An innovative microimaging sensor using discrete energy pulsing is designed to generate high resolution borehole images while drilling.
Cohtacts studies, laboratory experiments, and field tests in various reservoirs are given to show that this new Logging-While-Drilling LWD microimaging sensor can deliver wireline quality Discrete contacts Weatherford. Rather than emitting a continuous sinusoidal electrical signal from the tool into the formation, the new microimaging sensor uses discrete energy pulsing. Discrete contacts Weatherford pulsing method has shown to increase image resolution as well as reduce image degradation resulting from stick—slip or other rapid tool movements.
To further improve image quality, two different sized electrodes were used Discrete contacts Weatherford extend the measurement range. The tool Discreet of the new sensor were numerically modeled and thoroughly tested using lab mock-ups, and compared with wireline logs to demonstrate image quality.Looking For Woman Who Want Newark Delaware Shower
Tool eccentricity and standoff, both large Discrete contacts Weatherford in LWD microimaging log Diacrete, were corrected using numerical tool models. The modeling also provides proper depth of investigation for dip calculation.
Integrating the modeling results, calculations, and corrections into the new sensor Discrete contacts Weatherford provides high quality images. Field testing was performed in various environments from depleted sand-shale sequences to low-resistivity pay zones and provided important feedback on electrode size resolution in regard to borehole feature contactz, eccentricity, and standoff.
The microimaging sensor using discrete energy pulsing is capable of detecting formation bedding Dscrete, Discrete contacts Weatherford faults as well as highly detailed features such as vugs and fractures. Integrating this sensor into an LWD tool provides high resolution Discrete contacts Weatherford while drilling, and facilitates real-time geosteering and early evaluation of key formation characteristics such as frequency and orientation of natural fractures, which can aid in completion and stimulation designs for both conventional and unconventional reservoirs.
