20080270152 | Patent Acquisition and Assertion by a (Non-Inventor) First Party Against a Second Party - Methods for a first party to acquire and assert a patent property against a second party are disclosed. The methods include obtaining an equity interest in the patent property. The methods further include writing a claim within the scope of the patent property. The claim is written to cover a product of the second party where the product includes a secret aspect. The methods further include filing the claim with a patent office. The methods sometimes include offering a license of the patent property to the second party after the patent property issues as a patent with the claim. The methods sometimes include asserting infringement of the claim by the second party after the patent property issues as a patent with the claim. The methods sometimes include negotiating a cross-license with the second party based on the assertion of infringement of the claim, where under the cross-license the first party obtains a license to an intellectual property right from the second party. The methods sometime include attempting to obtain a monetary settlement from the second party based on the assertion of infringement of the claim. | 10-30-2008 |
20100194588 | Telemetry System for Slickline Enabling Real Time Logging - A system for communicating with a slickline tool is disclosed.

20100262370 | Data Transmission Systems and Methods for Azimuthally Sensitive Tools with Multiple Depths of Investigation - Disclosed herein are various telemetry systems and methods suitable for communicating a cylindrical volume of formation property measurements to the surface. Some system embodiments include a downhole processor coupled to a telemetry transmitter. The downhole processor determines a compressed representation of the formation property measurements and/or selects a subset of the measurements for transmission uphole. The subset selection can be based on selected radial distances having characteristics that potentially indicate features of interest to a user. Such features include bed boundaries, and the characteristics include sinusoidal variation as a function of azimuth, large changes in this sinusoidal variation versus radial distance, or inversion suggesting the presence of a bed boundary. Various compressed representations of the cylindrical data volume are disclosed, including representations based on parameters of a sinusoidal model, representations based on a two dimensional transform, and representations based on estimates of distance and direction to a bed boundary. | 10-14-2010 |
20110234230 | Azimuthal At-Bit Resistivity and Geosteering Methods and Systems - Logging tools and methods employing an at-bit loop antenna to acquire azimuthal resistivity measurements proximate to the bit enable low-latency geosteering signals to be generated. In some embodiments, the at-bit antenna is part of a bottom hole assembly that includes a drill bit, a mud motor, and a resistivity tool. The mud motor is positioned between the at-bit antenna and the resistivity tool. The resistivity tool includes at least one loop antenna that is not parallel to the at-bit loop antenna. The at-bit antenna is part of an at-bit module that, in some embodiments, transmits periodic electromagnetic signal pulses for the resistivity tool to measure. In other embodiments, the at-bit module measures characteristics of electromagnetic signal pulses sent by the resistivity tool and communicates the measured characteristics to the resistivity tool via a short hop telemetry link. | 09-29-2011 |
20120133367 | Fracture Characterization Using Directional Electromagnetic Resistivity Measurements - A disclosed fracture characterization method includes: collecting three-dimensional resistivity measurements of a volume surrounding an open borehole; analyzing the measurements to determine parameters describing fractures in the volume; and providing a report to a user based at least in part on said parameters. A fluid with a contrasting resistivity is employed to make the fractures detectable by a directional electromagnetic logging tool in the borehole. illustrative parameters include fracture direction, height, extent, length, and thickness. The resistivity measurements can be augmented using a borehole wall image logging tool. Also disclosed are fracturing methods that include: positioning a directional electromagnetic logging tool proximate to a formation; fracturing the formation; monitoring fracture progression with said tool; and halting the fracturing when measurements by said tool indicate that a predetermined set of criteria have been satisfied. | 05-31-2012 |
