Predicting the quality of middle Miocene reservoir of some undrilled prospects in north Song Hong basin
Abstract
Song Hong basin evolution was related to the extrusion and clockwise rotation of the Indochina block, which were caused by the collision of the Indian and Eurasian Plates. The extrusion along the Red River Fault Zone, accompanied by clockwise rotation of the Indochina block, controlled the Tertiary sedimentation and deformation of the North Song Hong basin. As the deformation varied along the Red River Fault Zone, the strong uplift and erosion in Late Miocene were only recorded in the North Song Hong basin. There will be a great uncertainty if we use the relationship of porosity versus depth of drilled wells in uplifted and eroded prospects to predict that relationship for undrilled prospects of which the uplift and erosion are unknown.
A combination of seismic data and surrounding well data could help minimise the uncertainty in predicting the relationship of porosity versus depth in the undrilled prospects. This approach was presented in this paper and applied to Middle Miocene reservoir of prospects KL and DL in the North Song Hong basin.
