The following table presents the changes in EOG's total proved undeveloped reserves during 2016, 2015 and 2014 (in MBoe):
## Table 0 ##
For the twelve-month period ended December 31, 2016, total PUDs increased by 7 MMBoe to 1,053 MMBoe.
EOG added approximately 21 MMBoe of PUDs through drilling activities where the wells were drilled but significant expenditures remained for completion.
Based on the technology employed by EOG to identify and record PUDs (see discussion of technology employed on pages F-35 and F-36 of this Annual Report on Form 10-K), EOG added 117 MMBoe.
The PUD additions were primarily in the Permian Basin and, to a lesser extent, the Rocky Mountain area, and 82% of the additions were crude oil and condensate and NGLs.
During 2016, EOG drilled and transferred 149 MMBoe of PUDs to proved developed reserves at a total capital cost of $1,230 million.
Revisions of PUDs totaled positive 64 MMBoe, primarily due to improved well performance, primarily in the Delaware Basin, and lower production costs, partially offset by the impact of decreases in the average crude oil and natural gas prices used in the December 31, 2016, reserves estimation as compared to the prices used in the prior year estimate.
During 2016, EOG sold 46 MMBoe of PUDs primarily in the Haynesville play.
All PUDs for drilled but uncompleted wells (DUCs) are scheduled for completion within five years of the original reserve booking.
For the twelve-month period ended December 31, 2015, total PUDs decreased by 104 MMBoe to 1,046 MMBoe.
EOG added approximately 52 MMBoe of PUDs through drilling activities where the wells were drilled but significant expenditures remained for completion.
Based on the technology employed by EOG to identify and record PUDs, EOG added 153 MMBoe.
The PUD additions were primarily in the Permian Basin and, to a lesser extent, the Eagle Ford and the Rocky Mountain area, and 80% of the additions were crude oil and condensate and NGLs.
During 2015, EOG drilled and transferred 121 MMBoe of PUDs to proved developed reserves at a total capital cost of $2,349 million.
Revisions of PUDs totaled negative 242 MMBoe, primarily due to decreases in the average crude oil and natural gas prices used in the December 31, 2015, reserves estimation as compared to the prices used in the prior year estimate.
During 2015, EOG did not sell any PUDs and acquired 54 MMBoe of PUDs.
For the twelve-month period ended December 31, 2014, total PUDs increased by 158 MMBoe to 1,149 MMBoe.
EOG added approximately 50 MMBoe of PUDs through drilling activities where the wells were drilled but significant expenditures remained for completion.
Based on the technology employed by EOG to identify and record PUDs, EOG added 354 MMBoe.
The PUD additions were primarily in the Eagle Ford and Permian Basin, and 80% of the additions were crude oil and condensate and NGLs.
During 2014, EOG drilled and transferred 160 MMBoe of PUDs to proved developed reserves at a total capital cost of $2,655 million.
Revisions of PUDs totaled negative 80 MMBoe, primarily due to removal of certain natural gas PUDs.
During 2014, EOG sold 10 MMBoe and acquired 4 MMBoe of PUDs.
Capitalized Costs Relating to Oil and Gas Producing Activities.
The following table sets forth the capitalized costs relating to EOG's crude oil and natural gas producing activities at December 31, 2016 and 2015:

The following table presents the changes in EOG's total proved undeveloped reserves during 2017, 2016 and 2015 (in MBoe):
## Table 2 ##
For the twelve-month period ended December 31, 2017, total PUDs increased by 110 MMBoe to 1,163 MMBoe.
EOG added approximately 38 MMBoe of PUDs through drilling activities where the wells were drilled but significant expenditures remained for completion.
Based on the technology employed by EOG to identify and record PUDs (see discussion of technology employed on pages F-38 and F-39 of this Annual Report on Form 10-K), EOG added 199 MMBoe.
The PUD additions were primarily in the Permian Basin and, to a lesser extent, the Eagle Ford and the Rocky Mountain area, and 74% of the additions were crude oil and condensate and NGLs.
During 2017, EOG drilled and transferred 153 MMBoe of PUDs to proved developed reserves at a total capital cost of $1,440 million.
Revisions of PUDs totaled positive 33 MMBoe, primarily due to updated type curves resulting from improved performance of offsetting wells in the Permian Basin, the impact of increases in the average crude oil and natural gas prices used in the December 31, 2017, reserves estimation as compared to the prices used in the prior year estimate, and lower costs.
During 2017, EOG sold or exchanged 8 MMBoe of PUDs primarily in the Permian Basin.
All PUDs, including drilled but uncompleted wells (DUCs), are scheduled for completion within five years of the original reserve booking.
For the twelve-month period ended December 31, 2016, total PUDs increased by 7 MMBoe to 1,053 MMBoe.

Business Segment Information EOG's operations are all crude oil and natural gas exploration and production related.
The Segment Reporting Topic of the ASC establishes standards for reporting information about operating segments in annual financial statements.
Operating segments are defined as components of an enterprise about which separate financial information is available and evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance.
EOG's chief operating decision-making process is informal and involves the Chairman of the Board and Chief Executive Officer and other key officers.
This group routinely reviews and makes operating decisions related to significant issues associated with each of EOG's major producing areas in the United States, Trinidad, the United Kingdom and China.
For segment reporting purposes, the chief operating decision maker considers the major United States producing areas to be one operating segment.
