Application of geological models gas initially in place estimation, lower Miocene sequence, J gasfield

Abstract

Today, resource management has become a very important task for energy industries in general and oil and gas in particular. Since the oil and gas sector is a sector that needs to be invested economically, the management and evaluation of resource resources need to be given greater attention. Management and planning in the development of oil fields has always been a tough task, and the construction of geological models contributes enormously to the management of oil and gas fields, accompanied by the ability to calculate reserves on the ground through geological modeling, also allows operators to have a better overview of the field. In this paper, based on documentation on geology, geophysics of drilling wells as well as other documents on J field, using methods of collection of documentation, statistics, analysis and evaluation, the paper provides an overview of the process of building a 3D geological model, as well as an assessment of the reserve and exploitation potential of the field through the model. The gas initially in place (GIIP) of the lower Miocene of field J showed that the first layer had 80 million m³, the second layer had 406 million m³ and the third layer had 127 million m³. The result is meaningful in the planning of the future development strategy of the field.
