Abstract: A system for monitoring a dual cylinder concrete pumping apparatus and a transition valve operated by an actuator. The system including position sensors to detect the position of pistons in the dual cylinders and the actuator. Additional sensors can monitor various aspects of the concrete pumping apparatus. A processor receives information from the sensors and transmits data to a monitor. When sensor data is outside of predetermined parameters, the processor sends an alert notice and a performance snapshot of the system to the monitor.

Abstract: Methods for diverting treatment fluids to less permeable zones of subterranean formations using a water swellable agent that can degrade at high temperatures are provided. In one embodiment, the method may comprise introducing a water swellable agent into or adjacent to a permeable zone of a subterranean formation; introducing an aqueous solution into the subterranean formation to contact the water swellable agent; allowing the water swellable agent to swell when contacted by the aqueous solution; introducing a treatment fluid into the subterranean formation, wherein the water swellable agent diverts the treatment fluid away from the permeable zone; and allowing the water swellable agent to thermally degrade.

Abstract: One example of well treatment design based on three-dimensional wellbore shape can be implemented as a computer-implemented method. Wellbore data including acoustic logging data that defines an internal shape of a wall of the wellbore at multiple locations around the perimeter of the wellbore can be received. A volume of an open hole portion of the wellbore that includes the multiple locations can be determined using the wellbore data. Using the volume of the open hole portion of the wellbore, a volume of a fluid loss treatment to treat the portion of the wellbore for well fluid loss can be determined.

Abstract: A large scale processing method for separating banana pulp from its peel is shown. In this method bananas are separated into two parts (generally in a transverse direction), each part having a tip end and a cut end. A compression force is applied to those banana parts such that the force increases from the tip end to the cut end. A device which implements that process, including a cutting device, a means for feeding bananas into the cutting device, and two processing conveyor devices (to apply the compression force to the banana parts), is also shown.

Abstract: Crosslinkable polymer compositions are provided that may be useful for, among other things, reducing, stopping, or diverting the flow of fluids in subterranean formations. The crosslinkable polymer compositions may comprise an aqueous fluid, a chitosan-reacting polymer, chitosan, and a gelation-retarding additive comprising an acid derivative. Various methods of use are also provided.

Abstract: A device which separates banana pulp from its peel, suitable for large-scale processing, is disclosed. The device consists of upper and lower conveyor belts, a roller installed above the upper belt, and a pressure generating element (e.g., a roller or a plate) installed below the lower belt. The belts are installed so as to converge in the direction of their movement. The axes of the roller(s) is oriented between the longitudinal direction of the lower belt and its transverse direction.

Abstract: This application discloses a method for separating banana clusters into individual fruits. In this method, the banana cluster is hung on a carrier (such as a cable) in such a way that the hanging point is the place where the banana fruit stalks converge (at the crown). The cluster and/or the cutter are moved toward each other and the cutter is positioned such that the cutter cuts the fruit stalks at a point lower than the cluster hanging point.

Abstract: The invention provides for a composition for treating a subterranean formation, the composition comprising: a) a crosslinkable water-soluble polymer comprising at least one acylated amine unit; and b) a crosslinkable water-soluble polymer comprising a functional group selected from the group consisting of carboxylic acid and carboxylic acid derivative. The invention also provides for a method of treating a subterranean formation penetrated by a wellbore, the method comprising the steps of forming the treatment fluid and introducing the treatment fluid through the wellbore and into contact with the formation.
