Studying the Statistical and Petrophysical of the Mishrif Formation in the Nasiriya Oilfield, Southern Iraq

The Mishrif Formation was studied in seven wells that were distributed in the Nasiriya Oil-field, southern Iraq, well logs were obtained for these wells and included: Gamma ray, Neutron, Density and Resistivity log. The Nasiriya Oil field is located at the unstable platform Mesopotamian zon...

description The Mishrif Formation was studied in seven wells that were distributed in the Nasiriya Oil-field, southern Iraq, well logs were obtained for these wells and included: Gamma ray, Neutron, Density and Resistivity log. The Nasiriya Oil field is located at the unstable platform Mesopotamian zone. The Mishrif Formation was divided into two rock units, the upper MA and lower MB, separated by insulating shale rocks based on the gamma ray log. Furthemore, the lower rock unit was also divided into two reservoir units MB1 and MB2. The petrophysical properties of the formation were studied using various logs and through realationships between the logs. The petrophysical study of the water and hydrocarbon saturations showed that the formation contains varying proportions and quantities of water and hydrocarbons that can be produced. The research also included a statistical study and calculation of reservoir heterogeneity using two methods: first using the Dykstra-Parsons Coefficient, where the results showed that is, the Lateral extension of the reservoir units of the study wells are heterogeneous, and second using the Lorenz coefficient, where the results showed that wells heterogeneous distribution, while Ns-9 and Ns-16 wells a homogeneous distribution.
