In the ordinary course of business, based on our evaluations of certain geologic trends and prospective economics, we have allowed certain lease acreage to expire and may allow additional acreage to expire in the future.
If production is not established or we take no other action to extend the terms of the leases, licenses, or concessions, undeveloped acreage listed in the table below will expire over the next three years.
We plan to continue the terms of many of these licenses and concession areas or retain leases through operational or administrative actions.
For leases expiring in 2014 that we do not intend to extend or retain, unproved property impairments were recorded in 2013.
## Table 0 ##
(a) An exploratory well is planned on this acreage in 2014.
Oil Sands Mining Segment We hold a 20 percent non-operated interest in the AOSP, an oil sands mining and upgrading joint venture located in Alberta, Canada.
The joint venture produces bitumen from oil sands deposits in the Athabasca region utilizing mining techniques and upgrades the bitumen to synthetic crude oils and vacuum gas oil.
The AOSP’s mining and extraction assets are located near Fort McMurray, Alberta and include the Muskeg River and the Jackpine mines.
Gross design capacity of the combined mines is 255,000 (51,000 net to our interest) barrels of bitumen per day.
The AOSP operations use established processes to mine oil sands deposits from an open-pit mine, extract the bitumen and upgrade it into synthetic crude oils.
Ore is mined using traditional truck and shovel mining techniques.
The mined ore passes through primary crushers to reduce the ore chunks in size and is then sent to rotary breakers where the ore chunks are further reduced to smaller particles.
The particles are combined with hot water to create slurry.
The slurry moves through the extraction process where it separates into sand, clay and bitumen-rich froth.
A solvent is added to the bitumen froth to separate out the remaining solids, water and heavy asphaltenes.
The solvent washes the sand and produces clean bitumen that is required for the upgrader to run efficiently.
The process yields a mixture of solvent and bitumen which is then transported from the mine to the Scotford upgrader via the approximately 300-mile Corridor Pipeline.
The AOSP's Scotford upgrader is at Fort Saskatchewan, northeast of Edmonton, Alberta.
The bitumen is upgraded at Scotford using both hydrotreating and hydroconversion processes to remove sulfur and break the heavy bitumen molecules into lighter products.
Blendstocks acquired from outside sources are utilized in the production of our saleable products.
The upgrader produces synthetic crude oils and vacuum gas oil.
The vacuum gas oil is sold to an affiliate of the operator under a long-term contract at market-related prices, and the other products are sold in the marketplace.
As of December 31, 2013, we own or have rights to participate in developed and undeveloped leases totaling approximately 159,000 gross (32,000 net) acres.
The underlying developed leases are held for the duration of the project, with royalties payable to the province of Alberta.
Synthetic crude oil sales volumes for 2013 were 48 mbbld and net-of-royalty production was 42 mbbld.
In December 2013, a Jackpine mine expansion project received conditional approval from the Canadian government.
The project includes additional mining areas, associated processing facilities and infrastructure.
The government conditions relate to wildlife, the environment and aboriginal health issues.
We will begin evaluating the potential expansion project and government conditions after current debottlenecking activities are complete and reliability improves.
The governments of Alberta and Canada have agreed to partially fund Quest CCS for 865 million Canadian dollars.
In the third quarter of 2012, the Energy and Resources Conservation Board ("ERCB"), Alberta's primary energy regulator at that time, conditionally approved the project and the AOSP partners approved proceeding to construct and operate Quest CCS.
Government funding has commenced and will continue to be paid as milestones are achieved during the development, construction and operating phases.
Failure of the AOSP to meet certain timing, performance and operating objectives may result in repaying some of the government funding.
Construction and commissioning of Quest CCS is expected to be completed by late 2015.
In May 2013, we announced that we terminated our discussions with respect to a potential sale of a portion of our 20 percent outside-operated interest in the AOSP.
Average Production Cost per Unit(a)
## Table 1 ##
(a) Production, severance and property taxes are excluded from the production costs used in this calculation.
See Item 8.
Financial Statements and Supplementary Data – Supplementary Information on Oil and Gas Producing Activities - Results of Operations for Oil and Gas Production Activities for more information regarding production cost.
(b) Production costs in 2011 include a $64 million water abatement accrual.
(c) Production operations ceased in Libya in February 2011, resuming in 2012, but ceased again in the third quarter of 2013.
Fixed costs continue to be incurred in these periods of downtime.
Marketing and Midstream Our operating segments include activities related to the marketing and transportation of substantially all of our liquid hydrocarbon, synthetic crude oil and natural gas production.
These activities include the transportation of production to market centers, the sale of commodities to third parties and the storage of production.
We balance our various sales, storage and transportation positions in order to aggregate volumes to satisfy transportation commitments and to achieve flexibility within product types and delivery points.
Such activities can include the purchase of commodities from third parties for resale.
As discussed previously, we currently own and operate gathering systems and other midstream assets in some of our production areas.
We continue to evaluate midstream infrastructure investments in connection with our development plans.
Delivery Commitments We have committed to deliver quantities of crude oil and synthetic crude oil to customers under a variety of contracts.
As of December 31, 2013, those contracts for fixed and determinable quantities were at variable, market-based pricing and related primarily to Eagle Ford and Bakken liquid hydrocarbon production and OSM synthetic crude oil production.
A minimum of 54 mbbld of Eagle Ford liquid hydrocarbon production is to be delivered through mid-2017 under two contracts.
Under a 6-year contract ending May 2016, 15 mbbld of Bakken liquid hydrocarbon production is to be delivered.
Under a 3-year contract expected to commence mid-2014, 14 mbbld of synthetic crude oil production is to be delivered.
Our current production rates and proved reserves are sufficient to meet these commitments.
The Eagle Ford and OSM contracts also provide the options of delivering third-party volumes or paying a monetary shortfall penalty if production is inadequate.
The Bakken contract carries no penalty for shortfalls.
Competition and Market Conditions Strong competition exists in all sectors of the oil and gas industry and, in particular, in the exploration for and development of new reserves.
We compete with major integrated and independent oil and gas companies, as well as national oil companies, for the acquisition of oil and natural gas leases and other properties.
Based upon statistics compiled in the "2013 Global Upstream Performance Review" published by IHS Herold Inc. , we rank ninth among U. S. -based petroleum companies on the basis of 2012 worldwide liquid hydrocarbon and natural gas production.
See Item 1A.
Risk Factors for discussion of specific areas in which we compete and related risks.
We also compete with other producers of synthetic and conventional crude oil for the sale of our synthetic crude oil to refineries primarily in North America.
Additional synthetic crude oil projects are being contemplated by various competitors and, if undertaken and completed, these projects may result in a significant increase in the supply of synthetic crude oil to the market.
Since not all refineries are able to process or refine synthetic crude oil in significant volumes, there can be no assurance that sufficient market demand will exist at all times to absorb our share of the synthetic crude oil production from the AOSP at economically viable prices.
Our operating results are affected by price changes for liquid hydrocarbons, synthetic crude oil and natural gas, as well as changes in competitive conditions in the markets we serve.
Generally, results from oil and gas production and OSM operations benefit from higher crude oil prices.
Market conditions in the oil and gas industry are cyclical and subject to global economic and political events and new and changing governmental regulations.

MARATHON OIL CORPORATION Notes to Consolidated Financial Statements 94 Other – Other investments are composed of an investment in an unallocated annuity contract, an investment contract with an international insurance carrier, and investments in two limited liability companies (“LLCs") with no public market.
The LLCs were formed to acquire timberland in the northwest and other properties.
The investment in an unallocated annuity contract is valued using a market approach based on the experience of the assets held in an insurer’s general account.
The majority of the general account is invested in a well-diversified portfolio of high-quality fixed income securities, primarily consisting of investmentgrade bonds.
Investment income is allocated among pension plans participating in the general account based on the investment year method.
Under this method, a record of the book value of assets held is maintained in subdivisions according to the calendar year in which the funds are invested.
The earnings rate for each of these calendar year subdivisions varies from year to year, reflecting the actual earnings on the assets attributed to that year.
Due to the lack of transparency in the use of investment year subdivisions, this asset is considered Level 3.
The insurance carrier contract is funded by premiums paid annually by the participating plans and the funds are invested by the insurance carrier in portfolios with different risk profiles (low, medium, high) that can be elected by clients.
The majority of the underlying investments consists of a well-diversified mix of non-U.
S.  publicly traded equity securities valued at the closing price reported in an active market and fixed income securities valued using calculated yield curves.
This asset is considered Level 2.
The values of the LLCs are determined using a cost approach based on historical cost less depletion for timber previously harvested.
These assets are considered Level 3.
The following tables present the fair values of our defined benefit pension plans’ assets, by level within the fair value hierarchy, as of December 31, 2013 and 2012.
