The technology of performing fracturing jobs without pooling packer out for maintenance allows following:
- To Reduce term of putting of well on production from drilling from 28-30 days
(with tree layers field development) till 12-17 days
(depending on quality of performed frac job (presence of screenout in tubing and,
accordingly, number of coiled tubing runs)
- To Increase responsibility of frac performed contractors for qualitative carrying out of frac job,
i.e. performance of good design of frac operation and absence of not displaced send in tubing
(as a rule, RCP, the most expensive in frac job);
- To Reduce requirements for coiled tubing equipmnet twice, and accordingly, reduce expenses for them;
Ease of packers unsetting has allowed customer to refuse from expensive workover rigs "IRA" with capacity
of 100 tons (at average depth of well of 3100 m and a max. angles of deviation up to 65 degrees)
that also has led to considerable decrease in expenses.
Patent of RF on invention is received on given technology.
