A method for removing a fluid influx from a subsea wellbore drilled using a pump to return fluid from the wellbore to the surface. The method includes detecting the influx when a rate of the return pump increases. Flow from the wellbore is diverted from the return pump to a choke line when the influx reaches the wellhead. A choke in the choke line is operated so that a substantially constant bottom hold pressure is maintained while drilling fluid continues to be pumped through the drill sgring. Fluid flow from the wellbore is redirected to the return pump inlet when the influx has substantially left the well.

A method for removing a fluid influx from a subsea wellbore drilled using a pump to return fluid from the wellbore to the surface. The method includes detecting the influx when a rate of the return pump increases. Flow from the wellbore is diverted from the return pump to a choke line when the influx reaches the wellhead. A choke in the choke line is operated so that a rate of fluid pumped into the wellbore is substantially equal to a flow rate through the choke line. Fluid flow from the wellbore is redirected to the return pump inlet when the influx has substantially left the well.

The present invention is directed toward a method for preventing, suppressing or mitigating explosions in a confined subterranean chamber, access opening, or entryway of an underground structure such as the manhole of sewers, service boxes, and mining tunnels. The method utilizes a flexible bladder filled with an inert gas or explosion suppressing agent, wherein the bladder is maintained in the chamber in an inflated condition and the volume of the inflated bladder occupies greater than 70% of the volume of the chamber to significantly reduce the amount of space in which an explosive fuel/air mixture may otherwise accumulate. The bladder is heat critical to disintegrate at a predetermined temperature and release a volume of the explosion suppressing agent or inert gas relative to the volume of the chamber which is sufficient to alter the ratio of the fuel/air mixture in the chamber to prevent, suppress or mitigate the explosive reaction. The inflated bladder also serves as a compressible plenum or pressure accumulator to retard ultimate pressure buildup such that the pressures caused by a limited explosion are not transferred to the chamber cover and interconnecting ducts of the subterranean enclosure.

An apparatus and method for supporting pipe main repair tools in an excavation while repairs are being made requires only exposure of the top surface of a buried main and utilizes an anchoring system installed in or above the excavation and an elongate support member that spans the excavation in a generally horizontal position above the pipe main and supports an elongate tubular seal tube against the exposed surface of the pipe main. The elongate support member is secured and supported at opposite ends on the ground surface on opposed sides of the excavation by a pair of parallel laterally spaced shoring members firmly engaged on opposed sides of the excavation, or by a pair of parallel laterally spaced anchor plates firmly engaged on the ground surface on opposed sides of the excavation. The bottom end of the elongate tubular seal tube is engaged on the exterior of the pipe main and an adjustable clamping assembly mounted on the support member supports the seal tube in selective radially extending positions relative to the longitudinal axis of the pipe main. A jack mechanism between the seal tube and the adjustable clamping assembly on the support member forces the seal tube downward to seal against the pipe main. Various tools may be passed through the interior of the seal tube to perform operations on the pipe main.

An apparatus and method for shutting off fluid flow in a pipe main while repairs are being made requires only exposure of the top surface of a buried main and utilizes an anchor system installed in or above the excavation which supports an elongate tubular seal tube against the exposed surface of the main to extend radially therefrom. A jack mechanism compresses the lower end of the seal tube containing a seal member against the exterior surface of the main. A tubular cutting tool installed inside the seal tube is rotated by an air motor to cut a hole in the side wall of the main. A tubular sealant application tool installed inside the seal tube has a nozzle at its bottom end that sprays liquid sealant material onto the interior surface of the main and is then removed. A tubular bladder deployment tool installed inside the seal tube carries a pair of deflated bladders. The bladders are deployed from the deployment tool in opposed direction into the interior of the main along the longitudinal axis of the main and are then inflated to expand and form a seal to shut off fluid flow in the main. After repairs have been made, the bladders are deflated and retracted and the bladder deployment tool is removed. A tubular thread tapping and plugging tool is installed inside the seal tube and rotated to form threads in the cut hole and then removed and then installed again to secure a threaded plug into the hole. After the hole has been plugged, the seal tube is removed.

An extruded slat defined by a series of longitudinal cavities disposed in a side-by-side relationship. Typically, the longitudinal cavities total in odd numbers so that fastening can be achieved through a single cavity. The slat is fabricated from plastic resin, is light in weight, is readily cut and can be arranged into a variety of configurations. Assembly between the ends of abutting slats is usually accomplished by an interconnecting pin(s) between communicating cavities. Each longitudinal cavity is also adapted to receive a rod, a cable, or the like, serving for example, reinforcing, communication and/or communication purposes, or other uses involving concealment and/or security.

A method of rapid earth excavation without damaging buried pipe, cable or other underground objects utilizes drills and augers having soft cutting edges and/or control of the torque and weight of the boring apparatus. In one embodiment, the bit of a drill, or bottom end of an earth auger is equipped with inserts formed of soft polymeric material. Another embodiment of an earth auger apparatus has soft polymeric material on the leading cutting surface of the flight, or the auger flight may be formed of soft polymeric material. The flexibility and low abrasion of the polymeric material prevents damage to the object contacted. Another embodiment has a dual concentric auger with a small earth-auger rotatably mounted inside the shaft of a larger auger and driven independently such that each is capable of providing and maintaining a torque adequate to create a given hole diameter but sufficiently below that which would damage the object expected to be encountered. Another embodiment has an indicator mounted forward of and below the leading cutting surface of the auger to warn the operator of a buried utility or to automatically stop the auger before the cutting surface contacts the buried utility.

A steering system is disclosed for percussion boring tools for boring in the earth at an angle or in a generally horizontal direction. The steering mechanism comprises a slanted-face nose member attached to the anvil of the tool to produce a turning force on the tool and movable tail fins incorporated into the trailing end of the tool which are adapted to be selectively positioned relative to the body of the tool to negate the turning force. The fins are constructed to assume a neutral position relative to the housing of the tool when the tool is allowed to turn and to assume a spin inducing position relative to the housing of the tool to cause it to rotate when the tool is to move in a straight direction. Turning force may also be imparted to the tool by an eccentric hammer which delivers an off-axis impact to the tool anvil. For straight boring, the tail fins are fixed to induce spin of the tool about its longitudinal axis to compensate for the turning effect of the slanted nose member or eccentric hammer. When the fins are in the neutral position, the slanted nose member or the eccentric hammer will deflect the tool in a given direction. The fins also allow the nose piece to be oriented in any given plane for subsequent steering operation.
