Abstract: Provided in some embodiments are systems and methods for monitoring cement quality of a cased well. Embodiments include conducting a cement-bond logging and a first pulsed neutron (PN) logging to generate a cement-bond log (CBL) and first pulsed neutron log (PNL) for the well, determining a first cement quality index (CQI) for the well based on the CBL and the first PNL, in response to determining that mud effects for the well have dissipated, conducting a second PN logging to generate a second PNL for the well, determining a second CQI for the well based on the CBL and the second PNL, determining a tuned CQI for the well based on the first CQI and the second CQI, conducting a follow-up PN logging to generate a follow-up PNL for the well, and determining a cement quality log for the well based on the tuned CQI and the follow-up PNL.

Abstract: In one possible implementation, a computer-readable tangible medium includes instructions that direct a processor to access one or more wellbore properties and a plurality of well fluid properties. Instructions are also present that direct the processor to access a distance between a proposed location of an inlet to a multiphase production logging tool and an emulsion generation location in a wellbore. Further instructions instruct the processor to predict a drop size distribution of emulsified water in the well fluid at the proposed location of the inlet to the multiphase production logging tool. Additional instructions instruct the processor to compute an estimated error in water holdup detected by the multiphase production logging tool based on the drop size distribution, and recommend deployment of a pulsed neutron logging tool in the wellbore when the estimated error in the water holdup is above a preset threshold.

Abstract: Methods and systems are described for using pulsed neutron ?-ray spectroscopy to measure formation water salinity from within a bore-hole. Through generating a cross-plot of database values of ratios of spectroscopically determined yields of hydrogen (H) and chlorine (Cl) from two detectors, deriving apparent salinities therefrom, formation and borehole water salinities can be determined.

Abstract: A hand-held device for extracting a base of a light bulb from a socket, including a body portion, circular in cross-section, and of a diameter which is easily grasped by the human hand; and constructed of rubber or the like material which does not convey electrical current; a rubber jacket over the body portion having protrusions to allow the user to have a firm, non-slip grip on the device when in use; each end being conically shaped end; the first end being of an increasing conical diameter, so as to allow the end to be inserted into a typically sized light bulb base, and the second end being of a slightly less conical diameter to allow the end to be inserted into smaller bulbs, such as Christmas tree or chandelier sized bulbs. Each of the two conical ends would be hollowed out to a certain extent. Further the surface of each conically shaped end would comprise a plurality of parallel ridges which would provide a firmer grip between the device and the bulb base.

Abstract: A tray apparatus securable to the windshield via suction cups or the like, and for providing a second pair of suction cups which are adjustable in height to be attachable onto the dash board. There is further provided a framework which allows the tray to slide from the frame and rotate to a position below the dashboard at the level of the lap of a driver of a car. When not in use, the tray is returnable to the tray framework so that it may be stored atop the dashboard for further use. There are further included cup holders foldable out from the tray surface for supporting cups therein.

Abstract: A method of assembling a chair back onto a chair bottom by providing a back portion of material having first and second end portions insertable into the chair bottom, boring a hole longitudinally into the ends of the back members, providing a bore transverse to the longitudinal bore on each of the end portions of the chair back, inserting peg member into the transverse bore, the peg member further including a threaded bore which aligns with the longitudinal bore when the member is positioned therein, providing a bolt member insertable into the longitudinal bore from the underside of the chair bottom and threadably engaging the peg member inserted therein, and threadably tightening the bolt member so that as the bolt member is tightened the chair back end portions are fulled in engagement with the chair bottom.

Abstract: A collapsible stool apparatus having a plurality of leg members attached to a wooden seat, and further including a swivel bracket for allowing the legs of the apparatus to be moved from a substantially flat, parallel closed position to an "X" configured open position. There is further included a handle member secured to the lower face of the seat for carrying the stool apparatus when it is in the closed position.

Abstract: A vessel holder for cups or the like, having a generally square or rectangular base portion for positioning on a flat surface such as the dashboard or a seat, a plurality of side members positionable from a storage position substantially horizontal against the upper face of the base, and movable to a substantially vertical position wherein a cup or a bottle may be placed within the space defined by the four upright members. It is further included a wire border which is a generally rectangular portion of wire positionable as a continuous border around the upper portions of the upright sides, in order to define a substantially continuous member in order to hold the side members in an upright position. Further, one of the ends of the upper border is somewhat truncated in order to define an opening in the sidewall so that a handle on the cup may extend therefrom.

Abstract: A system for the assembling of a container such as a planter, which comprises a frame portion which can be assembled through the inter-connection of individual components into a desired shape such as a circle, triangle, or rectangle; a wall portion attachable to the outside of the frame, after the frame has been assembled, with the wall portion further including a plurality of wooden slats adhered to the back face of a flexible material, with the slats positioned adjacent one another in parallel relation, so that the second face of the material can be adhered to the outside of the frame, and after the material has encircled the frame, the slats on the outer face of the material serves as a decorative exterior wall of the container such as a planter which would encircle the entire container such as a planter.

Abstract: An apparatus adaptable to a trash bin, the bin being of the type having four side walls, and a swinging door panel on the upper portion of one of the side walls, for allowing the panel to be manually opened and a tray to be slid within the opening and food or trash allowed to be dumped from the tray into a trash can contained within the bin. The apparatus would comprise a foot pedal hingedly secured to the interior wall of the bin, and an opening above the foot pedal so that one may have access to the foot pedal with one's foot, a line running from the front face of the foot pedal upward and interconnecting the interior face of the door panel; and a pulley secured to the side wall of the bin, so that the line runs over the pulley, in such a fashion when one places force downward on the foot pedal, the line is retracted so that the door panel is swung into the opening within the container, thus giving access to the container through the opening formed by the opened panel.
