What is CMCD?
Controlled Mud Cap Drilling (CMCD) uses sacrificial fluid and heavy mud to manage total losses. EC-Drill® enables straightforward CMCD operations and smooth MPD transitions.
CMCD is Controlled Mud Cap Drilling. This is a method of addressing total losses on a well using a sacrificial fluid to drill the reservoir and a heavy mud monitored in the annulus. With EC-Drill®, it is straight forward to use this method to address total losses on a well and has an easy transition to and from conventional drilling and MPD with EC-Drill®.
