When the logging company Anega won a tender to do a series of PLTs in horizontal, production wells in Kazakhstan, they selected Welltec’s e-line 218 Well Tractor conveyance solution to save time and minimize operation costs. The conventional CT solution required ~four days operating time, hence the savings potential was significant.
The toolstring was run in hole in logging while tractoring (lwt) mode to target depth, providing higher data accuracy and real-time feedback during the operation. The Well Tractor provided good depth control, constant speed for the downpass and saved valuable rig up / down time.
The operation was carefully executed at a slower-than-normal pace to allow continuous reassurance of logging capability, yet it only took 27 hours per well – a significant time saving compared to CT conveyed logging.
