Geosynthesis Engineering successfully applies the Biocar-Block system during the scheduled CWO

Geosynthesis Engineering LLC has provided a Biocar Block system for well killing during capital workover (CWO), the company reports.

According to the report, this is the 90th well where the flushing systems of Geosynthesis Engineering LLC were applied. The entire volume of the fluid has been prepared according to a specially developed NDL recipe on the production base of Geosynthesis Engineering LLC.

The company noted that the purpose of the CWO was to recover the leaky packer and eliminate the leaks in the production string, through which water inflows in the well. The density of formation water coming in the well is 1,145 kg/m3. And according to logging data, the productive horizon V-18 is not flooded, whereas water comes from the upper intervals.

The company’s specialists also noted that the biopolymer solution Biocar-Block was chosen for killing due to the presence of water in the well. Under such conditions, the use of an oil-based solution could have a disastrous effect on the further productivity of the well and lead to the loss of the entire volume of flushing fluid.

As reported, the well was killed using a coiled tubing unit. The tubing was filled with Biocar-Block killing fluid and a specially designed blocking pack was set at the bottom.
