The Product

The Multi Set Wireline Plug (MSWP)

The Multi Set Wireline Plug (MSWP) is a high-performance plug designed to set, equalize and retract multiple times during the same run. The plug will increase the efficiency and performance of the work scope and save rig time. The MSWP features a proven elastomeric element and a robust anchoring module, both of which are based on our existing ME.

The MSWP is run and set with the Multi Electronic Setting Tool (MEST), operated and powered from surface using Electric Line. The operating parameters are displayed live at surface, and the MEST’s built-in memory logs performance parameters. These parameters include stroke position, temperature, internal pressure in both setting chamber and retraction chamber, motor rpm, voltage and current. This helps to create a setting profile, which can be used to evaluate setting area in well, equalization, retrieval and setting status of the plug. The plug is designed to withstand a
differential pressure of 5000 psi and temperatures between 4°C and 150°C.

Application

The MSWP can be used across a range of applications, including; leak detection, ASV release, set production packer, testing perforation zones, barrier in wells with integrity issues. When used together with Interwell’s multi electronic setting tool (MEST), the MSWP can set, equalize, retract and re-set multiple times in the same run (multiset mode).

The MSWP will be connected to the MEST during multiset mode. When the plug has been set, equalized and retracted the required number of times, it is possible to fully set the plug and disconnect the setting tool, leaving the plug to act as a barrier in the well.

Key Benefits

Set, equalize and retract multiple times
Simplified Integrated Operations with IO-Centres
Performance increase of plug scope
Save rig time
Compatible with a range of add-ons including IBV, BVS, POS, IPD and ITD
Compatible with a range of wireline tools including tractors and calipers
