Geostatistical Seismic Inversion Using Well Log Constraints
Information about reservoir properties usually comes from two sources: seismic data and well logs. The former provide an indirect, low resolution image of rock velocity and density. The latter provide direct, high resolution (but laterally sparse) sampling of these and other rock parameters. An important problem in reservoir characterization is how best to combine these data sets, allowing the ...
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 کاملFramework for time lapse fracture characterization using seismic, microseismic & well log data
Extensive work has been done in the recent years involving use of conventional and passive seismic data for fracture characterization. This is particularly the case with unconventional reservoirs such as shale gas, shale oil and geothermal fields. The purpose of our study is to combine the benefits of conventional seismic data that provides relatively higher resolution reservoir characteristics...
متن کاملSPE 154339 Reservoir Characterization of an Unconventional Reservoir by Integrating Microseismic, Seismic, and Well Log Data
Varied data types including geophysical data as well as well logs have been used frequently in the past to characterize reservoirs. However, the use of microseismic data as a potential source of useful information and its integration with conventional seismic data for reservoir characterization is an area of opportunity where properties predicted from the microseismic data can be used as a vita...
متن کاملSeismic and Magneto-telluric Imaging for Geothermal Exploration at Jemez Pueblo in New Mexico
A shallow geothermal reservoir in the Pueblo of Jemez in New Mexico may indicate a commercialscale geothermal energy potential in the area. To explore the geothermal resource at Jemez Pueblo, seismic surveys are conducted along three lines for the purpose of imaging complex subsurface structures near the Indian Springs fault zone. A 3-D magneto-telluric (MT) survey is also carried out in the sa...
