20130124096 | Determining Drill String Status in A Wellbore - A method for determining a status of a drill string in a wellbore. The method can include obtaining pressure data and hook load data for the drill string. The pressure data can be filtered to obtain pressure sections. A low pressure threshold can be determined based upon the pressure sections. The hook load data can be filtered to obtain hook load sections. Hook load baselines can be determined based upon the hook load sections. Dynamic thresholds can be determined based upon the hook load baselines. An in-slips status of the drill string can be determined based upon the low pressure threshold, the dynamic thresholds, or both. | 05-16-2013 |
20140172306 | INTEGRATED OILFIELD DECISION MAKING SYSTEM AND METHOD - A method for controlling operations during construction of a subsurface wellbore includes measuring a plurality of wellbore construction parameters. At least one wellbore state parameter is calculated from the wellbore construction parameters in a computer. A plurality of users to communicate with the computer to enable access at least one of the measured wellbore construction parameters and the at least one wellbore state parameter. Depending on a assigned tasks, such user may receive task specific wellbore construction parameters and selected wellbore state parameters for display when a requested is communicated to the computer. | 06-19-2014 |
20150066371 | Integrated Oilfield Decision Making System and Method - A method for acquiring and processing wellbore measurements includes measuring at least one wellbore parameter. The measured wellbore parameters are communicated to a data hub. A computer in signal communication with the data hub automatically processes the measured wellbore parameter using a predefined automatic process. The automatically processed measured wellbore parameter is communicated to at least one user interface based on assigned tasks of a user interacting with the at least one user interface with respect to a wellbore construction procedure. | 03-05-2015 |
20150134257 | Automatic Wellbore Condition Indicator and Manager - A method for monitoring condition of a wellbore includes initializing a value of at least one parameter having a relationship to likelihood of a drill string becoming stuck in a wellbore (the HCF). During drilling operations, at least one drilling parameter having a determinable relationship to the HCF is measured. In a computer, the value of the HCF is recalculated based on the at least one measured parameter. The initial value of the HCF and the recalculated values of the HCF are displayed to a user. | 05-14-2015 |

20090194963 | Vehicle Suspension Assembly with Unique Geometry - A suspension system for supporting an axle and connected to a vehicle frame, including a pair of transversely spaced frame brackets mounted on and depending from the vehicle frame. Each of the frame brackets having one or more mounting points spaced along its perimeter for mounting of suspension components, such as shock absorbers, and having a protruding air spring attachment plate that extends inboard toward the center of the vehicle frame. The suspension system also includes a first pair of air springs, the upper portions of which are mounted to the air spring attachment plates of the frame brackets. The lower portions of the air springs are mounted to suspension arm. The suspension system includes a second pair of air springs that are longitudinally separated from the first pair of air springs and that are connected to the suspension arm assemblies and to the frame. A pair of shock absorbers is connected at their lowest point to the suspension arm assemblies and at their highest point to a mounting point on the frame brackets. The suspension arm assemblies are coupled to and support the axle. The suspension system also includes a torque box coupled to the vehicle frame and the axle. | 08-06-2009 |
20140042724 | Cylinder Shock Assembly - A cylinder shock assembly comprising a damper with a first end, and a second end that extends into an air cylinder float. The damper has a rod positioned in the air cylinder float with one end positioned within a cavity of the damper and another end affixed to an end cap attached to the air cylinder float. A primary coil spring is positioned within the air cylinder float, wherein when a load applied to the cylinder shock assembly is increased, an end of the damper move towards the end cap compressing air within the air cylinder float, wherein as the load is increased the primary coil spring is compressed and the volume of air within the air cylinder decreases resulting in an increased air pressure, and wherein the air cylinder float is a solid member that does not expand as the air pressure within increases during compression. | 02-13-2014 |
20140265205 | Vehicle Suspension - A suspension assembly having a frame hanger, a first control arm mounted between the frame hanger and an axle attachment member, a second control arm mounted to the frame hanger and to the axle attachment member, wherein the second arm extends from a centerline of the first control arm at an angle alpha such that the first control arm and the second control arm are not parallel to each other, wherein the centerline of the first control arm and the centerline of the second control arm extend to intersect at a point that is at a virtual center of rotation. | 09-18-2014 |
