A downhole tool has a tool body with a tool body outer diameter. A liner with a liner outer diameter is connected to the tool body. The tool body has a plurality of diverter ports defined in a wall thereof. A closing sleeve is movable in the tool body to close the diverter ports. A closing seat attached to the closing sleeve is a frangible closing seat.

Apparatus and method of reducing surge when running casing

A puddle job can be performed in a wellbore to secure a liner within an open-hole wellbore. A resin in liquid form can be spotted at the bottom of the wellbore. The liner can be lowered into the wellbore to displace the resin up into an annulus between the outside of the liner and the wellbore wall. The resin can be contacted with a solid or liquid initiator to cause the resin to set. The resin can be contacted with the initiator as the liner is being lowered or afterwards. The resin/initiator can be used instead of a cement composition.

Puddle job with delayed setting of resin

A puddle job can be performed in a wellbore to secure a liner within an open-hole wellbore. A resin in liquid form can be spotted at the bottom of the wellbore. The liner can be lowered into the wellbore to displace the resin up into an annulus between the outside of the liner and the wellbore wall. The resin can be contacted with a solid or liquid activator to cause the resin to set. The activator can cause the resin to set via a polymerization reaction such as ROMP, FRP, or step polymerization. The resin can be contacted with the activator as the liner is being lowered or afterwards. The resin/activator can be used instead of a cement composition.

A wellbore fluid inductance monitor is disclosed, which operates at an end of a tubular in a wellbore. The wellbore fluid inductance monitor comprises an inductor in an electrical circuit. A magnetically doped portion of wellbore fluid, which may be a hydraulic fluid or cement slurry, is introduced into the wellbore during a reverse cementing or other cementing operation. The magnetically doped portion of wellbore fluid contains a dopant that alters at least one of a magnetic permeability and conductivity. The wellbore fluid inductance monitor detects the proximity magnetically doped portion of wellbore fluid based on altered electrical characteristics of the inductor. Based on the detection, the wellbore fluid inductance monitor triggers a wellbore operation which is detectable at a cementing controller and the cementing operation can be stopped or otherwise completed based on the determination that the cement slurry has reached the end of the tubular.

A wiper dart having a bi-diameter wiper cup can be used to help track the location of the dart in a pipe string. As the wiper dart is pumped through the pipe string, a first mean pump pressure will exist as the wiper cup travels through drill pipe sections having a larger inner diameter than a tool joint and a second mean pump pressure will exist as the wiper cup travels through the tool joints. The wiper cup can have a geometric shape selected such that a detectable pressure spike can be observed when the wiper cup reaches a transition section located between one end of a pipe section and the tool joint. By counting the number of pressure spikes, an operator can accurately track the location of the wiper dart as it is being pumped through the pipe string.

A wiper dart can be used in an oil and gas operation. The wiper dart can have at least two different outer diameters. A first outer diameter can be less than a second outer diameter and used to wipe the insides of tool joints of a tubing string. The second outer diameter can be used to wipe the insides of pipe sections of the tubing string that have a larger inner diameter than the tool joints. The single, bi-diameter wiper cup can be used in lieu of two or more current, conical-shaped wiper cups to accomplish the same functionality. The wiper cup can include a protruding ring located circumferentially around the wiper cup at the first outer diameter. A plurality of buttons or splines can be spaced apart around the wiper cup at the second outer diameter.

A wiper dart can be used in an oil and gas operation. The wiper dart can have at least two different outer diameters. A first outer diameter can be less than a second outer diameter and used to wipe the insides of tool joints of a tubing string. The second outer diameter can be used to wipe the insides of pipe sections of the tubing string that have a larger inner diameter than the tool joints. The single, bi-diameter wiper cup can be used in lieu of two or more current, conical-shaped wiper cups to accomplish the same functionality. The wiper cup can be generally bell shaped and have a variety of first and second outer diameters.

Provided, in one aspect, is a cementing apparatus. The cementing apparatus, in one embodiment comprising a housing; a fixed member coupled with the housing, the fixed member having at least one fixed member fluid opening therein; and a moving member positioned downhole of the fixed member and movable between a circulating position and a cemented position, the moving member having at least one moving member fluid opening therein, the at least one moving member fluid opening linearly offset from the at least one fixed member fluid opening.

Cementing apparatus for reverse cementing

A valve housing has a first flapper moveable from an open position in the housing in which two-way flow is allowed to a closed position in which only one-way flow is permitted. A first collet sleeve is moveable from a first position to a second position in the valve housing. The first collet sleeve in the first position retains the flapper valve in the open position. The collet sleeve is moveable from a first position to a second position which allows the flapper to move to a closed position.

Differential fill valve with collet sleeve

Systems and methods are provided for determining the end of a reverse cementing operation based on one or more pressure measurements. In some aspects, a cement composition can be delivered to an annulus formed between a casing and a wellbore for reverse cementing the casing. In some cases, a determination that the cement composition has reached a shoe joint at a bottom portion of the casing can be based on a threshold change in a pressure measurement obtained while delivering the cement composition. In some instances, a trigger can be initiated for closing the shoe joint after determining that the cement composition has reached the shoe joint.

Managed pressure reverse cementing and valve closure

Float collar equipment can be bonded to an inside of a casing string via an adhesive. An annulus can be located around an outside of a float collar housing and the inside of the casing string where the adhesive can be injected. The float collar housing does not require external threads or packers to secure the housing to the inside of the casing string. An injection sub can be used to inject the adhesive into the annulus. After curing or drying, the adhesive bonds the housing to the casing string. A seat, seat housing, or float shoe nose can be attached to the float collar housing via an adhesive or threads. The float collar housing can house one or more float assemblies. The float collar equipment can be bonded to the casing string at a wellsite or remote location prior to use in a cementing operation.
