What we do
Shell is an integrated energy company that aims to meet the world’s growing demand for energy in ways that are economically, environmentally and socially responsible.
Shell Exploration and Production Tanzania Limited
When Royal Dutch Shell Plc acquired BG Group and assumed the ownership of BG’s assets in February 2016, the opportunity arose for Shell to monetize the resources discovered offshore Tanzania. Shell’s presence in Tanzania began in the late 1930’s with minimal exploration activities. Shell came back to Tanzania after a BG Shell combination in 2016 and became operator of two offshore blocks, Block 1 and Block 4, together with its partners Ophir Energy and Pavilion Energy.
After extensive exploration activities in the two blocks, significant deep-water gas discoveries, sufficient to support a multi-train land based LNG project, have been made. 18 wells were drilled, 16 Trillion Cubic Feet (TCF) of natural gas discovered and over $2 billion worth of investment spent.
Shell Exploration and Production Tanzania Limited with partners is currently working with the Government of Tanzania on cost competitive development options for the Tanzania Gas and LNG project and establishment of the commercial framework for the project. The project is currently focused on selecting the optimal integrated upstream and liquefied natural gas project. The Tanzania LNG project is at a stage where detailed planning and multiple agreements need to be agreed between the International Gas companies (IOCs) and the Government.
Shell is a global group of energy and petrochemical companies.
Our operations are divided into four businesses: Upstream, Integrated Gas and New Energies, Downstream, and Projects & Technology.
In Upstream we focus on exploration for new liquids and natural gas reserves and on developing major new projects where our technology and know-how add value for resource holders.
In Integrated Gas and New Energies, we focus on liquefying natural gas (LNG) and converting gas to liquids (GTL) so that it can be safely stored and shipped to markets around the world. The New Energies business has been established to explore and invest in new low-carbon opportunities.
In Downstream, we focus on turning crude oil into a range of refined products, which are moved and marketed around the world for domestic, industrial and transport use. In addition, we produce and sell petrochemicals for industrial use worldwide. Shell’s oil sands mining activities in North America are also part of the Downstream organisation.
Our Projects & Technology business is responsible for delivering new development projects and the research and development that leads to innovative and low-cost investments for the future.

Exploration of natural gas off the coast of Southern Tanzania.
Shell TVC - English Transcript
Since 2010 we’ve been exploring for natural gas up to 100 kilometres off the coast of Southern Tanzania, operating in waters around two kilometres deep, one of the most modern vessels of its type equipped with the latest in satellites and drilling technology has been drilling gas bearing [?] rocks up to four kilometres beneath the sea floor.
Animated footage of drillship at sea pans to various views of ship. A helicopter landing on ship. View of ship showing depths of drilling underwater. Diagram shows depth of 2Km water and lower 4Km rock.
At these extreme depths the gas is trapped in reservoirs, some as large as 180 square kilometres. Wells drilled into the rocks releases the gas giving it a path to flow.
Shot changes to show drilling equipment beneath the surface of the water and pans down to show entire depth. Shot changes to long view of drillship on surface of sea.
We’ve made multiple discoveries, extracting the gas and bringing it to shore is technically challenging, complex and costly, involving multi-billion-dollar investments. The plan is for gas to flow up through well heads and then along hundreds of kilometres of sub-sea pipelines on the ocean floor up the continental shelf, then on to shore.
Various shots of machinery and pipelines showing how the gas is brought to shore.
Once on land a portion of the new gas reserves will go towards meeting demand for energy in Tanzania. Where existing and potentially new gas appliance power generation is available the gas could be used to cool and light homes, cook meals and to power vehicles, industries and factories.
Animated sequence showing path of the gas to industrial areas and homes. Homes are shown with the lights being turned on, and food being cooked on a gas hob.
At the onshore gas processing plant the gas will be cleaned and cooled in huge refrigeration units known as liquification trains at a temperature of minus 160 degrees Celsius the gas becomes liquid, commonly known as liquified natural gas or LNG.
Views of many refrigeration units panning out to shot from above.
The LNG process substantially reduces the volume of the gas, similar to shrinking a football to the size of a marble. This makes the gas easier to transport safely to customers around the world in specially designed ships. The gas is then shipped and sold abroad with revenue coming back to Tanzania.
Various views of the specially designed ships that transport the gas around the world.
This new high technology industry offers Tanzania the opportunity to develop its natural gas reserves, diversifying and expanding the country’s economy, attracting support, businesses and creating jobs. An LNG export project could significantly boost government revenues providing funds with the potential to transform Tanzania’s social and economic development.
Map of Tanzania appears onscreen panning in to show Mtwara, Lindi on the coastline of the Indian Ocean. The shots pans up to show position of Dar es Salaam, Tanga, Dodoma, Mwanza, Bukoba, Kigoma, Mbeya, Songea. View of the maps pans out to show the positions of these locations in Tanzania.
We’ve made a good start, but much work is still to be done. Early engineering and studies on potential environmental, social and economic impacts have been completed. A decision to proceed will come after terms and conditions have been mutually agreed between the government of Tanzania and the investors.
The view of the maps pans out show the map of Tanzania in full.
Following a decision to go ahead after a construction period of around five years production will commence establishing Tanzania as a leader in the emerging East African natural gas province.
