The North Perth Basin (NPB) offers one of the most attractive areas for Hot Sedimentary Aquifer (HSA) geothermal projects in Australia. Key geological ingredients for a working geothermal system include a heat source and a heat trap in the form of thermally insulating rocks such as coals or low thermal conductivity shales with underlying naturally...

The technical evaluation of the NPB has identified a number of attractive geothermal target areas, with permeability associated with open natural fractures providing the most promising potential reservoir. The challenge is to devise a method that identifies areas with open fractures and then to apply a work flow that can be used to understand, in d...

The article deals with the application of modern innovative technologies of horizontal drilling and interpretation of 3D seismic data to improve the efficiency of development of unconventional oil and gas resources in fractured carbonate reservoirs of Austin Chalk and Buda formation on Pearsall and Giddings fields in the United States. This new int...

This paper presents innovative techniques & workflows in structural volume interpretation that have been developed to reliably visualize faults and fractures at extremely high resolution from 3-D seismic data, and to subsequently integrate these results with other seismic, well and mine data to derive fully calibrated and deterministic fault/fractu...

Novel techniques and workflows in automated fault extraction have been developed to visualise faults at extremely high resolution from 3-D seismic data, and to subsequently evaluate how these faults can impact resource activities (drilling, mining), resource recoveries (e.g. oil & gas, coal) and the safety of operations (e.g. gas kicks, outbursts)....

This paper reviews the means by which geological uncertainty has been addressed in a complex marginal field development. The Gannet C field development carries a significant element of risk resulting from a challenging drilling environment and large geological uncertainty due to poor structural definition on seismic. By creating extreme high- and l...

Fault and fracture networks can have significant effects on drilling, mining and the safety of resource operations, and can also significantly impact reserve recovery & productivity. Due to this, various automatic fault extraction techniques have been developed for structural volume interpretation purposes in recent years. This paper presents innov...
