چکیده

Many innovative approaches to using data to make inferences about aspects of the natural world necessitate the calculation and appraisal of large numbers of alternative models or the repeated sampling of a multi-parameter solution space. While this is not new to science, it has hitherto been restricted to either very simple models, or to institutions with powerful computing infrastructure. Such institutions include large commercial companies and publicly funded computing initiatives, generally housed at universities or government research establishments. Advances in desktop and notebook computer processing and data storage capabilities now enable a variety of multiple-model approaches to geophysical data inference to be carried out on personal computers. It is therefore timely reconsider such approaches as innovative in recognition of their newly increased potential for widespread use. We also illustrate an innovative algorithm that is highly applicable to many aspects of geoscience. SUMMARY

A Robust Methodology for Prediction of DT Wireline Log

DT log is one of the most frequently used wireline logs to determine compression wave velocity. This log is commonly used to gain insight into the elastic and petrophysical parameters of reservoir rocks. Acquisition of DT log is, however, a very expensive and time consuming task. Thus prediction of this log by any means can be a great help by decreasing the amount of money that needs to be allo...

Paleoenvironmental Reconstruction of Miocene Surma Succession in the Well Rashidpur # 04 of Bengal Basin Using Log Facies Interpretation

Detailed log facies studies of Miocene succession in the well Rashidpur-04, Rashidpur structure, Surma Basin were carried out by integrating wireline log and limited core sample data in order to reconstruct the paleoenvironments of deposition. Based on the analysis of the log motifs, grain size, sand/shale ratio and major change in gamma ray log motifs, two major depositional sequences were ide...

Fuij.. Waveform Acoustic Logging - Where We Are. Where We Are Going Dependence on Tool Response Volume of Data Comparison of Log Velocities Comparison with Laboratory Data

We have now completed the second year of the Full Waveform Acoustic Logging Consortium. During these two years, we have developed a good understanding of seismic wave propagation in a borehole through both theoretical modelling and data interpretation. If we were to make a simple statement about the full waveform acoustic log, it would be that the method has far greater potential for determinin...

Implementing Direct and Indirect Wireline Methods in Determination of Total Organic Carbon: A Case Study from a West African Hydrocarbon Field

Since the development bloom in unconventional reservoirs in North America, total organic carbon (TOC) has become a more essential parameter, as the indicator of the efficiency of these reservoirs. In this paper, by using conventional well logs and NMR log data, the TOC content of an unconventional reservoir in West Africa is estimated. Passy’s, Issler’s, and Schmoker’s methods were used as indi...
