The well is now ready for production testing, the company added.
"We're pleased to confirm that operations at WR-38Z continue to proceed smoothly, with the well now flowing and ready for production testing,” said Paul Haywood, Block's chief executive.
“We look forward to updating the market on the results from the multi-rate production test.
“Furthermore, we are excited to have completed our 3D seismic acquisition and eagerly await the results of the processed data set, which will enhance our understanding of the reservoirs."
Block also reported that it has temporarily shut-in the WR-16aZ whilst production facilities are being upgraded. It is expected to return into production in January.
The company has already prepared the nearby WR-51 horizontal well.
3D seismic acquisition has been completed, data is presently being processed to better understand the subsurface and allow the identification of optimal future drilling locations.
Sam Wahab, analyst at SP Angel, in a note, said: “An encouraging update from Block today, with the latest well producing to surface.
“The company benefits from an enviable acreage position in Georgia and West Rusavi represents a key strategic asset for the company, and indeed the country in our view.
“Next up, the company will continue with its drilling campaign specifically targeting the field’s primary oil-bearing Middle Eocene formation to further understand the reservoir dynamics.”
