Published: 01 October 1999
... contact to create a water barrier to separate the gas cap and oil column. This methodology has application in reservoirs with a low-dip angle, large gas cap, and a low residual gas saturation to water. It is demonstrated that the net present value of the project is improved if there is an immediate market...

... involves simultaneous production from oil column and gas cap. The drive mechanism consists of down-dip peripheral water injection for oil column in conjunction with barrier water injection at or near gas-oil contact that is designed to separate the gas cap from the oil column and thereby facilitate gas...

...-Water Contact (OOWC) was logged in the reservoir, but no Original Gas-Oil Contact (OGOC) was logged by the wells that penetrated the reservoir. Thus, there existed uncertainty in the OGOC from the Highest Known Oil (HKO) to the crest of the reservoir. During the period of the simulation project, two...

... effect on the oil production. The adopted solution consisted in the creation of a water barrier for isolation of the CO2 cap. For this, seven wells closer to the gas-oil contact were chosen for water injection of a total rate of 2400 m[3]/day. The plan considers the interruption of CO2 injection when...

... execution of the field development project. To confirm the presence or absence of either oil or gas and establish a possible gas-oil-contact (GOC), in some cases the drilling of an appraisal wells(s) may be required. This paper describes a method that does not depend on dedicated appraisal wells to reduce...

... affected the responses of density, neutron, and gamma ray logs, thus making it difficult to identify gas-oil contracts (GOC) and oil-water contacts (OWC) with a cursory look at the well logs. A methodology has been adopted to identify the fluid contracts through the study of well logs and various lithology...
