Oilfield chemistry
This paper presents an experiment investigating dissolution of basaltic primary minerals and conditions favorable for secondary phase formation under deep subsurface storage conditions.
This study aims to investigate the efficacy of chemical additives strontium chloride and barium hydroxide in accelerating CO₂ trapping mechanisms, their effect on dissolution of carbonate-bearing minerals, and resulting poroelastic changes in the host rock.
This study reviews subsurface microbial activity, biomineralization reactions, and mechanisms prevalent for bioremediating wells, stabilizing cements, and increasing trapping during CO₂ injection and storage.

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.

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…
