WL logging for a 2072m (6800') TD doesn't take long, the update says 'interpretation'. They should b able to read the net/gross pay pretty quickly. Question is which zones has got movable HC's present & what's the reservoir property over that interval.
The openhole at Winx-1 should b apprx 4300ft in length (i.e, from 2500ft which was their last casing point to final TD of 6800').
So the Operator will run multiple tools & collate as much info as they can depending on their logging contractor (Halib'ton, Sperry, Baker or SLB).
If there r multiple zones of interest, then they'll run something like a triple combo tool first, then the MDT probe & if reqd take side wall cores (SWC) since they haven't drilled a sidetrack to core the main reservoir.
The swc's look like champagne corks so r sent off to the lab for poro/ perm measurements.
The MDT tool can take time for multiple zones as they stop & seal the pressure pads & take a jab of fluid so its like a mini-DST as it measures pressure, drawdown, perm & obviously the fluid content. Data from the SWC's & MDT fluid as well as production test is whats reqd to lock in a Contingent Resource assuming the net pay is thick with oil (& not water bearing). GLTA"...
Very interesting.
