Such analyses are usually performed manually through a curve-fitting process by reservoir and production engineers using their best judgement and experience. Subjectivity is often a large...

A key discovery is that wells can have their estimated ultimate recovery (EUR) predicted early in life with surprising accuracy. Introduction There are many challenges...

... are we discussing efficient well delivery, improving completion effectiveness and fracturing designs, and increasing estimated ultimate recovery as changes we should make. These are changes we now must make to boost production, ensure sustainable cash flow, and increase booked reserves during the “next...

... management addresses the almost impossible task of maximizing short-term production while optimizing ultimate recovery. However, to evaluate the different reservoir-drainage mechanisms, one needs good models, and the more advanced the drainage mechanism is, the more crucial the model is. As an illustration...

... high focus in many organizations. The “maximum efficient rate” often is the compromise—a higher short-term, or plateau, rate than this would damage the reservoir irreversibly and a lower ultimate recovery would be the result. The industry has largely succeeded in maximizing short-term production...

... on improving ultimate recoveries in a number of plays. The interesting thing, however, is that these innovations are not being used in the so-called “legacy shale plays” (e.g., Barnett, Fayetteville) despite the fact that they are producing only break-even economics at today’s gas prices. You would expect...

... usefully. Thus, net pay is central to the static-volumetric method of estimating ultimate recovery. Moreover, it facilitates reservoir simulation, because nonreservoir rock does not need to be characterized for inclusion.

... that typically contain several pay zones. Without cost-effective zonal isolation, however, the full potential of advanced drilling and completion technology to increase production, ultimate recovery, and profitability cannot be realized. Efficient, practical zonal isolation is also important in solving fluid...

..., however, the challenge is even more daunting: to produce more complex hydrocarbon resources economically while continuing to increase ultimate recovery. In the past, a well's longevity could be prolonged by plugging it back and recompleting it in a shallower pay zone, continuing until all zones had...

...Stuart L. Scott Boosting ultimate recovery requires us to get more from each well and each reservoir. Clearly, while improving recovery is one of the best places to look for additional reserves, often the relationship between artificial lift and ultimate recovery has been forgotten. However, when...
