Agreed. However, the last well I did with them they lost 3 BHA's down hole never to be seen again. This was partly due to an over zealous rig Operator over ruling Schlumberger recommendations when drilling through tight hole conditions.
So it still has risk even with the best in the business steering the bit. It only takes one cog in the chain to fail for things to turn sour.
Judging on previous wells and how the BOM operate, I don't see this as being as an issue.
March 30 2007-The well was drilled to a depth of 2,683 m and encountered a pay zone of about 35 m in the TAGI sandstones. Schlumberger Ltd. carried out a 27-day flow test in which the average sustained flowing bottomhole pressure was about 20 bar at gauge depth with a 1-in. choke.
Triassic TAGI reservoir was Lone Star's primary target for its SBK#1 well. It was encountered between 3,425 and 3,505 meters and two zones were selected for further tests and modeling. Reservoir pressure on a DST showed 7,175 psi, for a potential production rate of 2.5 million cf/d gas and a relatively small levels of oil.
Where have you found info to suggest that Te-2 is connected with Te-6? The only thing I've found so far says that Te1 was drilled in 1966, Te-2 in 1967 and Te-3 in 1985. All three had slight gas shows but none were tested properly. The fact that every hole drilled in the region has gas or gas and oil shows has to be good news. I'd assume that gas has become more desirable and technology has moved on since 1967!
