Abstract
Methods, computer programs, and systems for detecting at least one downhole condition are disclosed. Forces are measured at a plurality of locations along the drillstring. The drillstring includes a drillpipe. At least one of the forces is measured along the drillpipe. At least one downhole condition is detected based, at least in part, on at least one measured force.
Claims39
A method of analyzing one or more downhole properties, comprising:
- receiving a plurality of force measurements, each corresponding to a location along a drillstring, the drillstring comprising a drillpipe, and where at least one force measurement corresponds to a location along the drillpipe;
- performing at least one action based, at least in part, on the at least one force measurement;
- wherein at least one of the force measurements comprise at least one of a torque measurement or a tensile force measurement.
A measurement-while-drilling system for collecting and analyzing one or more force measurements, comprising:
- a plurality of force sensors to measure forces at a drillstring, where at least one force sensor is located along a drillpipe;
- a processor;
- and
- a memory, the memory including executable instructions that, when executed, cause the processor to:
- cause at least one additional action to be performed based, at least in part, on at least one measured force;
- wherein at least one of the force measurements comprise at least one of a torque measurement or a tensile force measurement;
- and
- wherein at least one of the force sensors is coupled to the processor.

A method comprising:
- receiving a plurality of force measurements, each corresponding to a location along a drillstring, the drillstring comprising a drillpipe, and where at least one force measurement corresponds to a location along the drillpipe;
- displaying at least one graphical representation of one or more of the received plurality of force measurements;
- wherein at least one of the force measurements comprise at least one of a torque measurement or a tensile force measurement.
A method of analyzing one or more downhole properties, comprising:
- receiving a plurality of force measurements, each corresponding to a location along a drillstring, the drillstring comprising a drillpipe, and where at least one force measurement corresponds to a location along the drillpipe;
- providing an indication to an operator based, at least in part, on the at least one force measurement;
- wherein at least one of the force measurements comprise at least one of a torque measurement or a tensile force measurement.
A method comprising:
- receiving a first plurality of force measurements, each force measurement corresponding to a location along a drillstring, the drillstring comprising a drillpipe, and where at least one force measurement corresponds to a location along the drillpipe;
- creating a first measured-value set comprising the first plurality of force measurements and corresponding depths;
- receiving a second plurality of force measurements taken at a different time from the first plurality of force measurements, each force measurement corresponding to a location along a drillstring;
- creating a second measured-value set comprising the second plurality of force measurements and corresponding depths;
- and
- creating a representation for an operator of both the first measured value set and the second measured-value set.
