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. .
