Time to refocus on Balcombe after so many false starts…its truly worthy of a Hollywood movie.
So UKOG are about to do an EWT on their Kimmeridge play at Horse Hill, but they have already conducted a flow test back in 2016. These are the highlights from UKOG themselves.
* Based on the analysis of published reports from all significant UK onshore discovery wells, the Company concludes that the 901 bopd from the Upper Kimmeridge zone is the highest stable natural dry oil flow rate from a single reservoir in any UK onshore new field wildcat discovery well
* High quality Brent Crude produced: light, sweet oil (40 degrees API in Kimmeridge, 35-37 degrees API in Portland).
* Preliminary analysis confirms that the Lower and Upper Kimmeridge Limestone units are naturally fractured reservoirs with high deliverability
* Strong possibility for further optimisation and increased flow rates from all 3 zones in future development and production wells, particularly through the use of horizontal wells.
Now the big difference between what UKOG did in the Upper Kimmeridge at HH back in 2016 and what Angus are going to do at Balcombe is the well angle and the perforation / exposure interval.
Horse Hills’ Upper Kimmeridge Limestone was only perforated for 88ft…..yes thats correct only 88ft of exposure and had stabilised dry oil rate of 901bopd.
Balcombe is a horizontal well and with its slotted liner (pre-drilled holes) is exposed to +/- 1,700ft of Upper Kimmeridge Limestone. That’s 19 times more exposure than at Horse Hill who observed 901bopd from only 88ft.
This will be the Wealds FIRST horizontal flow test of the Kimmeridge Limestone. Our competitors have only drilled exploration wells and still need to drill a production well which has caused them issues in the past (Broadford Bridge).

Vonks said “ If you go to the North, Horse Hill flowed about 1,200bopd in aggregated from 2 limestones in the Kimmeridge, but its thinning out to the North. If you go to the centre where Balcombe is, it is 50% thicker, it was depositioned at a deeper depth, the maturity is better, so the conditions to make are better, so Horse Hill it was great; at Balcombe it should be much better
Now Vonk says Balcombe is 50% thicker than Horse Hill, but in Angus Jan 2108 presentation it states 25%.
This presentation is great to summarise Balcombe and also has graphics to compare Balcombe Kimmeridge with other Fields including Horse Hill.

* Horizontal well drilled through best limestone in it thickest Kimmeridge layer in the centre of the Weald basin
* Received planning permission to switch it on
* Balcombe increased Angus Energy Energy by 3 times
* Angus now Operator at Bal
