We have done a geostatistical inversion of seismic data to facies probabilities. As a first step, we invert the seismic data for elastic parameters using the Bayesian AVA inversion method of Buland et. al. (2003). Next, we use an analysis of the uncertainty in the posterior distribution to filter the elastic parameters given in well logs. By comparing these filtered well logs with facies logs, ...

Definition and interpretation of sedimentary facies often involves examination of well logs to assess values, trends, cycles, and sudden changes. The procedure, which often includes visual inspection of the logs, could be improved by using recently developed signal analysis and feature extraction techniques. In particular, wavelet analysis of logs provides an easily interpretable visual represe...

Predrill pore pressure prediction of the NOVA well suggested that drilling program was in agreement with available seismic surveys. However, a kick encountered while during well. The study carried out to ascertain cause horizon Well, using attributes and log. Eight stratigraphic horizons were characterized describe amplitude variations. top base picked sculptured create sub-volume maps.The resu...

Much of the research in software engineering focuses on understanding the dynamic nature of software systems. Such research typically uses automated instrumentation or profiling techniques on the code. In this thesis, we examine logs as another source of dynamic information. Such information is generated from statements inserted into the code during development to draw the attention of system o...

This study focuses on the sequence stratigraphy and dominated seismic facies in Central Taranaki basin. Four regional sequences namely SEQ4 to SEQ1 from bottom top four boundaries representing unconformities H4 H1 have been traced based reflection terminations. was validated using well logs information. An onlapping feature section indicates a new perspective surface separated between upper low...
