Exploitation geophysics is a type of geophysical techniques with its application in exploitation phase of the oil field. By this technique the co-operation between the Key Laboratory of Petroleum Resources Research, Institute of Geology and Geophysics and Liaohe Oilfield has achieved preliminary results. It shows that oilfield exploitation can get good results in this way. So further co -operation between geophysicists and oilfield experts has a good future in exploitation of oilfield. We hope it will bring a new bright future for oilfield exploitation and offer a new techniques guarantee in finding new oil and gas resources for our country.
