Directly measure formation fluid density and viscosity at reservoir conditions

The InSitu Density reservoir fluid density and viscosity sensor directly measures formation fluid density and viscosity in real time, downhole, at reservoir conditions. No calibration for pressure and temperature is required. This accurate, immediate measurement provides numerous advantages over surface measurements, especially for determining pressure gradients in thin beds or carbonate transition zones and identifying fluid contacts.

The quantified variation of fluid density as a function of depth—instead of having to rely on a linear approximation—readily identifies both compositional grading within a fluid column and whether compartmentalization is affecting zonal connectivity.

The viscosity of reservoir fluid is similarly important because it directly governs reservoir deliverability, injection, sweep efficiency, and enhanced oil recovery (EOR) performance.
