Paper presented at the SPE/IADC Middle East Drilling Technology Conference & Exhibition, October 7–9, 2013
Paper Number: SPE-166770-MS
... Abstract An ultrasonic sensor has been developed for MWD (measurement while drilling) and LWD (logging while drilling) applications that perform real time borehole caliper measurements and also wellbore stability monitoring. The caliper determines the oval shape of the borehole with a defined...

... geosteering services to properly place the well within the reservoir. The steerable System enabled smooth and timely drilling of the drain hole. This resulted in a smooth and in-gauge borehole, hence producing a favourable environment for acquiring good quality real-time images for accurate structural dip...

... harsh conditions of drilling while the bottom hole assembly (BHA) rotates. With logging while drilling (LWD) measurements, several methods have been developed over the years to derive borehole calipers or hole shape indicators from LWD logs. In this paper, we will compare the LWD derived calipers with...
