Multifunction downhole barrier plug/valve
We have filed a patent application on a new product, that can be used in wellbores where a downhole barrier (plug or valve) are requested either as wireline inserted or as an integrated part of the well completion string.
A downhole plug/valve that will save considerable sums for the E&P companies
Features:
-
Wireline or coiled tubing installed/retrieved, or integrated as a well completion component -
As wireline installed barrier, the unit can use locks or slips, depending on well completion features present
-
Will hold pressure from below
-
Pressure equalizing or pumping through closed plug is possible by pumping fluids into well above barrier
-
A barrier that can be opened and closed as many times one wants, without any wellbore interventions
-
No need to mobilize a wireline crew, loose production etc. while rigging up, running into well, etc., to open or close the valve
-
A barrier that can be used in additional to bullheading the reservoir for well completions/recompletions or installation of insert technologies within existing tubing (as e.g. our own insert gas lift solution)
-
No electronics or batteries
-
No cable or control line to surface
Technology background:
Working with a North Sea operating company on our insert gas lift solution, a requirement for a downhole barrier in additional to bullheading (killing) the well came up. We thereafter came up with a solution to achieve this.
The solution is based on using standard components available from a number of wireline/well completion component suppliers, introducing a new innovative component and combining these.
We are seeking partners to design, build, qualify and introduce this product to the global wellbore market.
Patent pending.
