but it's still about how much recoverable oil there is and at what rate it can be extracted!

With that amendment, that's exactly my point! And there will be uncertainty about that for some time.

Peter,

All you say is true, and well known to us, but it's still about how much oil there is and at what rate it can be extracted!

Stril polar left Aberdeen 4am back to rig with supplies

Good find CC

One Q: how does the Competent Person in this case determine P50 reserves when an EPS is required to better understand the reservoir characteristics......is there not an apparent contradiction here ?

[laserdisc] 31/1/2017 16:59

Thanks for the info re reservoirs hur report large oil columns and with it being low viscosity the oil flows better, so the fractures should fill up quicker when they are drained, must be a massive network of fractures let's hope it all comes to fruitition

tgg re 100,000 bopd that's about 1.1bbls a second you know from a single wellbore !!!

[thegreatgeraldo] 31/1/2017 16:09

Point about the mooted EPS rate is that it's skimming a bit off the top - 17kbopd. If you had a sandstone reservoir in the NS with 300mmbbls, you'd start with production north of 100kbopd.

[buffythebuffoon] 31/1/2017 15:29

That applies to all reservoirs tgg !

Didn't they say it flowed under natural pressure, at more than 6,000bpd and far more with assist? So it's there. Just how much can they get at?

Silicilastic reservoirs have markedly higher propor- tions of both high porosity values (>20%) and high permeability values (>100 md). Forty percent of all points in Figure 4A has porosity greater than 20%, vs. 6% of points in Figure 4B, whereas 47% of all points in Figure 3A has permeability greater than 100 md vs. 28% of points in Figure 4B.
Carbonate reservoirs have a greater relative pro- portion of high permeabilities at low porosities. Four percent of all points in Figure 4A have both per- meability greater than 100 md and porosity less than 15%, vs. 20% of points in Figure 4B.
Both lithologies include a subordinate group of res- ervoirs with multidarcy permeabilities at porosities below 15%, which we suspect to reflect fracture instead of matrix values

I hope the above is of some help. But what it comes down to in the end I suppose, is what amount of oil can be contained in a given field, eg, Lincoln?

[ngms27] 31/1/2017 12:52

A good sandstone reservoir would have porosity around 20% give or take, so you could argue that any structure would have to be 4 times the structural enclosure of a similar sandstone reservoir to contain the same volume of hydrocarbons.

However the Worlds largest fields are in Limestone with average porosity around half that of sandstone.

The problem HUR have is proving that the fractures extend throughout the reservoir. The EPS or additional wells can materially prove this.

Thanks for your comments lads!

Bloodhound I took ngms' comment to mean that a result which was a standalone successful well, may not necessarily mean much share price appreciation and given the risk of a duster (however small), it was worth taking some money off the table now.

[puffintickler] 31/1/2017 11:22

I'm not knowledgeable on the subject but I would have thought that the recoverable oil is essentially a function of the extent (volume) of the fractures. A fractured formation holds oil in the spaces between rocks. Once this has been removed it is hard to imagine that much will come out of the rock itself even if it is reasonably porous.

[bloodhound] 31/1/2017 11:17

ngms27 - Lancaster and Lincoln are both known knowns and Halifax right now is an unknown known.

I'd say "Probably hedging their bets given the COS of Lancaster and Halifax being connected is probably less than 30% given the seal requirements." would be an alternative truth;-)

Halifax as a stand alone successful well is just fine by me, one giant connected field really would be the icing on the cake.

Depends on the size and extent of the fractures in the granite and porosity of the sandstone.

However HUR aren't drilling Granite, try this:
