...-cylinder cement specimens ignore the “ring” shape of the wellbore cement sheath and its nonuniform 3D stress distribution, which may lead to deviations from the actual mechanical properties of the wellbore cement sheath that can affect the theoretical analysis results. In this study, we designed a hollow...

...), as an enhanced oil recovery (EOR) method, has been applied to the Bakken wells. However, fracture interference among wells leads to fast pressure decline during the gas injection period and slow recovery during the production period. By designing strategies that combine water injection in the offset wells...

.... The stable mud weight window recommended was approximately 1.2 to 1.3 s.g, allowing for some minor shear failure. The avoidance of wellbore instability issues led to considerable reduction in time spent addressing drilling-related problems such as reaming, lost circulation, tight spots, etc., thus reducing...

... Abstract Annular pressure buildup (APB) is a major concern in high pressure, high temperature (HP/HT) well design. High temperature hydrocarbon production increases wellbore temperature significantly, inducing a large APB as a result of annular fluid thermal expansion. Vacuum-insulated tubing...

.... And the casing centralizers are used to ensure that the standoff ratio of oil and water layer is above 67%. The displacement with high pump rate (2 m 3 /min, to ensure the annular return velocity more than 1.2 m/s) can efficiently clean the wellbore by diluting the drilling fluid and washing the mud cake...

... reservoirs can be different even if they had the same wormholing pattern around the wellbore. Therefore, acidizing in gas reservoirs should be designed differently from acidizing in oil reservoirs. Sensitivity studies were performed on how a cased and perforated vertical well produced in a high pressure oil...
