Core to Santos GLNG's long-term business is the ongoing development of natural gas wells in Queensland's Surat and Bowen Basins. The construction of a well site begins with a well pad, where the drilling rig sits and drills a well to extract gas. Collected gas is then piped to compressor stations for treatment. This work is handled by the Santos GLNG Upstream division.
On earlier projects, Santos GLNG engaged with its EPC contractors to design its well pads individually and stick-build them on-site. The Santos GLNG Upstream team identified an opportunity to minimize the time and costs spent on individual well pad design and initiated a project to develop the capability to replicate a standard design then reproduce all the required deliverables.
As a first step, a large EPC was engaged to work on the project. The EPC was already using a range of Intergraph® design tools, including Intergraph Smart™ 3D, SmartPlant® Instrumentation for instrument datasheets and loops, and SmartPlant P&ID for piping and instrumentation diagram design. Additionally, Santos is a long-time user of Intergraph solutions – for example, the internal myPlant operating platform is built on SmartPlant Enterprise for Owner Operators. Santos GLNG Upstream information manager, Shaun Barclay, deployed these tools in-house so that EPCs working on GLNG in the future could utilize them in the Santos environment via a Citrix connection, minimizing the requirements at handover and ultimately saving time and money.
Once deployed, the Santos GLNG Information Management team used the systems to create an as-built of the asset, make changes to existing facilities, and standardize well pad design for replication. The team was enabled to use the specifications and corporate standards within the software, enabling the quick and easy design of fit-for-purpose skid packages to suit the coal seam gas industry in the current market.
"After we’ve created a standardized design, we use Intergraph's design tools to recreate and replicate the design so that we have all the deliverables – for procurement, construction, commissioning, and operations – that are required for the maintenance of the facility for the next 25 years," said Barclay.
