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.

Semoga and Kaji fields experienced reservoir souring and suffered a history of calcium-carbonate (CaCO3) -scale cases before a proper scale-inhibition program was implemented. Problems with a free water knockout discovered continued scale issues, leading to investigation of the reasons. -
The high level of dissolved iron commonly present in the Marcellus waters of Pennsylvania and West Virginia adversely affects the ability of scale inhibitor to inhibit calcium carbonate scale. This study tests two new products under a range of conditions.

Higher oil prices has created increased interest in chemical enhanced oil recovery (CEOR) using polymers, surfactants, and alkalis. This technology poses some special challenges, especially around water treatment.

Offshore production systems can be impacted negatively by numerous problems attributed to bacterial activity, associated hydrogen sulfide and biogenic iron sulfides, and mercaptan production. Acrolein provides a distinctive all-in-one chemical solution to assist in resolving these problems.
