Special Issue Information

Dear Colleagues,

The energy industry is constantly evolving, with drilling engineering at the forefront of this transformation. This Special Issue focuses on the latest advances in advanced drilling engineering, particularly in deep-water, deep-earth, and unconventional oil and gas drilling, and intelligent drilling engineering.

Deep-water drilling has advanced significantly, enabling access to previously untapped resources in the ocean. The successful drilling of wells in ultra-deep waters, such as China’s attempt in the South China Sea, exemplifies the technological capabilities now available. Additionally, deep-earth drilling, as demonstrated by the completion of the 10910-meter-deep Well Shendi-Tak1 in China, has broken new ground in exploring the Earth's interior.

Additionally, more research efforts are being directed towards unconventional oil and gas drilling, crucial for energy diversification, and intelligent drilling engineering, which has the potential to enhance efficiency and safety. We welcome contributions that present novel concepts, research findings, and case studies in these areas.

This Special Issue, “Development of Advanced Drilling Engineering”, seeks high-quality papers on drilling engineering research. Topics of interest include, but are not limited to, the following:

  • Energy industry;
  • Drilling engineering;
  • Advanced drilling;
  • Deep-water drilling;
  • Deep-earth drilling;
  • Unconventional oil and gas drilling;
  • Intelligent drilling engineering;
  • Drill cuttings disposal;
  • Environmentally friendly drilling fluids.

Marine shale is highly prone to wellbore collapse due to its high pore pressure, propensity for hydration and swelling, distinct bedding planes, and low tensile strength. Horizontal in situ stress serves as a critical parameter for wellbore stability analysis; however, its accurate prediction is extremely challenging in complex geological environments. Conventional studies often simplify the wellbore as a circular shape, neglecting its natural elliptical deformation under non-uniform in situ stress, which leads to reduced predictive accuracy. To address this limitation, this study establishes an elliptical wellbore model that incorporates the strain-softening characteristics of shale. Theoretical models for stress distribution in both elastic and plastic zones were derived. The strain-softening behavior was validated through triaxial compression tests, providing a foundation for analytical solutions of stress distributions around circular and elliptical wellbores. Furthermore, an elliptical wellbore-based model was developed to derive a new prediction equation for horizontal in situ stress. Numerical programming was employed to compute stress distributions, and finite element simulations under various aspect ratios corroborated the theoretical results, showing excellent agreement. Results demonstrate that the elliptical wellbore model captures the near-wellbore stress state more accurately. As the aspect ratio increases, the extreme values of radial and tangential stresses increase significantly, with pronounced stress concentrations observed around the 180° and 360° positions. Predictions of horizontal in situ stress based on the proposed model achieved over 89% accuracy when verified against field data, confirming its reliability. This study overcomes the limitations inherent in the traditional circular wellbore assumption, providing a more precise analytical method for wellbore stability assessment in Marine shale under complex geological conditions. The findings offer a valuable theoretical basis for wellbore stability management and drilling engineering design. Full article
