Gulf Keystone CEO: Iraq’s Hamrin field holds about 7 billion barrels of oil in place

The gap between 7 billion barrels in place and a 10-15% recovery estimate is the real story here: Hamrin is a large but technically demanding resource, and the disclosed range is wide enough to leave the commercial case unresolved. For a company of Gulf Keystone's scale, a field of this size would be transformational, but the numbers are an in-house estimate rather than an independently audited reserve booking, so they carry limited weight until verified. Whether the recoverable range narrows and how the field is developed — and by whom — is the open question.
