Versa-Drive plug milling service drilled, cleaned out two unique unconventional wells, each in one run, saved $150k USD

Drilling longer horizontal wells has become common among operators for maximizing production from the reservoir. However, tight lease boundaries can limit the feasibility of this strategy in some acreages mitigating access to parts of the reservoir.

A customer in the Eagleford Shale Basin had two unique wells where a second lateral had been created parallel to the first one in the same formation. Standard unconventional shale wells are generally L-shaped in layman’s terms. However, one of their wells resembled a “w”-shaped lateral, while the other resembled a “u”-shape. These extraordinarily shaped laterals were created with the objective of obtaining equivalent treatable lateral lengths in a lease with short widths.

The customer required a thru-tubing service that would drill out 32 frac plugs in the w-shaped well with a measured depth (MD) of 17,846 ft, and drill out 38 frac plugs in the u-shaped well with an MD of 21,064 ft respectively.

The major concern, however, was getting to bottom to drill and clean out all frac plugs to ensure production from all stages.
