Now, that the fever of #Turkey's gas finding has cooled off (or not?), time for a (long) THREAD on challenges and implications #OOTT #ONGT
The gas is in ULTRA-deep waters: mark this term, it bears important outcomes

and the gas reserves were hit 1400 meters further, at nearly 3500 m water depth.
Total depth of drillings is expected to reach 4525 m where two more layers of gas are likely to be found (accord' to Fatih Donmez)

In the same vein-and very important when it comes Turkey's energy security-is whether future gas reserves will be found in the block area, which totals 7000 square kilometers-Turkish authorities are rather positive about that 6/

2. When the gas will reach the consumers
Given the complexity entailed by ultradeep waters projects, and the *scale of investment*(see below), the 2023 timeline put forward by the Turkish authorities might be overly optimistic

In this regard, it will be intriguing to see what would be the trade-offs from the Russian side (especially when it comes the gas price), and if their scope would encompass solely the gas, or it would touch also 15/
