Integrationof dynamic data of pilot waterflood with rock fabricc-implications for the full field waterflood startup in mauddud reservoir,north kuwait

摘要

The Mauddud limestone of Early Cretaceous is multi-billion barrel depletion drive reservoir undergoing re-development with a planned 260,000 BWPD seawater injection. injection-production history and dynamic dat aintegration with a static reservoir description of the two waterflood pilots illustrates much of what can be expected in the larger scale waterflood. Detail cross-sections were build incorporating geological, petrophysical, surveillance and production data to facilitate this understanding. Over the two and half years of Pilot life great variety of data were acquired which includes: extensive open hole ogs including CMR/NMR, FMI and RFT, COnventional and preserved cores, core sedimentological and fractue study, Geochemical (latroscan & Residual Salt Analysis) analysis, Geomechanical & Reservoir stress analysis, interference testing, production and injection porfile logs, time lapse pulse neutron logs, static bottom hole pressures and pressure build up surveys. Synergistic integration and interpretation of multidisciplinary pilot wells data, has given a detail insight of the controls of fluid flow in the reservoir and the understanding was carried forward to the full field development of Mauddud reservoir using 1-9 spot pattern flooding.
