The US Department of Energy and Pennsylvania Department of Environmental Protection will convert a horizontal Utica Shale gas well into an enhanced geothermal system. Building directly on horizontal drilling and completion practices developed in the Utica, the project will include evaluation of optimal well orientation, lateral placement, and spacing.
An asset swap with PDVSA helps consolidate the supermajor’s heavy-oil operations in the country.
Co-owner Chevron confirmed the find at the Bandit prospect offshore Louisiana and suggested it may become a subsea tieback to existing faciltiies operated by Occidental Petroleum.

The Oklahoma City-based tight-oil producer has agreed to acquire Validus Energy. -
Devon, Shell, and SM Energy offer some of their latest learnings from recent independent subsurface diagnostics projects. Their work underscores why this arena of technology has become a cornerstone for hydraulic-fracture design in tight-rock reservoirs.
-
The paper describes the components of an all-electric system, how it fits within a subsea application, and how it compares with traditional electrohydraulic systems.
-
This paper presents a work flow that has been applied to crossdipole sonic data acquired in a vertical pilot well drilled in the Permian Basin.
-
This paper describes a new intelligent dosing technology to reduce liquid loading in an unconventional tight gas reservoir.
-
The paper provides insights on diffusion in organic matter to correct a primary source of underestimation of gas production in shale-gas models.
-
This paper presents a mathematical analysis of how incorrect estimates of initial reservoir pressure may affect rate-transient analysis in ultralow-permeability reservoirs.
-
As we continue to advance the capability in the laboratory environment to test downhole condition measurements experimentally, the tools we are using appear to be bridging the subsurface characterization with the production results. Continued focus on unconventionals is complemented with a renewed focus on conventional research as well.
-
The key element of hydraulic-fracture modeling is the prediction of the generated fracture geometries. Research conducted over the years has trickled down predictive software. Nevertheless, the ability to design optimal fracture treatments is hampered, as we cannot “see” the subsurface.

In this work, novel physics-based models and machine-learning models are presented and compared for estimating permanent-downhole-gauge measurements.
