Abstract: A technical merit index-based web model for implementing a technical merit index tool facilitates product selection. A technical user input section is populated via a global network with defined selection factors and desired values for each of the selection factors for a product to be selected. A product supplier input section is populated via the global network with product specifications relating to the defined selection factors. A technical merit index is determined for each candidate product based on a summation of normalized product specifications for each of the defined selection factors relative to the desired values. The web model and method facilitate product selection using objective criteria that is weighted based on the importance of the respective selection factors.

Abstract: An adaptor for a top tensioned riser that allows the riser to be tied in with wellheads beyond the normal range of the top tensioned riser. An adaptor spool attaches between the top tensioned riser and the subsea wellhead. An adaptor spool hanger may land in the adaptor spool. The adaptor spool is provided with a side penetration to which a flow line may be connected. The flow line is provided with a connector that connects to a production line from a remote location. This allows the fluid production to flow from the remote location through the existing top tensioned riser to the host facility. The tieback connector/stress joint may also be provided with a flow line prepared to accept remote field tiebacks, which are also piggable.

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.

Abstract: An automated density and chemical controller automatically controls the density and chemical proportions of a slurry that is injected into a well during a well fracturing operation. The automated density controller receives from the operator the parameters of the fracturing operation and automatically controls the addition of a proppant to water to produce a slurry with a desired density. The automated density controller measures the incoming flow of water into a blender tub and regulates the delivery of proppant in the blender tub to produce a slurry of the desired density. The performance characteristics of the mechanism used to deliver the proppant are programmed into the controller to enable the controller to regulate the quantity of proppant delivered by controlling the operational speed of the delivery mechanism. The automated chemical controller regulates the addition of chemicals based on the incoming flow rate.

Abstract: A heat exchanger tube bundle extractor having an improved sled and motive means operable to move the tube bundle into or out of its shell. A fixed screw shaft is provided on the chassis, and a rotatable drive nut on the sled. The drive nut is threadedly retained on the screw shaft. The drive nut is held against axial movement with respect to the sled by a gear box disposed on the sled. The gear box output includes a rotating shaft to which the drive nut is connected, which provides the drive nut with the appropriate speed and power to effectively pull the tube bundle from, or push it back into, the shell. A balance nut disposed on the opposite end of the drive shaft from the drive nut, and threadedly engaged with the screw shaft, reacts against side forces on the sled and screw shaft to assist in keeping the drive nut and screw shaft properly aligned.

Abstract: An automated density and chemical controller automatically controls the density and chemical proportions of a slurry that is injected into a well during a well fracturing operation to produce a slurry with a desired density. The automated controller automatically controls the addition of a proppant to water based on the parameters of the fracturing operation, the incoming flow of water into a blender tub, the incoming flow rate of chemicals, and the performance characteristics of the mechanism used to deliver the proppant. The automated density controller also measures the flow of the slurry discharged from the blender tub and calculates the actual density of the slurry. After comparing the calculated actual density with the desired density, the automated density controller calculates a correction factor and recalibrates the performance characteristics of the proppant delivery mechanism. The automated density controller also includes a densiometer for measuring the actual density of the slurry.
