Resistivity data ahead of the bit is gathered during drilling and prior to penetrating a region of interest of a target subterranean formation using the drill bit and the drilling mud. The drill string progresses at target dip and azimuth angles toward the region on interest. The resistivity data is used to determine the top of the region of interest while the drill bit advances toward but does not penetrate the region. A core bit is then installed and a whole core of the region of interest obtained. Resistivity ahead of a drill bit measurements obtained while drilling a subterranean well may also be compared with conventional resistivity measurements obtained from one or more offset wells.

  • Patent number: 7546209
    Abstract: A method of drilling a well. The method includes calculating an estimated formation dip angle, wherein said estimated formation dip angle being based on offset well data, seismic data, core data, pressure data. Next, the method includes drilling a well with a logging while drilling means so that real time logging data is generated along with drilling data and calculating an instantaneous formation dip angle. Next, real time logging data is obtained and a target formation window is projected ahead of the well path that includes a top of formation and a bottom formation. The method includes monitoring the real time logging and drilling data and drilling the well through the target formation window. The method further includes changing the estimated instantaneous formation dip based on the obtained data and adjusting the target formation top and bottom window.

  • Publication number: 20090120637
    Abstract: A system for positioning a wellbore tool in a wellbore intersecting a subterranean formation includes a tag embedded in the formation using a tag insertion device. The tag may be configured to transmit a signal that includes information. A wellbore tool may utilize a tag detection device to operatively link with the tag. This operative link may provide an indication of the relative position of the tag detection device or some other information.

  • Patent number: 7299884
    Abstract: Measurements are made continuously with a seismic while drilling (SWD) system and the measured data are stored in a working memory of a downhole processor along with quality control (QC) measurements. The QC data are analyzed and based on the analysis, portions of the data in working memory are recorded in permanent memory for retrieval. Alternatively, QC measurements are made substantially continuously predictions are made when data quality for SWD measurements are likely to be good. Recording of SWD data are then started based on the prediction.
