Abstract: A method and system for vending products from a defined area, such as a micro-warehouse with a door. The method includes fitting each product with a radio frequency identification tag, positioning the plurality of products in a micro-warehouse, sensing opening and closing of the micro-warehouse door, scanning the plurality of products in the micro-warehouse upon sensing closing of the door to determine the number and type of products in the micro-warehouse, generating a message based on the number and type of products in the micro-warehouse, transmitting the message to a remote processor or server, and maintaining an inventory in the remote processor based on the message. The system is designed to be accessed by authorized individuals possessing some type of code or identifying mechanism. The micro-warehouses may be cabinets, refrigerators, secured rooms, or similar storage units or areas.

Abstract: A blender mixes a liquid and a quantity of particulate solids for use in hydrocarbon well operations. The blender is mounted on a vehicle having a suction manifold of rectangular tubing. The long side of the rectangular tubing is vertical, is positioned on one side of the vehicle and provides a large number of inlet connections which, in use, connect to hoses leading to tanks filled with a frac liquid or the like. The discharge manifold may be a mirror image of the suction manifold. The rectangular suction manifold tubing provides greater spacing between the inlet connections and greater volume throughput in use. Also, the rectangular suction manifold tubing is tilted so that the inlets are angled toward the ground.

Abstract: A pair of spooled tubing strings are simultaneously run into a hydrocarbon well carrying a chamber providing a check valve. The chamber is positioned below a hydrocarbon formation so that liquid produced from the formation falls adjacent and passes into the chamber through the check valve. Periodically, gas is delivered through one of the spooled tubing strings to push liquid out of the chamber upwardly through the other of the tubing strings. Gas produced from the formation flows upwardly in an annulus between the spooled tubing strings and a production string in the well. The apparatus can be used to run only one string of tubing into a well and has a number of features, including measuring the load applied to the tubing string and measuring the amount of tubing run into or out of a well.

Abstract: An automatic cementing system and method are disclosed for precisely controlling the density of a slurry during a continuously mixed cement application. The system includes an input water line and a dry cement hopper for supplying water and cement, respectively, to a mixing chamber. The mixing chamber includes two chambers, Chamber A and Chamber B, for thoroughly mixing the water and cement together to form a cement slurry. Chamber B includes a level sensor for measuring the change in slurry level. The input line includes a pump for supplying the water to the mixing chamber, and a flow meter for measuring the rate at which the water is supplied. Similarly, the hopper includes a slide-gate valve for regulating the rate at which the dry cement is supplied to the mixing chamber. A discharge line with a discharge pump and a discharge flow meter receives and discharges cement slurry. A recirculation line is included for density control during initialization.
