This study introduces a new theoretical and mathematical approach, the Lead Coefficient Theoretical Polynomial Model (EWO), derived from 11 physical and theoretical assumptions. This model formulates the trend equation for cumulative gas production versus production time...

... 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...

We observed that when the coarse model fits within the assumptions of the single-phase pressure diffusivity model, both approaches give close results. We show that when rock compaction is included, the machine learning approach can capture the additional...

Finally, we forecasted remaining inventory, employing a data-driven approach for spacing and development assumptions...

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 result is a workflow for teams to explore an enormous number of realizations of various training data and feature sets in hours instead of months. With these tools, engineers can create accurate forecasts for future wells to better inform...

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...

... 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...

The traditional RTA methods for analyzing multi-stage fractured horizontal wells relies on some major assumptions including: 1) symmetrical planar hydraulic fractures, 2) formation linear flow because of planar fractures, and 3) single phase fluid...
