Well-log Analysis of Shale Gas Reservoirs
2021Well-logs provide continuous information about rocks and their pore fluid properties. Typical well-logs such as gamma-ray, density, neutron, sonic, and resistivity logs have been traditionally used to estimate shale volume, porosity, lithology, and fluid saturation in conventional oil and gas exploration, where shale formations are treated as ...

Wavelet analysis using well log information
SEG Technical Program Expanded Abstracts 1988, 1988An important problem in detailed lithologic studies from seismic data is the estimation of the signal wavelet. A methodology is proposed for estiiation of the wavelet using borehole information. In the processing sequence the wavelet amplitude and phase spectra re gradually investigated.

Well Logging Analysis in Niger Delta Basin
SPE Nigeria Annual International Conference and Exhibition, 2021Abstract A hydrocarbon exploration begins with the geological recognition of probable hydrocarbon accumulation areas, which are confirmed by seismic survey and, to ensure certainty, it is necessary to drill a well. On those exploration wells measurements are made down the hole for the formation evaluation.

Conventional Well Log Analysis
1985The program is designed to provide the values of water saturation, porosity, hydrocarbon index, and movable oil index for each subinterval analyzed. In addition, the program provides average values of porosity, water saturation (Archie method, 1942), and net pay thickness for the total interval based on user-selected cut-off parameters.

Wigner distribution analysis of acoustic well logs
ICASSP '87. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005We use the Wigner distribution(WD) mixed time-frequency representation(TFR) to design two heuristic algorithms that can be used to analyze and separate the compressional(P), shear(S), Pseudo-Rayleigh (PR), and Stoneley(ST) wave components of the multi-component time-varying borehole seismic signals recorded in well logging velocity surveys.

Performance analysis for acoustic well logging receivers
The Journal of the Acoustical Society of America, 2012The structure of acoustic logging receivers can change their performance directly. In this article, impedance characteristics and receiving sensitivities of three kinds of acoustic logging receivers were numerically analyzed with the finite element method.

Abstract This publication is a general introduction to common openhole logging measurements, both wire line and MWD/LWD, and the interpretation of those measurements to determine the traditional analytical goals of porosity, fluid saturation, and lithology/mineralogy. It is arranged by the interpretation goals of the data, rather than by

A Real-Time Well Site Log Analysis Application Using MRI Logs
SPE Annual Technical Conference and Exhibition, 2000Abstract With any complex logging tool, there exists a need for a "qualitative and reasonable" analysis, run in real-time at the well site that both provides a preliminary interpretation of the data and also serves as a means for enhancing quality control.
