"If each party can sell its own share of the oil separately then who pays the operating costs?"
I'd have thought it was obvious..
The Operator, HHDL, bills the co-venturers for their share of the total costs (after the carry expires). This will be a budgeted number adjusted monthly to reflect actuals. From an accounting view this is separate from the income stream.
The Operator sells the oil and credits the co-venturers with their share of the cash in and makes a payment to them (normally monthly).
IF the co-venturer think they can get a better price themselves (or maybe they need the oil as a feed stock for their own refinery) they just tell the Operator and make their own arrangements. A separate tanker arrives when their share is big enough to justify one, gets topped up and drives off to whoever and wherever they've sold it to. The cash goes directly from their buyer into their account . The Operator adds whatever extra costs (minimal TBH) to the monthly OPEX bill. The Operator sells the remainder as above but doesn't credit any payments to the people who took physically took delivery.
Offshore, where the numbers are a lot bigger, there are often quite complex arrangements as to when you can call for your share to avoid people NOT taking their share when the price is falling and everyone wanting a delivery when the price is rising.
