Overpressure and petroleum generation and accumulation in the Dongying Depression of the Bohaiwan Basin, China

  title={Overpressure and petroleum generation and accumulation in the Dongying Depression of the Bohaiwan Basin, China},
  author={Xinong Xie and C. Bethke and S. Li and X. Liu and H. Zheng},
The occurrence of abnormally high formation pressures in the Dongying Depression of the Bohaiwan Basin, a prolific oil-producing province in China, is controlled by rapid sedimentation and the distribution of centres of active petroleum generation. Abnormally high pressures, demonstrated by drill stem test (DST) and well log data, occur in the third and fourth members (Es3 and Es4) of the Eocene Shahejie Formation. Pressure gradients in these members commonly fall in the range 0.012‐0.016 MPa m… Expand
