... a child has a single parent well nearby, particularly when a child well lies between a parent and other infills wells (Type II by Esmaili et al., UrTEC 2021). The machine learning model in this paper includes data from 270 child wells landed in multiple benches and 100 simulated cases across three key...

... significantly alter hydraulic fracture trajectories of the infill wells and offset well, leading to inter-well interference and potentially triggering fault slip. Therefore, there is an urgent need to analyze the causes of inter-well interference, focusing on fracture morphology and in-situ stress, as well...

..." wells, called "child wells," have experienced disappointing production performance due to reservoir depletion by the parent wells. These child wells are distinguished from infill wells which do not interact with parent well depletion. This early development activity resulted in a large number...

... Abstract Drilling and completion of long, highly deviated, or horizontal wells have become commonplace in most mature petroleum reservoirs, especially for unconventional plays. Field observations indicate that most infill wells pass through depleted zones where stress changes are induced...

The paper focuses on the workflow and the process of model calibration, matching historical performance of each well and, validation through a set of blind infill wells. Application of a calibrated complex reservoir...

... Abstract Predicting primary and infill well performance accurately is an industry focus with increasing development of unconventional shale plays. Traditionally, physics-based forecasting models require extensive time to generate predictions compared to the time to plan and implement multi...

... Abstract As development has matured in Devon's Eagle Ford asset, the focus has shifted from primary development to late life optimization. The optimization options that are considered include: drilling of infill wells in the Lower Eagle Ford Member; drilling of redevelopment wells in the Upper...

... results showed that child wells exhibit similar or in some cases larger contacted stimulated areas than infill wells with no depletion. However, their productivity is significantly lower due to preferential fracture growth toward the depleted zones around the parent wells, where there is lower reservoir...

... Abstract It is well known that pre-existing fractures and depletion play an integral role in the completion and production of infill wells. However, it is often left to speculation as to where and how these depleted fractures are distributed along the wellbore. To bring additional context...

... This paper describes a novel process that uses standard drilling data obtained during the drilling of an infill well to identify induced hydraulic fractures that were created during the stimulation of a legacy well. Five case studies are presented to illustrate some insights gained through...

... Abstract There are many recent efforts on fracture mitigation to ensure competitive infill wells. While operators are trying to overcome asymmetrical fractures caused by existing primary wells, there is also a continuous effort to evaluate the quality of the fracture surface area for the infill...

A workflow is presented that improves our approach to a shut in radius which is required when offset wells experience intense pressure spikes within a given radius during the stimulation of infill wells. These pressure spikes are caused by connecting the hydraulic fracture networks and at times...

... Abstract Infill wells’ underperformance in the Permian Basin has raised concerns over decreasing overall production, which can negatively impact future reserve estimates and field economics. The underperformance of infill wells is usually due to changing of the stress state of the reservoir...

... Abstract This Permian Basin case study investigates the impact of primary (i.e., "parent") well depletion on infill (i.e., "child") well completions. The operator used electromagnetic frac fluid tracking to monitor the hydraulic fracturing treatments of three infill wells. The project’s primary...
