Spectrometer donated to The University of Tulsa Geosciences program by Samson Resources

Samson Resources donates XRF spectrometer to geosciences

The University of Tulsa Department of Geosciences has received an equipment donation from Samson Resources for graduate and undergraduate research. Samson representatives delivered the XL3t950 GOLDD+ portable X-ray fluorescence spectrometer on Feb. 21. The device measures the elemental concentrations of solid materials and powders, including all types of rock.

Valued at $40,000, the XRF will be used to measure shale compositions for unconventional reservoirs of petroleum, drill core compositions in the lab and rock bodies and layers in the field. The instrument also will be used on soils in the field to detect pollutants and help locate metal deposits.

Applied Associate Professor Winton Cornell (left) and McMan Professor of Geosciences Peter Michael will use the spectrometer in TU’s lab facilities.

“We very much appreciate the donation,” said department chairman and McMan Professor of Geosciences Peter Michael. “We are hopeful some of our final chemical analyses of rocks can be done with the XRF. It will allow us to train students to do their own analyses.”

If the XRF proves to be sensitive and accurate enough, Michael said it will save the department money by avoiding the cost of sending rock samples to commercial labs off campus for further chemical analysis.

The Samson donation is TU’s second XRF; Gilcrease Museum and the Department of Anthropology own a similar device for research purposes. Samson geologist Stephen Secrest said working with TU to donate the XRF has opened up an avenue of cooperation for future projects in the program.
