Codeco-Vanoco Engineering – Completes Successful Liner Install for Mining Paste Holes


These translations are done via Google Translate

Liner Operations

Codeco -Vanoco Engineering Inc. (CVEI) is pleased to announce the successful completion of two liner installations on existing paste holes for a mining client in Northern Manitoba, Canada

The wellbores were drilled previously by CVEI at an inclination of 60° (from surface) to a measured depth of 870m (2855ft). Recently the 219mm (8⅝”) casing was evaluated and determined to be compromised due to the abrasive nature of the paste being transported through the casing.

Codeco-Vanoco Engineers conducted several  field visits  to observe the site and the existing facilities at surface and underground.  The option of drilling two new paste wells was quickly eliminated because of limited space due to the permanent facilities to accommodate the drilling rig and overall economics. Working with clients engineering department a decision was made to re-enter the existing wellbores. This allowed the client to continue pouring  while repair work was being performed on the other paste hole.

Surepoint Group

Codeco-Vanoco Engineering Inc. selected   TNT Power Tongs from  Edmonton, Alberta Canada to  design and manufacture a casing jack (patent pending) to accommodate the limited working area and satisfy the downhole requirements. This casing jack configuration along with other associated equipment allowed us to design a bottom hole assemble (motor, mill ,139 mm (5.5”) work string) to clean/ circulate debris from wellbores.

Two 152 mm (6”) coated liners 3m ( 10 ft) in length were successfully run inside the 219 mm (8⅝”) using the casing jacks and grouted to surface.  The project was on budget and minimal delays for poring were incurred. This accomplishment will allow other mining/energy companies to have confidence in workover operations on existing well sites with limited access and  underground  challenges.

Codeco -Vanoco Engineering Inc. has been a leader in providing engineering and project management to the energy and mining industry for over 30 years in Canada and the U.S. through our subsidiary Vanoco Consulting LLC based in Denver, Colorado.  Our experienced technical teams can provide engineering and consulting services to all industry sectors including sustainable energy projects.
