Unconventional hydrocarbons are increasingly contributing to the worlds oil and gas production. Three unconventional resource types contribute to global gas production: Tight gas in low permeability sandstones or carbonates Coal…
North American shale gas and Australian CBM represent the two most significant unconventional resources discovered to date. Australian CBM and US shale gas currently supply 2030% of their domestic markets. Both resources had long…
In Australia, the potential for CBM production is well established in a series of adjacent basins, 2,000 km in length, inland from the east coast. The Permian Bowen and Gunnedah basins and the Jurassic Surat Basin all contain areas…
The outlook for the Cooper Basin is excellent thanks to infill drilling of conventional fields, tight gas and shale gas. Significant thicknesses of gas saturated rocks are present where these reservoirs can be exploited, and the…
The initial exploration phase comprises drilling core holes to collect reservoir information for evaluation purposes. And unlike conventional plays, this often requires 10s of core holes. Within a typical core hole anywhere up to 500+…
Sweet spots usually occur in unconventional plays. These are areas where the permeability and, possibly, gas content or reservoir thickness are enhanced relative to other areas in the play fairway. The causes are typically:…
Once a high graded location has been identified, an initial pilot program will be drilled to demonstrate hydrocarbon flow and potential commercialisation. The pilot program is unique to the reservoir, ranging from a single multi stage…
The next step in cost reduction comes from execution of repeated drilling trials. Experience and efficiencies bring down drilling time and refinement of completion types results in increases in unit production. As an example,…
In summary, unconventionals will play an increasing role in both gas and oil production. Unconventional gas has a future outside North America CBM production is building and shale gas exploration has commenced in at least three…
