Optimization of Oil Field Production Under Gas Coning Conditions Using the Optimal Closed-Loop Estimator

Optimization of Oil Field Production under Gas Coning Conditions Using the Optimal Closed-Loop Estimator

In an oil field that has reached its maximum gas handling capacity, and where wells are producing under gas coning conditions such that the gas-oil ratio (GOR) depends on the wells production rate, oil production is maximized if the marginal GOR (mGOR) is equal for all wells. The GOR and the mGOR are not readily available measurements, but they can be predicted using detailed reservoir models. ...

SPE 143520 Modeling, Simulation, and Optimal Control of Oil Production under Gas Coning Conditions

Gas coning is a tendency of the gas to impel the oil downward in an inverse cone contour toward the well perforations. Once the gas reaches the well, gas production will dominate the well flow and the oil production will hence significantly decrease. From an economical and operational standpoint this condition is undesirable since the gas price is much lower than the oil price, and the gas hand...

Optimal Development Planning of Offshore Oil and Gas Field Infrastructure under Complex Fiscal Rules

The optimal development planning of offshore oil and gas fields has received significant attention in recent years. In this paper, we present an efficient investment and operational planning model for this problem which is fairly generic, and is extended to include fiscal considerations. With the objective of maximizing total NPV for long-term planning horizon, the proposed non-convex multiperi...

Closed-Loop Supply Chain Stability under Different Production-Inventory Policies

Product returns from market to the manufacturer can happen because of the motivation to capture the value content of the product after use or the obligation from legislation and the environmental concerns. A manufacturing system capable of integrating both the manufacturing and remanufacturing activities can help the recovery of value content in the products after the end of product’s use life....
