... Abstract Differences between mud pressure in a wellbore and pore pressure in high permeability rocks can lead to differential sticking, particularly when drilling deviated wells and encountering mud losses. Several solutions, all challenging, can be used to address this problem, where...

... Abstract Prediction of the formation pore pressure is considered as a significant simulation process during the drilling and production phases of the carbonate reservoir. The deficiency in this prediction allows for the occurrence of many troubles like blowouts, kicks, hole washouts, wellbore...

... Abstract Formation pressure is the main function that affects drilling operation economically and efficiently. Knowing the pore pressure and the parameters that affect it will help to reduce the cost of the drilling process. Many empirical models reported in the literature were used...

... a geomechanical model using offset well data. The in-situ principal stresses and their orientations were obtained from wireline logging measurements and mini-frac tests. The repeat formation test (RFT) was used to constrain pore pressure. Rock mechanical properties were calculated using empirical correlations...

... geomechanical model that is used for steering into the most fracable rock. Once the drilling is completed, the frac stage spacing and cluster density is adjusted according to CMSE outputs which include pore pressure, stresses, and natural fracture index. The new approach was used on multiple shale wells where...

... Abstract The pressure regime modeling is an integral part of the well planning and formation evaluation process. An adequate prediction of the estimated pore pressure and better understanding for the pressure regime of any area are important prior drilling any well to optimize the proposed...

... were carried out to compare oil recovery and injectivity during CO 2 flooding. Horizontal core flooding experiments under WAG mode was performed at pore pressures of 3,200 psi and 3,800 psi. The experimental results indicate that tertiary oil recovery was influenced significantly by different CO 2...
