Robotics for Horizontal Image Acquisition in Ultra Slim Wells in Saudi Arabia

The cost savings that are possible by sidetracking existing wellbores make the drilling and completion of ultra slim<br>lateral wells very desirable. Obtaining image logs from horizontal wells, less than 6” diameter, has always been a<br>challenge, because the size of conventional borehole imaging tools that currently exist on the market are simply<br>too large. In addition, conventional deployment methods limit efficient rig time utilization and ultimately lead to<br>higher cost. New conveyance and logging technology from Welltec® (the Well Tractor®) and Weatherford (The<br>Compact Micro Imager – CMI) allows operators to obtain excellent image logs in slim wells as small as 3” in<br>diameter. Image logs are required to properly understand fracture details and to help in future drilling and<br>completion decisions.
