A Fuzzy Symbolic Representation for Intelligent Reservoir Well Logs Interpretation
نویسندگان
چکیده
Well log data are routinely used for stratigraphic interpretation of the earth’s subsurface. This paper presents an automatic blocking scheme that transforms numerical well log data into a fuzzy symbolic representation. This representation maintains the character of the original log curves, which is essential for the stratigraphic interpretation, while making the interpretation task easier. Additionally, fuzzy symbols allow effective interpretation under uncertainty embedded in the data set and our knowledge of the earth’s subsurface. We present the developed technique and test it on two sets of well logs collected from oil fields in offshore West Africa. The results give sensible well log blocking and resemble the original log curves reasonably well. Based on this fuzzy symbolic representation, an intelligent well logs interpretation system has been developed.

Intelligent reservoir characterization using seismic attributes and hydraulic flow units has a vital role in the description of oil and gas traps. The predicted model allows an accurate understanding of the reservoir quality, especially at the un-cored well location. This study was conducted in two major steps. In the first step, the survey compared different intelligent techniques to discover ...

Porosity is one of the fundamental petrophysical properties that should be evaluated for hydrocarbon bearing reservoirs. It is a vital factor in precise understanding of reservoir quality in a hydrocarbon field. Log data are exceedingly crucial information in petroleum industries, for many of hydrocarbon parameters are obtained by virtue of petrophysical data. There are three main petrophysical...
متن کاملImproving Petrophysical Interpretation of Conventional Log by Determination of Real Bed Boundaries
Proper determination of bed boundaries in layered reservoirs is vital for accurate petrophysical interpretation of conventional logs. In the wellbore, logs continuously measure physical properties of reservoir while the properties change stepwise. This continuous representation of logs may lead to ignorance of some high potential reservoir zones. The main reasons for continuous nature of l...

Well log data are routinely used for stratigraphic interpretation of the earth’s subsurface. This paper investigates using a co-evolutionary fuzzy system to generate a well log interpreter that can automatically process well log data and interpret reservoir permeability. The methodology consists of 3 steps: 1) transform well log data into fuzzy symbols which maintain the character of the origin...
متن کاملEvaluating Different Approaches to Permeability Prediction in a Carbonate Reservoir
Permeability can be directly measured using cores taken from the reservoir in the laboratory. Due to high cost associated with coring, cores are available in a limited number of wells in a field. Many empirical models, statistical methods, and intelligent techniques were suggested to predict permeability in un-cored wells from easy-to-obtain and frequent data such as wireline logs. The main obj...
