proved undeveloped reserves decreased 45% ( 45 % ) from year-end 2014 to year-end 2015 , and the year-end 2015 balance represents 17% ( 17 % ) of total proved reserves .drilling and development activities increased devon 2019s proved undeveloped reserves 24 mmboe and resulted in the conversion of 182 mmboe , or 26% ( 26 % ) , of the 2014 proved undeveloped reserves to proved developed reserves .costs incurred to develop and convert devon 2019s proved undeveloped reserves were approximately $ 2.2 billion for 2015 .additionally , revisions other than price decreased devon 2019s proved undeveloped reserves 120 mmboe primarily due to evaluations of certain properties in the u.s .and canada .the largest revisions , which reduced reserves by 80 mmboe , relate to evaluations of jackfish bitumen reserves .of the 40 mmboe revisions recorded for u.s .properties , a reduction of approximately 27 mmboe represents reserves that devon now does not expect to develop in the next five years , including 20 mmboe attributable to the eagle ford .a significant amount of devon 2019s proved undeveloped reserves at the end of 2015 related to its jackfish operations .at december 31 , 2015 and 2014 , devon 2019s jackfish proved undeveloped reserves were 301 mmboe and 384 mmboe , respectively .development schedules for the jackfish reserves are primarily controlled by the need to keep the processing plants at their 35 mbbl daily facility capacity .processing plant capacity is controlled by factors such as total steam processing capacity and steam-oil ratios .furthermore , development of these projects involves the up-front construction of steam injection/distribution and bitumen processing facilities .due to the large up-front capital investments and large reserves required to provide economic returns , the project conditions meet the specific circumstances requiring a period greater than 5 years for conversion to developed reserves .as a result , these reserves are classified as proved undeveloped for more than five years .currently , the development schedule for these reserves extends through to 2030 .at the end of 2015 , approximately 184 mmboe of proved undeveloped reserves at jackfish have remained undeveloped for five years or more since the initial booking .no other projects have proved undeveloped reserves that have remained undeveloped more than five years from the initial booking of the reserves .furthermore , approximately 180 mmboe of proved undeveloped reserves at jackfish will require in excess of five years , from the date of this filing , to develop .price revisions 2015 2013 reserves decreased 302 mmboe primarily due to lower commodity prices across all products .the lower bitumen price increased canadian reserves due to the decline in royalties , which increases devon 2019s after- royalty volumes .2014 2013 reserves increased 9 mmboe primarily due to higher gas prices in the barnett shale and the anadarko basin , partially offset by higher bitumen prices , which result in lower after-royalty volumes , in canada. .
