Temporary Well Kill/Reverse Kill technological procedure is needed every year for 100% of all wells for yearly scheduled standard well’s maintenance and acid treatments, for Enhanced Oil Recovery (EOR) of depleted productivity restoration, for water isolation for water isolation from hydrocarbon layers, for wells services and repairman works, for drilling operation, etc.
Conventional methods:
In well killing treatments by conventional methods with plugs and cement blockers the pump and tubing have to be removed for putting plugs into the well.
The plugs, used for this process, are very heavy; killing wells by these methods are very difficult, expensive and very time consuming. Conventional well kill/well restoration procedure takes at least a few days (depending on well’s depth and structural specifics), excluding well all this time from hydrocarbon production and often increases the undesirable water leakage into well and mixing with oil.
To eliminate this problem can take sometimes up to 2 weeks. In order to reverse the well kill, the kill fluid must be displaced from the well bore.
Newest proprietary patented Well Kill/Well Reverse technology:
The innovative patented environmentally safe biodegradable chemical compositions are used for well temporary well killing/kill reversing and there is no need for mechanical equipment to be used.
The time needed for injection of chemicals and salt solution for well killing is about 2 hours only and there is no need for pump and tubing displacement.
First, our proprietary patented light weight, EPA approved, environmentally safe, biodegradable chemical compositions are injected into well, changing into jelly film and creating the isolating layer above perforated zone. The jelly film isolates the well’s formation liquids and gas at the perforated zone top. Isolating durability of jelly film can last up to 9 months.
No additional equipment, no rearranging or moving of well‘s standard maintenance equipment is needed, saving the valuable days for well’s productive operation.
The reverse kill well procedure takes 2 hours, restoring well’s production and without any water leakage and mixing with oil.
To reverse well kill, to open well quickly, just the 2% solution of organic citric acid is used to wash out the injected compositions and open well. Just 4 hours will take to close and open well’s production. This is the cheapest, quickest and environmentally safest method to close and open wells.
