Patent number: 8698502Abstract: A method for analyzing a subterranean formation porosity is disclosed. The apparent dielectric constant of the subterranean formation and an apparent resistivity of the subterranean formation are measured. The measured values are used to determine a measured formation loss tangent. The formation water loss tangent can be expressed by the water dielectric constant and the water resistivity. The measured formation loss tangent and the formation water loss tangent are then used to determine at least one of an actual dielectric constant of the subterranean formation water and an actual resistivity of the subterranean formation water. The actual formation porosity may be obtained using the estimated water resistivity and water dielectric constant.Type: GrantFiled: September 21, 2012Date of Patent: April 15, 2014Assignee: Halliburton Energy Services, Inc.Inventors: Jing Li, Gary Kainer, Marvin Rourke, Michael Bittar

Publication number: 20080078580Abstract: Systems and methods for performing bed boundary detection and azimuthal resistivity logging with a single tool are disclosed. Some method embodiments include logging a borehole with an azimuthally-sensitive resistivity logging tool; deriving both a resistivity log and a boundary detection signal from measurements provided by said tool; and displaying at least one of the boundary detection signal and the resistivity log. The resistivity log measurements may be compensated logs, i.e., logs derived from measurements by one or more symmetric transmitter-receiver arrangements. Though symmetric arrangements can also serve as the basis for the boundary detection signal, a greater depth of investigation can be obtained with an asymmetric arrangement. Hence the boundary detection signal may be uncompensated.Type: ApplicationFiled: August 8, 2007Publication date: April 3, 2008Applicant: Halliburton Energy Services, Inc.Inventor: Michael Bittar

Publication number: 20070235225Abstract: This invention is directed to a downhole method and apparatus for simultaneously determining the horizontal resistivity, vertical resistivity, and relative dip angle for anisotropic earth formations. The present invention accomplishes this objective by using an antenna configuration in which a transmitter antenna and a receiver antenna are oriented in non-parallel planes such that the vertical resistivity and the relative dip angle are decoupled. Preferably, either the transmitter or the receiver is mounted in a conventional orientation in a first plane that is normal to the tool axis, and the other antenna is mounted in a second plane that is not parallel to the first plane. This invention also relates to a method and apparatus for steering a downhole tool during a drilling operation in order to maintain the borehole within a desired earth formation.Type: ApplicationFiled: May 8, 2007Publication date: October 11, 2007Applicant: HALLIBURTON ENERGY SERVICES, INC.Inventor: Michael Bittar
