... well's unique properties and operational variables. Once such a robust formulation is in place, then only we will be in a position to answer some of the frequently asked questions such as "Are the PI decline ranges too wide or too narrow? What will happen if we increase drawdown at a well? Will PI...

... windows such as volatile oil, condensate, and heavy oils. The reservoirs represented are the Woodford, and Lower Miss. We picked 26 wells in a similar geological area, with fluid variations as shown in Figure 3 . Abstract One of the continuing puzzle pieces for all unconventional plays is drawdown...

The impact of operating parameters such as drawdown can also be assessed with the tool showing that increased drawdowns may not always be beneficial to the long-term production of the well. The paper presents the underlying drivers for PI Decline for deep-water assets of a specific attribute set...

... the longer production periods depended on the sensitivity of pressure drawdown, liquid rates, wellhead pressure, and fracture geometry parameters. Numerical results showed that the critical parameters affecting the stability of the proppant pack are fracture closure pressure, reservoir pressure, proppant...

... higher than 300 kPa total drawdown; furthermore most of these wells were associated with average liquid rates lower than 150 m3 per day. Given the reservoir properties for these wells, the actual total reservoir drawdown was too high; making it difficult to obtain a history match with reasonable...

This completion used a conventional ESP with Y-tool to create a counteractive pressure drawdown just below the Oil/Water contact in an effort to limit the progression of the water cone. The major limitations with this ESP configuration were casing size (can only be used in 9...
