Sir,
I am sure you are aware of Pakistan's perpetual revenue shortage, current account deficit and the resulting perpetual shortage of funds in general & FE in particular. With due respect, don't you think that the above question is rather naive?
According to the info available with me and onshore well costs between $5 to $7-million in the USA. You also need an oil rig which could set you back up to $20-million. Even renting a decent oil rig could cost you around $20K per day. In Pakistan, it would probably cost more.
On the other hand, an Offshore Oil rig is extremely expensive. A deep sea oil rig could cost anywhere between $200-million to $600-milion? Even renting a floating deep-sea drilling rig/ship is very expensive at around $200K per day. Including the operating expenses, a deep sea oil drilling operation could easily set you back about $400K per day. Hence it cost at least $75-million to drill Kekra-1
Understand OGDC already has two or three oil rigs (guesstimate only). That is why one sees OGDC & PPL drilling a lot more onshore wells and finding a couple of small oil/gas reservoirs ever so often. However, no Pakistani company has the experience nor is in possession of offshore oil rigs. Hence we need to wait for the foreign companies who are ready to sink a lot of money in the hope of finding oil in Pakistani waters.
IMHO it is therefore incorrect to compare Pakistan with other countries. Pakistan simply does not have money for offshore drilling.
I hope the above clarifies why Pakistan has thus far only drilled 18-offshore wells.
P.S. I apologize if my remarks hurt your feelings. I meant no disrespect, but it irks me when intelligent members ask questions with self-evident answers.
