Unconventional/complex reservoirs
This year’s selected papers showcase meaningful advances across condensate‑rich tight gas, tight sandstones, and coalbed methane reservoirs, each contributing new tools for improving predictability and field-development efficiency.
This paper presents a novel approach to predict reservoir porosity by conditioning seismic data, calibrating seismic impedance inversion, and tailoring rock-physics analysis.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

Not everybody suffers when US oil producers slash production. Among the beneficiaries could be US gas producers who will benefit because less oil production will mean a lot less gas on the US market. -
If design A yields the same 90-day production at 10% lower cost in a series of wells than design B wells, is design A the better one? Using pressure-based fracture measurements, the separability of variables between two completion designs can be evaluated.

A downhole compressor solution based on advanced magnetic technologies completed its first field trials in an unconventional gas well. It resulted in a 62% increase in gas production and significant increase in liquid production compared to using a rod pump previously in the well

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.
-
This paper discusses a prescriptive analytics framework to optimize completions in the Permian Basin.

A producer in the Marcellus Basin selected Edge Gathering Virtual Pipelines 2 to capture and liquefy gas from its stranded wells in Tioga County. Initial operation is underway and is set to be ongoing until at least 2022.

The shale sector is seeking answers to a complex issue involving casing deformations that block access to long sections of a lateral. As opposed to frac hits, this rising problem is considered to be an intrawell phenomena.
-
The formula for value in a shale play used to be simple, lease acreage in the best quality rock based on Tiers cover large areas. That standard is fading as it has become obvious that the rock is highly variable and the drilling and completion designs are just as important.

The objective of this study is to show how the capacitance-resistance model (CRM) was used on this field and how it validated the use of other independent methods. This paper demonstrates that integration of different sources of data in reservoir management is critical.

Devon exits the asset that served as the company’s cornerstone for almost two decades and is known to the world as the birthplace of the shale revolution.
