ge 6 THE BATTALION THURSDAY. APRIL 6, 1978 i&M researcher says: Nitrogen may increase oil yield By TERESA ROACH The injection of nitrogen at high essures is being studied as one issible method of increasing the oil covery in Texas oil fields, said Dr. ml Crawford, assistant director of exas Petroleum Research Commit- e and professor of petroleum en- neering at Texas A&M University. “In a usual oil reservoir one ordi- arily recovers 20 percent of the oil i place when the reservoir has to e abandoned, because it is no mger economical to produce by rimary methods, ’ Crawford said. “By injection of gas or water, one an get a second crop of oil (usually ot quite as big as the first) so that verall we expect to recover one- hird of the oil in place when the eservoir has to be abandoned,” Crawford said. “This is true using the current oil nd gas recovery methods and to- lay’s economics.” “In Texas 150 billion barrels of oil have been discovered since the be ginning of time. Without additional research we expect to recover 50 bil lion barrels of oil. This leaves 100 billion barrels of oil as a challenge to research,” Crawford said. “We have produced approxi mately 40 billion barrels of oil in Texas. This leaves 10 billion barrels of oil yet to be produced with cur rent concepts,” he said. The Texas Petroleum Research Committee has been doing research to determine the feasibility of in creasing oil recovery by injecting ni trogen at high pressures, Crawford said. Nitrogen is injected using either electrical motors to drive nitrogen compressors or gas engines to drive reciprocating nitrogen compressors, he said. Laboratory researchers have ob tained oil recoveries greater than 90 percent of the oil originally in place. but the recovery in an oil field would only be half of this due to ir regularities in the rock, Crawford said. Nitrogen is obtained by cooling air to minus 300 degrees and separating the nitrogen and oxygen by distillation, a process that drives gas or vapor from liquids or solids by heating and condensing to liquid products. Crawford said that this process results in a pure, dry, non- corrosive nitrogen that can be in jected into a petroleum reservoir. “Pure nitrogen can be used in oil reservoirs that have light crude oils. That is, that crude oil that pours like water, not that which is thick and pours like honey,” Crawford said. Nitrogen may also be used for pressure maintenance and in con densate reservoirs, he said. Conden- state reservoirs are reservoirs where pressures are lowered to produce liquid. The shortage of natural gas, to gether with high prices, has re quired that suitable substitutes be developed to replace natural gas,” Crawford said. “Nitrogen is readily made from the air,” he said. “It can be used as a substitute for natural gas. “Nitrogen is not quite as good as natural gas, but natural gas is in very short supply and it costs four times as much as nitrogen,” Crawford said. The first plant using pure nitro gen has been in operation for more than a year, he said. A second plant was installed seven months ago. Both plants are located in the For- doche Field in Louisiana. Crawford said additional plants can be expected to begin operation this year. Approximately $25,000 is spent on laboratory research per year and over $1 million is spent on field tests per year, he said. An experiment related to oil recovery of high- pressure nitrogen injections is conducted by Dr. Paul Crawford, assistant director of Texas Petroleum Research Committee and professor of petroleum engineering, Tim Murray and Jim O’Leary, research technolo gists (from left to right).

Effective ’till April 15 the highest injury rates, according to sports health detectives reporting in Pediatrics, journal of the American Academy of Pediatrics. Dr. James G. Garrick and his as sociate, Ralph K. Requa, both with the department of orthopedic surgery at the University of Wash ington, base their report on a two- year study of injuries among partici pants in sports at four high schools in the Seattle area. At least 5.5 million American youths participate in high school athletics. The study showed injuries oc curred in women’s sports at a rate of 22 per 100 participants; among men, at a rate of 39 per 100. “In spite of improvements in safety equipment, training and con ditioning programs, as well as more sophisticated medical surveillance, the number of athletes injured as a result of sports participation con tinues to increase,” Garrick re ported. “Providing routine medical care for 5.5 million teenagers is logisti- cally difficult, and placing these youngsters in a highly competitive active sport environment com pounds the problem. “Obviously there simply are not enough physicians, athletic trainers, nurses or other medically trained individuals to be present at every competitive event in the 33 high school sports to say nothing of the practice sessions. “Just providing physician cover age for more than 5,000 high school football games each fall is an impos sible task.” The information, according to the investigators, can help school offi cials to make decisions regarding insurance coverage and assigning medical or paramedical personnel to athletic events and practice sessions likely to have high injury rates. Four Seattle area high schools with an average enrollment of nearly 1,300 were involved in the study.

Which means there’s far less chance of leakage or bypass. And here’s some thing else you’ll like about Tampax tampons: the price. The economy-size package of 40 costs less —tampon for tampon — than any other brand. So if you want a lot of protection at very little cost, open a package of Tampax tampons.
