MDT Modular Formation Dynamics Tester

The extensive modularity of the MDT modular formation dynamics tester makes it easily configurable to achieve your formation evaluation goals. Our reservoir evaluation experts meet with you to design the module arrangement and specify test procedures from the wide variety of productivity and permeability tests along with fluid extraction and sampling, usually achievable in a single run of the toolstring. We monitor in situ pressure and fluid measurements in real time to ensure that the job objectives are met. Our multidisciplinary interpretation experts then work with you as needed to leverage this powerful data, such as building predictive reservoir fluid models to determine compositional gradation and reservoir connectivity across the field.

The InSitu Fluid Analyzer system can be deployed as an MDT tester module for obtaining a comprehensive set of fluid measurements at reservoir conditions, spanning direct indicators of fluid sample purity to extensive downhole fluid analysis (DFA), for even more answers from a single run of the MDT formation tester.
