NG Energy International Corp. has completed the tie-in of the Aruchara-4 ST-1 well at the Maria Conchita block in Colombia, reaching an initial output of 15.9 million cubic feet per day (MMcf/d) with wellhead pressure at 1,434 psi. The production is now connected to the Central Processing Facility (CPF), and could increase to 19.8 MMcf/d following a minor modification of the compressor lines, while maintaining wellhead pressure above 650 psi.
Projected payback in under three months
The company stated that gas from the Aruchara-4 ST-1 well will be sold at prices exceeding $11.00 per million British thermal units (MMBtu), with an expected return on investment in less than three months. Additional zones identified during drilling (H3, H4, and H5) will be tested after the recompletion of the Aruchara-3 well is finalised. This well had previously produced up to 12 MMcf/d before a mechanical obstruction became lodged in the wellbore.
Recompletion work on the Aruchara-3 well is expected to take two weeks and forms part of a broader infrastructure optimisation plan at Maria Conchita. These developments are anticipated to bring the block’s total processing and transport capacity to 30 MMcf/d by the end of November, in parallel with the recompletion work.
Treatment capacity expanded at Sinú-9
At Sinú-9, NG Energy and its joint venture partners have installed additional dew point handling equipment at CPF-1, increasing total block processing capacity to 60 MMcf/d (40 MMcf/d via Surenergy’s CPF-1 and 20 MMcf/d via the INFRAES plant), with potential for further expansion. Current steady-state production at Sinú-9 stands at 24 MMcf/d, and the initial pipeline loop is expected to boost transport capacity to 40–45 MMcf/d by year-end.
Drilling of the first well in a planned six-well campaign, Hechicero-1X, is set to begin in the last week of November. These developments are intended to strengthen Sinú-9’s role as a key contributor to domestic gas supply in Colombia.
Targeting 55 MMcf/d by end of 2025
The company reports having reached a combined gross production of 40 MMcf/d, accounting for approximately 4% of Colombia’s domestic gas market. NG Energy expects this to rise to 50–55 MMcf/d by year-end, driven by ongoing work at both fields.
The closing of the transaction with French firm Etablissements Maurel & Prom S.A. remains subject to regulatory approval by the Colombian Agencia Nacional de Hidrocarburos (ANH), as well as standard closing conditions, with approval anticipated in Q4 2025.
