X-tended Range Micro Imager (XRMI™) Tool


Superior borehole images, even in highly resistive formations

Our X-tended Range Micro Imager (XRMI™) tool is designed to obtain superior quality images specifically in water-based mud environments. With six pads mounted on independent articulated arms, the XRMI tool has a total of 150 microresistivity sensors. These are used to image the borehole with a resolution of 0.2 in.

Highly resistive formation, high-quality borehole images

Improved tool design and electronics have reduced the signal-to-noise ratio to allow for greater dynamic range. The result is
high-resolution borehole images of your reservoir, whether in highly resistive formations
(Rt > 2000 ohm-m) or relatively salty borehole fluids (Rm < 0.1 ohm-m).

The recorded images allow for a range of detailed interpretation.
Fine changes in sediment body direction can be determined through comprehensive bedding analysis, helping with wellbore placement.
Structural analysis of unconformities, fractures, and faults helps improve the reservoir model. Geomechanics can be used throughout to help aid wellbore trajectories and completion decisions soon after logging, as well as refine the reservoir model. Expensive coring programs can be replaced or reduced when using core to calibrate image analysis.

Applications

  • Optimize offset well placement by evaluating
    structural and stratigraphic features

  • Improve net-to-gross estimations in laminated shaly sands and
    carbonates by classifying pay from non-pay around the wellbore, as well as parallel to it

  • Rationalize well stimulation and formation testing decisions by characterizing the secondary porosity (e.g., fractures and vugs)
    in reservoirs

  • Optimize drilling efficiency and deviated well placement by evaluating and orienting borehole breakout and drilling-induced fractures

  • Optimize reservoir management by characterizing rock texture and electrofacies, possibly calibrated by a reduced coring program
