Abstract:
Reducing oil-finding costs by maximum coordination and greater usage of the less expensive exploration methods is discussed. The utility of coordination, and specific gravity and photogeologic applications, are documented with pertinent illustrations.
There are many ways in which surface geology can be useful to geophysics, not only as an aid to structural interpretation, but also in refining the accuracy and improving the efficiency of geophysical methods. The vast majority of geophysical work has been accomplished in relative ignorance of the surface geology. Many specific examples of misinterpretation and waste can be attributed to a lack of consideration of surface geology. Because of this historical lack of surface-geologic consideration, there is a large reservoir of data which can be "high graded" and refined very inexpensively. Photogeology is by far the most rapid, effective, and inexpensive way to do surface geology.

Possibly the geophysical tool most critically affected by the surface geology is gravity. According to Newton's First Inverse Square Law differences in density closest to the gravimeter affect it most critically. Practical ways in which gravity and seismic data can be refined by coordination with photogeology are cited, with slides to demonstrate the problems.
