"The thesis of Philipp Antrett is concentrated on reservoir houses, petrography, lithofacies and sedimentology, center research and nanoporosity reports. it is going to be of significant curiosity for colleagues all for the exploration and creation of tight gasoline reservoirs in Northern Europe and elsewhere."
- François Roure, August 2012

This thesis describes a multidisciplinary, multiscale method of the research of tight fuel reservoirs. It concentrated at the start at the facies structure of a Permian tight gasoline box within the Southern Permian Basin (SPB), East Frisia, northern Germany. to enhance box improvement, 3D seismic information, wireline and middle info have been in comparison to a reservoir analogue within the Panamint Valley, California, usa. as well as the big scale process, a piece circulation that investigates microporosity via combining Scanning Electron Microscopy-Broad Ion Beam (SEM-BIB) and optical microscopy used to be built. For a greater figuring out of the depositional surroundings and reservoir rock distribution within the SPB, a sedimentary facies research of 4 cores from the tight gasoline box in East Frisia used to be in comparison to a moment examine sector in northern significant Germany. This examine demonstrates that tight fuel exploration and construction calls for multidisciplinary, multiscale ways past average seismic interpretation paintings flows to raised comprehend the temporal and spatial evolution of those complicated reservoirs.

Download e-book for iPad: Faults and Subsurface Fluid Flow in the Shallow Crust by William C. Haneberg, Peter S. Mozley, J. Casey Moore, Laurel

Released by way of the yankee Geophysical Union as a part of the Geophysical Monograph sequence. This quantity bargains a pattern of the range of analysis on faults and fluid stream within the overdue Nineteen Nineties. It describes precise floor and subsurface characterization of fault-zone constitution and diagenesis with implications for hydrology and petroleum geology; the function of faults in geothermal platforms; laboratory reports of rock mechanics, permeability, and geochemistry of faults and fault rocks; and mathematical modeling of fluid move via faulted and fractured rocks.

Sample text

Desiccation from water table reduction or climatic factors and the accompanying swelling and shrinking of clay minerals played an important role in this genesis. Messina et al. [26] discuss that this type of crack development is initiated in the subsurface. Due to the repeated change in clay volume through drying and dewatering, fractures develop in the surrounding sediment, and the fissures start to grow towards the playa surface. Neal and Motts [29] state that polygon dimensions depend on the ephemeral or long-term nature of desiccation.

Black arrows indicate locations of major outlines (see Fig. 6), mostly associated with faults on seismic surfaces. White arrows mark positions of sub-ordinate outlines with no offset or amplitude variation. b Polygonal pattern on cropped seismic volume of an ant tracking z-slice in the foreground. Effect of pattern displayed in vertical seismic line: negative relief of the reflectors not in all cases accompanied by faults. Sometimes no change in amplitude occurs at all. Top Rotliegend horizon sketched in black, faults in red allowed and three legal steps required.

A striking unconformity developed at the base of the Cretaceous [47]. Furthermore, salt rim synclines adjacent to the salt dome suggest the presence of a topographic relief as a result of salt piercing the surface [28, 48]. Salt deformation still affected deposition during the Tertiary (Fig. 3). 2 Depositional Setting The Upper Rotliegend II of the SPB is dominated by siliciclastics and minor evaporites deposited under arid to semi-arid climate [16, 17]. Four facies associations were identified to reflect the deposition in ephemeral fluvial (wadi), aeolian, sabkha and lacustrine environments [15, 24, 42].
