectory well. In this method, the well is divided into multiple uphill and downhill sections. For each section, it is assumed that the GOR (Gas Oil Ratio) and WOR (Water Oil Ratio) are the same as the...

Paper Number: SPE-201395-MS
... Abstract After long-time water injection, thief zones (TZ) tend to form and reduce the effectiveness of water flooding in mature oil fields. Several profile control techniques have been developed to resolve this problem. The effect of profile control depends on quantitative calculation of pore...
