Learnings Applied to Reservoir Simulation of Unconventional Plays
In the complete paper, the authors revisit fundamental concepts of reservoir simulation in unconventional reservoirs and summarize several examples that form part of an archive of lessons learned.
New Modeling and Simulation Techniques Optimize Completion Design and Well Spacing
Proper lateral and vertical well spacing is critical for efficient development of unconventional reservoirs. Much research has focused on lateral well spacing but little on vertical spacing, which is challenging for stacked-bench plays such as the Permian Basin.
Shale Producers Adopt Geochemistry Fingerprinting to Quantify Cross-Well Production
Knowing which horizon crude oil flows from and in what proportions has been a major challenge for shale producers. Increasingly, they are turning to new technology to find the answer.
Report: “Simple” Well Spacing Calculations Are Inaccurate and Costly
Figuring out how far apart to place horizontal wellbores remains one of the biggest challenges facing the future of the shale revolution. One roadblock appears to be the way in which the sector has traditionally measured these distances.
How Close Is Too Close? Well Spacing Decisions Come With Risks
The ideal well spacing is in the eye of the beholder. The decision depends on so many factors that machine learning is now trying to determine the best combination of ingredients.
The Problems With Bigger Fracs in Tighter Spaces
Fracturing reservoirs effectively can be like boxing. Moving in close enough to land a powerful punch often means a fighter has to take some hits. To effectively develop all the productive rock in a lease, new wells are drilled as close as possible to older ones, making frac hits inevitable.
Completion and Well-Spacing Optimization for Horizontal Wells in Pad Development
In organic shales, hydraulic fracturing is important for optimizing the production of horizontal wells. For a standalone lateral, the propped surface should be maximized to increase production. In the case of a pad, well spacing is an additional factor.
Magnetic Referencing and Real-Time Survey Processing Enable Tighter Spacing of Wells
Wellbore position is computed from survey measurements taken by a measurement-while-drilling (MWD) tool in the bottomhole assembly (BHA).
