Hydrate-Induced Vibration in an Offshore Pipeline
A computational fluid dynamics model is proposed to analyze the effect of hydrate flow in pipelines using multiphase-flow-modeling techniques. The results will identify the cause of pipeline failure, regions of maximum stress in the pipeline, and plastic deformation of the pipeline.
Managing the Risk of Hydrates Offers Alternative to Avoidance Strategy
The 9th International Conference on Gas Hydrates featured discussions on key advancements in flow assurance, including the concept of risk management and anti-agglomerates being applicable strategies in transient operations.
Understanding Risk in Flow Assurance Management
A BP flow assurance manager explains a methodology for determining and mitigating flow assurance risks.
Gas Hydrates: A Matter of Risk?
A BP flow assurance engineer discusses the shift in hydrate management strategy from complete avoidance to risk mitigation for an offshore dry tree facility.
Thermal Regime Effect on Gas-Transport Lines in the Persian Gulf
Sea lines transporting gas in the Persian Gulf exhibit different thermal regimes in different regions. This study summarizes hydrate-inhibition practices for these sea lines, and indicates a possibility of using them as indirect thermometers to provide important physical oceanographic data.
Three Key Principles To Solving Operational Flow Issues
When the underlying cause of flow-related issues on offshore projects is unknown, an expert said an investigation of fluid flow behavior based on an understanding of the first principles of flow assurance is necessary.
An Evaluation of Risk of Hydrate Formation at the Top of a Pipeline
Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.
Flow Assurance -Hydrates and Paraffin Management
As environments become more challenging, the importance and complexity of flow assurance has evolved. To effectively manage flow assurance, oil and gas operators must take a holistic approach, particularly when working in deepwater offshore environments.
Hydrate Risk Assessment and Restart-Procedure Optimization of an Offshore Well Using a Transient Hydrate Prediction Model
This paper describes a gas-hydrate model for oil-dominated systems, which can be used for the design and optimization of facilities focusing on the prevention, management, and remediation of hydrates in flowlines.
Gas Hydrate Control Using Monoethylene Glycol in the Gulf of Mexico
One of the more challenging flow assurance problems in deepwater subsea gas pipelines and equipment is the formation of natural gas hydrates. Gas hydrates form under conditions of low temperatures and high pressures, such as those found in deep water.
