... producing from a monocline with an edge-water aquifer. Although such problems can be computed with reservoir simulation, the objective of this work was to develop simple empirical correlations for predicting water production behavior from a monocline reservoir. The reservoir model was described as a single...

... I derive accurate anisotropy parameters for monoclinic anisotropy model with a horizontal symmetry plane based on NMO ellipses for P-, S1- and S2-waves. These parameters are illustrated for benchmark model consisting of two non-orthogonal fracture sets embedded into transversely isotropic medium...

... important for considerations related to field development and production. A fractured reservoir may have multiple vertical fracture sets and, as a result, the rock’s elastic symmetry may be monoclinic. Thus, AVAz inversions based on reflectivity equations associated with higher symmetries will not be valid...

... that varies with depth. Such a model requires a monoclinic treatment. We utilize exact anisotropic ray theory to compute ray paths, times and reflection amplitudes. After a theoretical description we show results of two-point ray tracing through the SEAM 2 1D model, which contains a depth-variable symmetry...

... ABSTRACT Reflection and transmission (R/T) responses depict the energy distributions for waves traveling across the interface. We consider a model made up of two welded monoclinic half spaces to analyze the R/T coefficients. The monoclinic media have a horizontal symmetry plane parallel...

... propagation, which can be useful for algorithms dealing with 3D processing or correlation between VSP. The derivation of expressions for media with horizontal transverse isotropy, orthorhombic and monoclinic symmetries is shown. These expressions are based on the well known Thomsen like parameters that give...

... and the initial position of the zone. Each of these parameters, which can be varied laterally along fault strike in Midland Valley’s Move software, will ultimately influence the fault–fold relationship. Here we present a case study on the development of the East Kaibab monocline in the western United States...

According to the basin modeling results, the oil and gas source rocks identified within the Visim megaswell failed to reach hydrocarbon generation windows. A more subsided position...

.... A near-vertical faulting system was mapped that may pose uncertainties to the sealing capacities of the caprock layer. The preliminary structural map shows a relatively flat topography that deepens to the east; and a high area in the west-northwest that is produced by faulting within a Hogback Monocline...

Where the salt is absent in Silo, a thickened Dakota-Sundance interval compensates for the lack of salt. This compensation creates a structural monocline...
