Oilfield chemistry
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…
The future of the heavy-oil business in Alaska looks more promising than ever after a 2-year pilot delivers technical and economic success.

Mixing dry polymer powder and water to make friction reducer as needed during fracturing can cut the cost of the additive and the testing of whether a drastically simplified recipe performs as well as more-complex mixes.

Friction reducers play multiple critical roles in fracturing. A challenge in selecting the best one for the job is the growing evidence that performance varies, but objective performance measurements are lacking.

A review of the properties of iron compounds and their impact in shale produced water treatment with an emphasis on their colloidal forms. A wide range of problems is associated with these compounds in produced water including emulsion stabilization, oil-coated solids, pad formation in separators, pipeline solids, and plugging of water disposal formations.

The obsession with better hydraulic fracturing has steadily pushed on shale production in year one, but the decline remains steep. Chemistry could help explain, and perhaps extend, the short productive life of these wells.
