...% of the oil in conventional reservoirs. Terry Palisch, director for completions, said it is time to figure how to maximize production with the best combination of well spacing and completion designs in unconventional plays. Ramona Graves, director of academia, is seeing a world of petroleum engineering...

...Stephen Rassenfoss BP is working to push digital rock testing into the mainstream of conventional development. The latest step in its decade-long journey was a deal with Exa, a software firm that partnered with BP to develop a program modeling two-phase flow in conventional reservoirs based on data...

... will swell and its viscosity lowers enough so that it moves through the rock. “It demonstrates that oil can be extracted and that CO 2 can also permeate the rocks,” Sorenson said. This is different from CO 2 flooding in conventional reservoirs in which the goal is to displace the oil and sweep...

.... Unlike conventional reservoirs, whose areal extent is limited and discontinuous (e.g., fluvial channels can appear and disappear), shale plays extend over many square miles. Drilling a well is almost guaranteed to be successful in penetrating a particular shale formation, but this does not mean the well...

... a conventional reservoir. The US Department of Energy’s (DOE’s) Energy Information Administration (EIA) defines the total natural-gas resource base as all of the gas that has ever been trapped inside the Earth, including the volumes that have already been produced. The part of the total natural-gas resource base...

... for conventional reservoirs. Challenges to Development It is important to target zones that show the greatest structural and sedimentary heterogeneity, where higher permeability creates promising pay zones. However, detecting these zones is very difficult because of limited variation in the nature of the rock...

... reservoirs. Tight gas reservoirs exhibit several unique characteristics compared with conventional reservoirs. One of the most significant differences is that conventional reservoirs have a reasonably consistent relationship between porosity and permeability, whereas tight reservoirs may or may not exhibit...

...R.A. Nelson Summary Fractured reservoirs are much more difficult and expensive to evaluate than more conventional reservoirs. In evaluating fractured reservoirs, a particular sequence of study is shown to be effective. This evaluation sequence leads the evaluator to delineate the fracture system...

... reservoir types: conventional reservoirs in coastal deposits are illustrated with an example from the Eagle Sandstone in Tiger Ridge field. Bearpaw Mountains area, north-central Montana (Fig. 1 ); shelf sandstone reservoirs of intermediate quality are exemplified by a coarsening-upward sequence...
