Constrained Seismic Sequence Stratigraphy of Asmari - Kajhdumi interval with well-log Data
Sequence stratigraphy is a key step in interpretation of the seismic reflection data. It was originally developed by seismic specialists, and then the usage of high-resolution well logs and core data was taken into consideration in its implementation. The current paper aims in performing sequence stratigraphy using three-dimensional seismic data, well logs (gamma ray, sonic, porosity, density, ...
متن کاملThermal Conductivity from Core and Well log Data
The relationships between thermal conductivity and other petrophysical properties have been analysed for a borehole drilled in a Tertiary Flysch sequence. We establish equations that permit us to predict rock thermal conductivity from logging data. A regression analysis of thermal conductivity, bulk density, and sonic velocity yields thermal conductivity with an average accuracy of better than ...
متن کاملMind the Gap: A Well Log Data Analysis
The main task in oil and gas exploration is to gain an understanding of the distribution and nature of rocks and fluids in the subsurface. Well logs are records of petro-physical data acquired along a borehole, providing direct information about what is in the subsurface. The data collected by logging wells can have significant economic consequences, due to the costs inherent to drilling wells,...
متن کاملIntelligent Well Log Data Analysis: A Comparison Study
In this paper we compare three different soft computing methods used as the well log data analysis model in petroleum engineering. Due to the diversely behaving nature, namely, that each region has a unique geophysical characteristic it is difficult to build a universal model relating the mathematical behaviour of the measured variables. This is the reason why soft computing techniques may be f...
متن کاملHorizon refinement by synthesis of seismic and well log data
Subsurface rock strata are often conceptualized in three dimensions as depth surfaces, or horizons. By picking the corresponding reflection event from 3-D seismic data, an approximate “seismic horizon” can be obtained, but in general the inconsistencies in the approximation are nontrivial. Picks from well log data give the depth to the horizon to high accuracy, but only at a few points. To achi...
