Higher crude oil prices have spurred enhanced oil recovery action in Twofreds field in west Texas. Houston Natural Gas Corporation's (HNG) Fossil Fuels Corporation has a fieldwide waterflood and miscible CO/sub 2/ enhanced recovery program under way. HNG is alternating water injection with injection of CO/sub 2/ and inert gases to boost oil yield from ca. 4392 productive acres. Cumulative production since tertiary recovery began is 1.4 million bbl. HNG is injecting an average of 8 to 10 MMCFD of CO/sub 2/. CO/sub 2/ source is Oasis Pipeline Company's Mi Vida treating plant near Pecos, Texas. The CO/sub 2/ is extracted from gas produced by wells that tap the deep Ordovician Ellenburger in the area.
