Patent number: 7987904Abstract: 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.Type: GrantFiled: June 17, 2008Date of Patent: August 2, 2011Inventor: James A.

Publication number: 20110114389Abstract: 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.Type: ApplicationFiled: June 30, 2008Publication date: May 19, 2011Inventor: Harold Dean Mathena

Patent number: 7926570Abstract: 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.Type: GrantFiled: March 18, 2010Date of Patent: April 19, 2011Assignee: Hudson Services, Inc.Inventors: Richard Blanchard, Jr., Sandra Remedies, John Rucker, Sr.

Patent number: 7413012Abstract: 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.Type: GrantFiled: June 22, 2006Date of Patent: August 19, 2008Assignee: Geo Estratos, S.A.
