Mauddud is a major reservoir in Sabiriyah field, North Kuwait. Mauddud belongs to Middle Cretaceous period with about 350 to 400 feet succession dominated by carbonates deposited in ramp environment. Reservoir is characterized by moderate to high porosity and low to moderate permeability. Detailed variations in lithology and formation fluid are generally beyond the resolution of LWD logs, necessitating collaborative approach from different data source to enhance geosteering and in some cases to test independently and validate geosteering interpretations. High quality geochemical data enabled good correlation of offset wells with current drilled wells. The elemental and mineral analysis in this study was key to build effective pre-job model and to highlight signatures; which was utilized while drilling as a reference to pick critical sublayers. The wellsite geochemical technique enabled to build a robust model, independent from conventional LWD modelling techniques, which resulted in near real time reservoir evaluation and aid geosteering through: Characterization of each sublayer based on fluid and rock properties, refinement of landing points, identify different fluid signature and possible charging event, elaborate hydrocarbon quality profile through reservoir section. The technique has high potential for field wide application through effective data integration.
