Ntorya’s promise and the wells that proved it
If Kiliwani North was Aminex’s proof of concept, the Ruvuma basin was always the real prize. Stretching across southern Tanzania and into Mozambique, this frontier play had the scale to change the company’s future — if it could be unlocked.
The first breakthrough came in 2012 with the drilling of Ntorya-1 (NT-1). The well flowed at around 20 MMcfd of gas, with light condensate. For the first time, Aminex had a discovery of material size — one that could support development rather than just prove hydrocarbons existed.
Five years later, in 2017, the partners drilled Ntorya-2 (NT-2). This wasn’t just a repeat exercise — it was confirmation. NT-2 flowed at rates above 17 MMcfd and extended the known limits of the reservoir, it even brought the excitement of oil shows in the mud cuttings! With two wells delivering strong results, independent assessments began to point to hundreds of billions of cubic feet, and potentially over a trillion cubic feet, of gas in place.
For Aminex, NT-1 and NT-2 were transformational. Together they showed that Ruvuma wasn’t a marginal basin — it was one of East Africa’s most exciting undeveloped gas assets. But success brought a new problem.
Big discoveries demand big money. Building a processing plant, drilling more wells, and laying a pipeline to Madimba would cost hundreds of millions of dollars. For a junior like Aminex, already stretched by years of exploration, that scale of capex was impossible to fund alone.
It left the company at a crossroads: hold onto the prize and risk running out of money, or bring in a heavyweight partner with the resources to carry it forward..
The Ntorya discoveries proved the potential. The next challenge was to secure the funding and expertise to turn them into production.
