Oilfield chemistry
This article is the second of a two-part series on produced-water management in the Gulf of Mexico and covers four themes: equipment, process configuration, operations, and effluent quality.
Field examples of operators using chemical restimulation to boost production in aging unconventional wells as an alternative to acid treatments.
This work investigates a cost-effective and sustainable alternative to acidification for sheen control.
-
This paper presents different geochemical approaches to assess the origin of produced gases and thermal maturity and evaluate the effect of adsorption on shale gas during production. -
This paper summarizes techniques for production allocation using geochemical methods and describes a best practice for a specialized approach.
-
There is a thin line between success and failure of clay stabilizers as they can either drive performance or cause unwanted formation damage.
-
Paraffin deposition on the meters measuring produced water volumes causes inaccurate readings. New technology solutions enable lasting accuracy in the place of routine maintenance that provides a temporary solution.
-
The authors of this paper discuss a biosurfactant treatment that offers an economical method for remediation of formation damage caused by high-molecular-weight paraffin wax deposition in porous media.

To evaluate performance of a range of blended inhibitors, a trial was run on a North Sea produced water system which was applying monoethanolamine (MEA) phosphonate-type scale inhibitor as well as novel cleaning programs to counter a high carbonate saturation ratio in the heater. The objective was to find an improved scale inhibitor formulation that would outperform M…

SponsoredCase studies prove the benefits of choosing a greener, more efficient, and more powerful displacement system
-
The authors of this paper develop an assay method to determine effective scale-inhibitor concentration.
-
The authors of this paper demonstrate that future produced-water management and scale-mineral control may need to consider the sequential exposure effect of steel, cement, and shale on fluid chemistry and mineral precipitation.
