...) wells in the Wolfcamp formation and investigate the correlation between the Post-Stimulation Area (PSA) and the total production of the wells. The methodology employed begins with the estimation of the depletion radius of parent wells based on the volumetric analysis of the current production...

...) and document the journey from first discovery to field trials. ADD is a process where un-cemented, open hole laterals are drilled contemporaneously between offset "standard" wells, using the ADD wells to "harvest" productivity from offset well hydraulic fractures. A "standard" well or "frac well" refers...

... Abstract Exploitation of unconventional reservoir wells heavily relies on effective multi-stage hydraulic fracturing treatments to achieve economic production. Considering ultra-tight formations, hydraulic fracturing treatments are conducted with various chemical additives added to the base...

... Abstract Objectives/Scope: The objective of this work was to evaluate the impact of bullhead acid injection on production behavior in an existing unconventional well. Distributed acoustic (DAS) and temperature (DTS) data was collected with deployed fiber optics during production...

... Abstract The Midland Basin, now producing over 2 million barrels a day from horizontal wells, has become a cornerstone of Lower 48 oil production. However, per-well productivity declines over the last two years have clouded the basin's outlook, with potential causes including rock quality...

... Abstract Operators and investors of unconventional shale/tight plays in North America are actively addressing concerns over the degradation of well productivity and resource exhaustion. Operators are deploying strategies that combine improving efficiencies of existing assets and/or accessing...

... in unconventional reservoirs have been discussed by numerous authors. Rate Transient Analysis (RTA) is used to identify productivity decline and for production forecasting to assess estimated ultimate recovery (EUR) under different drawdown scenarios. Geomechanical modeling (GM) approaches focus on understanding...

... American unconventional resources, the study introduces a novel approach using the Sweet-spot Quality Index (SSQI) and Shale Production Index (SPI) methodology, alongside an innovative physics-informed machine learning technique. Machine learning models predict the SSQI for ARF based on key parameters...

... Abstract The underperforming production wells in many pilot research are commonly ascribed to two key contributing components: geological variation and completion strategy. Traditional statistical analysis and machine learning approaches have overlooked the integration of frac-hit and its...

... wells many times show a segmented derivative that is displaced upwards after child wells start production. FD-RTA calibration parameters estimated before the child wells are put on production mismatch history afterwards. We use the theory of FD-RTA to propose that variations in the parent well drainage...

... Abstract As unconventional resource plays mature and infill drilling increases, wellbore damage can result from fracture-driven interactions (FDI) between wells and significantly impact the productivity of a well. It is important for operators to understand the impact of FDI and the methods...

... Abstract The study aims to provide actionable insights for operators and stakeholders on how to manage well spacing, sequencing, and landing zone true vertical depth (TVD) to increase the production potential of unconventional oil and gas wells. The objectives are to evaluate the impact...
