An all-in-one mobile wellsite service unit for providing equipment and services at an oil and gas well related to well abandonment is provided. The mobile unit comprises a water storage tank, at least one cement mixing barrel for mixing a cement slurry, a progressive cavity pump for pumping the cement slurry, and a hydraulic hose for connecting to a hydraulic power source to provide power to the cement mixing barrel and the progressive cavity pump. The mobile unit may also contain downhole tools needed for well abandonment, including a well cleaning tool, a cementing tool, a hydraulic packer, and more.

A containerized concrete batch plant is disclosed, comprising a container configured to contain a concrete batch plant to permit the transportation of the concrete batch plant. The concrete batch plant comprising one or more aggregate storage silos to receive a plurality of concrete elements. The one or more aggregate storage silos pour the concrete elements onto a conveyor based on quantity determination by a computer via a deductive scale. The conveyor transfers the concrete elements to a two-shaft mixer. An auger-fed hopper has an auger that is directly exposed to the contents inside the two-shaft mixer and transfers the contents inside the two-shaft mixer into the auger-fed hopper. A concrete pump has access to the auger-fed hopper and pumps the concrete inside the auger-fed hopper into a concrete output hose with a concrete output opening. A knuckle crane and/or hydraulic arms holds supersacks above the aggregate storage silos and the two-shaft mixer.

A containerized concrete batch plant is disclosed, comprising a container configured to contain a concrete batch plant to permit the transportation of the concrete batch plant. The concrete batch plant comprising a storage silo to receive a plurality of concrete elements from a modular conveyor. An aggregate storage silo receives the plurality of concrete elements for transfer to a scale and the mixing drum. A screw worm drive transfers the plurality of concrete elements from the mixing drum to the concrete pump.

An illustrative method for CO2 sequestration may include the step of sequestering at least a portion of a CO2 gas emitted during operation of the ready-mix concrete production system in (i) a ready-mix concrete produced by the read-mix concrete production system, and/or (ii) calcium carbonate formed by processing water used during operation of the ready-mix concrete production and delivery system.

A quality assurance system for mixing a slurry comprising at least water or other liquid and at least one flowable wet or dry mass, such as cement, sand or other suitable component, has computerized control over the loading of ingredients and has an accurate and broadly variable speed control of the loading of the ingredients. The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber. The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. A damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured. Accurate records of the addition of each ingredient are maintained using the internal computer that controls the invention.

A system for preparing a dry process material includes a sealed container that holds and seals the dry process material therein and prevents airborne dust or particles from the dry process material from escaping the sealed container. Sealed processing equipment receives the dry process material from the sealed container and prevents the airborne dust or particles from escaping the sealed processing equipment. A sealed connection sealingly couples the sealed container to the sealed processing equipment and prevents the airborne dust or particles from escaping while transferring the dry process material. A sealed transfer conduit is sealingly coupled to and extends from the sealed processing equipment.

A quality assurance system for mixing a slurry comprising at least water or other liquid and at least one flowable wet or dry mass, such as cement, sand or other suitable component, has computerized control over the loading of ingredients and has an accurate and broadly variable speed control of the loading of the ingredients. The mixing chamber has scales that provide a signal indicating the current weight of an ingredient in the mixing chamber. As the desired weight of an ingredient is added to the mixing chamber, the computer slows and then stops the inflow of the current ingredient being loaded via broadly variable control of the loading of the ingredients. The broadly variable control of the loading rate of the ingredients allows more accurate control of the final weight of each ingredient added. Further, a damping period allows system vibrations to dissipate, allowing highly accurate weights to be measured. Accurate records of the addition of each ingredient are maintained using the internal computer that controls the invention. The combination of highly accurate control over the input of materials added to the mixing chamber as well as the maintenance of permanent records concerning each batch of cementitious slum made allows the production of precision batches of final products to meet exacting specifications needed in both ordinary projects and highly specialized projects requiring cementitious products. Data recorded during production operations further allow accurate identification of manpower needs of projects and allow owners/operators at job sites to record, control, predict and manage production costs and manpower needs. All recorded data is transmitted to an offsite location for management to use as needed for quality and management control and can be transmitted at any time or hatch interval desired by management.

A waterborne facility on a body of water includes a primary spoolable pipe and a pump. The end of the primary spoolable pipe may be guided from the waterborne facility to a location proximate to a selected site. The pump may be used to discharge a flowable material through the primary spoolable pipe. The waterborne facility may include a ready-mix concrete preparation system. However, the waterborne facility may deliver any flowable material to a selected site, which may be a land surface, underground, on a water surface, or underwater. Illustrative flowable materials include seawater, grout, cement, and sediment/mud.

There is disclosed a system for depositing building materials comprising a motor vehicle, a container comprising a material depositing system and at least one device for removing the container from the motor vehicle. The device can comprise one or more outriggers which are adapted to remove the container from the motor vehicle and which can be used to deposit the container on a job site, There is also disclosed a process as well, which includes at least one of the following steps providing a base slab floor; bull floating the base slab floor, inspecting the base slab floor for debris, utilizing a measuring device to survey height dimensions, applying an adhesive intermediary, inserting plastic pins with respect to survey measured points, mixing a self leveling compound, pumping the mixed compound through a conveying system, and smoothing the mixed compound to create a uniform surface and floor which is cured.
