Pakistan wouldnt allow any pipelines on the seabeds of its its extended EEz under the pretext of
1)UNCLOS Article 79 (Subjective freedom under Article 58 refers to Article 87 and Article 87 refers to Article 79)
http://www.un.org/depts/los/convention_agreements/texts/unclos/part6.htm
2.
Subject to its right to take reasonable measures for the exploration of the continental shelf, the exploitation of its natural resources and the prevention,
reduction and control of pollution from pipelines, the coastal State
may not impede the laying or maintenance of such cables or pipelines.
3. The delineation of the course for the laying of such pipelines on the continental shelf is subject to the consent of the coastal State.
4.
Nothing in this Part affects the right of the coastal State to establish conditions for cables or pipelines entering its territory or territorial sea, or its jurisdiction over cables and pipelines constructed or used in connection with the exploration of its continental shelf or exploitation of its resources or the operations of artificial islands, installations and structures under its jurisdiction.
And this...
2) Pakistans official stand on Article 79 as recognized by UN
http://www.un.org/depts/los/LEGISLATIONANDTREATIES/PDFFILES/PAK_1976_Act.pdf
(3)
No person, including a foreign Government, shall, except under, and in accordance with the terms of, any agreement with the Federal Government or a licence or letter of authority granted by the Federal Government, explore the Continental Shelf or exploit is resources or carry out any search or
excavation or conduct any research within the Continental Shelf or drill therein or
construct, maintain or operate therein for any purpose whatsoever any artificial islands, offshore terminal,
installation or other structure or device.
(6) Subject to any measures that may be necessary for protecting the interests of Pakistan, and without prejudice to the provisions of subsection (2), the Federal Government may not impede the laying or maintenance of submarine cables or pipelines on the sea-bed of the Continental Shelf by foreign States:
Provided that the consent of the Federal Government shall be necessary for the delineation of the course for the laying of such cables or pipelines.
So you have to take it around (in red) unless Pakistan agrees .The present Iran-Oman-India pipeline path(in black) shows Indians respected the older EEZ of Pakistan and adhered to UNCLOS rules as detailed above.The official SAGE site also shows a map adhering the EEZ sensitivities of Pakistan.
