oa Geological Model of Novoportovskoe Field for Geosteering

Novoportovskoye field is one of the most perspective object of the Company, which contains high oil reserves. In 2015 has been started full-scale drilling on main production targets – NP2-3, NP4, NP5, J2-6. On line navigation requires geological model that has good ability of prediction and shouldn’t change in zones situated far from drilling region. Geological modelling performed in Shlumberger Petrel 15.4. Five algorithms were examined. Suggesting algorithm is using Truncated Gaussian Simulation with 3d trends made with Trend Modelling. Suggesting algorithm provides better ability of prediction and makes geological model more sustainable.
