Abstract
Official abstract text for this publication.
A pump for an oil and gas well includes a barrel with a surface configured to contact oil and gas well fluid. The pump further includes a first coating formed on at least a portion of the barrel surface. The first coating includes a combination of diamond particles and a composition including nickel and phosphorous. The pump also includes a plunger with a surface configured to contact oil and gas well fluid. The pump additionally includes a second coating formed on at least a portion of the plunger surface. The second coating includes a combination of tungsten carbide particles and a composition including cobalt and chromium.
First claim
