Luation of Recovery Performance of Gas-Condensate Reservoir using Limited Compositional Simulator
(2018-03-23)In the past years, several researches have been done on gas-condensate reservoir recovery performance using fully compositional simulators. Fully compositional simulators are more expensive, time consuming and have complex ...
-
Probability of Wellbore Failure and its Prediction Using Machine Learning
(AUST, 2019-06-09)Wellbore instability (WI) is one of the major challenges experienced during drilling operations costing the oil and gas industry over $1 billion yearly. During the drilling, borehole breakout and drilling induced fractures ...
