Development in the Surat

surat-aus-mapQGC has recently embarked on a $1.7 billion development of gas tenements in Queensland that will see the construction of 300-400 wells in the Surat Basin. The works are part of the company’s continuous development to sustain gas supply to both domestic customers and the QCLNG plant near Gladstone, and are set to provide a boost to drilling contractors in the region.

QGC has appointed Leighton Contractors as the main works contractor and they will progress development and construction immediately.

According to Jason Linaker, Managing Director at kwik-ZIP Centralisers, the large number of wells and their relatively remote location will be a great challenge for drilling contractors.

“Working at sites such as the Surat, you need to be using trusted products with low inventory and transport costs. Unnecessary packaging can cause costs to skyrocket and can ultimately slow down the project.”

Sourcing products that can be used across the whole site is also something to consider.

“With 300 wells to be drilled, time savings can be made across the entire development if the same drilling products and associated equipment are used,” says Mr Linaker.

“This removes any confusion for the workers, and cuts down on training time for each product. It also provides continuity across the project, with one point of contact if any technical advice is needed.”

QCLNG since first production

Since first LNG production in December 2014, the QCLNG plant has delivered 62 cargos.

Managing Director of QGC, Tony Nunan, has said that the development was an important investment in the future of QGC’s operations and built on the success of the world-first production of liquefied natural gas from coal seams in the past year.

“This is a vote of confidence in the secure, long-term future of Queensland’s natural gas industry, which will employ Queenslanders for many years to come,” said Mr Nunan.

“The development will help to sustain the benefits of our investment in local communities and the state, including up to 1,600 construction jobs and business opportunities during the two-year project.”

Sourcing the best equipment

According to Mr Linaker, this sort of development is a real positive for the community and the state at large, so ensuring that the project is completed successfully with long-lasting results is important.

“kwik-ZIP centralizers for CSG wells are a hard-wearing and corrosive-free casing centralizer option, suited to remote worksites such as these in the Surat,” says Mr Linaker.

“The design and packaging of kwik-ZIP centralizers is segmented, making them suitable for a very large range of pipe diameters and easy to transport across long distances at a low cost.

“As well as this, each system is flexible enough to allow for bow heights for different casing/borehole combinations, making them user friendly across the board. This means that on-site personnel need only be trained in the one centralizer system, instead of a different centralizer designs and brands for each well of a differing size.”
