The method of the present invention employs a subsurface production pump to displace hydrocarbon fluid, including any and all accompanying ground water and / or earthen contaminants, from the subterranean hydrocarbon reservoir depth of an oil well to surface storage and handling facilities via the subsurface production tubing, wellhead and surface flow line. As the subsurface production pump operates, compressed gas, or a mixture of compressed gases of sufficient volume and force is fed into the lower end of the subsurface production tubing in proximity to, or at a point above the subsurface production pump to mix into the hydrocarbon production fluid column. The resultant and considerably reduced density of the subsurface hydrocarbon production fluid column provides a reduction of subsurface production pump loading with all types of subsurface production pumps, and an improvement of sucker rod fall time when sucker rod activated subsurface plunger pumps are employed. Due to the additional cubic volume of the injected compressed gas, the increased hydrocarbon production fluid and gas velocity within the subsurface production tubing and the surface flow line improves hydrocarbon fluid shear from the conduit walls and sucker rod surfaces, and prevents earthen contaminants such as sand, clay, shale, coal or other rock fragments, from precipitating, accumulating and blocking the flow of hydrocarbon production fluid within the subsurface production tubing and the surface flow line.
