D3 Energy (ASX:D3E) has confirmed helium concentrations of 5.2% in gas samples from its Nooitgedacht Project in South Africa.
The company successfully completed remedial cementing activities at the NGT245 E well, isolating deeper water zones and re-establishing gas flow. The restored flow enabled collection of gas samples for compositional analysis.
Analysis confirmed helium concentration of 5.2% and methane of 49.7% from NGT245 E.
The company notes the ‘anomalously low’ methane result is being retested but says the results demonstrate the scale of the helium system across its Free State acreage position.
The Nooitgedacht project sits within the 100%-owned ER315 permit in the Free State, approximately 40km from D3 Energy’s production right application area.
Managing Director David Casey says the result further demonstrates the scale of the helium system across the company’s South African portfolio.
“Another world class helium concentration of 5.2% in what is our first drilling operation at Nooitgedacht, some 40km from our Production Right application area, is a great result,” Casey notes.
D3 Energy will undertake further analysis of camera and log data with additional remedial work expected ahead of production testing.
Remediation work will resume at NGT245 D following a stabilisation period after initial cementing operations.
The company says drilling program data, together with high-resolution seismic data acquired at Nooitgedacht, will enable it to refine structural interpretation of the project area.
D3 Energy holds approximately 190,140 hectares across the Free State Province, comprising multiple exploration rights and technical cooperation permits.
The company’s flagship ER315 permit has delivered independently verified helium concentrations of up to 8% and is subject to a production right application currently under assessment by South Africa’s Petroleum Agency.
D3 Energy is an Australian helium and natural gas explorer advancing projects across South Africa and South Australia.
