Recent sub-surface studies of the Gummy Gas Field have resulted in a significant upgrade of its gas and liquids resource potential. Previous interpretations had ascribed little resource potential to the field. Shell drilled Gummy-1 in 1990, a Golden Beach (GB) Subgroup gas/liquids discovery in the eastern Gippsland Basin. The GB Subgroup was previo...

Using borehole image logs and core to characterise fracture style and occurrence.

This report presents the results of core description performed using cores recovered from Hess Australia’s Snapshot-1 well, from WA-474-P in the Northern Carnarvon Basin, offshore Western Australia.

Prior to 2012, petroleum wells in the eastern portion of the Nappamerri Trough (Cooper Basin) were scarce with only a handful of wells drilled in an area of approximately 5,000 square kilometers. Recently, the Nappamerri Trough has become the focus for an extensive shale gas and basin centered gas exploration campaign. Sparse regional 2D seismic li...

Vintage dipmeter data and its usage in a modern sense

Vintage dipmeters and their data

Minor amounts of authigenic pyrite are common throughout the Middle Jurassic Brent Group, often being well developed within the delta‐plain fades of the Ness Formation. Petrographic analyses of pyrite samples from the Lyell and Murchison fields reveal two stages of pyrite authigenesis, both of which occurred during an early stage of burial. The fir...

The theoretical analysis of pressure response associated with Wireline Formation Test (WFT) data was first introduced in 1962 by Moran and Finklea1 but was generally not widely used due to its radius of investigation being very small comparable to that of conventional drill stem testing, and due to gauge resolution limit2. Analytical techniques usi...

The sedimentology of the Mungaroo Formation

Characterisation of carbonate lithofacies from borehole image logs

This paper is part of the special publication No.159, Borehole imaging: applications and case histories (eds: M.A. Lovell, G. Williamson, and P.K. Harvey). Borehole image logs provide high-resolution directional data sets, in addition to a wealth of information concerning sedimentary fabric and texture. The data derived from these images are typica...

Use of borehole image logs for the evaluation of fractures

In recent years much emphasis has been placed upon unravelling the sequence evolution of coastal and marine deposystems whereas continental depositional environments have received little attention. Sequence stratigraphic models developed for marine and coastal environments have delineated the regional controls which influence the deposition and pre...

The Jerudong Formation (early Tortonian) cropping out at Punyit Beach (Negara Brunei Darussalam) comprises a heterolithic succession of deltaic strata. Probepermeameter data have been used to evaluate the spatial nature of permeability heterogeneity within shoreface, lagoon and distributary channel environments. Strata at outcrop comprise the same...

This paper is part of the special publication Developments in petrophysics (eds M.A. Lovell and P.K. Harvey). A steady-state probe permeameter is designed that is robust, insensitive to moisture and can be operated using a low-pressure gas source. Consequently, substantial reduction in weight and bulk are possible and a truly one-man-operable, ligh...

The Lower Permian Penrith Sandstone in the Vale of Eden represents the deposits of fossil aeolian dunes, which are well cemented by syntaxial quartz overgrowths in the northern part of the outcrop. The overgrowths possess a complex internal growth fabric as revealed by scanning electron microscopy-cathodoluminescence. Fluid inclusions are common in...

Sandstones deposited in deep marine environments form important hydrocarbon reservoirs in many basins throughout the world. However, despite the plethora of outcrop studies and the development of numerous submarine fan models and classification schemes, very few applied studies at a reservoir scale have been published. This publication has arisen f...

Analysis of high density (5 cm sample spacing) probe permeameter data has been used to evaluate some of the basic controls on permeability heterogeneity in the Miller Field. Probe permeameter data generally show good correspondence with conventional core-plug permeability data gathered at 25 cm spacings, but record a higher frequency of permeabilit...

Up to four calcite-cemented horizons (doggers) form impermeable barriers to fluid flow within the Middle Jurassic Rannoch Formation and are correlatable across the Murchison Field. Calcite precipitated during early diagenesis, within high porosity/permeability sandstones at the top of coarsening (shoaling) upward shoreface cycles. Calcite δ¹³C and...

Sedimentological research has traditionally produced geological models primarily relevant to hydrocarbon exploration, focusing predominantly on location and external geometry of sediment bodies and underplaying the importance of the internal reservoir framework. This failure inhibits the application of new technologies to improve recovery efficienc...

A combination of sedimentary dip, structural dip and borehole orientation resulted in a core recovered from the Auk Field being cut sub-parallel to aeolian slipface deposits. Individual 2 inch (5 cm) thick grainflow deposits may be followed for up to 16 ft (4.88 m) along core. A conventional core-plug permeability data-set indicated the importance...

The Rotliegend Lower Leman Sandstone Formation has been studied near the northern limit of its development in Ravenspurn North to determine the influence of structure, sedimentology and diagenesis on reservoir quality. The Lower Leman Sandstone in this area is about 300 ft thick and comprises six depositional cycles which reflect alternating period...

The Kurnia-1 well was drilled as the first test of the Kujung Formation in the South Madura exploration block on Madura Island in the East Java Basin. The well was drilled to test a large anticlinal structure mapped on 2D seismic data. The well encountered very strong mudlog gas shows that persisted throughout the Kujung section. An open-hole produ...
