GEO-CHEMICAL PROCEDURE FOR PROSPECTING OIL DEPOSITS ON SEA BOTTOM Russian patent published in 2011 - IPC G01V9/00

Abstract RU 2417387 C2

FIELD: oil and gas production.

SUBSTANCE: sea water is sampled. Collected material is analysed. There is determined concentrations of metals typical for oil deposits, notably vanadium and nickel. A region of oil deposit existence is established on base of observed change in contents of analysed elements in collected material. Also, not less, than 3-fold excess of background contents of the said elements in sea water indicates occurrence of an oil deposit.

EFFECT: increased reliability of oil deposit prospecting on sea shelf.
