A2(Sama) exploration or Appraisal, page-17

MMM

The topo is self explanatory if u refer April slideshow on Erin's website. One structure is closed off at the northern fringe of A2 followed by a gas & then a re-emergence of the crest where Sama is mapped out. In my view u r looking at an erosion episode which appears to b the case for these platform hosted Buried Hills (or call it a 'Saddle' between 2 crests).

Another observation on that topo is that SNE's Oil water contact is at 2681m. So, there's about 200m potential reservoir section missing north of Sama on that topo (most likely erosional topography) & where u saw that 'fault' closure.

The depth mapping of the section from 2500m seems well preserved at Sama given the recent 3Dseis by both parties using Polarcus Alima at A2 in Sept2015 and Poalrcus Adira at Sangomar by Cairn.

Still the JV needs to drill a Discovery well first & recover fluid samples via the MDT probe  & back it all up with the res-gamm-density wireline logs.

Also at SNE the JV needs to define the southern end of the field perhaps via stepout drilling south of SNE 5. This can b done at a later date for phase-2, as they seem to b happy with meeting the MEFS criteria.

Hope this helps.
