... trained an ensemble tree-based machine learning model to predict a monthly oil, gas, and water production time series. We then generated undrilled well sticks across each basin using recent spacing assumptions by formation and area (e.g., 10 wells per section across Niobrara formation in the Wattenberg...

This study aims to develop reservoir models blending data-driven insights and physics-based constraints, utilizing routine data (rates and pressures) for pressure-aware production forecasting. We propose a novel approach for identifying rate-pressure relationships in unconventional reservoirs...

The method also enables the identification of dominant flow regimes by using terms with the highest contributions instead of the usual line fitting procedure. Traditional methods like RTA tend to be interpretive and not suitable for field...

... closely tied to the business scale and success. One first order driver of financial results is the tradeoff between well density and completions intensity which involves assumptions about producing reservoir volume and completed reservoir volume. The complexity of unconventional reservoirs prevents...

Paper Number: URTEC-3866237-MS
... Abstract A general assumption in unconventional development is that horizontal wells in close vertical proximity tend to interfere with each other, causing the ultimate recovery of each well to be diminished to the extent that their stimulated rock volume (SRV) overlaps. However, recent...
