To Collide or not to Collide: Characterizing Wellbore Proximity

Wednesday, 6 March
Grand Ballroom A

With the increase in wells drilled from a single pad and more infill or re-entry drilling the importance of avoiding a collision is becoming more important. The viability of a development can be dependent on the accuracy and reliability of the proximity estimates. While in other applications, relief wells, abandonment and Geothermal developments the objective can be to intersect and ensure we have hydraulic conductivity between wells.     

This session will have 2 parts, in the first part we consider achieving higher resolution in the wellbore separation through new calculation methods and improved measurements. In the second part we look at new ranging tools for rotary as well as coiled tuning assemblies and how these can improve the separation management when we need to connect adjacent wells.
