We still need oil & gas......OUR CHRISTMAS TREE!9 Sep 2021 10:31
WR-B1 was initially drilled to a measured depth of 2,180m, encountering hydrocarbon shows HIGHER in the Middle Eocene reservoir than expected. Shows continued to INCREASE IN FREQUENCY & MAGNITUDE, but wellbore stability challenges required this section to be re-drilled. This was SUCCESSFULLY achieved, extending drilling of WR-B1a to 2,483m over a RESERVOIR INTERVAL of 478m! After careful evaluation of the frequency and magnitude of fractured zones penetrated, the subsurface team decided to call total depth, rather than extend the horizontal section further.
After encountering MULTIPLE shows and indications of hydrocarbon-bearing fracture zones, the well was successfully completed. A 7" pre-perforated liner with fracture-isolating swellable packers was set down to a measured depth of 2,161m and a 4½" slotted liner extends from 2,161m to 2,483m.
The reservoir was encountered within two metres of the prognosed depth, having utilised the latest 3D-seismic technology. Drilling operations were also optimised through the strategic partnership with BAKER HUGHES and the adoption of technologies, such as rotary steerable systems and logging-while-drilling.
Preparations for rigging down the ZJ40 drilling rig are now underway, to enable the INSTALLATION of the CHRISTMAS TREE over the wellhead. Once this operation has been completed, a production test will commence. A permanent downhole pressure gauge will be installed, with the aim of providing real-time data to OPTIMISE RESERVOIR PRODUCTION
The WR-B1a well is potentially transformative for Block, targeting an estimated 2.1 MMboe of recoverable oil and gas. In the event of a commercial well, production from the well will be tied into the Company's Early Production Facility for processing.
Block Energy plc's Chief Executive Officer, Paul Haywood, said:
"We are delighted to announce the safe completion of drilling operations on well WR-B1a, whereby zero LTIs were recorded out of a total 280,000 man-hours worked this year, against the added challenges presented by Covid-19. The operational team in Georgia has made significant progress with drilling operations on well WR-B1a, allowing the Company to now progress to the testing phase. ....... If the well proves to be commercially viable, which we hope to establish soon, Block could readily realise the return on its investment in well WR-B1a, having established Early Production Facilities, which will enable rapid monetisation of BOTH OIL & GAS.
