Determination of Unconventional Technical Limit on Shale Wells

Abstract

Abstract The optimization of well drilling is the logical process of analyzing the variables involved in well construction to maximize the efficiency of the operations involved. The philosophy of optimized drilling is based on the knowledge and experience gained in the first drilled well for its learning and application in the drilling of subsequent wells; So that the total cost of drilling is reduced to a minimum. In order to identify those points to be optimized, a methodology of analysis of drilling times (ATP) was developed, which allowed to obtain the actual drilling operations times, non-productive times (NPT's) and normal times for drilling operations. Each of the stages of selected shale / oil gas wells in northern Mexico. Second, we identified the best times, comparable stages and penetration indices (ROP'S) that traversed the selected wells. Finally, the different problems with high frequency indices and best practices were identified to obtain an unconventional technical limit to obtain an optimized baseline for well design and planning.
