Nonstatic Reservoirs: The Natural State of the Geothermal Reservoir

Journal of Petroleum Technology, 1983
Summary Above-hydrostatic-reservoir-pressure gradients are found in many geothermal fields before exploitation. In higher-temperature fields, steam and water also coexist in the upper levels. These factors indicate natural upflow in these reservoirs-i.e. the dynamic state of the fluid.

Flow diagnostics for naturally fractured reservoirs

Petroleum Geoscience, 2018
Reliable production forecasting for fractured carbonate reservoirs is a challenge. Natural fractures, adverse wettability and complex matrix heterogeneity are all uncertain and can all negatively impact upon recovery. Ideally, we should consider different reservoir concepts encapsulated in a large ensemble of reservoir models to quantify the impact of ...

An Integrated Reservoir Description Method for Naturally Fractured Reservoirs

SPE Unconventional Gas Technology Symposium, 1986
ABSTRACT This paper presents a method to estimate reservoir properties and gas in place using both pressure transient test and production data from naturally-fractured reservoirs. The reservoir engineer needs to determine reservoir characteristics and gas in place to design and evaluate stimulation treatments and to predict performance ...

Naturally Fractured Reservoirs

2019
Currently, there are numerous of authors defined the fracture from a different perspective, However, from the geo-mechanical viewpoint; a fracture is defined as a surface in which a loss of solidity has taken place.

Simulations of Naturally Fractured Reservoirs

SPE Reservoir Engineering, 1988
Summary This paper describes a three-dimensional (3D), three-phase, black-oil model being used to simulate naturally fractured reservoirs. The program is fully implicit and can perform single-porosity, dual-porosity, or dual-permeability computations.

On the Nature of Reservoir-induced Seismicity

pure and applied geophysics, 1997
In most cases of reservoir-induced seismicity, seismicity follows the impoundment, large lake-level changes, or filling at a later time above the highest water level achieved until then. We classify this as initial seismicity. This “initial seismicity” is ascribable to the coupled poroelastic response of the reservoir to initial filling or water level ...

Naturally Fractured Reservoir Characterization

2006
Naturally fractured reservoirs present unique and specialized challenges to hydrocarbon extraction. Naturally Fractured Reservoir Characterization seeks to confront many of these challenges by providing an introduction to the engineering and geological character of naturally fractured reservoirs. The focus is on understanding fractures in a reservoir –

The Behavior of Naturally Fractured Reservoirs

Society of Petroleum Engineers Journal, 1963
Abstract An idealized model has been developed for the purpose of studying the characteristic behavior of a permeable medium which contains regions which contribute significantly to the pore volume of the system hut contribute negligibly to the flow capacity; e.g., a naturally fractured or vugular reservoir ...

Reservoirs of Brucella infection in nature

Biology Bulletin, 2010
Brucellosis is a zoonosis caused by bacteria of the genus Brucella, which includes nine species: B. melitensis (goats and sheep as the main reservoir hosts), B. abortus (cattle), B. suis (pigs), B. neotomae (desert woodrats), B. ovis (sheep), B. canis (dogs), B. ceti (whales), B. pinnipedialis (pinnipeds), and B. microti (Microtus voles).

Natural Fracturing in Carbonate Reservoirs

2013
Abstract Carbonate reservoirs are prone to natural fracturing. Fractures can act as enhanced permeability pathways, which may increase, decrease, or complicate reservoir production and development; healed fractures contribute to reservoir compartmentalization. A primary focus is placed upon the predictability of fracture set patterns and orientations,
