... approach addressed the challenges of drilling horizontal wells by using a high-performance aluminum complex and polyamine chemistry to improve wellbore stability. This approach for drilling fluid chemistry provides an alternative replacement for previously used nonaqueous drilling fluids. Three wells were...

... to the fracture plane) for enhanced wellbore stability and fast penetration rates. Fracture treatments were pumped generating mostly longitudinal fractures propagating in the same direction as the maximum horizontal stress (parallel to the wellbore axis) resulting in a poor fracture network and suboptimal...

... associated with several wellbore stability problems. This has caused large amounts of non-productive time to drilling programs and the drilling of sidetracks in some of the wells in this field. A review of the drilling reports and dual-caliper logs from offset wells in the area revealed large amounts...

Although the algorithm touches on several factors affecting extended reach drilling; this paper, which is the first of a two-part series, focuses...

... into consideration. The direct benefit would be that openhole completion greatly reduces the development costs for the 300+ production wells planned for the field. A rock mechanics study was undertaken to provide a comprehensive understanding of wellbore stability of openhole horizontal wells throughout their life...

... Abstract Saudi Aramco has embarked on drilling long horizontals and maximum reservoir contact (MRC) wells in the deep gas reservoirs. Regional stress field is playing an important role in predicting wellbore stability and future production performance of these wells. To successfully drill...
