... included the application and combination of several types of technology, was built upon and optimized through the initial 28 vertical wells. To further improve well performance, long horizontal laterals combined with multistage hydraulic fracturing were needed to provide proof of commercial productivity...

... infrastructure, water resources, expertise, and a general understanding of potential sweet spots due to numerous well penetrations. Even with these favorable conditions, an estimated 40% of unconventional wells are uneconomical due to spatial variability in reservoir characteristics, lateral heterogeneity along...

... Three of the Terryville pay zones under current development for horizontal laterals are the packages of stacked cemented sands referred to as the Cotton Valley "Pink," "Upper Red," and "Lower Red." The PISD log performed on the Lewis 22-1 shows the Pink located from 10,130 to 10,280 ft ( Fig. 3...

..., and fracturing of unconventional formation wells in North America are now commonplace and will begin to play a role in the future of natural gas production in the international market. What is not as common is to drill, complete, and frac multiple lateral branches from a single main wellbore. Multilateral wells...

... Abstract A case study is presented which combines and integrates analyses of microseismic data, production logs, hydraulic fracture treatments, and flow-back performance from four horizontal wells in the Haynesville shale, east Texas. The laterals of the wells are approximately 5,000 ft long...

... section to facilitate positioning of the lateral, identifying suitable water base mud system to improve image log quality, planning a high DLS openhole sidetrack just below 10 3/4" casing shoe and introducing a casing string (just above lateral) to address borehole stability concerns. To address...

... and extended laterals help maximize productivity. Curve intervals drilled with higher dogleg severity (DLS) have a reduced vertical-section which maximizes the length of subsequent lateral section in the productive zone. Wells in US shale plays are usually drilled with a DLS of 10 to 14 °/100 ft...
