Helix Exploration, the helium exploration and development company with near-term production assets within the Montana Helium Fairway, is pleased to announce that it will commence re-entry and acidisation of Clink #1, and has commissioned Petroleum Consultants LLC to oversee contractor services.
Highlights:
· Acidisation of Clink #1 well to commence mid-February 2025
· Re-entry and acidisation to take circa. 10 days from commencement
· Acidisation will test capacity to stimulate flow from the Charles Formation
· Contractor services to be overseen by Petroleum Consultants LLC
· Additional production wells being surveyed at Rudyard for drilling in Q2 2025
Bo Sears, CEO of Helix Exploration, commented:
“While our recent focus has been on the rapid commercialisation of the Rudyard Project, we remain committed to the significant potential of Ingomar Dome, and the promising helium and hydrogen indications seen at Clink #1. Following the successful closure of our non-discounted placing to raise £5 million, we are now fully funded to bring Rudyard into production in the coming months, with excess capital to fund growth projects. This enables us to commence acidisation at Clink #1, a highly cost-effective method to test the production potential of the Charles Formation by removing near-wellbore damage caused by heavy muds. We are looking forward to updating the market in due course.”
Background
Operations are due to commence shortly on the acidisation of the Clink #1 well to stimulate and flow test the Charles Formation. The Charles Formation, a limestone reservoir, is expected to respond well to stimulation with hydrochloric acid. The Company is confident in the reservoir properties of the Charles Formation, based on drill cuttings that demonstrated visible porosity, gas shows including helium, and pulsed neutron wire-line logs indicating reservoir quality.
Further confidence is derived from the interpretation of pressure build-up data from our initial flow test attempt in November 2024. Following the initial swabbing of the Charles perforation interval, a decision was made to pump into the perforations to confirm the presence of an open flow path, ensuring no plugged tubing and correct packer depth. The pump-in test indicated a pressure break at approximately 1,800 psi, equivalent to around 0.8 psi/ft, consistent with the normal fracture gradient. The significant difference in pressure build-up before and after the pump-in test suggests that the induced minor fracture created a flow path to virgin reservoir. However, this was insufficient for sustained flow as the fracture healed quickly. The subsequent acid treatment is expected to remove drilling fluid permeability blockages near the wellbore and establish open flow paths.
Acidisation of the Charles Formation is expected to commence in mid-February 2025, depending on local weather conditions, with flow rate results available approximately ten days from the commencement of operations. Results of the flow testing will be announced alongside assay results of any gas recovered from the operation.
Rudyard
Helix management have recently conducted a site visit to Darwin #1 wellhead and proposed initial plant location. The visit allowed the Company to advance discussions with Hill Country Electric regarding power provision, as well as inspecting pipeline routes from the wellhead to the plant-site. Helix management have also met with various landowners and service providers local to the Rudyard area who could expediate development into production.
The Company has commenced surveying the location of the next production wells at Rudyard. New wells, along with the Darwin #1 well drilled in November 2024, will increase supply of raw helium gas to the processing plant. Drilling is targeted to commence in early Q2 2025 when warmer temperatures reduce drilling costs.
