Well construction display

Abstract

A method for steering a downhole tool in a wellbore includes measuring a tool face when the drill bit is off-bottom, measuring an angular position of a drill string when the drill bit is off-bottom, and measuring a torque on the drill string when the drill bit is off-bottom. The method also includes measuring the tool face when the drill bit is on-bottom and measuring the torque on the drill string when the drill bit is on-bottom. The method also includes determining a transfer function comprising the angular position of the quill, the difference between the toolface when the drill bit is on-bottom and off-bottom, and the difference between the torque when the drill bit is on-bottom and off-bottom. The angular position of the drill string is varied at the surface, based upon the transfer function, to reduce an angle between the tool face when the drill bit is on-bottom and a target tool face.

What is claimed is: 
     
         1 . A well construction display, comprising:
 a first sensor positioned at a surface location proximate to a wellbore;   a second sensor positioned within the wellbore; and   a well construction engine configured to receive data from the first and second sensors, wherein, in response to the data, the well construction engine is configured to determine a state of wellsite equipment, a state of well construction, a drilling event, a well event, or a combination thereof.   
     
     
         2 . The well construction display of  claim 1 , further comprising a display configured to show an equipment-human-machine interface that is used to control the wellsite equipment or to alter one or more drilling process parameters. 
     
     
         3 . The well construction display of  claim 2 , wherein the equipment-human-machine interface is also configured to control parameter setpoints that are activated to generate the commands for operation of the wellsite equipment. 
     
     
         4 . The well construction display of  claim 2 , wherein the wellsite equipment is controlled to alter the one or more drilling process parameters. 
     
     
         5 . The well construction display of  claim 2 , wherein the display is configured to show the data from the first and second sensors. 
     
     
         6 . The well construction display of  claim 5 , further comprising a video camera, wherein the display is configured to show a video stream from the video camera. 
     
     
         7 . The well construction display of  claim 2 , wherein the display is configured to show information based on a user's role.
