Georgia is an amazing geological structure, he explains to Proactive, but unlike more uniform structures it requires careful drilling and geoscience.
The recent 16aZ sidetrack proved the concept, he explains.
Block will now shoot new 3D seismic to make sure it hits the right spots and gets a similar result when it drills in future.
In fracture plays such as West Rustavi the problem is formation water ingress, he says.
Avoiding the bigger fractures which attract water and hooking ino the smaller ones is key.
The next well, 38Z, will be similar to 16aZ but going in the opposite direction, while Well 30 and Well 3 will also test the deeper Eocene levels for gas.
“[It is] all about fractures and optimising the horizontal well so that it penetrates the right sort at the right length.”
