ROUND UP

Commercialisation of South Africa’s first onshore Helium and Natural Gas field

On 4 May 2016,The

Linde Group

, gases and

engineering company, itsAfrican subsidiary

African Oxygen

Limited (Afrox) and alterna-

tive energy company

Renergen

Limited,

through its subsidiary

TETRA 4

(Pty) Lim-

ited, signed an historic agreement for the

commercialisation of the Free State Helium

and Natural Gas (NG) field.

The 187 000 hectare Helium/NG field in

Virginia, nearWelkom, has proven reserves

of 25 billion cubic feet of Natural Gas and

Helium and is the first and only onshore

petroleum (and natural gas) right in South

Africa capable of supplying Helium to nu-

merous specialised and industrial markets.

Under the agreement signed, TETRA 4

has contracted the Helium under an offtake

agreement with The Linde Group, via its

Global Helium business, being assigned

distribution rights for substantial reserves

of Helium. JSE listed Afrox, a member of

The Linde Group, will operate the plant and

market the Helium.

“The signing of this agreement marks

an historic moment in bolstering South

Africa’s self-sufficiency in terms of Helium

production,”said Afrox Managing Director,

Schalk Venter.

Relatively scarce on earth

Helium, although the secondmost abundant

gas in the universe, is relatively scarce on

earth and tends to be found trapped with NG

in relatively low concentrations typically up

to 1% by volume of the gas released. The

Free State Helium and NG field, however,

enjoys concentrations of up to 3 - 4% by

volume.

Linde’s high-tech extraction technology

will separate Helium fromNG through a sin-

gle system utilising a patented processing

plant which purifies, compresses, liquefies

and stores the Helium, ready for distribution

to customers. The Helium plant will be de-

signed and delivered by Linde Engineering

and is expected to commence operations

in 2018/19.

The Linde plant reduces the energy need-

ed and cuts CO

2

emissions of traditional

Helium from NG extraction processes and

represents the latest in engineering tech-

nology advances. The plant is of modular

design and will be precision manufactured

in Europe before being shipped to the Free

State for fast and efficient construction.

Commercialisation of Helium

Nick Haines, Head of The Linde Group’s

Global Source Development, Global Helium

& Rare Gases, said: “Linde has worked

diligently to commercialise this

unique Helium resource together

with TETRA4 and looks forward

to receiving Helium upon com-

mencement of plant operations.”

Utilising the latest in land pres-

ervation techniques, TETRA 4 has

drilled wells, thousands of feet

deep to tap the NG source dome,

while ensuring minimal visual

and environmental impact on

the gas field’s landscape. Wells

and well-heads are being interconnected

underground via an intricate network of

pipes.These pipes will feed directly into the

Linde engineered Helium processing plant.

Social regeneration

As part of TETRA 4’s commitment to social

regeneration, the company has created a

number of bursaries for local students in

the Virginia/Welkom area and has refitted

the local Stilte Primary School with class-

rooms, furniture, a solar borehole pump,

and upgraded the children’s play area.

TETRA 4 also plans to supply the local

operations of MegaBus with compressed

natural gas, (CNG) as ‘green’ fuel for its

local bus services.

Renergen Chief Executive Officer, Stefano

Marani, said: “Today is indeed an important

milestone as we embark on the beneficia-

tion of this important Helium deposit for the

benefit of all our stakeholders.”
