Seismic wave attenuation is affected by wave-induced pore fluid dissolution. The mechanism of dissolution the mutual between different fluids caused pressure. Compared with traditional WIFF (wave-induced flow) mechanism, can predict seismic frequency band and be used in well-to-seismic calibration. Conventional methods neglect velocity dispersion interaction fluids, which will lead to errors pr...

Seismic horizon tracing is a key step in seismic data interpretation. At present, it mainly relies on manual interpretation to mark the layers within region. The deficiency of lies its low precision and efficiency, heavily experience interpreter. Aiming at above problems, author proposes an automatic tracking algorithm with curvature constraint. firstly determines initial seed points based logg...

Panax Geothermal Limited is developing a geothermal resource in South Australia, the Limestone Coast Project, which is a conventional “hot aquifer” reservoir in a deep sedimentary basin. The initial development is the Pretty Hill Formation sandstones in the Penola Trough of the Otway Basin. The area is an exploited gas basin with modern 3D seismic and excellent existing petroleum well data cove...

In this article we present a novel method for the estimation of sulphur deposit resources based on high-resolution shallow reflection seismic survey and well logging. The study area was sited in northern part Carpathian Foredeep (SE Poland), where ore occurs carbonate rocks at depth about 120 m, with thickness approximately 25 m. results many years monitoring performed allowed us to determine q...

in this research resistance of six tree species to logging damages (bole wound) after 12 years were studied in district 1 of asalem nav forests. the data of extent and severity of damages on residual trees were collected immediately after logging operation from systematic sampling with circular 0.1 ha plots in the year of 2000. the damaged trees and wounds condition were reexamined in the year ...

An appropriate velocity model from well logs is a key issue in the processing and interpretation of seismic data. In deep borehole located central part Polish Outer Carpathians, sonic measurements were inadequate for purposes due to poor quality data gaps logging. Multiple regression (MR) modified Faust equation proposed log. MR estimated P-wave slowness as dependent variable on basis sets vari...

A new method based on generalized reflection and transmission coefficients is proposed to calculate the synthetic seismograms in radially multilayered media. This method can be used to efficiently simulate full waveform acoustic logs and crosswell seismic profiles in situations where we need to consider borehole effects. The new formulation is tested by comparing our numerical results with prev...
