Industry experts at URTeC assessed more than a decade of unconventional growth while discussing where productivity gains will come from next.
Chevron and Halliburton describe how they built and deployed the fully autonomous closed-loop fracturing system that enables subsurface-driven optimization.
Weatherford CEO Girish K. Saligram said the acquisition will bolster Weatherford’s completions offerings and unconventional reservoir capabilities.

This study in a shale-oil formation quantified the hydraulic fracture propagation process and described the fracture geometry by developing a geomechanical forward model and a Green’s function-based inversion model for low-frequency distributed acoustic sensing data interpretation, substantially enhancing the value of the LF-DAS data in the process. -
This paper’s authors describe the development of a coiled tubing (CT) nitrogen-lift design in which CT and geothermal reservoir simulations were combined to overcome modeling limitations.

SponsoredHigh-resolution optical measurements hold the key to unlocking the performance of hydraulically fractured wells
-
The paper describes a methodology of verifying that coiled tubing strings have not been subject to erosion caused by annular fracturing operations.
-
The authors describe a carbonate reservoir stimulation technique able to deploy acids in the rock far away from the wellbore through mechanically drilled holes with known depths and azimuths.
-
This paper summarizes the design processes, selection criteria, challenges, and lessons learned during design and execution phases for fracturing in a tight, low-permeability carbonate reservoir with thin layers.
-
This paper presents recent results from a rigorous pilot-scale demonstration of natural-gas foam over a range of operating scenarios relevant to surface and bottomhole conditions with a variety of base-fluid mixtures.
-
In previous features, the focus has been on what is new or reimagined. Therefore, I thought that, in selecting papers for this year’s feature, it would be useful to select ones that look at coiled tubing operations performed and that have been evaluated in one way or another.
-
It won’t happen overnight, but a growing number of US shale players are taking important steps to bring more automation and stage-level decision making to the hydraulic fracturing process in tight reservoirs.

Hydrochloric acid continues to be the most effective and low-cost material for carbonate stimulation. Though exotic chemistries such as chelating agents and organic acids have been promoted for being less corrosive at high temperatures, the cost and dissolving capacity limit their use to large-scale implementation. The ability to inhibit the corrosion tendency of hydr…
