The most challenging aspect is using hydraulic fracturing (fluid availability and management, fracturing fluid and proppant selection, fracturing design, equipment) as it incurs the highest...

... and subsequent field development, which, for several years, was not thought to be possible. Based on the initial vertical well results, three horizontal wells were designed based upon the improved reservoir understanding. This phase was meant to further advance the understanding of the subsurface and completion...

... Abstract In unconventional reservoirs, the well life cycle includes drilling, completion, flowback, and production. The analysis of the fracturing pressure, flowback, and production data provides an early estimate of the stimulated rock volume (SRV) and reservoir flow capacity. In this paper...

... Abstract The early development of a systematic approach to well completion practices centralized around multistage hydraulic fracturing treatments is often the critical component to sustainable reservoir exploitation and development. Unfortunately, the exploitation of either exploratory...

... Abstract In the current high oil / low gas price North American environment, and considering the new options available for well completions technology in unconventional reservoirs, recent industry activities have turned their focus to the areas of Liquid Rich Shales (LRS) and Light Tight Oil...

... to dictate completion development without using resources available to gather the necessary petrophysical information about a play can often lead to disappointing production results. Misinterpreting well results can potentially lead to incorrect assumptions, which can require years to rectify...

... Objectives of the SHALE-1 operations were: evaluate the Silurian Shale for reservoir qualities; identify optimal technology to maximize productivity of unconventional low permeability shale gas reservoir; identify completion, perforation, stimulation, and testing strategy; acquire data...

..., evaluate the shale gas rock properties, and to determine horizontal shale gas targets using vertical or pilot offset wells. Horizontal wells are then drilled and stimulated to maximize reservoir exposure and enhance inflow production performance (Kook et al. 2010). Abstract Drilling, completing...

..., etc…) enables effective multi-disciplinary workflows to optimize both completions and total field development. Abstract Understanding ranges of reservoir depletion is essential in optimizing field development within tight gas plays. Unfortunately, determining reservoir pressure in low...

... potential can significantly fluctuate if treatments are not optimized. As the focus shifted to tighter reservoirs over the years, the well completions have evolved in the Khuff formation from vertical wells that were stimulated to multilaterals and finally to MSF treatments. The success in MSF...

The reality is that there will be a very limited number of wells drilled and completed in support of any unconventional Exploration programme, and therefore any programme should be designed and considered...

... Abstract For many years, the industry has relied on cemented and perforated liners to complete multistage stimulated oil and gas wells. However, the boom in tight oil and gas plays in North America and elsewhere have seen the emergence of open hole multistage system completions as a competitor...

... Abstract The appraisal of deep tight gas reservoirs can be technically and economically challenging, with success dependent on applying the most efficient completion technology. Inevitably, this includes designing well completions that encompass the deployment of multiple hydraulic fracturing...
