Abstract: To reduce the expense associated with having experts work at remote hydrocarbon recovery, exploration, operation, or services environment site, such experts may use a virtual real time operation center to obtain information from and give instructions to the remote site. Such a virtual operation center may receive information from the site from a variety of different machines such as equipment pieces, controllers, or human machine interface personal computers.

Abstract: A virtual presence may be established to provide engagement with equipment and operators at a hydrocarbon recovery, exploration, operation, or services environments in order to reduce the expense associated with having knowledge experts, or other personnel, travel to and work at remote hydrocarbon recovery, exploration, operation, or services environments. For example, a wearable device may allow a user, such as a subject matter expert, at a virtual real time operation center to view data from equipment located at the site.

Abstract: To reduce costs and improve efficiency: of one or more operations associated with a hydrocarbon recovery, exploration, operation or services site, a control system utilizes one or more sensors to obtain real-time data associated with one or more pieces of equipment at one or more sites, utilizes one or more audio-visual devices to provide one or more notifications based, at least in part, on the real-time data, utilizes one or more control devices to produce one or more commands based, at least in part, on the one or more notifications, and utilizes a network, system to provide the one or more commands to one or more pieces; of equipment at the one or more sites to control the one or more pieces of equipment Farther, a method is presented for collecting real-time data, providing notifications from an audiovisual device based, at least in part, on the on-site data associated with one or snore pieces of equipment at one or more sites, generating a command from, a control device, providing the command to one or

Abstract: A cementing system having an engine control module, a transmission control module, a computing device and a display. The engine control module communicatively coupled with a plurality of engine sensors. The transmission control module communicatively coupled with a plurality of transmission sensor. The computing device is communicatively coupled with the display and communicatively coupled, via at least one J1939 data link, with the engine control module and the transmission control module. The computing device is configured to receive data from at least one of an engine control module or a transmission control module, compare the received data to a list of stored codes and in response to the received data matching a stored code, causing the rendering of an alarm message associated with the matched code and/or a warning message associated with the matched code on the display.

Abstract: A method of servicing a request during high pressure wellsite pumping operations to manipulate a valve in a manifold system having a plurality of valves includes receiving a plurality of valve configurations that would result in an overpressured manifold system and comparing the request to a proposed valve configuration that would result from a proposed valve manipulation. The method includes determining whether a pump to the manifold system is operating. The method further includes determining whether the proposed valve manipulation inhibits a flow path between the pump and an outlet of the manifold system and would result in an overpressured manifold system. The method also includes in response to a determination that the proposed valve manipulation inhibits the flow path: blocking the proposed valve manipulation and presenting an operator with an override option.

Abstract: A cementing system is provided. A cement slurry dispenser includes at least one control valve, at least one liquid additive pump, and at least one water pump. A computer has a display for an interface screen. The e interface screen displays a list zone of available selectable tests for the cement slurry dispenser and corresponding global selection choices, a detail zone, wherein in response to selection of one of the selectable tests from the list zone, substeps of the selected one of the selectable tests is displayed a local activate button configured to commence only the selected one of the selectable tests displayed in the detail zone; and a global activate button configured to commence all of the selectable tests in the list zone that are indicated as selected by the corresponding global selection choices. The computer implements the tests on the cement slurry dispenser.
