There has been a long-standing and close co-operation
among industry, government and academic scientists in gathering data about oil
and gas in Canada. Early requirements to accurately record all kinds of
information from the hundreds of thousands of wells drilled to date in Canada
have given us an extremely valuable and reliable database that can be used
quickly and cheaply.
The recent introduction of computerized commercial
databases is speeding up the generation of new drilling prospects, the
optimization of producing fields, and the scrutinizing of field operations.
Additional information can also be obtained by studying
the geochemistry of an area. The chemical composition of sedimentary
fluids and gases near the surface may indicate the presence of oil or gas at
deeper levels. Sometimes shallow holes are drilled to obtain samples for
geochemical testing. The effects of these leaking hydrocarbons may also be seen
by the effect on plants in the area.
Based on this information, the explorationist must then
convince managers or investors to provide funds for further work. The next stage
is to develop an image of the underground formations integrating all the
available geological and geophysical information. It may be possible to obtain
the geophysical data from regulatory bodies or purchase information acquired in
previous surveys. If not, the geologist works with a geophysicist and a
contractor to plan a seismic survey. Obtaining a government licence and
arranging access with landowners is next on the agenda.
