An electronic device holder having a retention member for retaining an electronic device, such as an MP3 player, preferably an Apple® IPod nano having a multi-touch color screen, and a strap or shank attached to the retention member to allow fastening to an object, such as a user's wrist or a chain, is disclosed. The device may be secured by friction fitting into a recessed area having two ridges to engage the device along two edges. The device may be inserted by sliding or snap fitting into the recessed area. An opening along the back of the recessed area allows the device to be pushed laterally or vertically from the retention member. Alternatively, the retention member may be a two-piece frame which partially encloses the device. The frame pieces affix to either a wristband strap or a carabiner clip shank as they are secured to one another.

Electronic device holder

Methods and apparatus identify downhole equipment and correlate input data with the equipment to improve planning and/or inventory operations. For some embodiments, oilfield equipment or tubular goods such as drill pipe include a shaped recess along an outer circumference for receiving a tag cartridge by shrink fitting. Once tagged, detector system configurations at pipe yards may facilitate logging the presence and location of each drill pipe and correlating specific data, such as inspection data, to each drill pipe. Further, this correlation populates a database utilized to achieve other business functions such as forecasting number of additional drill pipe needed to purchase, invoicing customers according to actual tracked wear/use of the drill pipe being returned, and providing well or job specific drill string population using known history pipe joints.

Serialization and database methods for tubulars and oilfield equipment

An item (e.g. a drill bit) handling method, the item for use in a well operation, the method including producing information about an item used for a specific well task, the information including design information and intended use information, producing an item identification specific to the item, associating the information with the item identification producing thereby an information package, installing the information package in at least one wave-energizable apparatus, and applying the at least one wave-energizable apparatus to the item.

Systems and methods for monitored drilling

A completion apparatus for completing a wellbore includes a tool to alternatively open and close a throughbore; a tool to alternatively open and close an annulus between the outer surface of the completion and the inner surface of the wellbore; a tool to alternatively provide and prevent a fluid circulation route from the throughbore of the completion to the annulus; and at least one signal receiver and processing tool capable of decoding signals received. The apparatus is run into the well bore, the throughbore is closed and the fluid pressure in the tubing is increased to pressure test the completion; the annulus is closed and a fluid circulation route is provided from the throughbore to the annulus and fluid is circulated through the production tubing into the annulus and back to surface. The fluid circulation route is then closed and the throughbore is opened.

Method of and apparatus for completing a well

A system for separating components of a slurry is disclosed, the system including a housing; a basket for holding at least one shaker screen, the basket movably mounted in the housing; at least one vibrator coupled to the basket; a sump disposed below the basket to collect at least a portion of the slurry passing through the at least one shaker screen; a pressure differential device fluidly connected to the sump for developing a pressure differential across the at least one shaker screen; and a toggling device for toggling the pressure differential across the screen. A system including a degassing chamber fluidly connected to a sump and a pressure differential device, wherein the degassing chamber is disposed between the sump and the pressure differential device, and a fluid conduit fluidly connected to the degassing chamber for recovering a degassed fluid is also disclosed.

Shaker and degasser combination

A screen apparatus, which in certain aspects is a screen apparatus having a support, screening material on the support, and energizable identification apparatus on (exteriorly, interiorly, and/or within) the support for identifying the screen apparatus; a vibratory separator with such a screen apparatus; and a vibratory separator or shaker with energizable identification apparatus.

Shale shakers and screens with identification apparatuses

Methods for automatically controlling a vibratory separator, e.g., but not limited to a shale shaker for processing drilling fluid, the methods in certain aspects including: introducing material to a vibratory separator; sensing with sensor apparatus a state parameter indicative of operation of the vibratory separator; providing a signal indicative of a value of said state parameter to control apparatus; and, with the control apparatus, automatically controlling the vibratory separator based on the level of the state parameter. This abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims, 37 CFR 1.72(b).

Automatic vibratory separator

A vibratory separator (in one aspect, a shale shaker) and methods for using it, the separator in certain aspects having a base, a basket movably mounted on the base, screen apparatus on the basket, material flowing onto the screen apparatus for treatment, at least a portion of the screen apparatus not inclined downhill (e.g. said portion horizontal or uphill), electromagnetic vibratory apparatus connected to the basket for vibrating the basket and the screen apparatus, driving apparatus for driving the electromagnetic vibratory apparatus, and control apparatus (on-site and/or remote) for controlling the driving apparatus and the electromagnetic vibratory apparatus; the material, in one aspect, being drilling fluid material with solids therein.

Automatic separator or shaker with electromagnetic vibrator apparatus

A system for controlling viscosity of drilling fluid, the system, in certain aspects, including a container of the material, a viscosity sensor in the container for producing viscosity signals, a centrifuge for removing solids from the material, drive apparatuses for driving a rotatable bowl and a rotatable conveyor of the centrifuge, pump apparatus for pumping material, drive apparatus for the pump apparatus, and a control system for controlling the centrifuge and the pump apparatus in response to viscosity signals so that selected solids from material processed by the centrifuge are removed to control viscosity of drilling fluid material in the container; and in certain aspects, a similar system for controlling density of a drilling fluid material.

Centrifuge control in response to viscosity and density parameters of drilling fluid

Methods for automatically controlling a vibratory separator for processing drilling fluid are disclosed. The methods include introducing material to a vibratory separator,and sensing with a sensor apparatus a state parameter indicative of operation of the vibratory separator and providing a signal indicative of a value of the state parameter to a control apparatus. Then, with the control apparatus, automatically controlling the vibratory separator based on the level of the state parameter.In a further feature of a vibratory separator screen supports 310a, 311b, 311c are secured to their respective screens 310, 311, 312 with suitable clamping devices such as one or more electro-magnetic clamp apparatus 314, or other suitable clamp devices. The electro-magnetic clamp apparatus 314 may be of the type which are energized and/or de-energized with a single temporary electric pulse. That is, an un-magnetized clamp apparatus may be set to a magnetized state and remain in a magnetized state with a temporary electric pulse signal from some form of a controller device or other suitable source. Another pulse from the same or a different source may then set it back to an un-magnetized state and the clamp will remain in that state indefinitely until it is once again re-energized. The clamp apparatus may be based on monostable or bistable electropermanent magnets A 'constant 'G' force controller (not shown) may be included with the control system of the controller to assure that the vibratory accelerations are maintained within acceptable limits.
