... Abstract A persistent challenge in reservoir modeling is to assign representative values for vertical permeability in reservoir models. It is a common practice to use kv/kh directly from the core measurements but this is not at the same scale as the model grid. It is also frequent to use one...

... the magnitude of the natural energy of the reservoir that contributes significantly (15-20%) to the energy loss. A revelation that changed the reservoir development strategy going forward. It inspired innovative methods to capture horizontal and vertical permeability needed to reproduce field performance...

... such as horizontal and vertical permeabilities from simultaneous nonlinear matching of transient pressure data sets that are spatially distributed. All geological and openhole log data, including high resolution image logs are utilized to construct a detailed reservoir model. In the presence of fractures and faults...

... into a geocellular grid model in which geometries of the large fractures were maintained explicitly. The calculation of effective horizontal and vertical permeabilities of the fracture system was scale dependent and decoupled. Fracture geometric parameters and permeabilities were calibrated against well test data...

.... The initial believe was that fine grained and mm scale laminated sediments act as vertical baffles for the steam distribution. The fine grained sands were low in permeability and the lamination were further reducing the vertical permeability. Grain size had the main impact on permeability and grain size...

... Abstract This paper introduces the history matching process of commingled wells and demonstrates how to reduce the uncertainty of the vertical permeability ratio (kV/kH) by analyzing the production logging results of horizontal wells which have been used only for allocation through...

... Abstract Quantifying the vertical permeability and sealing capability of the stylolite zones in a Middle East carbonate reservoir is critically important for the enhanced recovery, water coning, perforation policy and well-placement choices. A wireline formation tester was used to perform four...

... behave as barriers, baffles, or open channels to fluid flow in the reservoir and often cause early water breakthrough, gas channeling, etc. that are costly. In this paper, we use 3D interval pressure transient tests to estimate horizontal and vertical permeabilities and to delineate of fracture...

... Abstract One of the key uncertainties that impacts reservoir development and waterflood performance in a thick reservoir is vertical transmissibility across the stylolitic intervals. It is not clearly understood whether low vertical permeability or negative capillary pressure across stylolites...

..., particularly resistivity images. Vertical communication across tested zones and individual layer horizontal and vertical permeabilities are obtained. High permeability zones were identified with some lateral continuity across wells. Some zones were found to be local permeability barriers with well developed...

... Abstract An accurate knowledge of vertical permeability (kv) in a thick reservoir is critically important to the design of a successful reservoir sweep development. However, the in-situ vertical permeability is very difficult to ascertain and may not be the same as those measured from core...
