This is for the HHz2 Horizontal
RNS 23 December 2019
"UK Oil & Gas PLC (London AIM: UKOG) is pleased to announce the successful completion of the first phase of open hole EWT and associated well clean-up at its Horse Hill-2z ("HH-2z") horizontal well, in which the Company has an 85.635% net controlling interest. During the initial clean-up phase, HH-2z achieved initial rates of up to 1,087 barrels of fluids per day and oil cuts of up to 60%, demonstrating the horizontal's ability to flow at rates significantly greater than the HH-1 vertical well. Produced oil, brought to surface via an electronic submersible pump or "ESP", has been exported to Perenco's Hamble oil terminal for onward sale at market price.
RNS 09 March 2020
"Dry oil flow rates during the initial 48-hour "clean-up" period to date are encouraging, with metered daily rates averaging 223 barrels of oil per day ("bopd"). However, as is to be expected in the early clean-up stage of such a horizontal wellbore, both oil and associated gas rates have been very variable. Half hourly rates have thus ranged from a high of 778 bopd to a low of around 10 bopd during intermittent short periods of "slugging" (i.e. the return of discrete pockets of gas and/or completion fluids).
The water ingress problem meant that HH-2z remained shut-in for almost 3 months, with spent drilling and completion fluids within the near wellbore. Consequently, it is expected that the full clean-up process is likely to take a number of weeks of aggregate flow. As part of the clean-up process, to ensure the full remaining horizontal section contributes towards aggregate oil flow, further interventions are planned to help fine-tune and optimise flow from the well."
Note that the well was shut in before cleaning up and the half hour rates 735 to 10 barrels will still yeald good results.
The biggest thing I took from the RNS of 23rd of December was:-
Downhole pressure gauges also confirmed that HH-2z penetrated a near virgin pressure section of the Portland oil pool. This finding has likely positive implications for the magnitude of connected oil in place and recoverable reserves seen by the field's two wells. Determining the oil volume connected to HH-2z remains a key EWT objective."
All very good for me
