Formation waters in petroleum reservoirs : their controls and applications
… from nine different locations (predominantly petroleum reservoirs) on five continents were evaluated. This information, together with local mineralogy, depth and temperature relations provided a sound basis from which to investigate the most important controls on formation water composition. …

Analysis and modeling of induced seismicity in petroleum reservoirs
Since 1998, a producing oil field in Oman has been experiencing microearthquake activity. The aim of this project is to compare numerical models of wave propagation using simple source representations to a small subset of these microearthquakes, with three goals in mind: 1) to understand whether …

Convergence of material balance in mathematical simulation of petroleum reservoirs
<p>One criterion for determining the precision of pressures calculated by a simulation model is the accuracy of the material balance. A high degree of precision in the calculated pressures is a necessary condition for elimination of error in prediction of fluid migration in the reservoir. However, …

Caprock integrity evaluation for geosequestration of CO2 in depleted petroleum reservoirs.
… gases before the CO2 can be stored in depleted petroleum reservoirs or aquifers - or, it might be necessary to inject CO2 with a small amount of these gas impurities to save cost. Moreover, during CO2 geosequestration in reservoirs, pressure variations during injection and storage could force …

An application of residual relaxation to mathematical simulation of petroleum reservoirs
… of numerical techniques to the simulation of petroleum reservoir performance. An iterative method based on sequentially reducing the residual to zero at each grid point has been developed. It has been shown analytically that this residual relaxation method is stable, convergent, and …

Analysis and interpretation of clustered microseismicity at geothermal and petroleum reservoirs
… microearthquake clusters near geothermal and petroleum reservoirs. One cluster was induced during a controlled hydraulic fracture experiment conducted by Atlantic Richfield Corporation (ARCO). The other three clusters occurred near geothermal fields in western Italy during condensate …

The simulation of single phase, compressible fluid flow in fractured petroleum reservoirs using finite elements
In this thesis, commonly used equations governing the flow of fluids are reviewed, from first principles where appropriate. The assumptions that are made in the process are critically assessed and their limitations are discussed. The equations deal with flow through a porous and permeable medium, a …

Mathematical simulation of gas and water coning in petroleum reservoirs by the dynamic material balance technique
<p>"The prediction of coning behavior at a producing oil well is one of the most difficult numerical simulation problems. Because of the convergent flow patterns and small sizes of the inner grid blocks, the radial coordinate models used to study the problem have a tendency to become unstable. …

An Approach to Mapping of Shallow Petroleum Reservoirs Using Integrated Conventional 3D and Shallow P- and SH-Wave Seismic Reflection Methods at Teapot Dome Field in Casper, Wyoming
… a clearer picture of both very shallow reservoirs and the relationship between deep and shallow faults can be observed. For example, we show that the Shannon reservoir, which is the shallowest petroleum reservoir at Teapot Dome (depth to the top of this interval ranging from 76-198 m …

Analysis of Tripolitic Chert in the Boone Formation (Lower Mississippian, Osagean), Northwest Arkansas and Southwestern Missouri
… reservoir characterization in subsurface petroleum reservoirs in the mid-continent that are laterally equivalent to the Boone Formation. The Boone exposures are used as analogs for subsurface carbonate intervals in the Mississippi Lime Play. Results from Petrographic, SEM, EDX, and …

Theoretical and experimental investigation of oil recovery by the electrothermic technique
… the feasibility of increasing oil recovery from petroleum reservoirs by the electrothermic technique. A mathematical model was developed for the prediction of reservoir response to heating by alternating electric current flow through the oil-bearing formations. The mathematical model was …

Incorporation of fault rock properties into production simulation models
… in simulating fluid in structurally complex petroleum reservoirs. Microstructural and petrophysical measurements are conducted on faults from core within the Pierce Field, North Sea. The results are used to calculate transmissibility multipliers (TMs) required to take into account the effect …

Remote Sensing of Hydrocarbon-induced Rock Alterations at Cement Field, Oklahoma
… seepage is the escape of oil and gas from petroleum reservoirs and their upward-migration to the surface. These hydrocarbons at the surface can generate rock alterations, including mineralogical changes, bleaching of red beds, and clay mineral alterations. Surficial expressions of such …

A Three-dimensional Model of Poroviscous Aquifer Deformation
… some modifications, is potentially applicable to petroleum reservoirs. A porous medium saturated with water is conceptually treated in the model as a nonlinearly viscous fluid continuum. The model employs a new three-dimensional extension, made in this thesis, of Helm's poroviscosity as a …

Upper Jurassic (Oxfordian) Smackover facies characterization at Little Cedar Creek Field, Conecuh County, Alabama
… the Kimmeridgian Haynesville Formation. The petroleum reservoirs in Little Cedar Creek Field, unlike most Smackover fields in the eastern Gulf region, are composed predominantly of limestone, not dolomite, and do not possess a Buckner Anhydrite top seal immediately above the reservoir. …

Analytical and Semi-Analytical Models for Composite Reservoirs with Complex Well Completions
… are fundamentally different from conventional reservoirs for which there is an abundance of high-yield technical know-how. In a technical sense, these plays are not reservoirs but source rocks; their permeabilities are in the micro- to nano-darcy range. Hence, they cannot sustain economic …

Three-dimensional eolian bounding surface architecture of the Entrada sandstone, Utah: expanding our understanding of reservoir heterogeneity in wet eolian systems
… erg evolution. Eolian deposits form noteworthy petroleum reservoirs (e.g., Norphlet Formation, Rotliegend Group, and the Tensleep Sandstone), but bounding surface architecture imparts significant reservoir heterogeneity. In order to understand dune morphodynamics, reconstruct ancient erg …

Use of hydraulic tests to identify conceptual models of heterogeneity for fractured rock aquifers
Important aquifers, petroleum reservoirs, geothermal reservoirs, and waste disposal sites throughout the world are located in fractured rock formations. Responsible management of these resources and sites requires appropriate field characterization studies and modeling techniques to assess the …
