Oilfield chemistry
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.
A laboratory research study evaluates several different chemical injection concepts for the removal of elemental mercury from multiphase flow.

Part 4 of this series provides an overview of ongoing research and recent technology improvements within the US taking place in both academia and the service industry. -
This paper sheds light on newer frontiers of tracer applications with unconventional uses to gain flow insights from an oil and gas reservoir.
-
This paper presents a family of machine-learning-based reduced-order models trained on rigorous first-principle thermodynamic simulation results to extract physicochemical properties.
-
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…
