Abstract: A series of jet nozzles have a telescoping structure designed to impact the borehole wall and initiate a fracture. The nozzles can be extended through fluid pumped through them or with some mechanical force from within the bottom hole assembly. The leading ends of the telescoping assembly can be sharp and hardened to facilitate the initiation of a formation fracture in an open hole. The telescoping structures can be disposed in a single or multiple rows with the circumferential spacing being such that each telescoping structure is designed to cover a target circumferential distance of 45 degrees or less so that jetted fluid from at least one jet will be within 22.5 degrees of a location of maximum formation stresses to reduce the tortuosity of the created fractures from jetting through the nozzles with possible enhancement of the fracturing from added annulus pressure.

Abstract: The invention provides a device for protecting ligaments in a knee joint of a user. The device includes a knee brace positionable about a knee joint of a user and a boot wearable on a foot of a user. Additionally, the device includes a flexible tether member including a first coupling element coupled to the knee brace and a second coupling element coupled to the boot. The boot and knee brace are attachable and detachable via the first and second coupling elements. The flexible tether member is adjustable in length to dispose the flexible tether member in tension at least in a portion of a maximum foot range of rotation, where the maximum foot range of rotation of the user's foot relative to the knee joint causes hyperextension of a knee ligament.

Abstract: A method and system for characterization of fault conditions within a subterranean volume. In one embodiment, the system comprises means for mathematically modeling stress conditions, to predict breakout conditions along a borehole trajectory. The system further comprises means for sensing actual breakout conditions along the borehole . Predictive breakout data is compared with sensed breakout conditions to assess correlation between predictive data and actual data, verifying the accuracy of the stress model. The mathematical model may be revised to reflect the presence of an active fault plane in the volume, the presumed fault plane not being intersected by the borehole. The revised model is used to generate new predictive data. Revising the stress model and assessing correlation between predictive and actual breakout conditions is repeatable to achieve an optimally accurate stress model reflecting fault conditions proximal to but not necessarily penetrated by the borehole.

Abstract: A system and method for the geomechanical steering of the orientation of a wellbore is disclosed. In one embodiment, any available a priori data regarding the stress characteristics of a region of interest are used to develop a preliminary stress model for the region. A geosteered drilling operation is thereafter commenced, with the trajectory being steered in a direction relative to the stress model of the region. While drilling, real-time data is obtained from conventional down-hole instrumentation. The real-time data is used to refine the stress model for the region, such that the trajectory can be guided on an ongoing basis to achieve an optimal relationship with the measured stress characteristics of the region.

Abstract: A method and system for characterization of fault conditions within a subterranean volume. In one embodiment, the system comprises means for generating a mathematical model of stress conditions within the volume, from which breakout conditions along a borehole trajectory can be predicted. The system further comprises means for sensing actual breakout conditions along a borehole extending through the volume. Predictive breakout data is compared with the actual sensed breakout conditions to assess the degree of correlation between the predictive data and the actual data, and thus the accuracy of the stress model. Means are provided for enabling a user to cause the mathematical model to be revised to reflect the presence of at least one active fault plane in the volume, where the presumed fault plane is not intersected by the borehole. The revised model is used to generate new predictive breakout data.

Abstract: There is provided a brace for stabilizing a uniting pivoting joint disposed between first and second limb structures of a living being. The brace comprises upper and lower frame members, each encompassing the first and second limb structures respectively, and a pivoting joint member comprised of two opposing pivoting assemblies. The assemblies include a limb extension slot having an adjustable length. The slot is located on at least one of the upper or lower frame members. The assemblies also include an exteriorly accessible limb extension regulator for regulating the limb extension slot length. The limb extension regulator is coupled to the limb extension slot. The pivoting assembly further includes an arm member comprised of upper and lower ends, each being pivotally connected to the upper and lower frame members, respectively. The arm member further includes a regulation portion retained in the limb extension slot.
