The answer was no problem Jones as per my post ! You should be a journalist as you try to twist what’s said. And before you ask no I don’t have a problem with journalism. He he
He he. No problem I love foreign food curries especially.
You back again Jones ? What a life you must have giving a running commentary day to day watching from the sidelines! The John Motson of sound. He he. Snivel snivel. Don’t tell me you are another 10 pound an hour boiler room foreign boy ?
@ktf - keep an eye out for the position of keyboard warrior, you're a shoe-in
Thanks Aussieridge
I reckon ddboy and I could do a better job for £10/hour (each!)
why? do we need someone who can cut and paste ;)
I'm for offering Exploration a place on our BoD !
JOHN
I agree - the best prospects are all relatively close to TE-5 and could have increased the size of the developed area as a ‘cluster’ of smaller fields. However, Sound’s decision to ‘go for broke’ trying to discover more, bigger gas fields was never going to succeed. It wasn’t ‘bad luck’ or to be expected in the petroleum business’.
No - the root cause of Sound’s failures is second-rate subsurface analysis and failure to study and understand extensive previous work on reservoir effectiveness. TE-8 showed that features where the Tagi was deposited in a playa lake or alluvial fan facies. Without going into the details, the distribution of sedimentary facies is very variable and unpredictable, even over short distances (tens to hundreds of meters).
The available data from the wells suggest that the basin probably does not contain significant amounts of well-sorted (I.e. porous and permeable) sediments. Within the Tendrara area it appears that the alluvial fans developed as a consequence of initial rifting with main deposition occurring only locally. The morphology was levelled with progressing time and an extensive playa system covered the area forming the upper TAGI mudstones. Thus, an effective drainage area promoting braided streams and better sorting did not develop in the Tendrara area. Whether such a drainage system developed in general is very questionable since no indications of any clean fluvial sandstones have been encountered in wells to date I.e. nothing similar to time-equivalent Rotliegendes sandstone of North Sea or Sherwood Sandstone at Wytch Farm in UK.
The major faults will control the facies and thickness of the TAGI reservoirs. This model is based on poor seismic data, especially in the 2D seismic areas, and will only be improved with the widespread acquisition of high quality 3D seismic across the whole basin area. One wouldn’t do 3D all in one go - but rather extend it from known areas such as TE5 - eventually over a period of years the surveys can be ‘merged’ into a single survey.
In fact, the halite cement found in the Tagi in Sound’s dry wells probably formed before gas migrated from source rocks and therefore the reservoir was never charged in the first place.
Unfortunately similar processes in the Tagi took place in Sidi Moktar. Published work on the Meskala Gasfield in the Sidi Moktar area demonstrates this. 6 out of the 10 development wells on Meskala failed to flow due to halite pore occlusion. So while the proposed new seismic might define prospects the reservoir effectiveness risk still dominates the chance of success - just as it has in Tendrara.
This is hardly a popular share right now... The 19.3% indicated spread isn't really helping matters. :-0
There's gambling and stupidty.
easy to gamble when you're playing with someone else's money.
So why weren't these drilled before. What were JP and Brian playing at?
That looks like the plan
Morocco want gas by end of 2021, therefore we are production
We have at least 3 lower risk drills identified in Eastern Morocco. That they want to drill.
We will farm out sidi, 2d seismic then drill.
It seems that more drilling is a real possibility. Or am I miss reading all the signals here
