    Abstract
  • Shale gas drilling in the south of Sichuan Province has been faced with downhole troubles such as back reaming during POOH in long horizontal section, pipe sticking and mud losses etc. This paper summarizes and analyzes the geological nature and pore and fracture distributions of the Longmaxi shale formation. Technical concerns as to the use of oil base muds are illustrated in this paper, such as plugging of micro fissures in shales, mud rheology control, lubricity of mud in horizontal section to prevent pipe sticking, optimization of mud density, control of low density solids, as well as the prevention and control of mud losses. By analyzing some typical cases, technical challenges as to the use of oil base muds in shale gas drilling are detailed. It is pointed that proper mud density, good mud rheology, good cuttings carrying capacity as well as practical engineering measures play important roles in preventing mud losses and in ensuring downhole safety.
