- Drilled 16” ( 1.30 sg) & 12” (2.10 –

2.25 sg) holes section with OBM - NaCl

& Using BARITE as weighting agent

and drilled 8” hole section with

OBM -CaCl2 @ 1.47 – 1.50 sg using

CaCO3 and BARITE as weighting

agents.

- CO2 gas was controlled to avoid any

contamination of OBM by treatment

of mud to maintain good properties.

- Used separator/ POORBOY & Degazer

to separate CO2 gas, issue was fixed.

- successed.
