TX 75083-3836, U.S.A., fax 01-972-952-9435.Abstract PRISM (Plan Resource Implement Schedule Manage) is a project management toolkit developed to facilitate the field operations of the Petroleum Engineering department of Santos Ltd. for onshore Australia. It is believed that PRISM is unique in its functions when compared to other off-the-shelf project management applications. Currently PRISM enables the management of approximately 1200 projects (including in excess of 250 drill, complete and connect projects) being implemented by five major and four minor field resource types, comprising up to 20 major and 40 minor individual field resource packages that are deployed daily. These represent approximately A$450 million of activity planned for implementation in 2006.A major part of the PRISM rollout process has been to gain user acceptance and encourage users to use the toolkit, both as a source of information on projects and to keep details updated. This paper also looks at the project implementation and rollout process, including barriers and lessons learned.

Santos’ Roma field, located in the Surat Basin, has been producing coal seam gas (CSG) since 1988; however, development drilling did not commence until 2011. Since this time, well design has evolved to maximise access to coals and operability for artificial lift systems. Concurrently, performance has dramatically improved through scale of sanctioned work programs and revised contracting strategies, enabling continuous and sustainable time and cost reductions. This paper reviews Santos’ development drilling activity in the Roma CSG field since 2011, highlighting critical events and step changes. The following aspects are addressed: • Evolution of well design: A series of well designs have been trialled, ranging from deviated to vertical, fracture stimulated to open-hole slotted liner well types. Collaboration with both Reservoir Engineering and Production Operations have been critical in arriving at a fit-for-purpose design. • Effect of the industry downturn: The industry downturn spanning 2014–2016 presented an opportunity to reset and rationalise execution approach. • Operating and contracting model: The updated model focused on utilising a consistent, fit-for-purpose rig fleet and service companies, supported by lean office and field based operations teams. • Benefits of large scale, continuous work programs: The scale and continuity of operations are key to achieving continuous and sustainable time and cost reductions. • Opportunities: Future opportunities have been identified for ongoing optimisation in a changing market.
