LOSE THE RIG, NOT THE ESP
 

COLIBRI CABLE-DEPLOYED RIGLESS ESP

The Colibri rigless ESP system requires only reinforced carrying cable to be deployed and retrieved. All operations can be conducted on modified slickline equipment. There is no need for a rig, making it a truly rigless electrical submersible pumping (ESP) system. Saving both time and money, cable deployment enables operators to resume production quickly without having to kill the well. The short-term result is a decrease in deferred production without having to wait and pay for the rig required in standard ESP operations. The long-term implications include eliminating rigs from ESP installations altogether, reducing risk, and lowering the number of personnel required to install ESPs.

Rig-deployed ESPs take time

ESPs provide reliable artificial lift for a broad range of flow rates and well conditions. They are one of the most reliable, efficient methods for increasing production in many well types. Installation requires a rig to be in place so the ESP can be run to depth on production tubing inside the well casing. This is not a problem during well construction while the rig is already onsite. But if an operator has to pull the ESP for any reason, it requires scheduling and mobilizing a rig, killing the well, and pulling all the production tubing along with the ESP. Then the crew runs a new ESP and replacement tubing to depth and the well is turned on again. This process can take days. In land wells rig costs are relatively inexpensive, but rig availability can lead to significant production downtime.

The offshore ESP conundrum

In offshore and remote wells, the days it takes to kill the well, pull the tubing, replace the ESP, and run an ESP back in hole can be costly. In fact, the costs for installing or replacing an ESP in an offshore well are often so high that the operation is not economically viable. In too many cases, operators are leaving hydrocarbons behind because they don’t have an economical way to produce their wells.

 Just getting a rig onsite can be a challenge and can take days or weeks. Every day spent waiting translates into a day of deferred production, potentially costing operators hundreds of thousands—or even millions—of dollars.

 The minute a tubing-deployed ESP fails, it starts costing an operator production revenue. The time it takes to mobilize a rig, change out the ESP, and get the well back online causes major lost production revenue to operators who use ESPs.

 The fact is that rig-deployed ESP technology—intended to enhance production—can actually be a liability if the ESP fails. In many offshore wells, operators have traditionally shied away from using ESPs because they simply do not provide enough reward to justify the associated risks.

 

Lose the rig, change the economics

The Colibri cable-deployed rigless ESP system eliminates the greatest risks associated with using ESPs in high-value and deep offshore wells. It is deployed and retrieved using reinforced carrying cable, eliminating the need for a rig altogether.

 Recent results indicate that Colibri installation is up to five times faster than a typical rig-deployed ESP installation on land. As illustrated in the graphic below, the economic advantages of the Colibri rigless ESP increase dramatically in offshore and remote wells.

The process is fast, reliable, and can be carried out under live-well conditions—eliminating the need to kill the well. The thru-tubing ESP is deployed through a surface lubricator and lowered inside the existing production tubing. The Colibri system can be easily retrieved using only the cable. So, it can be used temporarily to keep production flowing and then removed when a replacement ESP arrives. Or it can be left in hole permanently as the replacement, providing a way to extend the economic life of wells that would otherwise be plugged and abandoned due to workover and rig costs.

This technology also reduces health and safety risks. Instead of the full crew needed to run a rig during tubing-deployed ESP replacement, the Colibri system can be deployed with only three or four onboard personnel.

Leading the rigless ESP race

The Colibri rigless ESP has the potential to change the way ESPs are deployed across the industry. Installing thru-tubing ESPs on cable offers time, cost, and safety advantages that will likely make standard tubing-deployed systems a thing of the past. Some new well designs now include a saddle for the Colibri system that is installed with the completion for future use. This enables easy access to install, replace, and remove Colibri systems under live-well conditions throughout the life of the well with no need for rigs or rig personnel. By giving operators the flexibility to add or remove the ESP at any time, this technology eliminates the greatest economic risks associated with using ESPs offshore and extends the economic life of wells that would otherwise be plugged and abandoned.
