Primary producing methods left behind 100 billion barrels. Secon dary and tertiary recovery offer ways of getting more. Two things — economics and time — stand in the way, says Dr. Paul B. Crawford of Texas A&M University. Government-controlled oil prices make producing the oil by secondary and tertiary methods cost more than it brings on the market. A Getty Oil spokesman said thermal oil brings less than $5 a barrel under federally-fixed prices. For compari son, a barrel of foreign oil last fall cost $14. But even if price restrictions are eased on domestic oil in the near future, Crawford adds, enhanced recovery faces the other problem. “If we wait until wells are plugged and abandoned, it’s very unlikely that thes processes will be initiated on a paying basis,” said the assistant director of the Texas Petroleum Re search Committee and a Texas A&M petroleum engineering pro fessor. Crawford has tests in mind for some Texas fields about to he closed in. He has begun studies on adapt ing fireflooding alternated with steam to enhance recovery. Pre viously unproductive separately in shallow Texas fields, the techniques have been applied with success in other U.S. localities. “Fire-flooding pushed oil out of a reservoir like fire in a cigarette pushes out tar,’ Crawford ex plained. He believes a combination of fire and steam should enhance re covery in deeper Texas formations. Once techniques are lab-proven, field tests will require a series of wells in a field in which production has fallen off. In the steam-fire alternated method,” the engineer said, “steam would be injected first to heat up the rock and oil, thinning the oil. Then a burn would be started and manipulated by varying injected air pressure, pushing the thinned oil to producing wells. Cold water would be injected after the burn, since it would become steam on contact with the heated rock. An 80 to 85 percent recovery might be expected due to ir regularities in the oil-bearing rock. Ten to 15 percent of the in-site oil would be burned in fire-flooding. “But the combined technique will also encounter what I call the baseball diamond problem,” Craw ford said, a possible further limit re covery. “Suppose we had injection wells at first, second and third bases and home plate, with the producing well on the pitcher’s mound. How do we get the oil out of left field?” Minimum distances between in jection and recovery wells can be to lerated using enhanced recovery techniques. Enhanced methods costs run high. Besides capital outlay for big air compressors to obtain 1,000 pounds per square inch in deep res ervoirs, companies will pay a double price for injecting steam and fire. “The price of oil produced by this method should not he less than the price the government allows on im ported oil,” Crawford commented. The Oil Producing and Exporting Countries (OPEC) have in the last six months twice boosted prices from $14 a barrel. “Federal pricing policy, in effect. amounts to Congress voting to provide jobs and lower taxes in OPEC countries, instead of provid ing oil, jobs and lower taxes in the United States,” Crawford said. “Free market pricing is required to produce the energy we need to warm our homes, run our busi nesses and provide jobs for Ameri cans.” \&M Univenffi 4 secret eompe . can t be hidde < >n in 1977 and:, ' ■lions relies on Animal clinic begun ifficials from Texas A&M Uni- .. , sitv and the veterinary profes- z tor a weaknesv k .. ., , . a hailed as a major step the tern that mvol , «.• r c-iiir ailed construction ot an $11.5 s r . libn clinical facility during i' ,M0 r i un( l breaking ceremonies Wed- ihe “word" be le. dav. , TT .

Speaking for the profession, William L. “Dub Anderson, im mediate past president of the American Veterinary Medical As sociation, called the facility “vital” for continued preparation of the best professionals. He said Texas A&M’s veterinary program was second-to-none among those he had visited. Dean of VCteririary Medicine George C. Shelton described the occasion as a “red letter day” for which the college had been plan ning for five years. Shelton noted that Texas A&M, the nation’s largest veterinary col lege, trains about 10 percent of America’s practitioners in a facility built for about a fifth the present size. Figures indicate Texas A&M has been operating on the smallest ratio of square feet per student of any veterinary program in the United States. Miller added that the new con struction will complement the cooperative human-veterinary med ical program at Texas A&M, which already includes the Institute of Comparative Medicine adminis tered jointly with Baylor College of Medicine. ■* ni-calyXMrrt.
