Too early to say anything.
As someone who worked on new explorations (DST), this is toooooo early to have an accurate estimate of the formation.
I am not a reservoir engineer, someone who is is better positioned to expand more on this, but after this initial flow, the flow is tested at various choke sizes to get an estimate of the the flow volumes.
Later on, once the well is completed, this well would be again tested with wireline and slickline tools (BHP/T gauges) to further study it's profile.
Moreover, this is more important, further appraisal wells will be drilled according to the drilling plan in the formation, to get an idea about the size of the reservoir and it's characteristics. DST's will be done, and so will other tests.
1 well takes more or less 2-3 months to drill considering all goes to plan, so give or take 3-4 more well, we are looking at a year before we have a good enough idea about the reservoir. A year or two more before we actually start producing from it.
Let's hold on to our pants.
I have seen production engineers and company man get all excited and call the head office jab adhi choke par well flow kar raha tha and the flare was like a matchstick!
But still, this is encouraging news on the face of it, and Mari would be very relieved with this news kyunkay in kay apnay halat pichlay kuch arsay say zyada achay nhn ja rahay thay.
