Water salinity test could boost production from older wells
A new analytical model for brownfield oil reservoirs uses the salinity of injected water to improve the understanding of fluid movements in the operation, said researchers from the Society of Petroleum Engineers. Charting the salinity of production water could help optimise water injection, promoting the most efficient methods and increasing oil recovery, they said. The model was applied to a large oil field in Egypt, where it helped improve understanding of critical issues across about 500 wells, including fluid contacts, well integrity, aquifer support, effect of faults, well zonation, and contribution of commingled wells.
A look at recent first‑quarter results reminds us that there is no such thing as a constant trend in our industry. Continual recalibration of companies’ activities aim to obtain positive financial results in the traditional oil and gas business while devoting efforts in a practical way to both mitigate climate change issues and to develop new forms of energy.
