Miscible CO2 continues to eclipse steam injection in Oil & Gas Journal's 2014 EOR/Heavy Oil Survey.
Production from US miscible CO2 floods totals 292,735 b/d vs. 284,725 b/d for steam, according to the survey (Table 1).
The miscible CO2 production rate is 5% below its level of the previous OGJ survey, published in 2012 (OGJ, Apr. 2, 2012, p. 56). Production from this technique, accounts for 38% of US output from EOR.
Production from steam injection has decreased by 6% from 2012.
Miscible CO2 dominates US EOR in project totals at 109 in 2014 (Table 2). The 2012 total in this category was 112.
The number of steam projects remains at 48 in 2014.
Total oil production by EOR in the US is now 778,048, according to OGJ's survey, up 2% from 2012.
Tables A-E show survey results for projects in the US and around the world.
Oil & Gas Journal prepared the EOR/Heavy Oil Survey this year with the help of Advanced Resources International Inc., Arlington, Va., which supplemented survey results with information about specific projects and contributed the accompanying article on the outlook for CO2-EOR. Steve Melzer of Melzer Consulting, Midland, provided valuable assistance.
