3 results about "Flow assurance" patented technology

The application discloses a centrifugal blade pump with adjustable blade pitch and a flow guarantee control method thereof, and belongs to the technical field of lifting pump systems. The application aims to solve the problem that the traditional centrifugal pump is prone to blockage when lifting solid-liquid mixtures containing large particles. The pump can judge whether blockage occurs according to the flow rate difference by dynamically adjusting the blade pitch and combining with the ultrasonic flowmeter technology to monitor the flow rate in real time. When blockage occurs, the control system adjusts the impeller spacing, reverses the blades and opens the backflow valve to discharge the blockage, ensuring the normal operation of the pump body. The method can avoid pump blockage and improve fluid conveying efficiency. In addition, the system has intelligent control and automatic adjustment functions, can accurately adjust according to the actual fluid working condition, and is especially suitable for conveying large-particle solid-liquid mixtures in the fields of mining, chemical industry, sewage treatment and the like.

The present invention addresses to a real-time flow assurance occurrence monitoring system with the aim of reducing oil production losses caused by occurrences in the flow assurance area, which uses a web tool to integrate results of simulations of multiphase flow and thermodynamic simulators with production data and specific correlations, developed to monitor the formation of deposits or blockages in subsea lines. This tool has the specific objective of monitoring the formation of hydrates, paraffins and emulsions in real time and other occurrences that may cause a production shutdown. Based on this information, it issues an alert of the occurrence in the control rooms of the operational units, supporting decision-making on operational procedures that must be carried out to avoid the loss of oil production. It further records the operations carried out to mitigate occurrences. All data is structured in tables and graphs and can be exported to other systems.

Systems and methods presented herein relate to processing produced oilfield brine by deconstructing it into two useful components: (1) desalinated water and (2) a suspension of solid-state salt (e.g., crystallized salt) slurried in a salt-saturated brine, which may be formulated and injected into hydrocarbon-producing formations above hydraulic fracturing pressure to intentionally create regions of localized high stress within the respective formations. In addition, systems and methods presented herein relate to processing oilfield brine received from hydrocarbon-producing wells by: (1) coupling high-pressure desalination technologies with saltwater disposal (SWD) operations, (2) active management of SWD water composition at the rock face through dual stream (e.g., split-stream) injection, and / or (3) coupled SWD injection, flow assurance, and stimulation to minimize SWD formation damage and injection pressures.
