摘要:
Methods of initiating a fracture tip screenout, that comprise pumping an annulus fluid into an annulus, between the subterranean formation and a work string disposed within a wellbore penetrating the subterranean formation, at an annulus flow rate; and reducing the annulus flow rate below a fracture initiation flow point so that the fracture tip screenout is initiated in the one or more fractures in the subterranean formation, are provided. Also provided are methods of fracturing a portion of a subterranean formation and methods of estimating a fracture initiation flow point.

According to one embodiment of the invention, a flow conditioning system for fluid jetting tools includes a housing having a plurality of jet nozzle openings and a fluid straightener disposed within the housing. The fluid straightener is defined by one or more vanes, and the vanes form a plurality of flow channels within the housing. Each flow channel is associated with at least one jet nozzle opening.

The invention provides a method of transitioning between voice and data communications with a mobile vehicle. A switch-to-voice command signal is sent from a call center modem pool to the mobile vehicle, and a vehicle switch-to-voice acknowledgement signal is received at the call center. A call from the call center modem pool is switched to a call center advisor in response to the vehicle switch-to-voice acknowledgement signal.

An automatic lighted level and a angle finder has a frame provided with a planar surface arranged for abutting against an object the orientation of which is to be determined or adjusted. An electrically energized visual indicator is mounted in the frame of the device for indicating when the planar surface of the frame is oriented at a predetermined angle by the closing of an angle-sensing switch including a reel assembly adjustably mounted in an opening provided in the frame and connected to the indicator and to a source of electrical power for energizing the indicator by closing an electrical circuit connecting the indicator to the source of electrical power when the switch is rotated relative to the frame to an angle corresponding to the angle of an object whose angular orientation is being determined. Alternatively, the planar surface may be placed on the object and the latter moved until its orientation corresponds to a predetermined angle set on the switch. A circular scale graduated in degrees cooperating with a pointer provides a visual indication of the angular setting of the switch.

A gas burner of a household cooking appliance is provided. The gas burner includes a burner portion, and a pedestal portion under the burner portion for elevating the burner portion above a cooktop surface of the household cooking appliance. The pedestal portion includes a base portion for mounting with the cooktop surface of the household cooking appliance, and an upper portion that interposes the base portion and the burner portion, and interfaces with the burner portion. A perimeter of the base portion has no mathematical correlation to one of a perimeter of the burner portion and a perimeter of the upper portion.
摘要:
A floor-standing home appliance in the nature of a range including an appliance body and a support assembly for supporting the appliance body on a support surface, the support assembly including a support member extending away from the appliance body, the support member having an engagement member with a predetermined shape at a distal end thereof, and a shoe attached to the distal end of the support member, the shoe having a receiving well with a shape complimentary to the predetermined shape of the engagement member to receive the engagement member in the receiving well.
摘要:
A storage apparatus for a measurement probe for use with a coordinate positioning machine. The storage apparatus including a storage unit having at least one receptacle for a measurement probe; and at least one temperature source for controlling the temperature of a measurement probe located in the at least one receptacle.
摘要:
A method and system for determining formation properties based on a fracture treatment that may include collecting data from a fracture treatment for a well. A flow regime of the fracture treatment is determined based on the data. Formation properties may be determined based on the flow regime and the data.
