New rules requiring Mozambique’s LNG industry to supply 25% of production to the domestic market could stabilize gas deliveries to South Africa’s Secunda industrial center as the Pande and Temane gas fields near depletion.
The Absheron gas field expansion will supply additional natural gas to Azerbaijan’s domestic market and support its export commitments to Turkey, allowing Baku to stay focused on meeting its gas export obligations to Europe.
This work introduces a novel predictive methodology combining historical metocean data with real-time riser analysis for shallow water dynamically positioned rig operations.

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).

This paper discusses the available methodologies for remediation of a pipeline affected by sand and presents examples where the discussed methodologies have been applied.
