The FMI fullbore formation microimager provides real-time microresistivity formation images and dip data in water-based mud (WBM). With 80% borehole coverage in 8-in boreholes and 0.2-in image resolution in the vertical and azimuthal directions, imaging with the FMI microimager is the preferred approach for determining net pay in laminated ...

At formation resistivities exceeding 500 ohm.m, the high-definition image provided by the FMI-HD microimager consistently provides a superior basis for interpretation. The sharp rendering of fractures and vugs—critical for production—makes them readily identifiable.

May 8, 2024 · Formation microresistivity imaging (FMI) is a borehole-logging technique that uses measured electrical properties to produce two-dimensional “images” of the formations intersected by a borehole.

Examples are the Schlumberger Formation MicroScanner (FMS) and Fullbore Formation MicroImager (FMI) with azimuthal resolution of 64 (FMS) vs 192 (FMI), and capable of radial microresistivity measurements (vertical resolution 0 2”, vertical sampling: 0 1”, depth of investigation: 30”;

Measurement sensitivity in combination with approximately 80% circumferential coverage (in an 8-1/2-inch wellbore) makes the Fullbore Formation MicroImager (FMI) useful for identifying subsurface structures and providing direct data on in-situ stress orientations in the formation intersected in the logged interval.

The FMI-HD microimager takes high-definition to a new level. It builds on the field-proven design of the FMI fullbore formation microimager sonde by incorporating completely new electronics to provide a step-improvement in operating range, reliability, and image quality.

Jun 7, 2016 · FMI imaging logging is defined as a method to obtain electrical images of borehole walls from image processing of resistivity of nearby formations in which the resistivity is measured by an assembled electrode array through dense sampling. For the purposes of our study, FMI logging data from Schlumberger were used. 2.1.

The FMI-HD high-definition formation microimager incorporates all-new electronics and parallel signal processing to image in high definition the water-base mud (WBM) environments that cannot be clearly imaged with conventional microresistivity imaging technology.

Aug 1, 2018 · In the following section on image logs, we present the typical borehole imaging techniques produced by Schlumberger's FMS, FMI, FMI-HD, OBMI, Halliburton's XRMI and Baker Hughes's EI, and describe the basic processing workflows for image log data including speed correction, eccentering correction and normalization.

The UltraTRAC tractor efficiently conveyed the FMI microimager over 4,300 ft in only 7 h from rig-up to rig-down. The real-time high-resolution images revealed a wealth of information about the reservoir to support detailed analysis.
