Toward high-definition reservoir characterization
A new methodology for high resolution reservoir characterization is proposed. It combined the advantages of the surface seismic (low resolution, large coverage) and crosswell seismic (improved resolution, small coverage).;The process involves deconvolution of a low resolution signal (surface …

Reservoir characterization using intelligent seismic inversion
… different scales is the major challenge in reservoir characterization studies. Seismic data is among those different types of data, which is usually used by geoscientists for structural mapping of the subsurface and making interpretations of the reservoir's facies distribution. Yet, it has …

Reservoir characterization using seismic inversion data
<p>Reservoir architecture may be inferred from analogs and geologic concepts, seismic surveys, and well data. Stochastically inverted seismic data are uninformative about meter-scale features, but aid downscaling by constraining coarse-scale interval properties such as total thickness and average …

Reservoir characterization using seismic reflectivity and attributes
The primary objective of this thesis is to obtain reservoir properties, such as porosity from surface seismic data complemented by available well logs. To accomplish this a two-step procedure is followed. First, reflectivity and acoustic impedance profiles are obtained from the inversion of …

Study of induced seismicity for reservoir characterization
… attributes of conventional and unconventional reservoirs through passive seismicity. The dissertation is comprised of the development and applications of three new methods, each of which focuses on a different aspect of fractures/faults and the resulting seismicity. In general, the thesis work …

Oil reservoir characterization using ensemble data assimilation
… oilfields that provide real-time measurements of reservoir conditions. These measurements can be used for more frequent reservoir model calibration and characterization that can lead to improved oil recovery though model-based closed-loop control and management. This thesis proposes an efficient …

Data Integration and Reservoir Characterization of the Pennsylvanian Bartlesville Sandstone
… of these programs is dependent upon accurate characterization of the reservoir. Because most of the drilling occurred many decades ago, much of the data associated with this field predates electric well logging and has not been integrated with contemporary databases.</p> <p>To establish a more …

Reservoir Characterization of the Clarksville Formation in Red River County, Texas
… lithofacies, Sandstone 1 exhibits the highest reservoir quality, while diagenetic processes including clay, hematite, and calcite cementation exert a strong control on porosity and permeability across the formation.</p>

Reservoir Characterization of the Broom Creek Formation For Carbon Dioxide Sequestration
… the design is to characterize the Broom Creek’s reservoir properties and provide detailed results of CO2 sequestration capacity, plume migration, and safety level. The methodology used to obtain results is an incorporation of geology, reservoir engineering, and injection operations. The reservoir …

Numerical reservoir characterization using dimensionless scale numbers with application in upscaling
… of dimensionless variables in numerical reservoir simulation and experimental design motivated the development of a complete set of dimensionless scaling groups. Inspectional analysis yielded 8 dimensionless groups completely describing the flow system. Further analysis of fluid …

Reservoir characterization of the Deadwood formation western North Dakota, Williston Basin
… research shows that the conventional hydrocarbon reservoirs of the Deadwood Formation are not as lucrative as previously understood. Consequently, the current research focuses on these basal siliciclastic sands for emerging renewable energy sectors such as carbon capture sequestration (CCS) and …

Full waveform inversion combining rock physics for seismic reservoir characterization and monitoring
… and fluid saturation, is an important part of reservoir characterization. Most current seismic workflows in this field are based on amplitude variation with offset (AVO). Full waveform inversion (FWI) methods, although computationally more complex than AVO approaches, can produce more accurate …

Improved reservoir characterization by incorporating geodetic data in a western Kazakhstan oilfield
Reservoir characterization for petroleum systems stands as a key source of competitive advantage amongst operators. Exploration and field development activities require large investments of engineering time and capital to be made in pursuit of improved short- and long-term economic decision-making …

Induced seismicity analysis for reservoir characterization at a petroleum field in Oman
… aspect of the seismic data to infer the reservoir properties. First, I applied three different methods (the iterative linearized, nonlinear grid-search, and double-difference methods) to relocate 405 microearthquakes that occurred between October 1999 and June 2001 in a producing field in …

Sedimentologic and lithostratigraphic properties and reservoir characterization of the Winnipeg Formation, Southern Saskatchewan
… for deciphering the depositional environment, reservoir properties, and cyclostratigraphic analysis of the studied rocks. Ten lithofacies (eight quartz arenite and quartz wacke sandstones, one siltstone, and one shale) are recognized and interpreted as beach to lower offshore accumulations. The …
