Enhanced-Gel-Strength Concept Optimizes Chemical Use in Pipeline for Waxy Crude
Banyu Urip crude contains 26% wax, which can lead to flow-assurance challenges in a crude pipeline exposed to lower temperatures. Injection of pour-point-depressant (PPD) chemicals has been considered an effective method to ensure flow of moderate waxy crude.
Novel Polymer Modifications Lead to Next-Generation Pour-Point Depressants
Current logistics and pipeline-infrastructure limitations make transportation and production of waxy crude oil challenging, necessitating a step change in the chemistry required to mitigate crude-oil-composition issues.
Reassessing Operational Strategies for Wax Management Reduces Expenses
This paper presents a case study that is an example of how reassessing a flow-assurance risk-management strategy for operating assets can identify opportunities for optimization.
Is the Permian Barreling Toward a Breaking Point?
Permian oil output is growing fast, pipeline capacity is full with little relief in sight, truck drivers are in short supply, and the value of basin-produced crude is sinking. Is a drop off in activity—including drilling and production—becoming inevitable?
Developing an Influx-Management Envelope for a Deepwater MPD Operation
The influx-management-envelope (IME) concept is an advanced, innovative way to assess influx conditions in managed-pressure-drilling (MPD) operations, offering an improved tool for the decision-making process.
Offshore Production and Flow Assurance
Mitigation of flow-assurance problems continues to drive new production-technology applications and approaches. The three papers highlighted here focus on minimizing costs while providing safe, effective, and reliable operations.
Wax-Deposition Experiments Decouple Hydrodynamic Parameters To Aid Scaleup
In this study, the effects of the hydrodynamic parameters are decoupled with specially designed flow-loop experiments. The results enhance understanding of the deposition behavior at various hydrodynamic conditions and aid in scaling up from laboratory to field conditions.
Low-Adhesion Coatings Provide Novel Gas-Hydrate-Mitigation Strategy
In this study, two coatings were produced and evaluated to determine their effect on hydrate adhesion onto carbon-steel surfaces.
Transient Simulation for Hydrate Mitigation Aims for Optimal Production in Kuwait Fields
This paper presents the traditional methods of hydrate mitigation used in the NKJ fields and the way in which a transient model was initially built and continuously improved.
Monitoring and Mitigating Asphaltene Issues in a Deepwater Production System
This paper presents an integrated approach to evaluate the key elements of asphaltene risk for deepwater projects, the strategy to manage the issues during production implementation, and aspects to be considered in the mitigation of asphaltene in the field-development plan.
Laboratory Testing and Prediction of Asphaltene Deposition in Production Wells
This paper presents a methodology that begins by determining the ADE in the laboratory. Moreover, asphaltene-deposition rates for the tubing conditions can be measured using high-pressure/high-temperature coaxial-cylinder technology.
Cointerpretation of Distributed Acoustic and Temperature Sensing for Inflow Profiling
With the availability of more-complex smart-well instrumentation, immediate evaluation of the well response is possible as changes in the reservoir or well occur.
Efficient Optimization Strategies for Developing Intelligent-Well Business Cases
The complete paper evaluates optimization techniques to develop, or support, business cases for intelligent or smart wells.
Squeeze Treatments Combat Scale Deposition
At the 2017 SPE Oilfield Chemistry Conference, an assistant professor from Heriot-Watt University discusses the optimization of squeeze treatments delivered by diving support vessels.
Offshore Production and Flow Assurance
Subsea tieback of a new field to an existing offshore production facility is one option to minimize development costs.
Direct Electrical Heating of a Flexible Pipe
This paper describes a new direct electrical heating method in flexible-pipe systems. The method effectively expands the operational envelope of flexible unbonded pipes with greater control of hydrate plugs and wax precipitation by distributed heating along the entire pipe length,
Thermoplastic-Composite-Pipe Flowline Helps Reduce Project and Life-Cycle Costs
Thermoplastic composite pipe (TCP) is a spoolable, fully bonded pipe with glass or carbon-fiber reinforcements. While most often used in deep water, the combination of a solid wall, spoolability, and corrosion resistance makes TCP attractive for production-flowlines in shallow water also.
Flow-Assurance Methods Enabled by Medium-Voltage Heating Technology
Medium-voltage electric heating systems offer reduced installation cost and increasing efficiency for multimegawatt oil and gas heating applications compared with low-voltage systems. For offshore applications, the systems offer the added benefit of both space and weight reductions.
