Abstract: An LCM recovery system that relies on gravity and density or specific gravity differences between three of the main components of drilling fluids, i.e., the mud and chemicals, lost circulation material (LCM) or additives, and drill solids or cuttings. Fluid enters the LCM recovery tank from the well via a flow line or mud gas separator return leg. Cuttings, having a greater density than additives, tend to settle and become trapped on the input side of the LCM recovery tank. The less dense fluid and entrained or suspended LCM tends to travel over the baffle near the center of the tank. LCM can then be efficiently returned to the active mud system for reconditioning or pumping downhole again.

Abstract: Method and apparatus for remotely controlling an instrument. In representative embodiments, at least one communication is received from each of at least two clients, wherein each received communication conforms to a client specific protocol. It is determined from which client each received communication was received. An application resident on the instrument for which each received communication is intended is determined, wherein at least one application is resident on the instrument. And each received communication is transferred to the intended application.

Abstract: An apparatus and method for obtaining a client program grammar communication from an Application Programming Interface (API) call. The API call is first obtained. When metadata is associated with the API call, the associated metadata is obtained and a best estimation of the client program grammar communication is obtained from the associated metadata and from the API call. Otherwise, a best estimation of the client program grammar communication is automatically obtained from the API call.

Abstract: A method for translating between Standard Commands for Programmable Instrumentation (SCPI) protocol and .NET protocol communications. When the communication from the client is a SCPI protocol command, it is converted to a .NET protocol command. The .NET protocol command is evaluated to determine the validity of the parameters sent from the client with the SCPI protocol command. Otherwise, when the communication is a SCPI protocol query from the client, the SCPI protocol query is converted to a .NET protocol query, and the .NET protocol query is evaluated to determine the validity of the parameters sent from the client with the SCPI protocol query. When the communication is intended for an instrument application, an appropriate Application Program Interface (API) responsive to method calls in the .NET protocol is then called.

Abstract: In an instrumentation system, the functionality of an I/O interface which controls an instrument is extended with an I/O interface extension library. The extension library operates to receive a function call and determines whether the function call is supported by the underlying I/O interface. If the function call is supported by the underlying I/O interface, the function call is passed on to the I/O interface for processing. If the function call is not supported by the underlying I/O interface, the function call is decoded into a sequence of standard I/O primitives that are supported by the underlying I/O interface, which are then sent on to the I/O interface for processing. In one embodiment, reduced overall latency time is achieved by packaging multiple sequential functions into a package and sending the package over an I/O bus to the instrument I/O controller as a single unit rather than sending each sequential function using separate bus instructions.
