Completions
This paper presents a study that confirms glass-reinforced-epoxy-lined tubing as a reliable, cost-effective solution for long-term water-injection service in moderate-salinity offshore environments.
This study aims to systematically assess casing integrity and corrosion risks associated with CO2 injection in oil-recovery operations.
This paper presents findings reinforcing the argument that acid fracturing is a strong alternative stimulation method to improve productivity in the Austin Chalk formation.

A new diagnostic technology that exclusively uses surface pressure data to map hydraulic fracturing in unconventional reservoirs has helped an operator to improve well completion designs in its Oklahoma field activities. -
The US EPA’s 2016 New Source Performance Standards updated the 2012 standards by adding requirements for the industry to reduce greenhouse gas emissions, specifically methane. The 2016 NSPS also covers hydraulically fractured oil wells and production, processing, transmission and storage activities.
-
Geophysicists from Stanford University have compiled a map of new maximum horizontal stress orientations in Texas and surrounding areas, potentially giving operators new information for avoiding seismic activity in their hydraulic fracturing operations.
-
The Wyoming Department of Environmental Quality recently concluded that hydraulic fracturing operations were not the likely cause of well water contamination in a small town.
-
Sourcing water for large multifracture stimulations in west Texas is a well-known constraint on oil and gas activities in the area. A 6-month pilot operation demonstrated that produced-water reuse is technically feasible and can be a cost-effective solution.
-
This paper summarizes the benefits of using a bipolymer crosslinking system in environments where water quality cannot be guaranteed. It also demonstrates the yielded cost savings per well that are achievable when reusing 100% produced or flowback water for hydraulic fracturing.
-
Use of a complex-nanofluids (CNF) additive to hydraulic fracturing fluids has doubled even as activity has fallen because of potential production increases.
-
This study compares the performance of openhole-packer completion systems with that of cemented-liner completion systems in the northern Montney gas resource play.
-
Operators continue to look to prolific high-permeability, clastic reservoirs in basins around the world. The use of high-deviation and horizontal well trajectories in these fields improves productivity but increases the challenges of sand control.
-
The engineering and operational planning to ensure that no uncontrolled hydrocarbon releases occur during the execution of subsea big-bore gas wells are described.
