     A seismic study was conducted to re-interpret the Qasab and Jawan Oil fields in northwestern Iraq, south of the city of Mosul, by reprocessing many seismic sections of a number of field surveys by using the Petrel software. Two reflectors, represented by the Hartha formation, deposited during the Cretan age, and the Euphrates formation, formed during the Tertiary age, were delineated to stabilize the structural picture of these fields. The stratigraphic study showed that the Qasab and Jawan fields represent areas of hydrocarbon accumulation. Seismic attribute analysis showed low values of instantaneous frequency in the areas of hydrocarbon accumulation. Instantaneous phase was used to determine the limits of the sequence, the nature of sedimentation, and the type of vanishing, i.e. onlap vs. toplap. Low instantaneous amplitude values were recorded, indicating hydrocarbon reservoirs in the studied area. Various other seismic stratigraphic features were studied , including the distribution mound, flat spot, and channels in the two formations, but they were discontinuous because of the tectonic effects. These activities explain reasonably the distribution of hydrocarbons in the studied area.

Geodynamic Processes

This paper discusses the productive beds of the Urna and Ust‐Tegus oil fields (West Siberia, Russian) and permeability and capacity properties that are influenced by geodynamic processes. Strong tectonic processes, accompanied by periodic magma intrusions, produced numerous fractures and faults in the Jurassic sediments, which act as conduits for groundwater flows, and thus led to the hydrothermal alteration of rocks and changes in the pore space. The data presented in the paper testify to the manifestation of these processes in the modern hydrogeochemical and geothermal conditions of the Jurassic‐Cretaceous sediments within the two oil fields and their vicinity. The petrophysical studies of the core samples and the hydrodynamic studies in the wells confirm that the reservoir properties of the productive strata are considerably heterogeneous. Despite the significant effect of the geodynamic factors, the analysis of the tracer data has not revealed any apparent spatial consistency of the presence (or absence) of a hydrodynamic connection between the wells and the locations of fractured and dynamically stressed zones. In our study, we have proposed and tested a method based on the analysis of morphotectonic features detectable in the depth maps of reference surfaces. This method is a useful additional tool for discovering and analyzing the relationships between the tectonic and hydrodynamic conditions of oil and gas fields.

Hydrocarbon Reserves

The Browse Basin lies offshore from WA’s Kimberley region and hosts vast accumulations of natural gas, some are rich in condensate, making it Australia’s next major gas producing province on the North West Shelf. It is estimated that the Ichthys gas accumulation contains 12.8 trillion cubic feet (Tcf) of gas and 527 million BBL of condensate, and represents the largest hydrocarbon accumulation with recoverable liquids found in Australia since the discovery of the Gippsland Basin and Barrow Island oil fields in the 1960s. Similar amounts of gas, albeit drier (CGR 20–30 BBL/MMscf) are hosted within the Brecknock, Calliance and Torosa accumulations (cumulative of 15.9 Tcf gas and 436 million BBL condensate). For this reason, the Browse Basin continues to be a focus of exploration, in which both international companies and Australian explorers are capitalising on LNG opportunities. This extended abstract provides a summary of hydrocarbon accumulations encountered in the Browse Basin (up until late 2014). Accumulations discovered in the Browse Basin include: Abalone, Adele, Argus, Bassett, Torosa, Brecknock and Calliance, Ichthys, Concerto, Mimia, Burnside, Caspar, Caswell, Columba, Cornea, Focus, Sparkle, Crux (including Libra), Hippolyte, Echuca Shoals, Gwydion, Marabou, Poseidon (including Kronos, Boreas, Zephyros and Poseidon North), Crown (including Proteus and Pharos), Psepotus and Lasseter. The authors provide a summary of the regional geology, evolution and tectonic development of the basin, and discuss the hydrocarbon reserves and hydrocarbon potential of the basin. This provides a guide to assist potential future exploration programs in the Browse Basin.
