Oilfield operators have always looked for ways of reducing the costs of oil and gas development projects and especially when investment costs were critical to project economics. Tubingless completions have evolved over the last 30 years in North America to fill the need for reduced investment costs particularly in the case of fields with either limited reserves or limited profitability.Tubingless completions basically utilise small diameter tubulars to function as both production casing and flowstring. The tubulars are cemented in the borehole, not to be removed or recovered until the field is depleted and/or the well abandoned. The technique is limited in application to those fields with no corrosion or wax or hydrate problems and with a limited requirement for reservoir stimulation and workovers. The greater the number of operations performed within the tubingless well bore the greater the risk of losing the well.The main benefits of tubingless completions are as follows:Reduction in development well completion costs.Marginally productive hydrocarbon zones can be completed and tested.Completion of individual gas zones of multi-pay wells within their own permanently segregated flowstrings at much lower capital and operating costs.The experience this far with Kincora gas field development wells indicates the tubingless completion method to be completely feasible for gas wells drilled in the Surat Basin and possibly in other areas of Australia.

Energy Information

Despite unconventional targets being recognised across many Australian sedimentary basins and the Energy Information Administration (EIA), estimating a technically recoverable shale gas resource of >400 tcf in Australia, there have been no definitive tests that prove that any of these potential plays will flow gas at commercial rates. There has, however, been a number of technical successes reported from both shale gas and basin centred gas plays. This extended abstract reviews select plays from both frontier and mature basins across Australia, including basins where Origin is actively exploring or appraising unconventional gas plays—the Perth, Cooper and Beetaloo basins. The technical challenges vary from play to play, but many of the above ground challenges are not play specific. To advance the industry, Origin and other companies will have to demonstrate a resource sufficiency that is economic in a high cost environment like Australia, while maintaining a positive relationship with communities. In its expansion into the NT, through its interest in the Beetaloo Basin, Origin has the benefit of 20 years' experience dealing with complex stakeholders and environmental challenges through its CSG development projects in Queensland. This experience is invaluable in advising best practices for engaging with local communities, landholders, traditional owners, and regulatory and government bodies. For the technically-minded asset development teams charged with exploring unconventional plays in frontier basins, where stakeholders are unfamiliar with oil and gas development projects, new skills are required that need deep organisational support.

Geopolitical Risks

The article is devoted to the consideration of geopolitical challenges for the analysis of geoenvironmental risks (GERs) in the hydrocarbon development of the Arctic territory. Geopolitical risks (GPRs), like GERs, can be transformed into opposite external environment factors of oil and gas industry facilities in the form of additional opportunities or threats, which the authors identify in detail for each type of risk. This is necessary for further development of methodological base of expert methods for GER management in the context of the implementational proposed two-stage model of the GER analysis taking to account GPR for the improvement of effectiveness making decisions to ensure optimal operation of the facility oil and gas industry and minimize the impact on the environment in the geopolitical conditions of the Arctic.The authors declare no conflict of interest
