A few notable accomplishments are as follows:<\/p><ol><li>A major operator was able to drill a subsea completion well hitherto considered one of the most challenging types of wells, with acceptable losses. The pore pressure encountered was 5.6 \u2013 6.0 ppg whereas wellbore stability required 9.6 \u2013 9.8 ppg mud. The well was successfully drilled with ~9.8 ppg mud, without encountering losses. The system was used to drill the pay zone and a production rate of ~ 170,000\/- M<sup>3<\/sup> of gas\/day evidenced the fact that there was little to no formation damage during drilling.<\/li><li>A major operator has drilled several wells covering multiple formations with varied pore pressures, in a single section. The formations included fractured shale and limestones. Some of the zones encountered were pay zones which after prolonged production have become sub-hydrostatic. These zones have a pore pressure of 5.0 \u2013 6.0 ppg, the intermediate section has a pore pressure of ~ 9.0 ppg, and the target zone has a pore pressure of ~ 8.3 ppg. All these formations were drilled as a single section of 300-400m with mud weights ~ 10.2 ppg successfully, with acceptable mud losses and no hole collapse issues. Offset wells of similar construction routinely experience mud losses to the tune of 110,000\/- bbls in this section.<\/li><\/ol>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>THIXOTROPIC FLUID &#8211;
