High-Resolution Subsurface Characterization Using Seismic Inversion—Methodology and Examples

Eng
Subsurface characterization for lithological and fluid properties is important for all aspects of geophysical exploration where estimating a high-resolution elastic property through seismic inversion is vital.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Tangent Blow‐Ups for Processing Non‐Manifold Geometry

Computer Graphics Forum, EarlyView.
Abstract Many geometry processing pipelines implicitly assume their input data is a manifold, or is sampled from one, with a unique tangent plane at every point. Geometric data, however, routinely contains sharp features like edges, corners, self‐intersections, branching junctions, and other singularities, rendering standard methods ill‐defined at ...

Estimating elastic properties of sediments by pseudo-wells generation utilizing simulated annealing optimization method

Results in Earth Sciences
The hydrate concentration model considerably affects elastic properties, including bulk and shear modulus. Defining seismic properties of sediments, such as compressional and shear wave velocity and density, provides valuable information to identify rock

Measuring the Stringency of Building Height Regulations

International Economic Review, EarlyView.
ABSTRACT This study proposes a novel methodology to measure the stringency of building height regulations. This measure gauges the difference in building heights with and without regulations. The primary challenge is to recover unobserved building heights in the absence of regulations.

Attenuation characteristics and wave impedance inversion of depth-domain nonstationary seismic data

Meitian dizhi yu kantan
BackgroundThe efficient application of depth migration methods has enabled the extensive implementation of depth-domain seismic data interpretation. Previous studies on the impacts of time-to-depth conversion and velocity models merely determine that an ...

Evolution, Routing and Reservoir Characteristics of Submarine Channels in a Structurally Deforming Slope Setting: Deep‐Water Joint Development Zone of Nigeria and São Tomé and Príncipe

Journal of Petroleum Geology, EarlyView.
ABSTRACT Deep‐water slope channels and associated facies are a major part of clastic sediment dispersal system extending from the shelf‐edge to the abyssal plain. The toe‐thrust area of the deep‐water Niger Delta enables the analysis of these channels and their interaction with evolving fault‐controlled sea‐floor topography to be determined ...

Bayesian inverse problems and seismic inversion

, 2016
The Bayesian formulation for inverse problems gives a way of making inferences about unknown quantities not directly observable. The application of Bayes' Theorem combines the prior information and the observation to give a posterior measure, which contains information about the quantity we are trying to estimate. In this thesis, we review a particular

1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

Incorporating burn probability into spatial prioritization of woodland caribou habitat restoration

Restoration Ecology, EarlyView.
Abstract Introduction Habitat disturbance is a major driver of population declines of woodland caribou in Canada. Habitat restoration is a critical component of a successful, long‐term approach to caribou recovery; however, with limited resources, it is important to target areas where restoration efforts will provide maximum benefits to caribou.
