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 paper introduces in-pipe inspection technologies enabling high-resolution digital measurements of tubular internal diameter and wall thickness for critical downhole applications.
This case study presents a procedure in which the operator compared production from wells with adjusted wettability to a control group, finding that the adjustments resulted in significant improvements in production and reductions in produced water.
-
The complete paper describes and quantifies the stress-dependence of compaction and permeability for anisotropic rock matrices, natural fractures, and hydraulic fractures, based on comprehensive rock tests of a fractured tight reservoir. -
The complete paper presents a strategy for selecting a surfactant/solvent package for parent wells. Oil recovery and associated water saturation in the microfluidic-based device, with or without surfactant, are quantified and reveal that the oil recovery is enhanced with surfactant.
-
Field examples presented in the complete paper describe principles of data acquisition with a sand-detection tool when run in combination with a production logging string and results of logging in slightly deviated wells completed with sand screens.
-
The complete paper discuses a well with a history of sand production that exhibits long cyclic slugging behavior.
-
Sand-control-installation failures range from minor issues that can be remedied easily to catastrophic events that put the entire well and investment at risk.
-
Schlumberger and a Middle East offshore logistics company signed an agreement to develop a modular stimulation vessel as part of Qatar’s program aimed at localizing the energy sector’s supply chain and creating new investment opportunities.
-
An analysis of existing wells in the Martin Linge field, conducted by Equinor when it took over as operator from Total, revealed that several did not have sufficient barriers, leading the company to plan new wells to ensure safe operation.
-
Unconventional producers around the world have been hamstrung by expensive and cumbersome options when it comes to obtaining reservoir data. Among the latest ways to break past these barriers is a new method developed by Canadian researchers and field tested in Australia’s unconventional frontier.
-
Schlumberger is getting rid of its struggling OneStim business unit 2 years after an acquisition that doubled its size. It will get 37% of the shares of Liberty Oilfield Services, which said it will be the second-largest player in that sector.
-
The Alberta government has announced a new liability management framework aimed at expediting the cleanup of orphan and inactive well sites, signaling a more active approach to reclamation and management of those sites.
