Abstract:
A method of formulating a wellbore fluid may include adding a ground weight material comprising barite and quartz, having a d50 between about 4 and 8 microns and a d90 between about 15-25 microns, to a base fluid; and mixing the base fluid and ground weight material to form a mixed wellbore fluid.
Abstract:
A wellbore fluid treatment may include a compound formed from reaction between cyclic anyhydride pendant groups on a polymer backbone with at least one amino acid, neutralized with a nitrogen containing compound. Methods may include injecting such a compound into a hydrogen production stream. Other methods may include reacting polybutadiene grafted maleic anhydride with at least one amino acid to produce an intermediate; and reacting the intermediate with an amide, amine, or imidazoline having at least a C4-C24 group to produce a compound.
Abstract:
A composition may include a branched polymer to encapsulate a guest molecule to be released under oilfield conditions. The guest molecule may include a production chemical, such as a scale or corrosion inhibitor. The branched polymer may be substituted with fatty acids. The branched polymer may also function as both an ecapsulator as well as a production chemical in certain applications.
Abstract:
An apparatus and a method filters particles using a screen assembly with an inner section, an outer section and a screen material. The inner section and the outer section form an opening. The screen material is stretched across the opening and is supported by the inner section. The inner section is flexible relative to the outer section. When particles are introduced to the screen material, the inner section flexes to reduce strain on the screen material.
Abstract:
Methods may include circulating a breaker fluid into a wellbore, the breaker fluid containing: a base fluid, a peroxide source, and a catalyst. In another aspect, methods may include drilling a wellbore with a drilling fluid containing a catalyst, and circulating a breaker fluid into a wellbore, the breaker fluid containing a base fluid, and a peroxide source. In yet another aspect, methods may include treating a contaminated fluid with a treatment fluid containing a base fluid, a peroxide source, and a catalyst.
Abstract:
A waste processing system includes a lower tank portion coupled to a first support frame with a guiding member. The waste processing system further includes an upper tank portion coupled to a second support frame, the second support frame including a leg defining a hole for receiving the guiding member to align the first support frame with the second support frame.
Abstract:
A drilling fluid control system (100) has subsystem modules (102A-102H), an output (104) and an input (106) connected with interconnecting conduit (110). Each subsystem module (102A-102H) has a function. The subsystem modules (102A-102H) may be an active mud pit module (102A), a mud mixing module (102B), a chemical storage module (102C), a rig pump module (102D), a back pressure control module (102E), a primary shaker module (102F), a secondary shaker module (102G) and/or a shaker pit module (102H). The subsystem modules (102A-102H) with the same function may be interchanged without changing the input (102), the output (102) and the interconnecting conduit (110) of the drilling fluid control system (100). Additionally, the sub-system modules (102A-102H) are configured to fit within intermodal shipping containers.
Abstract:
A dual pass shaker system and method has a first line of shakers and a second line of shakers. The first line may be parallel shakers, and the second line may be series shakers or a combination of each. Arranging the shakers above each other conserves space. The shaker system maximizes screen area exposure from the dual pass system over and/or through the stacked design of the shakers. The system allows customizing the flow of the slurry through the shakers via valves and a distribution manifold to maximize the number of screens over which the slurry flows. The slurry flows through any configuration of shakers desired.
Abstract:
Wellbore fluid compositions containing a base fluid; at least one synthetic fiber; and a particulate solid are provided. In another aspect, methods of reducing loss of wellbore fluid into and strengthening of a formation are provided, including: introducing into the wellbore a fluid composition comprising one or more synthetic fibers and one or more particulate solids.
Abstract:
A method for measuring particle size distribution in a fluid material, involving inserting a laser beam instrument directly in the fluid flow line, wherein the laser beam instrument focuses a laser beam on a window directly coupled with the fluid flow line, wherein the fluid flow line comprises a fluid having a plurality of particles of different sizes, measuring a diameter of at least one particle in the fluid flow line by reflectance of the at least one particle as the at least one particle passes through the focused laser beam, and determining a duration of reflection of the at least one particle, and obtaining a count of particles in each of a pre-set range group of particle sizes, wherein the count of particles is used to determine particle size distribution in the fluid flow line.
