low cost integrated teamwork and seismic monitoring improved reservoir management of norwegian gas reservoir with Active Water Drive
Europace, 1994Co-Authors: Per Grinde, J P Blanche, D SchnapperAbstract:This paper shows how new techniques, using integrated seismic and reservoir modelling, have shown there is no need to drill two previously proposed additional need to drill two previously proposed additional producers on the Heimdal gas field. Older simulations had shown this to be necessary in order to recover locally trapped gas. The study emphasizes the necessity of close team work to obtain the detailed reservoir description needed for such a study. A multidisciplinary team of geologists, geophysicists and reservoir specialists performed this study to reappraise the Heimdal Field. Using seismic attributes from 3D (mainly 2D amplitude versus offset AVO) a detailed structural and seismic stratigraphic interpretation provided the geometrical basis for the field model. A heterogenetic approach (identifying potential flow barriers) to detailed geology was then applied using regional experience and detailed field data including the production characteristics. The resulting reservoir model also incorporated offset fields on common regional aquifers, to properly monitor and predict the dynamic pressure behavior and aquifer energy in this series of connecting, Paleocene, turbiditic sands. Two repetitive seismic campaigns have been acquired since the pre-production 3D seismic survey. Mapping of the Water encroachment was accomplished using advanced interpretation techniques of 2D AVO and inversion.more » The results have been integrated into the dynamic matching process in the reservoir simulation.« less

gulf of mexico horizontal well improves attic oil recovery in Active Water Drive reservoir
Symposium on improved oil recovery, 1996Co-Authors: E L Marsh, L J Sienkiewicz, M D MuellerAbstract:In the Gulf of Mexico, many reservoirs are relatively small, thin attic oil accumulations with Active aquifer support. Because of small reservoir sizes and high offshore operational costs, many were developed with a limited number of wells. Due to Active aquifers, conventional wells usually result in limited recovery. Horizontal wells, in many cases, are believed to be a better option for improving oil recovery. This paper presents a field case study which describes the use of horizontal wells to improve oil recovery in thin attic oil, strong Water Drive reservoirs. An integration of technology, ranging from reservoir characterization and simulation to drilling and completion techniques, is shown. Pre-well planning demonstrates the use of reservoir simulation, which incorporates geophysical and geological interpretations, to predict well performance and thus help assess economic potential of the well to be drilled. The paper shows the use of a minimum hole size, minimum mud weight, and a solids-free mud system approach to reduce drilling costs and formation damage while providing for adequate well steering and effective completion. Post-well results, including analysis of well performance data after a year of production, are presented. Results after drilling show that horizontal wells not only help accelerate production but also improve oil recovery compared with conventional wells. It is demonstrated that horizontal wells, applied with an integration of technology, are an economically viable option to improve oil recovery for this type of reservoir problem.

field test of Active Water Drive in n28 1 wellblock of gudao oil field
Journal of Xi'an Petroleum Institute, 2000Co-Authors: Mu JiangAbstract:N28 1 wellblock is a typical unconsolidated sandstone pool of high permeability, high saturation pressure and high viscosity. Its recovery percent of reserves had reached to 26.7% through the development of 24 years. And there is little potential of enhancing oil yield by increasing liquid yield or adjusting well pattern. In order to increase its recovery factor, the field test of Active Water Drive was carried out in February, 1998.To December 31th, 1999,the increased oil production had accumulated to 10952t, Water cut had been decreased to 90%, the recovery factor had been increased by 0.89%. The results show that the Active Water Drive is of obvious effect of oil production increasing, and it has good application prospects.
