... at the point of evaluation. The absolute magnitude of the bias is a direct function of both the variance of the empirical post-peak-production history and the forecasted rates of future production. It is an inverse function of the length of the post-peak-production history. A data set of 54,254 completion...

... was developed. It simulates the development of a core area and takes into account technical and economic parameters. An algorithm calculates the drilling and completion (i.e., fracturing) schedule required to reach and maintain a constrained production plateau determined by the capacity of the export pipe...

...Gürcan Gülen; Svetlana Ikonnikova; John Browning; Katie Smye; Scott W. Tinker Summary The Haynesville shale gas play has significant potential, with an estimated original gas in place larger than that of the Barnett with roughly 63% of the Barnett's acreage. However, the drilling and completion...

Emslie Summary During the last 4 years, more than 330,000 electronic drilling, completion, and intervention documents have been consolidated in a new document-management system, improving both their accessibility and future worth...

... as opposed to being confined to a location's "direct offsets." Exploiting the trend's large amount of well data while taking into account multiple operational and geological parameters could be performed with a statistical system. Final distributions of ultimate recoveries were normalized by completion depth...

... values for an average well from each tier because there will be numerous completions in each tier at the field level. Finally, the model covers 7,885 square-mile blocks in partly drained (4,172 blocks) and undrilled acreage (3,713 blocks); drill-well potential by tier is calculated for the total area...

... have been used to model naturally fractured reservoirs (Kazemi 1969 ; Swaan 1976 ). This model can also be used for modeling shale gas reservoirs where multistage-fracture completions have created the fracture network. In the transient dual-porosity model, there are two transients—one moving through...

The paper includes details of the pilot project, implementation, and the progress and challenges to date...
