Patent number: 10323466Abstract: An improved system and method for bracing, transporting, assembling, and disassembly of drilling equipment at oil and gas land-based well sites. The system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with telescoping tension link(s), linking pins, and vertical hydraulic cylinders. These linking pins are set after raising the substructure and secure the telescoping tension link, support arms, and support bracing in place to maintain the integrity of the substructure. Alternatively the system has a substructure with side boxes support bracing that are in a scissor jack (or grand plié) style bracing with screw jacks and a means of stabilization during substructure raising.Type: GrantFiled: August 11, 2015Date of Patent: June 18, 2019Assignee: PIONEER ENERGY SERVICES CORP.Inventors: Christopher Price, D.

Publication number: 20180085564Abstract: A drug-impregnated sleeve for encasing a medical implant is provided. In one embodiment, the sleeve may include a body made of a biologically-compatible material that defines an internal cavity configured to receive the medical implant. In one embodiment, the biologically-compatible material is bioresorbable. The body may include a plurality of apertures, such as perforations or holes, extending from the cavity through the body. The sleeve may further include a first end, a second end, and a drug impregnated into the resorbable sheet. In one possible embodiment, the first end of the sleeve may be open for receiving the medical implant therethrough and the second end may be closed. The implant may be encased in the sleeve and implanted into a patient from which the drug is dispensed in vivo over time to tissue surrounding the implantation site. In one embodiment, the body is made from at least one sheet of a biologically-compatible material.Type: ApplicationFiled: October 6, 2017Publication date: March 29, 2018Inventors: Mark Thomas Fulmer, David A.
