Reservoir Engineering In Modern Oilfields: Vertical* Deviated* Horizontal And Multilateral Well Systems
Wilson C. Chin
2016 / English / PDF
Real-world reservoirs are layered* heterogeneous and anisotropic* exposed to water and gas drives* faults* barriers and fractures. They are produced by systems of vertical* deviated* horizontal and multilateral wells whose locations* sizes* shapes and topologies are dictated "on the fly* at random"by petroleum engineers and drillers at well sites. Wells may be pressure or rate-constrained* with these roles re-assigned during simulation with older laterals shut-in* newer wells drilled and brought on stream* and so on. And all are subject to steady and transient production* each satisfying different physical and mathematical laws* making reservoir simulation an art difficult to master and introducing numerous barriers to entry. All of these important processes can now be simulated in any order using rapid* stable and accurate computational models developed over two decades. And what if it were further possible to sketch complicated geologies and lithologies* plus equally complex systems of general wells* layer-by-layer using Windows Notepad? And with no prior reservoir simulation experience and only passing exposure to reservoir engineering principles? Have the user press "Simulate*" and literally* within minutes* produce complicated field-wide results* production forecasts* and detailed three-dimensional color pressure plots from integrated graphics algorithms? Developed over years of research* this possibility has become reality. The author* an M.I.T. trained scientist who has authored fifteen original research books* over a hundred papers and forty patents* winner of a prestigious British Petroleum Chairman's Innovation Award in reservoir engineering and a record five awards from the United States Department of Energy* has delivered just such a product* making real-time planning at the well-site simple and practical. Workflows developed from experience as a practicing reservoir engineer are incorporated into "intelligent menus" that make in-depth understanding of simulation principles and readings of user manuals unnecessary. This volume describes new technology for down-to-earth problems using numerous examples performed with our state-of-the-art simulator* one that is available separately at affordable cost and requiring only simple Intel Core i5 computers without specialized graphics boards. The new methods are rigorous* validated and well-documented and are now available for broad petroleum industry application.
