註釋This research is designed to determine if there are any naturally occurring constituents in crude oils that can be chemically altered to bring about increased oil production. An extract containing only the polar organic compounds of the crude oil was obtained by using a modification of the ASTM-2007 procedure. Chemical characterization of the polar compounds were carried out using high pressure liquid chromatography (HPLC) and gas chromatography. The HPLC analyses indicated a range of polar organic compound content of 10 crude oils from 1.6% to 12.7%. Wettability determinations show that by adding a small amount of the polar fraction from a crude oil, to a mineral oil, a 40 to 111% change of wettability toward a more oil-wet system will occur, depending on the specific extract used.
