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.
The deals, with a potential value exceeding $3.7 billion, are aimed at strengthening Saudi Aramco’s supply chains and expanding its use of industrial artificial intelligence.

This paper presents the results of a performance-improvement effort in extended-reach drilling (ERD) in three campaigns in the Huizhou HZ 25-4 oil field in the South China Sea. -
This paper presents results from full-scale testing of a flexible riser equipped with embedded sensors for distributed-temperature sensing (DTS).

Water condensation and/or hydrate formation at the top of pipelines are serious design/operation considerations in pipelines. This paper reports the results of tests conducted in a new experimental setup constructed for investigating gas-hydrate risks in varied operational scenarios.
-
Vibration-induced fatigue failures of pipework smallbore connections result in elevated safety risks and costly interruptions to normal operations. A common cause is poor design. This article discusses design considerations to avoid these failures.
-
A relatively small concentration of a defoamer can have a significant impact on the dynamics of multiphase flow within a pipe, but the effect is generally temporary.
-
There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade.
-
This paper illustrates a numerical approach to estimate the deposition profile of precipitated wax crystals and its effect on flow-related parameters in pipelines. Options for avoiding these issues are also explored.
-
As with many monitoring and decision support tools, riser management systems originate from the engineering community so may assume a large degree of domain knowledge.
-
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…
