The Price of Permian Gas Pipeline Limits
Pipeline bottlenecks have created a wide gap in the price of gas at a key pipeline hub in the Permian compared to the US benchmark level.
Study of Expandable-Tubular Collapse Leads To Risk-Based Strength Development
The objective of this study is to investigate comprehensively the effects of the expansion process on the pipe mechanical properties and collapse performance and to develop a reliable risk-based collapse-strength design for the expandables.
Risk-Based Statistical Approach To Predict Casing Leaks
A probabilistic approach was introduced to improve interpretation of data from electromagnetic corrosion logs. This paper presents a statistical risk-based approach to predicting casing leaks using electromagnetic corrosion logs.
Reliability-Based Casing Design Unlocks Reserves in a High-Pressure Gas Field
This paper presents work performed to characterize the probability of collapse as a function of reservoir-abandonment pressure using reliability-based design (RBD).
Risk-based design is very important, especially for complex systems, because a deterministic approach may not provide a strong underpinning to the reliability estimation of the downhole tools. We have to reduce the probability of failure.
Marriage of Ideas Could Allow More Deepwater Gas to Shore
When two engineers lost their jobs during the industry downturn, they used the misfortune as an opportunity to develop an innovative concept that aims to make it a lot easier to move subsea gas long distances.
DeepStar Accomplishments in Continued-Service Realm
Offshore operators must grapple with ways to keep aging floating facilities on station beyond their original design life.
Robotics Hits Tipping Point for Oil Industry Breakthroughs
The CEO of Houston Mechatronics told an Aramco Innovation Day audience that robotics is at the same point that the Internet and online communication were at in the mid-1990s and will soon become “the iconic technology of this century.”
Improving Casing Integrity by Induction Brazing of Casing Connections
Brazing technology allows metallurgical joining of dissimilar materials by use of a filler material.
Collapse Analysis of Perforated Pipes Under External Pressure
This work is a study of collapse pressure of perforated pipes to evaluate the effect of lateral perforations on the radial resistance of pipes under external pressure.
We have seen in recent years many technological advancements in tubular-manufacturing technology. Tubulars also have become part of the data-transmission network and slowly will converge with the data-handling and data-transmission systems.
First Expandable Liner-Hanger Installation in UAE in an HP/HT Well
This paper discusses the planning and deployment of an expandable-liner-hanger (ELH) system in an offshore high-pressure/high-temperature (HP/HT) well for the first time in the United Arab Emirates (UAE).
Mitigating Gas in Riser Rapid Unloading for Deepwater Dual-Gradient Well Control
A study using a dynamic multiphase-flow software simulated a rapid-unloading event and determined the gas fraction in the riser annulus and the effect on riser fluid levels.
Qualification of Composite Pipe
This paper describes the qualification process for a thermoplastic composite pipe manufactured for use in high-performance riser, jumper-spool, and intervention-line applications.
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.
Riser-System Design in Water Depths Greater Than 3000 m
This paper evaluates the feasibility of a number of production- and export-riser configurations for ultradeepwater applications.
A New Method To Detect Blockage in Gas Pipelines
This paper presents a multirate-test method to detect locations and sizes of blockages in gas pipelines.
Miniaturized Coiled-Tubing System Reduces Costs During Pipeline Decommissioning
This paper presents the challenges and obstacles faced in the use of a new technology for the plugging and deoiling of sections of unpiggable flowlines before decommissioning.
Increasing Production by Applying Active Slug-Suppression Technology
Active slug-control methods have been developed in recent years. One such system is a relatively inexpensive solution developed by Shell that has proved to be very effective in stabilizing slugging in flowlines and risers.
More Exact Measures Raise Tough Questions: Regulators and Drillers Adjust to Precise Fluid Flow Measures
More precise measurement can create a dilemma. One example is the precise fluid flow measurements used to control managed pressure drilling (MPD) systems.
Offshore Operators Shed Costs, But Can They Keep Them Off?
Offshore drillers have been battered by the plunge in oil prices with falling day rates and a growing number of older rigs headed for demolition.
The roles of wellbore tubulars in delivering continued well integrity are diverse, critical, and congruent throughout the life of the well.
Detection of Kicks With Networked Drillstring and Along-String Pressure Evaluation
This paper describes efficient detection of well-control events, in both underbalanced and overbalanced conditions.
Development of Drillpipe-Riser-Intervention Systems Offshore West Africa
This paper details the technical and economic challenges in west Africa that have led to the design of drillpipe-riser-intervention-system (DPRIS) solutions.
The New Pathways of Multiphase Flow Modeling
In the realm of enabling technologies, multiphase flow modeling has proven to be one of the most important to the oil and gas industry. Without it, nearly all subsea wells would be too costly or dangerous to develop.
Olga: A Subsea Evolution
Created by the Institute for Energy Technology in Norway in 1979, Olga was the oil and gas industry’s first transient multiphase flow model. A source of national pride, the program has been declared one of the country’s most important innovations in recent decades.
Composite Flowlines, Risers, and Pipework in Offshore Applications
