Real-time downhole fluid characterization is a key factor to an optimized hydrocarbon recovery strategy. Various techniques are available to address downhole fluid properties challenges; however, uncertainty in determination of fluid type and phase behavior from conventional methods can be very high, in addition to other operational risks. It is essential that we develop an integrated approach and workflow that combines different technologies and disciplines. Traditionally, mud gas data has not been part of any of these workflows. Research in mud gas analysis helped to develop advanced tools and processes to address the uncertainties related to measurement. Recently, operators started to integrate real-time data from advanced mud gas logging with downhole fluid analysis such as formation testers.

This talk will focus on advances in mud gas measurements, concepts in analysis and using integrated workflow for fluid characterization with the help of case studies.
