Integrating Surface and Downhole Measurements for Reservoir Fluid Characterization While Drilling

Maneesh Pisharat, Domain Champion (Europe & Africa), GSS – Surface  Formation Evaluation, Schlumberger

Abstract: New designs in mud gas systems have been instrumental in providing quality data for interpretation purpose. Lighter hydrocarbons accessible to advanced mud gas analysis assist in pay zone delineation and identification of fluid contacts. Many recent published articles provide case studies where results from mud gas analysis have been integrated with other measurements to estimate hydrocarbon density, saturation, permeability, biodegradation, maturity, fractionation, seal efficiency etc. Various factors needed to consider while selecting an appropriate mud gas system for a well and their influence on measured composition together with some applications will be presented.
