"IF the results come up negative and we somehow hit a dry area, what is the likely outcome? "

Thoughts....and 100% my opinion only. IMO the two main reasons that M2 might fail"

1) failure to obtain a sample to surface due to tight reservoir

Low risk based on M-1 preliminary log interpretation.

2) failure to obtain a sample to surface due to hostile hole conditions.

The main risk IMO but mitigated to some degree by learnings from M-1 and revised mud parameters. Also mitigated by having SLB handling wireline rather than Baker. In a worst case scenario where we can't get samples with the MDT tool on wireline we have the fallback option of running the tool on drill pipe. Expensive and time consuming but I've done a fair few TLC MDT jobs over the years and managed to get the data and samples in the bag. TLC looks complicated and scary but its well within the capabilities of a good wireline and rig crew working together.
