Heat flow and fluid flow regime in the western Nankai accretionary prism
The thermal structure of the western Nankai subduction zone has been studied through surface heat flow measurements with conventional geothermal probes and estimation of heat flow from depths of gas hydrate bottom simulating reflectors. Temperature and thermal conductivity measurements at ODP Site 808, located at the toe of the Nankai accretionary prism, added important information on any varia...
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...
متن کامل3D Petrophysical Modeling Usning Complex Seismic Attributes and Limited Well Log Data
A method for 3D modeling and interpretation of log properties from complex seismic attributes (obtained from 3D post stack seismic data) is developed by integrating Principal Component Analysis and Local Linear Modeling. Complex seismic attributes have non-linear relationships with petrophysical properties of rocks. These complicated relationships can be approximated using statistical methods. ...
متن کاملFluid Flow Property Estimation from Seismic Scattering Data
All geophysical methods detect fractures indirectly [e.g. NAS/NRC, 1996]. Typically several levels of interpretation follow the collection of raw geophysical data. Field measurements must first be interpreted (for example from travel time to velocities or identification of the origin of seismic scattering features in the coda). Then the fracture properties must be deduced using models (from sei...
متن کاملConstrained 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, ...
