RE: HH KL-3 testing16 Nov 2018 08:52
Imac1 - No worries.
I'll repost another 6th November post...but one thing I'll expand upon is the flow rates. I've taken UKOG 2016 flow rates from solely the Upper and Lower Kim whereas Angus will be perforating the large interbedded mudstone that is fractured and both UKOG / Angus believe connects the KL3 to the KL4. That will have a certain volume of hyrdcarbons not accounted in my 1,000bopd.
Also the fact I am taking UKOG flow rates from a well not specifically drilled to produce from the Kimmeridge.
I like to have a banker volume and anything else is a lovely bonus...hence I am using 1,000bopd as explained below:
"The added bonus is that Brockham was drilled specifically as a Kimmeridge producer with the correct hole size / drilling fluid, whereas HH wasn't due to it being an exploration well assessing multiple zones of interest.
That's a very interesting point as I've based my production rates on the HH 2016 test and not a standard production well with the correct sized hole, so Brockham should see better flow rates than the HH 2016 test
Brockam isn't a horizontal well, so I will go for a conservative figure of 1,000bopd.
UKOG (actually Angus did it for them) flow tested their deviated well in both the Upper and Lower Kimmeridge back in 2016
Upper Kim perforated 88ft observing 901bopd
Lower Kim perforated 80ft observing 464bopd
So they perforated 168ft and observed 1,365bopd
Angus are perforating 200m or 656ft of Kimmeridge.
That is 4 times what UKOG did.”
Vonk says at 6min 44secs
“Brockham is a carbon copy of HH. Brockham is drilled as a Kimmeridge Producer. HH was never drilled as a Kimmeridge producer. Hole is too big and used the wrong drilling fluid to get the best out of the reservoir”

What is the difference between Brockham and HH?
Brockham is deviated where as HH isn’t.
Brockham has more exposure to the limestone than HH.
Brockham was drilled as a Kimmeridge producer with the correct sized hole for optimum production. HH drilled through Kimmeridge section with much larger hole due to well design assessing deeper reservoirs beneath it.
Brockham drilled with correct drilling fluid for producing from Kimmeridge. HH used wrong drilling fluid as deeper reservoirs were the objective."
