Cenkman 08:15,

the power cut would have been the wireline units power system. Our well like any well is just a hole in the ground which the wireline team arrive at and throw their equipment down. Wireline are self sufficient, they just need fuel, food and a place to sleep.

Rigs do have power cuts also, can be avoidable by having preferencial trips (turn off the heating before the pumps etc) and sequential starts (after a blackout, turn on essentials like air compressors, fuel pumps first etc).

The wireline equipment was stuck in the well, perhaps caused by powercut and standing still. In the 8-1/2" hole they had 4" tools with wheeled legs (point your elbows out - wheels on elbows, you are the 4" tools) anyway, the claystone can swell and collapse when opened and left for days, then sandstone smothered in thick drilling mud 'cake' is also sticky when the weight of drilling fluid is higher than formation pressure (differential pressure sticking - tools are sucked against sandstone) so it is high risk for 88Enenrgy to say 'lets do another wireline run' once bitten, twice shy etc. In my mind, when I read the ANN on Monday evening I was happy enough with the oil find but knew the SP would tank. My quick thought was they had seen enough, have their plan B in the background and decided not to risk millions of dollars (share holders cash) on lost wireline equipment. Other thoughts were, to free the wireline they would have pulled hard on the 5200 ft long wireline cable... damaged cables, couldn't continue... who knows. The wireline cable is stronger than the weak point 'rope socket' at the top of the wireline toolstring. Now if we had left wireline tools in the well, the law requires you to make several attempts to recover them when nuclear sources are used (more cost - working time available etc). Perhaps us shareholders should be thankful 88Energy have not left behind a train wreck to fix next year.

This is well known in the oil industry, big customers like BP and Conoco are sent the good tool package and best men, small one well a year outfits like 88Energy get the left overs, just a fact of life and good business sense.

Well testing wise, I had it in my head that the well test team would finish at PANR and come over to us, perhaps PANR had delays, meant no men or equipment for us? Been busy this week so I have not had time to over think this one.
