Sealing and Curing Losses

(1) After TCP perforation or reperforating { shoot & pull }
(2) After a DST, after a frac job & after a gravel pack job & prior to p.o.o.h.


1- Killing a well prior to a workover:

In case of a workover being: a change or repair in pump, a change of producing string, adding new perfs or reperforating etc. the following need to be done:
Displace the pill all the way down the tubing using the Thixsal-Ultra viscous carrier ahead & behind to the top of the SSD.
a- you may either spot it out of the tubing & into the casing above the packer, then unset the packer and allow it at least 30 minutes to gravitate down and seal at the formation face
b- or you may displace it to the SSD top, close this one and bull head the pill till it reaches and seal at the formation face and a sudden increase in pumping pressure occur .

Once your perfs are sealed and losses are cured . p.o.o.h .
You may run now a new completion string and or a TCP / DST string to perforate and test in a shoot and pull or drop.


2- Killing a well after a workover:

In case of a shoot & pull, you need to remix a new pill based on new perforated interval length & displace it downhole to protect the formation against losses prior to p.o.o.h.


3- Controlling losses after a Frac job & or a Gravel pack job:

After a frac job and prior to p.o.o.h, since losses are expected due to the tremendous increase in the K factor, a pill need to be spotted to seal at the frac proppant face, this pill will be designed based on the propant size used and is not harmful to the frac & is compatible with materials used.

After a Gravel pack job and prior to p.o.o.h   with string to run completion, the formation need protection against losses. The best way is to pump and seal with the Bridgesal-Ultra pill inside the screen, thus stopping all losses to the newly gravel packed formation. The pill will be designed based on the screen gauge size used.
