HyTerra Ltd has provided an update on the Company’s upcoming flow testing operations at its Project Geneva in Nebraska, USA. HyTerra and its joint venture partner, Natural Hydrogen Energy LLC have agreed on the work program for flow testing of the Hoarty NE3 natural hydrogen exploration well. The purpose of the extended test is to record gas flow data over a period of several months to establish the hydrogen production potential of the well and measure key parameters that include gas composition, pressure and flow rate. The joint venture has engaged with service providers and is making the final selection of bids and mobilisation schedules for commencement in Q1 of 2023.The operation will involve installing an artificial lift system known as an electrical submersible pump. An ESP is a commonly deployed type of downhole pump that will be used to dewater the well and thereby remove the hydrostatic pressure on subsurface gases.It is anticipated this will allow hydrogen enriched gases to flow freely from two prospective zones. These zones are associated with elevated hydrogen concentrations that were detected during drilling and swabbing operations and were further defined by petrophysical analysis that identified increased rock porosity and gas saturation.Well data will be continuously measured at the well site and gas samples will be sent for independent laboratory analysis. These analyses will focus on the concentrations of hydrogen, as well as other commercially significant non-hydrocarbon gases that may coexist in the gas stream. This includes helium, which was observed as having elevated concentrations in previous gas sampling.
