Authors Frederic K. Offshore Technology Conference Disciplines 4. Abstract Flow assurance issues associated with deepwater flowlines and pipelines remain central to cost-effective field developments. Wax, asphaltene and hydrate plug formation comprise the key concerns; corrosion, erosion and chemical incompatibility issues also fall within the flow assurance umbrella.

PDF | In the new oil and gas discoveries scenarios, the production of oil and gas occurs far from shore in deep and ultra deep waters.

Flow Assurance Solids in Oil and Gas Production

Power cycles are relatively compact. The reported measurements showed that the RI had a consistent average value of 1. The chemistry is manifested in chemical thermodynamics involving intensive properties independent of size such as temperature, pressure. The book is poduction and should be a must-read for all flow assurance solids professionals.

The fluid mechanics of relevance in flow assurance are asurance in a multitude of text books and other publications, scaling due to mixing of fluids. The abbreviation atm. Introduction Flow assurance, broadly defined, readily available for engineers and scientist in academia and industry. It can be reasoned that linear increase will occur when the deposition driving force is independent of heat transfer at the wall; for example.

Much more than documents.

Flow assurance [1] [2] is a relatively new term in oil and gas industry. It refers to ensuring successful and economical flow of hydrocarbon stream from reservoir to the point of sale. Flow assurance is extremely diverse, encompassing many discrete and specialized subjects and bridging across the full gamut of engineering disciplines. Besides network modeling and transient multiphase simulation, flow assurance involves effectively handling many solid deposits, such as, gas hydrates, [4] asphaltene , wax , scale, and naphthenates. The financial loss from production interruption or asset damage due to flow assurance mishap can be astronomical. What compounds the flow assurance task even further is that these solid deposits can interact with each other, [5] and can cause catastrophic blockage formation in pipelines and result in flow assurance failure. Flow assurance includes thermal investigation of pipelines, making sure the temperature is above the hydrate's formation temperature.


The stopping distance depends on the initial velocity of the particle ui and what is defined as the particle relaxation time. Driven by the high cost of remediation, operators typically specify development schemes focused on ensuring high tolerance to production chemistry and operational upsets. It was concluded that RI could be used to determine the onset of asphaltenes precipitation from crude oils. Pipeline and wellbore cooling lead also to the condensation of water vapour to liquid water.

The classical multiplier method does not include the effect of flow regime? The horizontal line for the bulk saturation temperature in Figure 2. In the absence of solid deposits the plotted line should be constant; in the case of solid deposits the line should increase with time see Section 4. The inten- tion being ;df realistic modelling of solids deposition needs to take into consideration both molecular transport and particle transport.

The desire to understand a subject matter is a powerful driving force. The density is that of the particle and the viscosity that of the fluid. Request an e-inspection copy. For a particular situation, wall shear stress is probably the most important variable in deposition of solids on walls.

In most oil and gas wells, the gravitational pressure drop component controls the flow. The inlet pressure is p1 and the outlet pressure p2. Confident predictions of operating envelopes assuring a clear flow path appear commonplace; efforts to broaden these envelopes may lead to less costly development schemes and higher degrees of operating freedom. The phase behaviour of petroleum assurancce is central in any and all studies of flow assurance solids.
