MDT Forte and MDT Forte-HT Rugged and High-Temperature Modular Formation Dynamics Testers

The extensively qualified MD Forte and MDT Forte-HT rugged and high-temperature modular formation dynamics testers extend the versatility of the industry-workhorse MDT modular formation dynamics tester to high-temperature well conditions. Our reservoir evaluation experts meet with you to design the tester 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 a module with the MDT Forte and MDT Forte-HT testers 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.
