RE: Next news lower GOR ?5 Dec 2023 00:54
Next known news should be on the GOR at the SMDB vertical flow test, the timeline would have the pressure gauge retrieval, 6 weeks after the 19/10/23 RNS, around 30/11/23.
This is an input to GOR calculation and fluids recombination studies Geomark are completing, Bob Rosenthal further refines the timeline as 2 to 3 weeks from the 22/11/23 Webinar.
See source information copied way below.
The measured GOR, meaning, the actual recorded ratio in production is hugely reduced, from 12000 to 13000 scf/b in the Alkaid 2 zone of interest, to a much more attractive 3000 to 4000 scf/b in the SMDB.
What is not yet known, is how much of this is due to the slower draw down, lower differential pressure approach, to flowing the well at the SMDB, as a means to reduce in reservoir flashing, and how much is a reflection of, a simply lower reservoir GOR in the SMDB reservoir
I believe there is a hint towards also simply better, in the webinar statements.
Both will be positive,
A means to reduce production GOR by production method has been demonstrated, and should be meaningful to the economics
But a lower in situ reservoir GOR is the big one

We mentioned in the presentation that we will be updating a lot of our development planning to incorporate the re-entry into the Alkaid 2 well , PARTICULARLY THE LOWER MEASURED, AND HOPEFULLY RECOMBINATION SAMPLE CALCULATED GORs, will give us a clearer idea.

Netherlands Sewell have already you know stated, that that'll be a BIG PART of their evaluations going forward
Bob Rosenthal at 57:50
We have definitely shown the Shelf Margin Deltaic B is light oil, and then secondly, the GOR IS SIGNIFICANTLY LOWER THAN IT WOULD, YOU WOULD ANTICIPATE FROM WHAT WE SAW AT ALKAID, AND THE ALKAID 2 TESTS OF THE ALKAID ZONE, WHICH IS GOING TO HAVE A SIGNIFICANT IMPACT, ON OUR RESOURCE ASSESSMENT, and how we develop the field so leave it like that and pass over to Jay
IMO the writing is already on the wall, a better GOR can be anticipated. If so it will improve all areas of the Aphun SMDB reservoir calculations, the SMDB being far the larger volumetrically, and currently economically modeled on the poorer ZOI composition data
For example , lower GOR will reflect as, higher flow rates, better EURs, less reinjection wells
