Block Energy plc announced it would soon test well WR-B1a following completion of drilling operations and that a second well for 2021 was also being prepared at West Rustavi, Georgia.
WR-B1
WR-B1 was initially drilled to 2,180m and encountered hydrocarbon shows higher in the Middle Eocene reservoir than expected.
The company said that shows continued to increase in frequency and magnitude, but wellbore stability required the section to be re-drilled and WR-B1a was extended to 2,483m over a reservoir interval of 478m.
Following 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.
POTENTIAL
“Preparations for rigging down the ZJ40 drilling rig are now underway, to enable the installation of the Christmas tree over the wellhead,” said the company in a statement.
“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.”
Block added that the WR-B1a well was potentially transformative for the company, 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 Block’s early production facility for processing to allow “rapid monetisation of oil and gas”.
CHALLENGING
Chief executive Paul Haywood said that the company had recorded zero lost time injuries out of 280,000 man hours worked this year.
“It is well known that the Kura basin is a complex and challenging drilling environment and to have successfully reached TD is a solid reflection of Block’s capacity to undertake such operations.”
