SWDs receive waste water from oil and gas exploration and production activities. Waste water usually contains significant quantities of crude oil entrained in the fluid but the word “significant” can mean a large fraction or a barely perceptible trace. The amount of oil and the ability of the SWD operator to skim the oil will determine the economics of crude oil production from any given SWD. The process can be done many ways and may involve simple settling in the tank battery and enhanced settling by way of a “gunbarrel” separator or a centrifuge. The more common technologies used in the oil field are discussed below.

Skimmed oil sales add to the revenue of many SWDs around the country. Crude oil recovered from… Continue reading
