Reservoir
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.

This paper describes how a better understanding of the connection between the well and the reservoir through use of fiber-optic sensors can improve reservoir simulation models, decision-making, and well-performance evaluation. -
This work evaluates and compares the performance of rate normalization and pressure deconvolution for both synthetic and tight-oil examples.
-
The authors describe an approach to achieve reliable estimation of field gas initially in place.
-
In this study, the application of electrical resistance heating on multilateral wells is studied to illustrate the enhanced physical and economic benefits of the method.

Schlumberger announced that ConocoPhillips will use its DELFI platform to move its data to the cloud.
-
The combined company will control almost 1 million acres in the Williston Basin and daily production over 165,000 BOE/D.
-
The authors discuss a production strategy in which high-gas/oil-ratio crude can be injected into the upper oil reservoirs with partial pressure depletion to achieve production enhancement and synergy among reservoirs.
-
The paper provides information to engineers for selecting high-viscosity friction reducers and describes a methodology for evaluating damage potential and proppant transport.
-
The principles behind unconventional wells lead to production profiles very different from conventional wells. High initial-production rates drop to much lower rates in a matter of months or a few years. How many in the US are currently considered low-production-rate wells?
-
The authors describe the benefits of a single-phase retarded inorganic acid system, which they write features the same benefits as emulsified acids while eliminating the drawbacks of the latter.
