WHY ARE WE STILL HERE ? - A CIRCA 2011 POST FROM 'BBBS' - PART 1.18 Dec 2025 17:09
Hello all, long time no see. I've been 'otherwise engaged' of late - have I missed anything? Well, after an intensive catch-up, it seems to me that one or two things have been missed - or perhaps some people just have difficulty with focus (for whatever reason!).
Where do I begin? Well, for me, the size of GKP's success is still all about whether the Jurassic is filled to spill, i.e. where is the OWC and/or how deep are we now concerning LKO (Lowest Known Oil) in the Jurassic. This does not mean that the Cretaceous, Triassic and Permian formations are irrelevant; just that the volumetric (OIP) consequences of a deep Jurassic OWC in Shaikan are overwhelming in the context of what will most likely be present in ALL of GKP's four blocks (Shaikan + Sheikh Adi + Ber Behar + Akri Bijeel). In other words, my focus is on the big picture for the Jurassic as shown in slides 15 through 18 in the May 2010 Investor Presentation. I have posted about this on several previous occasions ... it is the main driver behind the BBBS POTENTIAL button on spidey's NAV calculator.
So whilst I can understand the disappointment of some concerning the poor initial flow test results at Sheikh Adi, I am surprised that the focus has been mainly on this and not on the fact that the well is full of oil - moveable oil - throughout the Jurassic and into the Triassic (RNS of 23rd May "Prior to reaching the Triassic, logs and cores were obtained in the Jurassic sections, which show hydrocarbon saturations and where 45 meters of net pay have been calculated", "A core totaling almost 13 meters was recovered from the Barsarin/ Sargelu Jurassic section which had moderate oil shows", "A core of just over 12 meters was also obtained in the Butmah containing good oil shows", and "In addition, log data indicates moveable oil in the Sargelu/ Alan (obtained in sections deeper than the test zone), Mus and Butmah, all of which would be the target of a future potential test programme"). Ok, so there are less fractures in the down-thrown block, but (a) OIP resides predominantly in the matrix porosity - the 45 meters of net pay - and not in the fractures (fractures are great for providing a flow path from the matrix porosity into the well but the fracture porosity itself is almost inconsequential to the OIP volume - DGA did not even include any volumes for the fracture porosity), and (b), most importantly, there is NO WATER!
Think about how this fits into the big picture - in a massive structure the size of Shaikan-Sheikh Adi, there are bound to be some wells that encounter less fractures than others. And one has just been encountered, not unsurprisingly, in the down-thrown, less folded block, that sits between the main up-thrown blocks of Sheikh Adi and Shaikan. The most salient point is this: the down-thrown block between the Shaikan and Sheikh Adi main structures contains moveable oil, NOT WATER.
