In CLR's 2Q21 conference call, COO Jack Stark made an interesting remark: Continental's COO - Jack Stark - said in his introductory comments
st the 2Q21 Conference Call the other day that 'exploratory opportunities'
were underway that could greatly increase CLR's size.
Could possibly be the forgotten Tuscaloosa Marine Shale.
A tiny Australian company has drilled 6 wells there with moderate success.
Could be interesting.
A reader suggested CLR could be thinking about the Tuscaloosa Marine Shale, which prompted a very, very long post.
Continuing that conversation, that same reader replied.
From the reader:
Reading your TMS posts today have really fired up my imagination.
From memory, and a LOT of connecting the dots ...
TMS was determined by a local university geology department to have about 8 billion barrels recoversble oil.
One (of several) challenges with the TMS is the depth ... 14,000 to 16,000+ foot depth, if I recall correctly.
Next
biggest obstacle is the frequent 'caving in' of the wellbore as it was
being drilled ... especially during the build/curve. (Big, unexpected
expenses there ).
Many 'unkowns' that can only be discovered
through expensive, nerve-wracking trial and error include optimal
landing depth, depth of curve initiation, (and angle), mud parameters,
rate of drilling, identification of 'sweet spots', and several more.
Now, the 'good stuff' ...
Oil cut is 92% / 96% ... extraordinarily high.
(Bakken which is high, runs 85%/90%). -- in the early Bakken, I believe the cut ran as high as 94%;
Best
part - in 2 aspects - is that the extreme depth has VERY high formation
pressure which greatly 'pushes' the oil out of the rock and into the
wellbore.
Now, with recent advances in Gas Lift technologies
(gas lift seems to be near universal in the Bakken now), single point
(relatively cheap) high pressure gas can be injected down to the curve
which will zoom up to the surface bringing a ton of oil with it.
To
rephrase ... while the very deep TMS poses inherent challenges, those
very same characteristics can be huge positives when considering
- getting the oil out of the rock and into the wellbore
- having the deep gas injection prompt huge expansion/lift by which the
liquids can (somewhat easily) travel 3 miles up to the surface.
As
you say, I may be getting ahead of my headlights here, but I suspect
the emerging technologies these past few years that have been developed
in the Bakken (drilling, completions, geological assessments, artificial lift) may have produced a viable climate within which to further tackle
the TMS.
As an aside, other formations such as the Rogersville, Paradox, et al may start to kindle interest for the adventurous.
