... ABSTRACT In recent years, some platform Wells in the Fengnan 4 well area of Xinjiang Oilfield have adopted the zipper fracturing technology in the production process, which causes the change of pore pressure near the wellbore, and then leads to the complex distribution of ground stress around...

... ABSTRACT Accurate and real-time prediction of formation pore pressure is critical to ensure drilling safety. However, the performance of the most traditional formation pore pressure calculation methods are not satisfied in field applications due to their limited accuracy and time-effectiveness...

... realized that they are critical for a variety of applications, ranging from borehole stability to well stimulation and reservoir management issues such as optimal placement of water injectors and oil producers. The reservoir pore pressure is also a significant parameter that can affect the drilling...

.... The Longmaxi reservoir has an abnormally high pore pressure gradient which ranges from 16.7 kPa/m to 21.7 kPa/m. The stress regime of the Luzhou block is primarily strike-slip type, with an overburden pressure gradient of 25.5kPa/m, and a minimum horizontal stress gradient range of 18.8 to 24.5kPa/m. According...
