Summary
This study introduces effective attributes to better characterize shale gas reservoirs using seismic data. These attributes improve the correlation between reservoir properties like organic matter and brittleness and seismic responses, aiding in prospect assessment.
Area of Science:
- Geophysics
- Petroleum Geoscience
- Reservoir Engineering
Background:
- Unconventional resource production, like shale gas, relies on reservoir properties: organic matter and rock brittleness.
- Characterizing these properties using seismic data is challenging due to poor correlation with elastic properties.
Purpose of the Study:
- To develop a method for improved spatial characterization of shale reservoir properties using seismic data.
- To establish a better correlation between reservoir properties and seismic attributes.
Main Methods:
- Proposed an 'effective attributes' method by dividing organic shale reservoir properties into hard and soft elastic responses.
- Analyzed a worldwide laboratory dataset to correlate these components with P- and S-wave impedance.
- Applied the method to inverted P-wave impedance seismic data from the Sembar shale.
Main Results:
- Identified that hard and soft components show a significantly better linear correlation with P- and S-wave impedance.
- The effective attributes successfully reduced the gap between reservoir properties and seismic characteristics.
- Demonstrated successful results in quantifying unconventional prospect on a seismic scale using Sembar shale data.
Conclusions:
- The proposed effective attributes are key controlling factors for rock elastic properties, providing insights into hydrocarbon potential and brittleness.
- This methodology can be reliably applied globally for assessing unconventional reservoir potential.

Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.

01:12Elasticity
4.5K
Elasticity is the ability of an object to withstand the effects of distortion and to return to its original size and shape once the forces causing deformation are removed. When an elastic material deforms under the action of an external force, it experiences internal resistance to the deformation. However, if no external force is applied, it returns to its original state.

Upon subjecting concrete to moderate or high uniaxial compressive or tensile stresses, the strain response is non-linear relative to the stress applied. As the stress is removed, the resulting stress-strain curve deviates from the original path traced during loading, creating a hysteresis loop, indicative of the concrete's non-linear and non-elastic properties. Typically, a material's modulus of elasticity, which is a measure of the material's stiffness, is inferred from the linear...

01:05Estimation of the Physical Quantities
7.1K
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...

01:20Elastic Strain Energy for Shearing Stresses
437
As discussed in previous lessons, strain energy in a material is the energy stored when it is elastically deformed, a concept crucial in materials science and mechanical engineering. This energy results from the internal work done against the cohesive forces within the material. When a material undergoes shearing stress and corresponding shearing strain, the strain energy density, which is the energy stored per unit volume, is calculated. Within the elastic limit, where the stress is...

01:01Elastic Potential Energy
19.3K
Elastic potential energy is the energy stored as a result of the deformation of an elastic object, such as the stretching of a spring. An object is elastic if it returns to its original shape and size after being deformed.
Potential energy is also associated with the elastic force exerted by an ideal spring. The work done by this force can be represented as a change in the elastic potential energy of the spring. Thus, the work done by a perfectly elastic spring, in one dimension, depends...
