A New Prospective in Geological Data Acquisition for Well Placement Operations

Abstract

Summary The latest technologies and innovations in while drilling technologies relevantly reduce geological uncertainties in Geosteering operations. The Ultra Deep Directional E.M. technology, sensitive to resistivity contrasts up to tens of meters around the drill string, is a significant step change in the oil industry because it represents the missing puzzle piece between borehole data and seismic data. The application of this technology goes beyond traditional real-time well placement with important implications in updating 3D geological models. Multidisciplinary integrated teams of experts from operating and service companies are collaborating more frequently on shared interpretation workflows, improving the effectiveness of data exchange capacity. The final outcome is a geological picture coherent with stratigraphycal, petrophysical and structural real time observations, reducing at the minimum the associated uncertainty and optimizing an efficient drain placing.
