Title: Petroleum Engineering as an Aid in Exploration Geology

Author(s): C. V. Millikan (2)


Petroleum engineering contributes to geological knowledge by making and interpreting tests in drilling and producing wells. Core analysis, mud analysis, and electric logs indicate the presence of oil and gas, and a preliminary test may be made through the drill stem. Production and bottom-hole pressure tests prove the stability of the reservoir, indicate its extent and, in some cases, correlation between wells. Improved methods of completing and repairing wells have permitted exploitation of smaller and thinner reservoirs. Better testing methods and more economical drilling have extended the range of exploration both in area and in depth. Many of these advancements of petroleum engineering have been made in the past 3 years or less and promise to continue at an accelerate rate. There will be a parallel increase in their importance to the geologist in his solution of subsurface problems.
