In Situ Fluid Sampling and Analysis
Downhole Fluid Analysis, Pressure Measurement, and Sampling
Understand your reservoir with one-trip downhole fluid analysis. Downhole fluid analysis begins with pure-fluid extraction, using flowline resistivity and optical measurements to distinguish between formation fluids and water- or oil-base-mud contamination. Test, analyze, and sample even in low-permeability, laminated, fractured, unconsolidated, or heterogeneous formations. Determine real-time fluid gradients, permeability and permeability anisotropy, and contamination levels. Downhole fluid analysis delivers the quantitative measurements you need, at reservoir conditions, in real time.

Petrophysics
Accurately characterizing the reservoir requires petrophysical measurements such as resistivity, neutron, density, sonic, and NMR for quantifying effective porosity, saturations, and permeability. In addition to conventional openhole formation evaluation measurements, we also provide state-of-the-art petrophysical evaluation services in cased wells. This technology opens new avenues for the evaluation of bypassed pay, reservoir monitoring, or reevaluation of brownfields where limited openhole data is available.

The measurement of naturally occurring gamma rays in the formations adjacent to the wellbore is the standard for the correlation of logs in cased and open holes.
Geology
Our borehole imaging services give you microresistivity formation images in both water-base and nonconductive muds. Borehole images are the preferred approach for determining net pay in laminated sediments of fluvial and turbidite depositional environments. Visualizing sedimentary features lets you define important reservoir geometries and petrophysical reservoir parameters, and the interpretation of image-derived sedimentary dip data helps you better understand sedimentary structures. With geological information from the FMI fullbore formation microimager you can stochastically model your sand-shale distribution.
