RE: Flow rate16 Apr 2026 10:42
@magpie1862 the below is from RNS april 2025. However, as said porosity is likely much better than Sproule estimate. Plus perforation. Plus acidization
= much better flow rates
Gas composition confirms helium
Mosman's technical team has reviewed hard copies of data received from the former operator, Seeley Oil Company, and
found reports of gas sample analyses dated December 30 1993, following an open hole drill stem test ("DST") performed
at the Sagebrush-1 well in December 1993. This report states the DST gas samples contained 2.76% helium, circa 20%
methane, and significant quantities of nitrogen (35%) and carbon dioxide (40%), alongside traces of other heavier
hydrocarbons (3%).
Commercial flow rates
The DST flowed gas to surface in the range 152-163 mcfd.
These flow rates, combined with the attractive gas composition, indicate that this well could be a commercial producer of
helium with the additional financial benefit of methane production that may be useful for generating power for the
separation of helium, for compression and/or for added value with sales of natural gas to power stations.
