Oilfield chemistry
A new licensing deal with ZL Chemicals will make Chevron’s unconventional EOR technology available to other tight-oil producers.
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.
This paper reviews existing literature, the operator’s records, service-company data, and simulation studies to assess the risk of using seawater in carbonate acidizing.
