Introduction

The Oil and Gas Concession located 30kms West of Dar es Salaam in Tanzania, with an area of more than 15,000 sq. km.

In 2007,Dodsal Hydrocarbons and Power (Tanzania), a wholly-owned subsidiary of Indian-owned Dubai-headquartered Dodsal Resources, signed a PSA with Tanzania’s Ministry of Energy and Minerals and Tanzania Petroleum Development Corporation (TPDC) for oil and gas exploration on the RUVU Block.

Previous Seismic Data Processing investigative explorations indicated the presence of hydrocarbons, with re-interpretation conducted at leading technology centers in Canada, USA, Italy, Germany and UK.Dodsal completed technical evaluation of 3,546 LKM Legacy seismic data & 2 Nos. Legacy Wells.

based on these positive results, Dodsal conducted 1,421 LKM of new 2D seismic data, carried out satellite imagery studies and collected 900 geochemical soil samples to establish presence of working petroleum system in the block.

In Feb,2016,Dodsal Resources has discovered natural gas in the Ruvu basin estimated to be 2.17 trillion cubic feet.The firm that signed the Production Sharing Agreement with the Government of Tanzania on October 23, 2007 is said to have discovered the gas in July 2015 but was restricted from making the announcement due to the 2015 Petroleum Act requirements.

In Apri,2016,Dodsal Resources has said it will to invest another US$300 million in Tanzania over the next 24 months to support its exploration and production activities, including implementation of an Early Production System to bring Gas to the market.This will be the single largest investment by the company that has to date invested US$200 million.The company that has so far made the largest onshore gas discovery in Tanzania’s Mambakofi and Mtini region adds that it is carrying on with studies to establish the prospective gas resources at the third well at Mbuyu in the western side of the block, which is estimated to contain upto 5.9 TCF of gas in a large gas column.According to Dodsal based on the current market prices, the gas resources so far discovered is valued at US$8 billion to a potential upside of US$11 billion.

To date three wells have been drilled by the company at Mbuyu, Mtini and Mambokofi all in the coast region.Dodsal drilled 3 Nos. Exploration Wells (Year 2015) and well samples were analyzed by leading international Labs / Agencies (Viz. Core Labs, RPS Energy, CGG, Lomond Associates etc.) to establish presence of working petroleum system in the block.
Reports of above studies confirmed presence of significant hydrocarbon resources, with estimates varying between 5.5 to 7.5 TCF (Trillion Cubic Feet), which makes Ruvu block a single mega on-shore block in Tanzania.Quality of Gas is mainly Methane, with little impurities i.e. no treatment facilities are required. 

Dodsal is preparing to commence drilling exploration, Appraisal wells along with testing and flaring activities in onshore Ruvu Block and had tendered for a partner to provide technical and consultancy services for carrying out and issuing an Environmental Impact Assessment(EIA) Report.
