.... When compared to about 350 other horizontal wells, mostly completed without these changes, overall results of the new completion strategy have been very encouraging: Higher injection rates and improved pump time to downtime resulted in a 20+% reduction in days required to complete a typical 8-well...

... and to evaluate surface injection responses during the fracture treatments. Ball-activated fracture valves and plug-and-perf completion strategies were tested to determine whether one is superior to the other. Oil-soluble tracers were used to understand the efficiency of these different completion strategies...

... describes the evolution of completion strategy, including: – Lateral length and number of stages – Method of isolation – Completion and fracturing techniques – Proppant type and concentration Through careful investigation and continual improvement, the authors have been able...

... Abstract In order to obtain commercial flow rates from the Chiswick field, a low permeability gas reservoir in the UK Southern Gas Basin, it was apparent that field development needed horizontal wells with multiple, propped hydraulic fractures. While this completion strategy is commonplace...

... of this study is to recommend an optimized completion strategy to minimize these near-wellbore problems, increase stimulation coverage and decrease unplanned completion expenses. In 2005, 19% of the stages in horizontal wells examined encountered near-wellbore difficulties. This field study inspects the major...

... drawdown pressures. A new sanding model was also built to assist in the completion strategy. This model differentiates between layers that have strong sanding tendency and layers that are competent. Finally, sand-free production rate was reached and maintained by evaluating post-fracture performance...

..., in turn, could result in a sizeable permeability anisotropy. A numerical simulation study was conducted to investigate the impact of horizontal permeability an isotropy and completion strategy on hydrocarbon recovery. The results of this sensitivity study show that the optimum completion strategy consists...

... One of the key elements in building a completion strategy is rooted in recognizing an interval’s facies relationship. This is a difficult and challenging task which is often overlooked by the subsurface technical specialist. Correct facie recognition can impact such things as well placement...
