... are the higher fraction of hydrolyzed ester and the detection limit of ester, hydrolysis reaction during injection and production times, and fluid drift and tracer dispersion during shut-in time. The main objective of this research is to develop an automated algorithm to design the optimal SWCT test including...

... ester, an emulsion with 70 % of ester and 30 % of brine (in volume), named emulsion 70-30, and a second emulsion, prepared with 60 % of ester (emulsion 60-40). Pressures and temperatures ranges were intentionally selected to simulate actual drilling conditions. Two experimental methods were adopted...

Paper Number: SPE-91009-MS
... understanding of gas solubility in synthetic based drilling fluids plays a fundamental role in terms of preventive (kick detection) and corrective (kick circulation out of the hole) well control practices. The present work involves PVT characterization of two organic liquids (n-paraffin and ester) currently...

Paper Number: SPE-77475-MS
... Abstract Severe environmental regulations lead to the use of biodegradable base oils such as heavy esters of fatty acids from natural origin for drilling applications. An appropriate knowledge of the gas solubility within the fluid in the well is essential for preventing risk of gas kick...
