Predicting stress-induced anisotropy around a borehole
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
Formation elastic properties near a borehole may be altered from their original state due to the stress concentration around the borehole. This could result in a biased estimation of formation properties but could provide ...
Multipole seismoelectric logging while drilling (LWD) for acoustic velocity measurements
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
In seismoelectric well logging, an acoustic wave propagates along a borehole and induces electrical signals along the borehole wall. The apparent velocities of these seismoelectric signals are equal to the formation ...
Integration of Geology, Rock-Physics, Logs, and Pre-stack Seismic for Reservoir Porosity Estimation
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2011)
The main objective of this paper is to obtain reservoir properties, such as porosity, both at the well locations and in the inter-well regions from seismic data and well logs. The seismic and well-log datasets are from an ...
3-D Geostatistical Seismic Inversion With Well Log Constraints
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2000)
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 ...
Model-guided Geosteering for Horizontal Drilling
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2009)
Horizontal drilling is an important development in the petroleum industry and it relies
heavily on guiding the drill bit with the aid of sonic logging, i.e. geosteering. The quality
of sonic imaging depends heavily on ...
Geostatistical Seismic Inversion Using Well Log Constraints
(Massachusetts Institute of Technology. Earth Resources Laboratory, 1999)
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 ...
An approach for predicting stress-induced anisotropy around a borehole
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
Formation elastic properties near a borehole may be altered from their original state due to the stress concentration around the borehole. This could result in a biased estimation of formation properties but could provide ...
Effect of borehole stress concentration on compressional wave velocity measurements
(Massachusetts Institute of Technology. Earth Resources Laboratory, 2013)
Formation elastic properties near a borehole may be altered from their original state due to the stress concentration around the borehole. This could lead to a biased estimation of formation elastic properties measured ...
