Pipelines/flowlines/risers
The DeepOcean-lead joint industry project aims to advance commercialization of a new patented technology that heats pipeline systems deployed in deepwater where flow assurance can be a challenge.
BP’s new electric gas compression platform at Shah Deniz, Azerbaijan’s largest natural gas producer, is expected to sustain exports to Europe even as the field enters decline.
Nitzana will enable Israel to double gas exports to Egypt from the giant Leviathan gas field in the Eastern Mediterranean.

A program was devised to test the manufacturability of shrink-fit joints made from high-strength (greater than 100 ksi) mill pipe and forged couplings. -
Gas production in the South China Sea has seen an increasing trend of pipelines operating in high-pressure, high-temperature (HP/HT) conditions. This has led operators to look beyond the conventional stress-based design and move into strain-based design using the lateral-buckling-design approach. This paper presents both construction challenges and operational works p…

As natural gas pipeline systems have grown larger and more complex, the importance of optimization of design and operation of pipelines has increased. This paper examines the optimization issue for the Egyptian gas transmission pipeline network.

Field trials were conducted by BP on the commercial version of wired pipe with a comprehensive suite of logging-while-drilling (LWD) tools, measurement-while-drilling (MWD) functionality, and rotary-steerable- capability on two Wyoming wells in 2007.

Solid-expandable tubular (SET) is widely used to patch casing and has proved to be cost effective.
-
The general industry perception is that, when drillstrings or casing strings exceed conventional helical-buckling criteria, they cannot be operated safely in the hole because the risk of failure or lockup is too high.

Pipelines play a vital supporting role in the energy supply chain as one of the most efficient modes of hydrocarbon transportation. Unconventional resource development and LNG have set the stage for growth in onshore pipelines.

Paradoxical effects can exist when expanding the capacity of natural-gas-transportation networks. This paper derives conditions where it can be expected, how the effect can be masked, and provide analysis to support identification in larger-scale networks.
-
Riser margins were abandoned when fluid columns in risers became too long with increasing water depth accessed when floating drilling units with subsea blowout preventers (BOPs) moved to deep water.
-
A methodology is proposed for design of subsea flowlines and risers coupled with a subsea high-integrity pressure protection system (HIPPS) for fields with high shut-in tubing pressure (SITP).
