Big Star Continues To Increase Helium Footprint

Special Report: Big Star has picked up more helium leases, one of which includes an elevated helium sample taken during its earlier regional gas survey.

Big Star Energy has leased a further 1640 net acres of helium prospective land in Colorado, taking its total foot print up to 92,443 gross (39,811 net) acres. “We are rapidly extending and consolidating our leasing coverage of the Enterprise prospect where we are targeting our exploration efforts on the Lyons Sandstone which is pervasive in the region and has previously produced helium in Las Animas County,” managing director Joanne Kendrick said. “We are also pleased to have acquired a lease in our Prometheus prospect which includes an elevated helium sample taken during our regional gas survey. We will continue to consolidate our leasing position at Enterprise and our other prospects.” The Company’s large acreage position is located in Las Animas County Colorado. The county has a history of helium production dating back to the 1920’s when the Model Dome helium field was produced for a short period. This field, at 8%, is one of the top-4 highest helium concentrations to have been produced in the USA. It was subsequently acquired by the US Government and held as part of its strategic helium reserve. Helium is in short supply despite being a critical component in modern technology applications such as for magnetic resonance imaging machines and in nuclear medicine. This has resulted in helium prices rising over the past decade to over 100 times the price of natural gas in the US. And with the US federal reserve set to shut down completely by 2021, new sources of helium will have little difficulty finding eager buyers.

Helium in the Williston Basin?

The Williston Basin is known for its oil and gas reserves. But helium? “We know that there’s helium there in the Basin,” said state geologist Ed Murphy. “That’s from what little records we have on that.” Murphy said the Canadians have much more information on this. “They’ve got economic quantities of helium, produced in the 1960s and 1970s,” Murphy said. “They’re back in now with a big drilling program.” Murphy said that program is centered on southern Saskatchewan. “And we’re saying, ‘Let’s take a look at North Dakota,'” Murphy said. The Survey has put out a report, to guide industry, if it was to come to North Dakota. “We said, ‘Here’s the area that looks the most promising,'” Murphy said. Murphy said helium was reported to be in short supply, because of Middle East embargoes. He said the helium market is very volatile — but it could be an opportunity for some companies.

Influence Of Low-vacuum Helium Cold Plasma Pre-treatment On The Rooting And Root Growth Of Zoysiagrass (Zoysia Willd.) Stolon Cuttings

The influence of low-vacuum helium cold plasma treatment on the rooting percentage, root growth and physiochemical properties of zoysiagrass stolon cuttings was studied. Zoysiagrass stolon cuttings were pre-treated with 0, 100, 200, 300 and 400 watts (W) of cold plasma for 15 seconds. The cold plasma positively stimulated rooting and improved the root growth of the zoysiagrass stolon cuttings, and the 300 W treatment produced the best effect. The rooting percentage and root growth parameters, including the root length, total root surface area, total root volume, average root diameter, and root dry weight, significantly improved in response to the cold plasma treatment. In addition, the water uptake and relative conductivity of the stolon cuttings increased significantly in response to the cold plasma treatment. The results revealed that cold plasma-stimulated rooting and root growth appear to be a consequence of the improvement in permeability and water absorbing capacity of zoysiagrass stolon cuttings. The results of the present study will provide inspiration and support for the application of cold plasma in the vegetative propagation of plants.

Helium Depth Profile Measurements Within Tungsten Coatings By Using Glow Discharge Optical Emission Spectrometry (GDOES)

In the present paper results concerning the implementation of the Glow Discharge Optical Emission Spectrometry (GDOES) for measure the He depth profile within W coatings are given. The He emission line situated at 587.5 nm was used in this respect. W coating containing He up 10 at.% and with thickness of 5 μm have been obtained by Combined Magnetron Sputtering and Ion Implantation (CMSII) method. The coatings structure and morphology was investigated using Scanning Electron Microscopy (SEM) measurements. The He retention within the coatings was evaluated by using Thermal Desorption Spectroscopy (TDS). Time-of-Flight Elastic Recoil Detection Analysis (TOF ERDA) measurements has been used to determine chemical composition of the coatings. Results of TOF-ERDA measurements results were used to calibrate the GDOES equipment. Using these data the GDOES depth profiles of the He within W coatings have been obtained.

Testing Diffusion of Cosmic Rays In The Heliosphere With The Proton-to-helium Ratio Data From AMS

After six years of continuous observations in space, the Alpha Magnetic Spectrometer experiment has released new data on the temporal evolution of the proton and helium fluxes in cosmic rays. These data revealed that the ratio between proton and helium fluxes at the same value of rigidity \R=p/Z (momentum/charge ratio) is not constant at \R≲,3,GV. In particular, the ratio is found to decrease steadily during the descending phase of Solar Cycle 24 toward the next minimum. We show that such a behavior is a remarkable signature of the
β×λ(\R) dependence in the diffusion of cosmic rays in heliosphere, where β is their adimensional speed and λ(\R) is their mean free path, a function of rigidity for all nuclei. This dependence is responsible for distinctive charge/mass dependent effects in the time-dependent modulation of low-rigidity particles.
