Ann: Mukuyu-2 wireline logging progress update, page-136

The two depths reference to different reference point, so the higher number is measured along the length of the borehole, and the smaller number is called “true vertical depth” converting the along hole depth to true vertical depth accounting for wellbore deviation. It has nothing to do with column height.

my interpretation of this graphic is that they pumped below the fluid dew point and condensate dropped out, giving the oil/condensate signal after the gas signal. Phase separation before sampling will not give a representative sample as you are leaving some of the condensate behind. You always want to sample single phase. They saw this, stopped pumping after conferring with town and then found it was sticky getting off the wall. Made the smart decision to go TLC because this sample is shallow, the problem will only get worse with depth.

they will not have a sample on board.
