3D radial probe
Perform formation testing where previously not possible.
In conjunction with DFA, the faster collection of more-representative samples gives you real-time understanding of hydrocarbon properties at reservoir PVT conditions while the MDT tester is still in the borehole. Your formation testing program can be easily modified as real-time data warrants to avoid extended subsequent production testing or lengthy additional PVT laboratory work.
Fitted with the dual-packer module (MRPA), the MDT tester effectively isolates a larger interval of the borehole for conducting a mini-DST or mini-frac testing and fluid sampling.
The MRPA consists of two inflatable high-performance packer elements that effectively seal against the borehole wall to isolate up to an 11-ft interval. The asymmetrical packer design reduces sticking and bulging potential, and operational reliability is further enhanced by the autoretract mechanism (ARM). The ARM applies a longitudinal tensile force to assist in retracting the packers after deflation, in turn minimizing drag.
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 DFA, for even more answers from a single run of the MDT formation tester.
Conduct multiple pressure measurements and collects fluid samples behind the casing in a well.
Limit pressure drawdown during fluid extraction and sampling to optimize well tests and facility design.
Increase the length scale by obtaining permeability and anisotropy away from the wellbore to better understand reservoir heterogeneity.
Recover single-phase samples, representative of downhole formation conditions for accurate compositional and PVT analysis.
