Automated Method And System For Determining The State Of Well Operations And Performing Process Evaluation
View pageUS Patent:
6892812, May 17, 2005
Filed:
May 21, 2002
Appl. No.:
10/153845
Inventors:
Michael Niedermayr - Stafford TX, US
Mitchell D. Pinckard - Houston TX, US
Gerhard P. Glaser - Houston TX, US
Mitchell D. Pinckard - Houston TX, US
Gerhard P. Glaser - Houston TX, US
Assignee:
Noble Drilling Services Inc. - Sugar Land TX
International Classification:
E21B044/00
US Classification:
16625015, 166 53, 175 24, 175 40, 702 9
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.
System And Method For Automatic Drilling To Maintain Equivalent Circulating Density At A Preferred Value

7044239, May 16, 2006
Filed:
Apr 25, 2003
Appl. No.:
10/423724
Inventors:
Mitchell D. Pinckard - Houston TX, US

International Classification:
E21B 19/08
E21B 44/06
E21B 44/06
US Classification:
175 57, 175 24, 175 27, 175 38, 175 48
Abstract:
A drilling system includes a pressure sensor disposed on a drill string in the wellbore, the sensor responsive to pressure of a drilling fluid disposed in an annular space between a wall of the wellbore and the drill string, and a processor operatively coupled to the pressure sensor. The processor is adapted to operate a drill string release controller to release the drill string into the wellbore so as to maintain an equivalent density of the drilling fluid substantially at a selected value. A method for automatically drilling a wellbore includes measuring pressure of a drilling fluid in an annular space between a wall of the wellbore and a drill string in the wellbore, and automatically controlling a rate of release of the drill string in response to the measured pressure so as to maintain an equivalent density of the drilling fluid substantially at a selected value.

International Classification:
E21B019/08
US Classification:
175/038000, 175/048000
Abstract:
An automated method and system for recognizing a well control event includes determining a state of drilling operations. When drilling operations are in a circulating state, a benchmark for a relative flow value. The relative flow value is based on a flow of drilling fluid into a well bore and a flow of drilling fluid out of the well bore. A limit on variation of the relative flow value is determined from the benchmark. A cumulative sum for the relative flow value is determined over time in response to the relative flow value exceeding the limit. A well control event is recognized based on the cumulative sum.
