...Arshad Shehzad Ahmad Shahid; Brecht B. T. Wassing; Peter A. Fokker; Francesca Verga Summary A geomechanical and fluid-flow coupled model was developed to simulate natural-fracture-network reactivation during hydraulic-fracturing treatments in shale gas reservoirs. The fractures were modelled using...

...Patrick Kam; Muhammad Nadeem; Alex Novlesky; Anjani Kumar; Ese N. Omatsone Summary We present a systematic approach to integrate geoscience and dynamic reservoir modeling for two multiwell pads in the Horn River basin, Canada. The Horn River shale-gas play is a world-class unconventional gas...

...Leah Miller Guindon This study provides methods that can be simply applied to constrain forecasts and improve accuracy for forecasting a large number of liquid-rich shale wells. Using simulation cases, the authors demonstrate that constant condensate/gas ratios (CGRs) can occur for tight/shale gas...

...Tae Hong Kim; Kun Sang Lee Summary During the past few years, several studies have analyzed the pressure-transient responses of hydraulically fractured horizontal wells in shale-gas reservoirs. However, that research included simplified models that reflected natural and hydraulic fractures -only...

...Ahmad Alkouh; Steven McKetta; Robert A Wattenbarger Summary Primarily, gas-production data are the main tool used to analyze shale-gas reservoirs. Water production is not usually included in the analysis. In this paper, post-fracturing water flowback and long-term water production are added...

...Wei Yu; Kamy Sepehrnoori Summary Shale-gas production has gained worldwide attention over the past several years. Production from shale-gas reservoirs requires horizontal drilling with multiple hydraulic fracturing to obtain the most economical production. However, there are high cost...

...Morteza Nobakht; Raymond Ambrose; Christopher R. Clarkson; Jerry E. Youngblood; Rod Adams Summary Shale gas reservoirs have become a significant source of gas supply in NorthAmerica because of the advancement of drilling and stimulation techniquesenabling commercial development. The most popular...

...Dmitriy Silin; Timothy J. Kneafsey Summary Our studies of the underlying fundamental gas-recovery mechanisms from shale gas are motivated by expectations of the increasing role of shale gas in national energy portfolios worldwide. We use pore-scale analysis of reservoir shale samples to identify...

Since its invention in the 1980s, AFM has been used in material science and medical research, although it has not received the attention that it probably deserves in reservoir engineering. The emergence of unconventional shale-gas...

...Sherry L. Moore; Colin M. Cripps Summary Traditional ideology on the upper temperature limits of life suggest that extreme temperatures such as those observed in the Horn River Basin shale-gas formation (i.e., up to 175°C) should alleviate microbiologically influenced corrosion and souring concerns...

...Yueming Cheng Summary Slickwater fracturing has been increasingly applied to stimulate unconventional shale-gas reservoirs. Comparing with crosslinked fluids, slickwater used as a fracturing fluid has several advantages, including low cost, a higher possibility of creating complex fracture networks...

This method uses the square-root-of-time plot to remove the apparent skin effect from the data. Then, the data (excluding skin) are used for type-curve analysis...

...Ron G. Stefik; Ken Paulson Summary British Columbia (B.C.) has seen near-exponential growth in the areas of the Horn River and Montney unconventional shale-gas plays situated in northeastern B.C. (Fig. 1). The original-gas-in-place volume for the Montney and Horn River basins has not been formally...

...Jean Yves Lavoie; Jean Sebastien Marcil; Peter Dorrins; Jeremie Lavoie; Roberto Aguilera Summary Since the announcement made in April 2008 concerning the shale-gas potential of the southern Québec lowlands, 30 new wells have been drilled in the area. The calcareous and organic-rich Middle...
