KU energy center gets $1.7 million award
Federal grant aimed at project on raising oil well efficiency
The KU Energy Resource Center has been awarded $1.7 million by the U.S. Department of Energy for an oil-recovery project.

tions nationally that received money for oil recovery.
The resource center is channeling the money to three KU groups: the KU Tertiary Oil Recovery Project, the KU Department of Geology and the State of Kansas Geological Survey. The resource center is one of 13 organiza-
Engineers and geologists will be testing new methods of oil recovery that would increase the oil recovery of such wells, benefiting companies by increasing the number of barrels of oil using natural resources, Green said.
Don Green, co-director of the Tertiary Oil Recovery Project, said that U.S. companies were having problems obtaining oil from older wells. Some of the wells are producing three to five barrels of oil a day, which barely accounts for the operating costs of a well. Often these wells are abandoned.
One of the techniques that will be tested is water flooding, he said. In this process, water that has been
"These techniques are not widely used, at least by small companies," Green said. "They don't have the money for laboratories, or often even an engineer, and so their level of technology is not as sophisticated."
thickened from added polymers is flushed into the well to push oil over to another well so it can be more easily obtained.
The three departments learned last week that they received the federal financing, which must be matched by oil investors. They submitted a proposal on the studies in January to the Department of Energy.
Lymn Watney, associate scientist of the Kansas Geological Survey, said University geologists would study the underground layout of the earth. Often the complex layout of a reservoir makes it impossible to direct the oil because the zones where the wells are drilled are not connected.
The KU workers will do field work at the Cherokee sandstone reservoir in
Eastern Kansas and at the Morrow sandstone reservoir in Western Kansas.
Watney said the money would accelerate the project and encourage companies to become involved. The project should begin in six months.
"This is a critical time because companies are going out of business," Watney said. "The price of oil is not real high and there is a lot of oil on the market now. We are trying to help increase their efficiency so they can stay in business and cut some of their costs."
Use of mammograms increasing, survey shows
The Associated Press
BOSTON — The use of mammograms has increased dramatically during the past decade, and now at least three-quarters of all older U.S. women have had the X-rays to check for breast cancer, a researcher said yesterday.
A federal survey shows that the use of the screening test is becoming more common among all levels of society, although they still are used most frequently by women who are white, highly educated and financially well-off.
"These data present a dramatic picture of increasing use of mammography over the past decade," said Robert
Smith, an epidemiologist at the U.S. Centers for Disease Control in Atlanta.
Smith presented the latest CDC data at the 25th National Conference on Breast Cancer.
Breast cancer is the leading cancer killer of U.S. women. The American Cancer Society estimates that one in nine will get the disease.
The CDC's Behavioral Risk Factor Surveillance System surveys health
The society and 11 other health organizations recommend that women have mammograms annually beginning at age 50. They should have their first mammogram by age 40 and have one every year or two from ages 40 to 50.
habits in 17 states. The latest data for 1990 show that 75 percent of all women older than age 40 have had at least one mammogram.
Smith said the same survey in 1986, found that just 54 percent had a mammogram. This rose to 65 percent in 1988 and 71 percent in 1989.
Among other findings:
Of those who said they had at least one mammogram, 60 percent of the women said they had received it during their pregnancy and 40 percent received it one to two years ago.
Women ages 50 to 64 were most likely to have had recurrent mamao
Among ages 40 to 49, the frequency of mammograms appears to be declin-
inɡ sliɡhtlv
After such rapid growth, the increase is slowing, and Smith said it may be difficult to persuade the remaining women to seek mammograms.
"The progress made during this short time is truly remarkable," he said. "Further increases may require needed and allogether different effort."
Lawrence Bassett of the Iris Cantor Center for Breast Imaging in Los Angeles said one way to increase the success of their persuade doctors to recommend them.

He said the primary reason for women not getting mammograms was lack of referral by a physician.
