The outcome of the proposed learning model is an automated engineered completion design adapted to various facies along the lateral, resulting in prediction of stage-production performance. A new type of log acquisition that mixes well testing and logging techniques has been developed...

... and a few times more fluid. As a result, the estimated ultimate recovery of non-Operator H wells is about 18% higher than that of Operator H's wells in the Wolfcamp Formation, indicating that Operator H's completion design can be greatly improved. Therefore, our objective in this work is to optimize...

A concept of dynamic clustering was applied to identify correlations of key well performance drivers to TWP model outputs. Transient PI and dynamic IPR results provided valuable insights on how and when...

... Abstract Evaluating the well performance obtained by different completion designs has been typically restricted to the observed production outcome and its associated completion cost. However, given the multiple factors impacting well productivity in shale and tight reservoirs ( S&T...

... Abstract An ongoing challenge in unconventional reservoirs is the significant production degradation (loss of production) realized from child wells drilled adjacent to depleted parent wells. One strategy hypothesized to reduce the realized degradation is to modify the completion design...
