High-resolution LWD imaging for geological reservoir description

MicroScope HD resistivity and high-definition imaging-while-drilling service provides unmatched logging-while-drilling (LWD) imaging for reservoir description, from structural modeling to sedimentology analysis, to enable detailed fracture characterization and completion optimization in conductive drilling fluids.

With a vertical resolution of 0.4 in, MicroScope HD service enables operators to see fine features of the downhole environment. The high-definition resistivity imaging supports fracture and dip analysis for structural evaluation of reservoir sections and sedimentology evaluation including image-based porosity determination and thin-bed analysis. This service aids geological interpretation in siliciclastics, carbonates, and unconventional shale oil and gas reservoirs.

Fracture characterization for production optimization

Detailed characterization of fractures is possible with LWD, using high-definition images from the MicroScope HD service. Types of fractures and their morphology and geometry, density, and distribution along the logged interval can be identified. High-resolution images from MicroScope HD service successfully identify fractured zones contributing to drilling fluid losses, and completion design is subsequently developed to isolate those fractures zones, as well as to select proper perforation zones away from the fractures.

MicroScope HD Service Provides Answers, Not Just Datasets

The MicroScope HD 675 service provides multi-depth azimuthal laterolog resistivities and high-definition images of the borehole in the 8.5 in hole size to enable

• well placement and geosteering based on images and dip angles
• sedimentology using porosity and texture distribution
• formation evaluation in high-resolution and estimation of reserves
• structural analysis based on dips and fracture orientation
• fracture characterization for completion design optimization.
