The Warwick West well was spudded on 24 September 2019 and was drilled to a total depth of 1,879 m TVDSS. It intersected a 931m horizontal section of fractured basement reservoir.
The well flowed for a total of 85 hours in a number of flowing periods at variable rates, using both an electric submersible pump (“ESP”) and under natural flow, while work continued to clean the well and evaluate reservoir performance. A stable rate usingan ESP could not be reliably measured as the well was stll in the process of cleaning up.
An extended pressure build-up period, a final flow period was conducted under controlled natural flow conditions which achieved a stable, sustainable rate of 1,300 bopd with evidence of the well having cleaned up further. During this flowing period, less than 0.5% water was produced.
Initial analysis of oil samples indicates a light, 43° API oil. Further technical analysis of PVT fluid samples will now be carried out. This will include comparing the geo chemical signature of oil from Warwick West with oils procured from Warwick Deep and Lincoln Crestal.
Warwick West is the third and final well of the 2019 programme on the Greater Warwick Area (“GWA”) which has been carried out using the Transocean Leader semi-submersible rig. In accordance with regulatory requirements, the rig will now plug and abandon the well before demobilising.
Hurricane and its joint venture partner on the GWA, Spirit Energy, are currently evalua$ng the results of the three wells drilled and tested in 2019. Further technical analysis will be required to determine the impact on the potental for the GWA to be asingle accumulation,and on volumetrics.
Lancaster EPS Operations
On 14 November the sixth cargo of crude oil from the Lancaster EPS was li>ed, taking total oil sales to 2.5 million barrels since First Oil in June 2019. Average produc$on for the remainder of the year is expected to con$nue to be inline with guidance for Q4 2019 of approximately 11,000 bopd, constrained by system availability and data gathering requirements.
As part of the datagathering exercise for the LancasterEPS, the Company has been carrying out periods of producton from the 205/21a-6 and 205/21a-7Z wells separately, to assess fluid dynamics and measure reservoir performance without the impact of interference from the other well. An interim update will be made when these flow periods have been completed, which is expected to be later in December 2019.
