| Abstract: |
native bottomhole samples of very viscous crude oil (bitumen, tar) are obtained by injecting water plus a suitable surfactant mixture down a hollow sucker rod whereby mixing occurs downhole, producing a resultant oil-in-water emulsion, and recovering the crude oil from the emulsion. Contamination of the crude oil sample with light hydrocarbons is avoided. |
