Patent number: 8651201Abstract: A combined cuttings stream inlet and air stream outlet apparatus, for placement within the inspection hatch of a conventional drill cuttings box, is disclosed. The combined cuttings stream inlet and air stream outlet apparatus has a central cuttings stream inlet conduit, disposed within a larger air stream outlet conduit. The air stream outlet conduit is sized to closely engage the diameter of the inspection hatch when inserted into the hatch opening. The annulus between the two conduits forms a flow area for air to exit the cuttings box. In use, the combined apparatus is easily inserted into the hatch opening of the cuttings box, preferably with a gasket between the apparatus and the hatch opening, and is held in place by the cuttings/air stream. When the cuttings box is full, the apparatus is simply pulled out and inserted into an empty cuttings box.Type: GrantFiled: May 10, 2011Date of Patent: February 18, 2014Assignee: Environmental Drilling Solutions, LLCInventor: Chad Hollier

Patent number: 8641895Abstract: A method and apparatus for recovering oil from oil-containing sorbents, such as drill cuttings obtained from drilling with an oil-based mud. The method includes peptizing the substrate with an acid reagent and direct thermal desorption with combustion effluent gases at high temperature under turbulent mixing conditions. Another method disclosed includes upgrading the oil in the substrate to improve one or more of the properties of the recovered oil relative to the oil in the substrate, such as, lower aromatics content, lower sulfur content, lower functional group content, higher saturates, higher viscosity, higher viscosity index, and any combination thereof. The apparatus provides for efficient recovery of oil from the substrate with a short residence time, high throughput, low residual oil content in the treated solids and/or high percentage of oil recovery. The apparatus may be transported to a remote location for on-site treatment of drill cuttings or other oil-containing solids.Type: GrantFiled: January 14, 2013Date of Patent: February 4, 2014Assignee: Racional Energy & Environment CompanyInventor: Ramon Perez-Cordova

Patent number: 8613329Abstract: A traveling cuttings distributor (TCD) system that is capable of horizontal and vertical positioning for use in vacuuming, auguring or pumping drill cuttings from a drill rig shaker screen trough, drying/minimizing the cuttings and depositing by gravity cuttings while under vacuum into individual cuttings boxes as it moves from one cuttings box to the next or to a bulk system, a cuttings injection system or other cuttings processing system, the system including a vacuum tank having a filter system therein and a large silencer or exhaust system separated by a blower system capable of producing a high vacuum on an opening in the vacuum tank for engaging an opening in a cuttings box or other cuttings processing equipment. The TCD system is capable of being operated without the need for skilled service personnel, while further improving drilling performance, providing reduced environmentally friendly waste material and volumes, recovers expensive drilling mud, thus, reducing the cost of cuttings waste disposal.Type: GrantFiled: May 7, 2009Date of Patent: December 24, 2013Inventor: Jeffrey A. Reddoch, Sr.

Patent number: 8602128Abstract: Systems and methods for analysis of drilling cuttings are described. Complex permittivity is measured of rock cutting samples obtained during drilling operations. The origin of the cuttings is known by flow rate analysis in the drilling system. Various means can be used for rock cutting dielectric measurement. For example, the dielectric measurement can be made by matching the unknown permittivity of the medium to be analyzed to the permittivity of known liquid mixtures by successive saturation and looking for a “zero-contrast” measurement.Type: GrantFiled: April 29, 2011Date of Patent: December 10, 2013Assignee: Schlumberger Technology CorporationInventors: Patrice Ligneul, Valerie Judith Anderson, Tianhua Zhang, Gerald Henry Meeten, Andrew Clarke, Mohammed Badri

Patent number: 8590639Abstract: An articulated pre-skimmer mount for a pre-skimmer associated with a drill bit feed unit comprises a feed mounting arm mounted to the drill bit feed unit. A first end is configured for attachment to the drill feed unit and a second end includes a cylindrical mounting shaft and an axial positioning plate. An intermediate arm has a first end comprising a cylindrical sleeve mounted thereto. The cylindrical sleeve has an inner cylindrical opening configured for sliding engagement with the cylindrical mounting shaft and a mating plate configured for locking, face-to-face engagement with the axial positioning plate. A second end comprises a pre-skimmer mounting assembly configured for attachment to the pre-skimmer, wherein an axial positioning plate and a mating plate are operable to disengage, for rotation of the intermediate arm about an axis of the feed mounting arm for alignment of the pre-skimmer.Type: GrantFiled: February 14, 2011Date of Patent: November 26, 2013Assignee: Caterpillar Global Mining Equipment LLCInventor: Stuart A. Connell
