As attention to unconventional oil and gas resources increases, historical oil and gas flows in shale reservoirs across the world are being given renewed attention. Such is the case of the shaly and carbonate deposits of the McArthur and Nathan groups in the Northern Territory. The Batten Trough is a Proterozoic depocenter with potential for a shale gas play in the Barney Creek Shale and potential for conventional gas accumulations in the underlying Coxco Dolomite. This Barney Creek Shale gas play is evidenced by a number of mineral exploration drill holes that encountered live oil and gas shows within the McArthur Group. The most prominent was a mineral exploration hole drilled at the Glyde River prospect by Amoco in 1979. This well reportedly flowed gas and condensates at 140 psi for six months before it was sealed at the surface, which certainly shows permeability values greater than micro-darcies reported for many North American shale plays; thus, an exploration program of this prospective area has been planned by Armour Energy in EP 171 on several targets adjacent to the Emu Fault Zone near both Glyde and Caranbirini, along with other anticline related targets adjacent to the Abner Range. This extended abstract details how the targets were identified, the plan for data acquisition (e.g. seismic, drilling, logging and testing), and the proposed completion strategy to test this highly prospective target.

Affected by the constant development of global economy and the imbalance in distribution of conventional oil and gas, oil and gas resources can no longer meet the demand in many countries. Development of unconventional oil and gas has begun to take shape. Shale gas and tight oil become the focus of global attention. Unconventional oil and gas resources are relatively abundant in China. Preliminary results have been achieved in the development of shale gas. Tight oil has been developed in small scale, and the main technologies are maturing gradually. Yet we face many challenges. Low in work degree, resources remain uncertain. Environmental capacity is limited, and large scale batch jobs will confront with difficulties.

In early 2012, Armour Energy set out to evaluate the Middle-Proterozoic formations in the Batten Trough, McArthur Basin, NT. The Batten Trough holds a massive potential shale gas play in the Barney Creek Formation, and recent gas discoveries in the overlying Lynott and Reward formations, and underlying Coxco Dolomite. The Lawn Supersequence, Isa Superbasin, Queensland, is another Middle-Proterozoic shale gas play with overlying and underlying conventional and unconventional oil and gas accumulations. Exploratory drilling between the 1980s and 1990s showed gas and oil shows across the Isa Superbasin, Queensland. Egilabria–1, ATP 1087, exhibited 390 gas units while drilling with mud, highlighting the prospectivity of this area. In both areas, the Barney Creek and Lawn Hill formations are proven source rocks and are significantly older than North American shale reservoirs. In 2012, an innovative exploration program was designed and implemented in the NT to maximise the capture of drilling data while integrating data from previous mineral and petroleum exploration programs. This resulted in gas discoveries at Cow Lagoon–1, EP 176, and in the Glyde–1 and Glyde–1 ST lateral wells in the Glyde Sub-basin in EP171. In both cases, air drilling was instrumental in aiding drilling penetration rates, gauging gas influx while drilling, and allowing geologists to rapidly obtain and assess drill cuttings. The authors first discuss the details of the formation evaluation methods used in Armour’s successful 2012 program and how these methods are extended to Armour’s 2013 program in the Isa Superbasin, northern Queensland. Next, an outline of the strategy for further delineation of the Batten Trough is provided. Finally, the authors summarise the exciting potential of the Lawn Supersequence in Queensland.

With the continuous improvement of the understanding of the geological law and continuous innovation of unconventional oil and gas exploration and mining technology, China has made great breakthroughs in newly-added geological reserves of unconventional oil and gas resources, such as shale gas, coalbed methane, etc. But for many reasons, attention has not been paid to oil and gas resources (petroleum, natural gas, coalbed methane, shale gas), and regional remote sensing monitoring research has not been carried out. Based on high-resolution remote sensing data of the year 2018 and human-computer interactive interpretation technique, this paper built remote sensing interpretation signs of oil and gas mines, carried out exploration of remote sensing monitoring methods for oil and gas mines, completed remote sensing monitoring over development status of oil and gas mines in Ordos Basin, and proved feasibility of remote sensing monitoring method.

Chapter 2 details the differences and similarities among twenty-first-century petroleum resources and distinguishes conventional from unconventional resources. The chapter argues that, while these definitions are muddled, there is value to understanding and parsing unconventional oil and gas. Numerous different oil and gas resources are then surveyed, including shale gas, ultradeep gas, Arctic gas, tight gas, coalbed methane, biogas, acid gas, geopressurized gas, methane hydrates, condensates, light tight oil, extra-heavy oil, ultradeep oil, Arctic oil, depleted oil, kerogen, biofuels, gas-to-liquids, and coal-to-liquids. Estimates are provided of cumulative industry greenhouse gas emissions for conventional versus unconventional oil and gas resources. The chapter concludes with a discussion of hydrogen—the ultimate unconventional resource—and its production pathways.
