Patent number: 10513920Abstract: A method of performing an operation in a wellbore includes performing the operation in the wellbore from a rig; and, while performing the operation, repeatedly: inputting one or more predicted values from a model of the wellbore; inputting one or more measured parameters from one or more sensors of the rig; calculating a deviation of each measured parameter from a respective predicted value; applying a weighting factor to each calculated deviation to obtain a respective alert level; calculating a rate of change of each measured parameter from a parameter previously measured by the respective sensor; applying a weighting factor to each calculated rate of change to obtain a respective alert level; and adding the alert levels and dividing the sum thereof by a maximum alert level to obtain a stuck pipe risk.Type: GrantFiled: January 27, 2016Date of Patent: December 24, 2019Assignee: WEATHERFORD TECHNOLOGY HOLDINGS, LLCInventors: Kent Patrick Salminen, Curtis Alan Cheatham, Mark Adrian Smith

Publication number: 20170150797Abstract: A hair care appliance comprising a body having an outer wall, a chassis extending within the outer wall, wherein the chassis comprises a locking feature and the body comprises an engaging feature adapted to retain the chassis in position within the outer wall when the locking feature is rotated with respect to the engaging feature. The outer wall may comprise an inner surface and the engaging feature extends radially inwards from the inner surface. The engaging feature may comprise a rib that extends from an inner surface of the outer wall. The engaging feature may extend at least partially around the inner surface of the outer wall. The engaging feature may comprise a pair of engaging features which may be radially spaced apart. The locking feature may comprise a locking rib which may extend radially from the chassis towards the outer wall.Type: ApplicationFiled: November 22, 2016Publication date: June 1, 2017Applicant: Dyson Technology LimitedInventors: Nathan Haruna Waters IMHASLY, Stephen Farrar SMITH, Philip Jonathan STEPHENS, Mark Adrian SMITH

Publication number: 20160235178Abstract: A hand held appliance comprising a body, a handle having a first end connected to the body and a second end distal to the first end, an end wall extending across the handle at the second end of the handle wherein said end wall is detachable from the handle and a filter is provided within the handle. The end wall may include a plurality of apertures which may comprise a fluid inlet into the appliance. The end wall may be flexible and may be made from a plastic material such as polypropylene and ABS. The end wall may comprise a rim and a lip extending radially inwards of the rim.Type: ApplicationFiled: September 18, 2014Publication date: August 18, 2016Applicant: Dyson Technology LimitedInventors: Antoine Francois ATKINSON, Lyndsey Gelia HYLBERT, Thomas James KERR, Mark Adrian SMITH

Patent number: 8417456Abstract: Downhole drilling vibration analysis uses acceleration data measured in three orthogonal axes downhole while drilling to determine whether drilling assembly's efficiency has fallen to a point where the assembly needs to be pulled. In real or near real time, a downhole tool calculates impulse in at least one direction using the measured acceleration data over an acquisition period and determines whether the calculated impulse exceeds a predetermined acceleration threshold for the acquisition period. If the impulse exceeds the threshold, the tool pulses the impulse data to the surface where the calculated impulse is correlated to efficiency of the assembly as the drillstring is used to drill in real time. Based on the correlation, operators can determine whether to pull the assembly if excessive impulse occurs continuously over a predetermined penetration depth.Type: GrantFiled: July 27, 2012Date of Patent: April 9, 2013Assignee: Precision Energy Services, Inc.Inventors: Charles Lee Mauldin, Barry Vincent Schneider, Mark Adrian Smith
