High Resolution Images While DrillingTalk to an expert
The AFR™ Azimuthal Focused Resistivity Service delivers high resolution logging-while-drilling (LWD) borehole images for improved reserves estimates and enhanced understanding of the reservoir structure. Omni-directional and azimuthal laterolog-type resistivity measurements provide quantitative resistivity in environments where the ratio of formation resistivity to mud resistivity (Rt/Rm) is high. At-bit resistivity measurements enable precise geo-stopping at desired casing or coring points.
The AFR service is developed for use in electrically conductive muds, and complements propagation-type resistivity services.
The high resolution, detailed images of structural and stratigraphic features allow for accurate determination of dip and fracture orientation. Understanding dip from real-time images helps improve wellbore placement in the reservoir.
In thinly laminated reservoirs, the AFR service delivers the fine vertical resolution necessary to make accurate net-pay calculations, and determine the direction of breakout for wellbore stability and stress analysis reducing drilling risks.
