WAVES - Advanced Sonic Data Processing and Fracture Evaluation Software
WAVES is a collaborative project developed by Saudi Aramco and Colchis PetroConsulting, designed to offer cutting-edge solutions for comprehensively analyzing full-waveform sonic data. It introduces a detailed and interactive workflow that enhances data processing capabilities. Utilizing advanced fracture evaluation techniques, WAVES leverages low-frequency Stoneley waveform data and dipole shear anisotropy for precise formation analysis. The software employs a state-of-the-art tomographic velocity profiling technique, providing inversions of velocity profiles along borehole radial and azimuthal directions, valuable for in-situ stress field studies. Its 3D wellbore visualization technology facilitates both visualization and integration of data, crucial for engineering decisions such as in completions and perforations. WAVES stands out with features like vendor-neutral DLIS data processing, dynamic and static elastic parameter conversion, and advanced acoustic logging modules. These modules aid in detailed fracture and anisotropy analyses, supporting comprehensive geological interpretations.- A comprehensive and interactive workflow for processing full-waveform sonic data.
- Advanced fracture evaluation that utilizes low-frequency Stoneley waveform data and dipole shear anisotropy analysis.
- The latest tomographic velocity profiling technique, which provides the inverted velocity profiles along the borehole radial / azimuthal direction. This can serve as a new input for in-situ stress field study.
- The latest technology for visualizing wellbores in 3D. It is developed for both data visualization and data integration.
Solid vendor neutral DLIS data decomposing and loading.
The interactive acoustic time difference picking and editing module provides high-quality P-wave, S-wave and Stoneley wave time difference curves.
The rock mechanics module provides dynamic and static elastic parameter conversion as well as engineering parameters such as Young's modulus and Poisson's ratio.
The fracture interpretation module of the stoneley wave is used to distinguish the developed strata and formation boundaries of open fractures.
The orthogonal dipole shear wave anisotropy processing module is used to interpret the direction of high Angle fracture and maximum horizontal principal stress.
Velocity profile inversion of p-wave and dipole s-wave tomography provides radial velocity variation profile caused by drilling effect, which is a new input for in-situ stress field study.
Azimuth p-wave tomography velocity profile inversion also provides radial and multidirectional velocity profiles, which can be used to image near-wellbore drilling damage and study in-situ stress fields.
Patented full 3D wellbore visualization technology provides 3D visualization and integrated data interpretation of all measurements and interpretation results. That will provide high-quality input for subsequent engineering design of completions, perforations or horizontal Wells.
