    • 3-D Geostatistical Seismic Inversion With Well Log Constraints 

      Kane, Jonathan; Rodi, William; Toksoz, M. Nafi (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 ...
    • An approach for predicting stress-induced anisotropy around a borehole 

      Fang, Xinding; Fehler, Michael; Zhu, Zhenya; Chen, Tianrun; Brown, Stephen; e.a. (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 

      Fang, Xinding; Fehler, Michael; Cheng, Arthur (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 ...
    • Geostatistical Seismic Inversion Using Well Log Constraints 

      Kane, Jonathan; Rodi, William; Herrmann, Felix; Toksoz, M. Nafi (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 ...
    • Integration of Geology, Rock-Physics, Logs, and Pre-stack Seismic for Reservoir Porosity Estimation 

      Al Muhaidib, Abdulaziz; Sen, Mrinal K.; Toksoz, M. Nafi (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 ...
    • Model-guided Geosteering for Horizontal Drilling 

      Song, Fuxian; Toksoz, M. Nafi (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 ...
    • Multipole seismoelectric logging while drilling (LWD) for acoustic velocity measurements 

      Zhu, Zhenya; Wang, Jun; Toksoz, M. Nafi (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 ...

      Fang, Xinding; Fehler, Michael; Zhu, Zhenya; Chen, Tianrun; Brown, Stephen; e.a. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2012)
