20130043168 | MAGNETIC VIBRATORY SCREEN CLAMPING - The present disclosure is generally directed to vibratory separators that are used for processing drilling fluid, and in particular, vibratory separators that utilize electromagnetic clamping apparatuses for attaching screen assemblies to a basket assembly. In one exemplary embodiment, an illustrative vibratory separator is disclosed which includes, among other things, a basket assembly having at least one screen support, and at least one screen assembly that is adapted to be releasably secured to the at least one screen support. Additionally, the disclosed vibratory separator also includes an electromagnetic clamp apparatus that is adapted to releasably secure the at least one screen assembly to the at least one screen support when the electro-magnetic clamp apparatus is energized to a magnetized state, and to release the at least one screen assembly from the at least one screen support when the electro-magnetic clamp apparatus is de-energized to an un-magnetized state. | 02-21-2013 |
20130112486 | Resilient Bit Systems and Methods - A drill bit for subsurface drilling includes a body, a blade extending from the body, and a flex cut behind the front side of the blade to allow at least a portion of the blade to flex. The drill bit may include a void cut disposed behind the front side of the blade and intersecting the flex cut. A void cut is larger in one dimension than is the flex cut in that dimension. | 05-09-2013 |
20130118812 | Rotary Steerable Push-the-Bit Drilling Apparatus with Self-Cleaning Fluid Filter - A steerable drilling apparatus includes a control system inside a cylindrical housing connected to a drill bit having radially-extendable pistons. A fluid-metering assembly directs a piston-actuating fluid into fluid channels leading to respective pistons. The control system controls the fluid-metering assembly to allow fluid flow to selected pistons, causing the actuated pistons to temporarily extend in the opposite direction to a desired wellbore deviation, thereby deflecting the drill bit away from the borehole centerline. An upper member in the fluid-metering assembly can be moved to stabilize, steer, and change TFA within the drill bit. The control system and drill bit are connected so as to facilitate removal to change the drill bit's steering section and cutting structure configuration or gauge simultaneously. The apparatus may incorporate a fluid filter module mounted to the control system. The pistons may incorporate auxiliary cutting elements to provide near-bit reaming capability. | 05-16-2013 |
20130142977 | Releasable Corrosion Inhibitors - The present invention includes compositions and methods of supplying a corrosion inhibitor including placing a corrosion inhibitor attached to a nanostructure carrier, placing the nanostructure carrier containing the corrosion inhibitor at a location and the nanostructure carrier is capable of releasing the corrosion inhibitor. | 06-06-2013 |
20130146359 | METHOD AND SYSTEM FOR MONITORING A WELL FOR UNWANTED FORMATION FLUID INFLUX - A method of monitoring a well for unwanted formation fluid influx is disclosed. Measurements of well outflow are acquired during a period in which drilling operations are performed for the well. Occurrences of stagnant flow events during the period are determined. An outflow signature is generated from the well outflow measurements for each stagnant flow event. The outflow signatures are displayed sequentially in time of occurrence. Each outflow signature is analyzed for an anomaly. | 06-13-2013 |
20130160309 | SYSTEM AND METHOD FOR MEASURING PIPE - A system and method for measuring a pipe is provided. The system includes a frame rotatably receiving the pipe, a carriage movably positionable along the frame, a guide floatingly positionable about the carriage, at least one sensor for measuring a position of the pipe, and a measurement unit operatively linked to the sensor for collecting measurements therefrom. The guide has a mouth that receivingly engages the pipe and axially aligns therewith. The pipe is measured with the sensor(s) while moving at least one of the pipe, the carriage and the guide. | 06-27-2013 |
20130161029 | HYDRODYNAMIC JOURNAL BEARING FLOW CONTROL BUSHING FOR A ROTATING CONTROL DEVICE - A rotating control device comprises an outer housing having a bore for receiving a tubular member. An inner housing and a piston assembly are rotatably disposed within the outer housing. An annular sealing assembly is disposed between the piston assembly and the inner housing so that axial movement of the piston assembly moves the annular sealing assembly into sealing engagement with the inner housing and the tubular member. A plurality of bearings is disposed between the inner housing and the outer housing. At least one of the plurality of bearings is a hydrodynamic journal bearing. | 06-27-2013 |
20130168345 | DEEP WATER KNUCKLE BOOM CRANE - A crane including an inner boom, an outer boom, a plurality of guide assemblies arranged along the length of the inner and outer boom and adapted for guiding a plurality of lines, and a multi-line material handling system including a first line having an outgoing portion extending to a sheave block, and an incoming portion returning from the sheave block to a supported anchor device, and a second line having an outgoing portion extending to the sheave block, and an incoming portion returning from the sheave block to the supported anchor device. | 07-04-2013 |
20130168516 | Apparatus and Method for Positioning Connection Equipment on a Drilling Rig - A positioning apparatus for moving connection equipment on a drilling rig, the positioning apparatus comprising a piston and cylinder ( | 07-04-2013 |
20130180186 | COLLAPSIBLE SUBSTRUCTURE FOR A MOBILE DRILLING RIG - Generally, the present disclosure is directed to a collapsible substructure of a mobile drilling rig. In one illustrative embodiment, a drilling rig substructure is disclosed that includes a base having a fixed drill floor mounted thereon, wherein an upper surface of the fixed drill floor is positioned at an operating height above the base for performing drilling operations at a wellbore location of a drilling site. Furthermore, a raisable floor is also included that is adapted to be positioned in a lowered transportation position for transportation of the substructure to the drilling site and raised to an operating position adjacent to the fixed drill floor for performing drilling operations, wherein a height level of an upper surface of the raisable floor is lower than a height level of the upper surface of the fixed drill floor when the raisable floor is positioned in the lowered transportation position. | 07-18-2013 |
20130186689 | DOWNHOLE TOOL WITH EXTERNAL HOUSING TORQUE TRANSFER - A downhole tool comprises a first connector sub coupled to an outer housing. A mandrel is disposed in the outer housing and is coupled to a mandrel. The second connector sub is slidably engaged with the outer housing so that torque loads are transferred from the first connector sub to the second connector sub through the outer housing independently of the mandrel. | 07-25-2013 |
