Portland HH1

Consequently, with daily flow rates from production start at Horse Hill averaging over 300 barrels of dry oil per day ("bopd"), asset-level opex, inclusive of tanker export, sales and marketing, now equates to $17/bbl.

These include interventions to add commingled Kimmeridge oil flow. If successful, the resultant incremental production will further reduce the field's overall variable opex costs per bbl.This indicates the above flows of over 300dopd are from the Portland Horizon
Prior to the Kimmeridge production switch, which was necessary for the safe drilling and coring of HH-2/2z through the Portland reservoir, total aggregate Portland production reached 29,568 bbl, with HH-1 continuing to produce dry Portland oil at a stable rate of over 220 bopd. Preliminary Company analysis of the final Portland pressure build-up test, indicates that the Portland connected oil volume accessed by HH-1 has significantly increased from 7-11 million bbl to 11-14 million bbl, a robustly commercial volume.
From the above it must be conceded we are getting 300 + barrels per day from the Portland HH few feet of perforation and in fact it tallies all the way back to .
Independent oil consultants Xodus Group's ("Xodus") analysis of flow and pressure data interprets that further HH-1 Portland vertical well optimisation could achieve a forecast sustainable initial 24/7 pumped rate of around 362 barrels of oil per day ("bopd")* when full scale long-term production commences, exceeding original estimates. This analysis is key as it establishes the absolute flow potential of the Portland reservoir for future production wells.
Kimmeridge HH1

"The two Kimmeridge oil pools (KL3 and KL4) in the HH-1 well are now recognised to be one single accumulation 358 ft thick, as evidenced by fluid and pressure data."
Rns 12 September
" Prior to the current shut-in, Kimmeridge test production reached a total of 36,559 barrels ("bbl") of dry Brent quality crude at a final metered rate of 313 bbl of oil per day ("bopd") over the final 48 hour test period. Peak instantaneous rates of up to 374 bopd were recorded during this period. Total aggregate Portland and Kimmeridge test production now stands at a landmark 66,127 bbl. Kimmeridge production is planned to continue during the drilling campaign. "
Rns 1st August
Kimmeridge oil flow was re-established at initial half-hourly metered rates of up to 332 bbl of oil per day ("bopd"), with continued stable production of dry oil at daily rates of 200-266 bopd. Total Kimmeridge production to date, now exceeds 30,618 bbl with no apparent produced formation water. Following a 5-month shut-in, flow rates and flowing bottom hole pressures appear more stable than during Phase 1 Kimmeridge testing.
