Abstract
An automated method and system for determining the state of a drilling or other suitable well operations includes storing a plurality of states for the well operation. Mechanical and hydraulic data is received for the well operation. Based on the mechanical and hydraulic data, one of the states is automatically selected as the state of the well operation. Process evaluation may be performed based on the state of the well operation.
Claims115
An automated method for determining the state of a well operation, comprising:
- storing a plurality of states for a well operation;
- receiving mechanical and hydraulic data reported for the well operation from a plurality of systems;
- and
- determining that at least some of the data is valid by comparing the at least some of the data to at least one limit, the at least one limit indicative of a threshold at which the at least some of the data do not accurately represent the mechanical or hydraulic condition purportedly represented by the at least some of the data;
- and
- when the at least some of the data are valid, based on the mechanical and hydraulic data, automatically selecting one of the states as the state of the well operation.
An automated system for determining the state of a well operation comprising:
- means for storing a plurality of states for a well operation;
- means for determining that at least some received mechanical and hydraulic data is valid by comparing the at least some of the data to at least one limit, the at least one limit indicative of a threshold at which the at least some of the data does not accurately represent the mechanical or hydraulic condition purportedly represented by the at least some of the data;
- and
- means for automatically selecting one of the states based on mechanical and hydraulic data as the state of the well operation when the at least some of the mechanical and hydraulic data are valid.
An automated system for determining the state of a well operation, comprising:
- logic encoded in media;
- and
- the logic operable to receive mechanical and hydraulic data reported for the well operation from a plurality of systems, determine that at least some of the received data is valid by comparing the at least some of the received data to at least one limit, the at least one limit indicative of a threshold at which the at least some of the received data do not accurately represent the condition purportedly represented by the at least some of the received data, and to automatically select one of the states as the state of the well operation based on the mechanical and hydraulic data when the at least some of the received data are valid.
An automated method for determining a state of a drilling operation comprising:
- receiving mechanical and hydraulic data reported for a drilling operation;
- based on the mechanical and hydraulic data, determining a state of the drilling operation;
- wherein the state of the drilling operation is determined to be:
- drilling if:
- a hole is being made;
- or
- a hole is not being made, a drill bit associated with the drilling operation is on bottom and drilling fluid associated with the drill bit is circulating;
- testing/conditioning if:
- a hole is not being made, the drill bit is on bottom and the drilling fluid is not circulating;
- or
- a hole is not being made, the drill bit is off bottom and the drill bit has a constant position;
- and
- tripping/reaming if:
- a hole is not being made, the drill bit is off bottom and the position of the drill bit is not constant.
The method of claim, 91, wherein the state of the drilling operation is determined to be in slips if a hole is not being made, the drill bit is off bottom, the drill bit has a constant bit position and a hook load associated with the drilling operation is substantially equal to a block weight associated with the drilling operation.
An automated method for determining the state of a well operation, comprising:
- storing a plurality of states comprising at least a productive and a non-productive state for the well operation;
- receiving mechanical and hydraulic data reported for the well operation;
- and
- determining that at least some of the data is valid by comparing the data to at least one limit, the at least one limit indicative of a threshold at which the at least some of the data do not accurately represent the mechanical or hydraulic condition purportedly represented by the at least some of the data;
- and
- when the at least some of the data are valid, based on the mechanical and hydraulic data, automatically selecting one of the plurality of states as the state of the well operation.
An automated system for determining the state of a well operation, comprising:
- logic encoded in media;
- and
- the logic operable to receive mechanical and hydraulic data reported for the well operation, determine that at least some of the received data is valid by comparing the data to at least one limit, the at least one limit indicative of a threshold at which at least some of the data do not accurately represent the condition purportedly represented by the at least some of the received data, and to automatically select one of a productive state and a non-productive state as a state of the well operation based on the mechanical and hydraulic data when the at least some of the received data are valid.
