Abstract: A method for making alpha olefins from internal olefins using catalytic distillation techniques and an olefin double bond isomerization catalyst, and separately recovering said alpha olefins.
Abstract: A method for utilizing whole crude oil as a feedstock for the pyrolysis furnace of an olefin production plant wherein the feedstock after preheating is subjected to mild cracking conditions until substantially vaporized, the vapors from mild cracking being subjected to severe cracking in the radiant section of the furnace.
Abstract: A method for processing at least one cyclic organo-oxide using a closed loop scrubber/holding tank system that contains at least one amine, and circulating the amine through the closed loop while admitting the cyclic organo-oxide to the closed loop.
Abstract: A method and apparatus for protecting a polished rod of a pumping unit so that the portion of the polished rod that passes out of the top of a stuffing box of a wellhead on the upstroke of the polished rod is protected from the environment surrounding the wellhead. The method and apparatus also assist with containment of well fluids which may escape from the stuffing box.
Abstract: A sucker rod well pump base that is readily movable and universally adjustable comprising at least two spaced apart footing members which carry, but are not connected to at least two spaced apart transverse support members. A plurality of spaced apart hold down members are carried along the length of the support members in an unconnected manner, but yet are restrained from movement away from the footing members by abutment of the hold down members against the support member. Each hold down member carries at least one tie down member for securing the base to a well pump unit.

Abstract: A method for enhancing the productive capacity of a primary wellbore containing a conduit string such as casing involving removing at least a partial radial section of the casing to provide an aperture therein, setting tubing carrying a guide surface in the vicinity of the aperture and drilling a lateral wellbore at an angle to the primary wellbore using a coiled tubing conveyed drilling assembly.
Abstract: A whipstock and method of using same wherein first and second opposing ends of the whipstock are joined by opposing back and guide surfaces and the second or upper end of the whipstock is composed of at least two surfaces, the first surface being angled so as to direct a well tool impinging thereon toward the guide surface and the second surface being angled so as to provide support for the whipstock when placed in a wellbore at an angle to the long axis of the wellbore.

Abstract: A wellbore anchor tool employing at least one pair of individual slip segments which wrap at least partially around a mandrel passing through the tool, the individual slip segments carrying bearing surfaces and restraint members for holding the slip segments in the tool but at the same time in slidable engagement with the tool.
Abstract: A method and apparatus for setting a whipstock onto a packer in a wellbore wherein the whipstock is laterally and rotatably movable after it is fixed to the packer, whereby the whipstock can move laterally while rotating so that opposite ends of the whipstock can be made to contact opposing inner walls of the wellbore.

Abstract: Wellhead fluid sampling apparatus comprising a closed housing with a side opening for inserting a sample receiving receptacle and a bottom aperture in sealed communication with a removable conduit that is carried by and in fluid communication with the interior of a closed container disposed below the bottom aperture.
Abstract: A combined fluid pumping and storage system which is readily portable and employs a compressed gas operated pump together with a liquid container on a vehicle, the vehicle also carrying at least one compressed gas supply for operating the pump whereby the vehicle is easily transported to a site where liquid is to be picked up for transporting elsewhere and can be operated safely in all conditions including potentially flammable conditions.
Abstract: A fluid spill deflection system and device for use with a wellhead or attachment thereto comprising a flexible sheet-like member having a first aperture for fitting about the wellhead or attachment thereto, a drain, and fastening devices fixed to the member for supporting the member about the wellhead or attachment thereto.
Abstract: Apparatus for containing and collecting leaks from the stuffing box of a fluid producing wellhead comprising collection means carried by the wellhead below the stuffing box and encircling the wellhead and at least two separate upstanding hollow shapes of such cross-sectional configuration that when they are brought into abutment with one another the volume enclosed within abutting shapes encircles the wellhead and extends from the liquid collection means to above the stuffing box, said shapes having apertured top edge means which form an opening that encircles the polished rod that reciprocates through the stuffing box, the shapes being hingedly engaged so they can be pivoted toward and away from one another for ease of access to the enclosed stuffing box as desired.
