Thank you for asking this question. In fact, this 10 years is contextual. Contextual in the sense that if you are in deep water offshore exploration—to commence the exploration and then to bring oil or gas to the surface—that is a 10-year context. For onshore, particularly if you discover something, it could be as low as—from day starting—maximum 3 years. But the global trend now, if you see, most of the oil and gas now is being found in the last decade or so. The new discoveries are in deep or ultra-deep water. Deep water—Guyana, for example, Exxon explored for so many years, now it is almost going to hit 1 million barrel production. And why I said this for deep water and ultra-deep water—because you start the process by taking a license, then you have to do seismic, then you have to process it, then interpret it, because it's very hard, large data. And then choose a location, make a choice about a location to drill and see whether your prognosis is right or wrong. So that drilling itself—planning it, signing a contract, and then drilling and finally discovering oil—that process itself, come whatever you do, it takes around 4 years. Then after discovery, you will appraise it—how much is the oil, whether it's economic, not economic—that also takes around a year or so. Then you have to source, you have to do subsea equipment. That project typically, I don't think anybody has done in less than four years. And then if you have gas, then you have another challenge—converting into, if you are close to shore, fine; if you are not close, then you have to convert into LNG to ship it. So nowadays, if you see all the last four years, the numbers which have come—either from Brazil or Guyana—the big numbers, these are all ultra-deep water. In our context also, for our country, we believe now that earlier roughly 3.36 million square km of sedimentary basin in our country—1.2 was blocked, never explored, which has potential, what we call sedimentary basins. Those blocks the government released very recently, and now we expect a lot from there. But most of it, we also believe, will be deep water, ultra-deep water. So in that context, I said we need to compress the time—compress the time of exploring, seismic, explore the time of—you know, now for example—we know for sure that we'll keep doing exploration in deep water for the next 5 years, then we should contract a vessel on a long-term basis, and whoever is exploring there, he can use the same vessel. So then you can save all those times, plus you can compress the time of data processing and interpretation. Similarly, development. So this is one side where we said that in our country also, if we believe now that large potential is left in deep or ultra-deep water—that was the context in which I said 10 years. Otherwise, if you find something onshore, onshore is a game of—like today also, Gujarat, if we keep drilling, we keep discovering, we keep producing. But these quantities just go in making up for the depleted, declining production. So when you notice, almost from the onshore area, we've been producing 6 million ton a year of oil—we are producing 6 million ton a year for the last 10 years—because what we do is, in our parlance, what we call normal decline of reservoir is a standard phenomenon—6 to 7%—you lose production every year from the existing reservoirs. So you keep discovering new reservoirs, adjacent area or nearby areas, and you keep compensating for it. But exploration—if something big, like something big we found in Rajasthan onshore, that was decades back, and then after that, something big in the country—if I remember correctly—it is Krishna Godavari. The rest are small pools which are just going to make up for the continued production. So it was contextual. I wanted to summarize that it should not be said that it takes 10 years in all circumstances. Like for the Middle East, it may be 2 years, because Middle East—all the reservoirs so far, big ones, are still onshore. So therefore, we have to see in that context.
