Geza Ulole si nlikwambia long term direction ni Gas, hio refinery itakua kusolve short term problem ila ni 10 years vipaumbele vitakua vishabadilika sana

wacha ubishi usio na maana haya mambo ya energy economics ni level nyingine! Refinery ya crude ina benefits nyingi! Huwezi uka-claim eti nchi itakataa refinery! Una-bore wakati mwingine! hata kama tuta-export all that oil! From refinery unapata bitumen, lubricants, petroleum gas pia heavyfuel pia unapata jetfuel etc. n etc.! shughulisha akili kidogo! kwahiyo unataka kudai tukigundua mafuta hatutachimba visima? Huo utafiti wanafanya wembere na mto Eyasi ni wa nn?

TANZANIA: TPDC Launches Phase II of Eyasi–Wembere Oil and Gas Exploration
December 30, 2025
The Tanzania Petroleum Development Corporation (TPDC) has officially launched the second phase of the Eyasi–Wembere oil and gas exploration project, marking a major milestone in the country’s upstream petroleum development efforts. The launch took place at Endeshi Village in Karatu District, Arusha Region.
Phase II of the project focuses on the acquisition of two-dimensional (2D) seismic data around Lake Eyasi, with a total of 914 kilometres of seismic lines planned for survey. Unlike the first phase, which utilised specialised vibroseis vehicles to generate ground vibrations, the current phase will deploy controlled explosive charges placed in the lake to generate sound waves. These waves will be captured using 2D seismic technology to provide more detailed subsurface imaging.
The Petroleum Upstream Regulatory Authority (PURA) is closely overseeing the project to ensure full compliance with the National Energy Policy of 2015 and the Petroleum Act of 2015. PURA is also working alongside TPDC to ensure effective community engagement throughout the exploration process.
According to the project manager, Mr Sindi Maduhu, the contractor, AGS, is currently drilling 15-metre-deep holes where explosives will be safely installed for controlled detonations. To date, approximately 490 kilometres of seismic lines have already been completed, with a target of covering 779 kilometres by April next year.
Once acquired, the seismic data will be processed and interpreted to determine the most suitable location for drilling an exploration well. In preparation for offshore operations within Lake Eyasi, AGS is also assembling boats to support the installation of explosives and data acquisition activities.
The project has placed strong emphasis on local content, with a significant number of residents recruited from surrounding districts, including Karatu, Ngorongoro, Meatu, Kishapu, Igunga, Iramba and Mkalama. Officials indicate that the second seismic phase, which spans 914 kilometres, is being implemented at an estimated cost of TZS 43 billion, with 47 per cent of the work already completed.
The Eyasi–Wembere Basin covers approximately 10,634.9 square kilometres across five regions and is considered a high-potential frontier basin. Geologically, it shares similarities with proven petroleum provinces such as Uganda’s Albertine Graben and Kenya’s Lokichar Basin. Studies conducted since 2015 have confirmed the presence of oil and gas indicators, including oil-bearing rock formations, suggesting strong prospects for commercial discoveries.
The launch of Phase II represents a significant step forward in Tanzania’s oil and gas exploration agenda, with the potential to unlock new energy resources, create employment opportunities for local communities, and strengthen the country’s long-term energy security.
