Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
19 words
Method of prospecting as in claim 1 including sensing in a line survey downwind of the area being prospected.
Claim 2
Dependent Claim
63 words
Method of prospecting as in claim 1, wherein said sensing is done from a fixed point with respect to proposed oil and gas deposits, said tracking is correlated with ambient wind conditions, and including marking of a projected deposit from said fixed point, gaseous phase density flow and diffusion vertically being projected as a function of ambient wind in the flow being tracked.
Claim 3
Dependent Claim
84 words
Method of prospecting as in claim 1, wherein said sensing is done within heavily wooded areas, from a fixed point with respect to proposed oil and gas deposits, said tracking being correlated with ambient above-canopy wind conditions as a means of estimating bulk drift of the below-canopy air mass, and including marking of a projected deposit from said fixed point, gaseous phase effective flow and diffusion vertically being projected as a function of the governing above-canopy wind related to the below-canopy flow being tracked.
Claim 4
Dependent Claim
27 words
Method of prospecting as in claim 4, wherein said sensing is done from at least two fixed points and including marking of a projected deposit by triangulating.
Claim 5
Dependent Claim
82 words
Method of prospecting as in claim 1 wherein said sensing is done within heavily wooded areas by a lIne survey downwind of the area being prospected; said tracking being correlated with ambient above-canopy wind conditions as a means of estimating bulk drift of the below-canopy air mass, and including marking of a projected deposit from said line survey, gaseous phase effective flow and diffusion vertically being projected as a function of the governing above-canopy wind related to the below-canopy flow being tracked.
Claim 6
Dependent Claim
30 words
Method of prospecting as in claim 1, including sampling of dust bearing adsorbed vapor, with said density flow during tracking and analysis of gas phase material adsorbed on said dust.
Claim 7
Dependent Claim
35 words
Method of prospecting as in claim 7, including capping of earth''s structure surface about a projected oil or gas deposit and measuring vapor phase concentration as a function of diffusion vertically through the earth''s structure.
Claim 8
Dependent Claim
21 words
Method of prospecting as in claim 7, including vacuum sampling of said atmosphere during tracking and analysis of gas phase concentrations.
Claim 9
Dependent Claim
28 words
Method of prospecting as in claim 7, including vertically tracking said density flow, while analyzing gas phase concentrations as a function of the magnitude of said density flow.
Claim 10
Dependent Claim
38 words
Method of prospecting for oil and gas deposits as in claim 1, wherein said sensing includes discriminating between density flow of said hydrocarbon vapor phase arising from oil and gas deposits and any ambient flow of gaseous hydrocarbons.
Claim 11
Dependent Claim
19 words
Method of prospecting as in claim 1, wherein said sensing is directed to volatile constituents of said hydrocarbon phase.
Claim 12
Dependent Claim
13 words
Method of prospecting as in claim 1, wherein said sensing includes infra-red absorption.
