The Three-Dimensional Geologic Model Used for the 2003 National Oil and Gas Assessment of the San Joaquin Basin Province, California

We present a three-dimensional geologic model of the San Joaquin Basin (SJB) that may be the first compilation of subsurface data spanning the entire basin. The model volume spans 200 × 90 miles, oriented along the basin axis, and extends to ~11 miles depth, for a total of more than 1 million grid nodes. This model supported the 2003 U.S. Geological Survey assessment of future additions to reserves of oil and gas in the SJB. Data sources include well-top picks from more than 3,200 wildcat and production wells, published cross sections, regional seismic grids, and fault maps. The model consists of 15 chronostratigraphic horizons ranging from the Mesozoic crystalline basement to the topographic surface.

The Three-Dimensional Geologic Framework Modeling of
Faulted Hydrostratigraphic Units within the Edwards Aquifer,
Northern Bexar County, Texas

This report describes a digital, three-dimensional faulted hydrostratigraphic model constructed to represent the geologic framework of the Edwards aquifer system in the area of San Antonio, northern Bexar County, Texas. The model is based on mapped geologic relationships that reflect the complex structures of the Balcones fault zone, detailed lithologic descriptions and interpretations of about 40 principal wells (and qualified data from numerous other wells), and a conceptual model of the gross geometry of the Edwards Group units derived from prior interpretations of depositional environments and paleogeography.

Creating 3D Models of Lithologic ⁄ Soil Zones using 3D Grids

Aside from describing and recording surficial geology, mapping of the subsurface is, for geologists, one of the most frequently performed tasks. Traditionally, surface contacts are integrated with data gathered in vertical borings, usually drillers' logs, and correlations are manually interpreted on sections between the borings. Contour maps can then be made, manually, or by computer from the surface and correlated borehole data. In this paper, I will describe a work path using the same data, but bypassing the manual correlation step, to create ...

Gravity Calculations from 3D, Geologically Driven Models: A New Approach

This work introduces a geologically based approach for calculating the gravity anomaly of any 3-dimensional (3-D) earth model with arbitrary density distribution. The calculation uses a 3-D modeling software package that facilitates model building using true geological operations such as deposition, erosion, faulting etc. Hence, models are not necessarily built from unnatural polyhedra, a shortcoming of many previous modeling schemes.

Multi-Disciplinary Teamwork Delivers Outstanding Krechba Horizontal Well Performance

Krechba is one of seven fields in the In Salah Gas Development in District 3 of Algeria. Early in the FEED stage for Krechba up to 25 vertical wells were envisaged to develop the thin Carboniferous reservoir. To reduce development costs, feasibility studies were performed on the option of drilling 6–8 horizontal wells, which included 2–3 CO2 injection wells. This option was later adopted in the Development Plan. The horizontal wells were planned with 1000m horizontal legs, but in the execution phase this target was increased to 1500m to increase well deliverability and injectivity.

Three-dimensional Geologic Modeling and Horizontal Drilling Bring More Oil out of the Wilmington Oil Field of Southern California

The giant Wilmington oil field of Los Angeles County, California, on production since 1932, has produced more than 2.6 billion barrels of oil from basin turbidite sandstones of the Pliocene and Miocene. To better define the actual hydrologic units, the seven productive zones were subdivided into 52 subzones through detailed reservoir characterization. The asymmetrical anticline is highly faulted, and development proceeded from west to east through each of the 10 fault blocks. In the western fault blocks, water cuts exceed 96%, and the reservoirs are near their economic limit. Several new technologies have been applied to specific areas to improve the production efficiencies and thus prolong the field life.

3D Lithofacies Model Building of the Rotliegend Sediments of the NE German Basin

Static 3D geological models are essential to reservoir characterization and dynamic models. We introduce an approach of combining pre-existing and newly generated data to assess lithofacies distributions and sandstone permeability of a clastic reservoir within the Rotliegend II of the NE German basin. The target is in 4300 m depth and situated north of Berlin (Germany) in the vicinity of a former gas exploration well, drilled in 1990 and currently acting as geothermal in-situ laboratory.

Heterogeneity within the subducting Pacific slab beneath the Izu–Bonin–Mariana arc: Evidence from tomography using 3D ray tracing inversion techniques

Distinct zones of seismic heterogeneity along the Izu–Bonin–Mariana arc have been investigated using complimenting regional bulk sound, shear wave speed, and P-wave tomographic images. The distribution of seismic anomalies and the inferred geometry of the subducting Pacific plate have been modelled in unprecedented detail using joint tomography and new P-wave model using a 3D inversion algorithm. The use of 3D ray tracing techniques and smaller cell parameterizations have greatly enhanced the resolution of gradients, therefore, the models show much more detail about the structure and physical properties of the subduction zone.

Characterisation of the Tectono-Sedimentary Evolution of a Geothermal Reservoir—Implications for Exploitation (Southern Permian Basin, NE Germany)

The characterisation of the tectono-sedimentary environment as well as the knowledge of the recent maximum horizontal stress regime in reservoir scale is crucial for projecting directional and horizontal drilling of multiple borehole geothermal systems. This is necessary to initiate optimal conditions for hydraulic conductivity of faults and fractures inside the reservoir.

Evolution of mantle structure beneath the northwest Pacific: Evidence from seismic tomography and paleogeographic reconstructions

Plate motions and subducting slab morphology are intricately connected, and through the integration of seismicity, tomographic images, and relative plate motions, the evolution of mantle structure can be interpreted. Tomographic images of P wave, shear wave speed, and bulk sound speed perturbations of the northwest Pacific region have been interpreted to define the extent and geometry of the subducting Pacific plate. We have found that the subducted Pacific plate beneath the Japan and Kurile arcs is coherent but is very complex at the junction of the two arcs near the Hokkaido corner, as the slab subduction angle decreases from north to south while the slab thickens.

A 3-Dimensional Model of Water-Bearing Sequences in the Dominguez Gap Region, Long Beach, California

A 3-dimensional computer model of the Quaternary sequence stratigraphy in the Dominguez gap region of Long Beach, California has been developed to provide a robust chronostratigraphic framework for hydrologic and tectonic studies. The model consists of 13 layers within a 16.5 by 16.1 km (10.25 by 10 mile) square area and extends downward to an altitude of –900 meters (-2952.76 feet). Ten sequences of late Pliocene to Holocene age are identified and correlated within the model. Primary data to build the model comes from five reference core holes, extensive high-resolution seismic data obtained in San Pedro Bay, and logs from several hundred water and oil wells drilled in the region.

The Influence of an Integrated Remedial System on Groundwater Hydrology

This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored natural attenuation (MNA) and phytoremediation instituted to further reduce dissolved-phase contaminants. Monitoring of natural attenuation parameters indicates that abiotic and biotic degradation is significantly reducing 1,1,2,2-TeCA concentrations. Phytoremediation is provided by a 4.5-year-old plantation of 172 hybrid poplars observed to be seasonally influencing groundwater hydrology. A 3D-geospatial model (EarthVision®), which was constructed ...
