  • Patent number: 9689217
    Abstract: An apparatus and method is provided for containing fluid or gas that is released when two adjoining sections of pipe are disconnected. The apparatus can comprise two or more arcuate sections hinged together to form a generally cylindrical or tubular containment chute that can be releasably enclosed around a pipe joint. Latching mechanisms can hold the apparatus around the pipe joint. The apparatus can have one or more sealing members at each end of the containment chute that engage the pipe above and below the pipe joint so that the pipe joint is completely enclosed and sealed off. A spout located on the sidewall of the apparatus allows fluid or gas that is released when the pipe joint is broken to flow from the apparatus through the spout into a hose connected to the spout, whereby the hose can divert the fluid or gas to a receptacle or container.

    Abstract: This invention relates to an ecologically and environmentally friendly mud-gas containment system. Specifically, this invention relates to a mobile device that is capable of receiving waste gas and, in emergency situations, a volume of a mud-gas mixture from a drilling operation. The waste gas is communicated to a removable flare stack through a vent line. The mud-gas is received at a containment vessel. The impact of the mud-gas within the containment vessel separates the mud-gas into mud and waste gas. The mud is collected for recycling and/or environmentally sensitive disposal. The waste gas from the vessel is communicated to the flare stack. Separate removal ports and conduits are used to remove any residual mud or mud-gas from the vent line and/or containment vessel. Excess mud or mud-gas is communicated to an overflow catch tank for removal. The entire assembly is mounted on a mobile skid sized for highway transportation.

The topper is secured to the containment vessel in a liquid tight manner such that the stuffing box is substantially isolated from the environment. As such, any leaks originating from the stuffing box will be contained in the apparatus.

  • Patent number: 7987904
    Abstract: A well cellar system includes a substantially planar base plate, the base defining an aperture sized to receive a conductor pipe. The planar base plate is an integral structural member which, in conjunction with the seal between the base plate and the wall and the riser and the conductor, are sufficiently robust to support the weight of the conductor pipe and its auxiliary equipment. The sealed well cellar is afforded with a laterally extending flange which serves as an anti-buoyancy anchor. A anti-buoyancy port allows the upward floatation pressure to be balanced out by water pressure within the cellar during placement to avoid floatation. A sacrificial anode housing is provided with a removable lid and holes for allowing passage of electrolyte. Although the preferred embodiments of sealed well cellars are metal and plastic, a cementaceous embodiment is also envisioned.

  • Publication number: 20110114389
    Abstract: This invention relates to an ecologically and environmentally friendly mud-gas containment system. Specifically, this invention relates to a mobile device that is capable of receiving waste gas and, in emergency situations, a volume of a mud-gas mixture from a drilling operation. The waste gas is communicated to a removable flare stack through a vent line. The mud-gas is received at a containment vessel. The impact of the mud-gas within the containment vessel separates the mud-gas into mud and waste gas. The mud is collected for recycling and/or environmentally sensitive disposal. The waste gas from the vessel is communicated to the flare stack. Separate removal ports and conduits are used to remove any residual mud or mud-gas from the vent line and/or containment vessel. Excess mud or mud-gas is communicated to an overflow catch tank for removal. The entire assembly is mounted on a mobile skid sized for highway transportation.

  • Patent number: 7926570
    Abstract: A well bore fluid recovery system and method is disclosed for recovering a column of well bore fluid within a stand of casing before cutting the casing. The recovery system relates to a system for preventing fluids from being spilled when casing is being finished for a well bore. After being run the casing must be cut and finished at an appropriate level to install rig equipment such as blow out preventers along with other equipment. However, because of earlier operations, the entire length of casing is typically filled with drilling fluid. Depending on conditions, the length of casing which is to be cut and removed may therefore over a 100-foot (27.4 meter) column of drilling fluid therein. The drilling fluid in this section must be properly drained before the casing is cut and removed.

  • Publication number: 20100236791
    Abstract: A device is described for maintaining a predominately constant pressure on, and flow of drilling fluid in, a drill string (100) where drilling fluid is supplied via a circulation system for drilling fluid. The device comprises a mainly elongated, internally hollow body (10) arranged to surround the drill string where the hollow body (10) comprises at least an upper pressure chamber (40a) and a lower pressure chamber (40b) connected with respective inlet and/or outlet (50a, 50b) for drilling fluid from or to the drilling fluid circulation system, as said pressure chambers (40a, 40b) are able to be closed and separated by an intermediate valve (70) arranged for circulation of drilling fluid into or out of the drill string (100) during coupling up or disconnecting of a new length of drill string (100). A method to maintain the mainly constant pressure of drilling fluid in a drill string is also described.

  • Patent number: 7637692
    Abstract: A well cellar system includes a substantially planar base, the base defining an aperture sized to receive a conductor pipe. The well cellar system also includes at least one substantially inflexible side member attached to the base, the at least one side member and the base defining a cavity. A seal between the at least one side member and the base substantially prevents the flow of fluids between the at least one side member and the base. The attachment between the base and the conductor pipe substantially prevents the flow of fluids between the base and the conductor. The well cellar system of the present invention substantially eliminates contamination of soil and water sources adjacent the well site during its operation.

  • Patent number: 7413012
    Abstract: A method and system for containing escaping hydrocarbon fluid from a well pipe of a production well. Suppression of the hydrocarbon fluid to a level below the breach location using a control fluid allows the breach to be repaired through the installation of a containment sleeve at the location of the breach. After collecting the escaping hydrocarbon fluids with a containment sleeve, the hydrocarbon fluid is routed to a collection reservoir from which it may be easily recovered without causing environmental damage. This process occurs with minimal downtime of the production well with the added environmental benefit of remediation of earth contaminated by the hydrocarbon breach.
