NMR Logging Application for Complicated Reservoir Formation Evaluation of M Oil Field in Middle East

: There are many carbonate oil fields laying-out in and around Middle-East region, which are the hot productive spot with the huge crude oil reserves. However, these reservoirs also face the challenges of complex lithology, diverse pore configuration, and strong formation heterogeneity to affect the field operation performance. Take Iraq oil companies as an example, before joint operations with overseas oil companies from 2010, only the conventional logging technologies were mainly applied on site, but which can not provide enough support for the development of oil field. After 2010, the advanced logging technologies, such as Nuclear Magnetic Resonance (NMR) logging which are superior to conventional logging in some aspects, are introduced in order to support oil fields development effectively, and which actually makes good performance to direct the identification of non-pay zones, hidden effective zones and micro-fracture distributions. Technical analysis is based on M Oil Field in Iraq to share the experiences of NMR logging application from the view of reservoir engineering in the complicated carbonate reservoir.
