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. .

( 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 2019s 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 255000 ( 51000 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 159000 gross ( 32000 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. .
