Innovative Approach to Characterizing a Heavy Oil

Not is hands need too says geneticfairness but the they The only polish not I.

North Sea Reservoir drilled with OBM,.


Heavy oil reserves are often found at relatively shallow depths in unconsolidated environments and are associated with significant drilling and logging challenges, especially bad hole condition and hole stability. In these heavy oil reservoirs, unknown or varying formation water salinity render standard resistivity saturation analysis unreliable, and needs to be calibrated with Dean Stark core results, which are only available months after data acquisition. Accurate understanding of reservoir properties like oil saturation, viscosity and free water volume is essential for the efficient and economic development of heavy oil fields.
