The Jet and Resolved Features of the Central Supermassive Black Hole of M87 Observed with EHT in 2017—Comparison with the GMVA 86 GHz Results

Published: February 2024

Abstract
M87 is the best target for studying black hole accretion and jet formation. Reanalysis of the Event Horizon Telescope (EHT) public data at 230 GHz shows a core–knots structure at the center and jet features. We here compare this with the new results of GMVA at 86 GHz showing a spatially resolved central core. There are similarities and differences between the two. At 86 GHz, “two bright regions” are seen on the ring in the core. The “core–knot–west knot” triple structure in the 230 GHz image shows apparent appearance of two peaks similar to the “two bright regions” when convolved with the GMVA beam. This similarity suggests that both frequencies reveal the same objects in the core area. Protrusions are observed on both the south and north sides of the core at both frequencies, becoming prominent and winglike at 230 GHz. The 86 GHz image shows a triple ridge jet structure, while the 230 GHz image shows only a bright central ridge with two roots. Both frequencies show a shade between the core and the central ridge. To detect the faint features from the EHT2017 data, we found that the use of all baseline data is essential. Using all baseline data, including the ultrashort data, revealed the jet and faint structures. Without the ultrashort baselines, these structures were not detectable. The lack of detection of any faint structures other than the ring in the M87 data by the EHTC is presumably due to the exclusion of ultrashort baselines from their analysis.
(Re)devenir Hui : l’ethnicisation d’une municipalité autonome à Baiqi (Fujian)
Authors: Bugnon Pascale 
Published: February 2024

Cet article traite de la fluidité de la catégorisation ethnique aux abords de la ville-préfecture de Quanzhou (province du Fujian), où le lignage Han des Guo a été récemment reconnu comme Hui. Cette transformation catégorielle a impliqué la création d’une municipalité autonome Hui en 1990 et une nouvelle visibilité de la « musulmanité » de ce groupe. Si le rôle politique de catégorisation ethnique se doit d’être souligné, l’identité Hui ne peut être réduite à une invention de l’État. En observant les pratiques cultuelles de ce lignage et les interactions interethniques avec les Hui du nord-ouest, il est possible d’appréhender la plasticité catégorielle de ce groupe ethnique, faite de réappropriation et de controverses.
Highlights and Unique Lessons Learnt From Multiple Interventions on a Deepwater Asset in Malaysia
Authors: Vevakanandan Valsan , Ting Angelina , Zaidil Hanani , Lin Lai Chin 
Published: February 2024

Abstract
A field is a faulted anticline structure lying in a deepwater turbidite environmental setting, which consists of four main sand bodies that were targeted over two phases of development. The field is accessed via a Tension Leg Platform (TLP) structure, about 100KM from the shores of Sabah, with water depths of around 1600ft. Most of the historical production in the field comes from two reservoirs, which have had varying degrees of performance across the field with challenges ranging from secondary gas caps, to increasing water cuts and formation impairment. Part of the field management strategy has been to either introduce water injection to maintain pressure, or GOR limit relaxations when additional pressure support is not possible. Difficulties that add to the field is the non-uniform depletion of the reservoir due to either structural compartmentalization (which is highly prevalent in this field) or sedimentary complexities due to thin bed production, uncertain fluid movements and skin introduced via fines migration.
Since 2018, multiple logging campaigns have been conducted on both reservoirs to characterize and diagnose the nature of inflows with various solutions proposed depending on the outcomes. To date, the field has employed multiple gas shut-offs, water shut-offs and acid stimulation jobs that have led to highly profitable successes along with failures that have informed future and ongoing work in the field.
This paper will attempt to summarize the various interventions made on the field and the subsequent solutions proposed and implemented, which has led to significant incremental gains from the brownfield where successful and lessons learnt where solutions proposed were less optimal. The multiple campaigns conducted on this field has also led to great efficiencies in the interfaces between the various groups, from vendors, to wells, asset and subsurface with results and mitigations regularly proposed and supported by the various joint venture partners and regulators in the field. The uniqueness of the challenges faced in this Deepwater field is the ability to intervene ‘relatively’ cheaply to diagnose the problems given the dry-tree nature of the TLP, as opposed to subsea type wells requiring huge operational costs that are commonly found in other similar Deepwater type developments. This provides the unique opportunity to trial multiple state of the art type intervention techniques where even the smallest possibility of success potentially pays off for multiple campaigns. The technical learnings should therefore be highly applicable to many assets, and the ways of working and interfacing that will be demonstrated should be replicable in other places.
Recent Active Heating Breakthrough and New Opportunities for Deepwater Tie-Back
Authors: Suhaimi Radzlan Ahmad , Michel Xavier , Roux Arnaud , Minier Yves , Reboul Pierre 
Published: February 2024

Abstract
Given the sustained oil and gas demand, there is a constant trend among oil and gas companies to develop new prospects and maintain the current production level. This trend is paralleled by an increased focus on innovative technological solutions aimed at accessing more demanding, remote, and deepwater hydrocarbon reservoirs, primarily driven by the diminishing output from shallow water brownfields. These reservoirs can present fluid properties challenges, including high wax and hydrate content. This gives rise to flow assurance challenges, which, in turn, have repercussions on production costs, potentially rendering the development of such fields economically unviable through conventional methods.
Following years of technology development, Electrically Heat-Traced Flowline (EHTF®) is the advanced heating technology equipped to tackle these flow assurance challenges. This technology reached a key milestone in 2022 - demonstrated performance in service (TRL 6). The test protocol exhibited live production and shutdown situation, during which active heating was successfully switched on. The successful completion of the in-service performance test of the first commercial EHTF®, combined with subsequent delivery and installation of similar product, has changed the profile of active heating solutions for subsea tie-back.
The first part of the paper shall delve into the fundamental scientific principles behind EHTF®. Subsequently, the paper will explore on the recent successes in the installation of the EHTF®, from the initial product development, subsequent design and qualification stages, through fabrication, installation, and eventually commissioning of the subsea tie-back.
The next section will examine EHTF®’s track records on various projects, how performant is the technology during operations, and how fit-for-purpose configuration is recommended when developing active heating system for specific field developments. This part will discuss the EHTF® product portfolio, the corresponding envelope of application to cater for multiple fluid challenges and tie-back distances as well as its Technology Readiness Level (TRL).
The paper will then present a description how the EHTF® can be tailored to meet specific field application needs, expanding its potential usage. To provide a wider perspective on the EHTF®, we will present a qualitative comparison with the alternative active heating solution, the Direct Electrical Heating (DEH) solution. In the last section a typical EHTF® tie-back will be presented, in the context of deepwater field in the South China Sea prior to concluding the paper.
Challenges in Integrity Assessment of TMCP Pipeline Girth Welds in Severe Sour Service
Authors: Prakash V. , Gomez K. B. , Fisol A. C. 
Published: February 2024

Abstract
In recent years, the number of developed gas and oil fields with an increased content of hydrogen sulphide is increasing. Metallic materials such as carbon steel and weldments can become brittle and crack in sour environments due to a combination of chemical, physical and electrochemical factors. Following the industry experience with premature failure of Thermo-mechanically Controlled Process (TMCP) steel pipes handling sour gas, stringent requirements have been established for integrity assessment of linepipe longitudinal seam and girth welds. Commonly used reference is DNV-RP-F108 with certain project specifications from operators. This paper identifies the gaps and potential conservatisms from multi-disciplinary inputs used for integrity assessment using fracture mechanics, commonly referred as Engineering Criticality Assessment (ECA). This work also briefly elucidates the resulting fabrication challenges associated with a stringent girth weld acceptance criterion.
Integrity assessments of flaws in pipeline system girth welds is typically performed based on a fitness for purpose approach using fracture mechanics principles. Commonly used standards are DNV-RP-F108 and BS7910 for pipelines and risers. Parametric fatigue and fracture assessments have been performed using Crackwise software. These results have further been compared with crack driving force from the Finite Element Analysis software, ABAQUS. Solid 3D FE modelling and assessment of crack driving force for fracture has been performed by evaluating the J-integral.
The influence of key parameters such as fatigue and fracture characterization of parent pipe and girth weld, associated loading, weld geometry, and Non-Destructive Evaluation (NDE) inspection accuracy has been discussed. Potential impact to welding acceptance criteria, associated inspection challenges, and risks to overall project schedule has been discussed. Gaps to DNV-RP-F108 have also been identified and potential solutions recommended.
This paper provides a holistic view based on recent experiences in sour service application that can be used as basis for revising DNV-RP-F108 for integrity assessment of girth welds. It can be used as a basis for standardization of sour service tests. This work is of interest to stakeholders, including field owners, EPCI contractors, standardization committees and consultants.

Abstract
The Lingshui25-1 gas field is located in the northern sea area of Qiongdongnan Basin, and the water depth is 850m ~ 1000m. The gas production from the LS25-1 field is facilitated through a 115 km long, 20-inch export pipeline, which ties back to a shallow jacket platform. This paper delineates the design and analytical approaches employed for the 20-inch export multiphase pipeline, addressing significant design and installation challenges. These include pipeline route optimization, pipe-soil interaction analysis, bottom roughness and span fatigue analysis, and a composite fatigue assessment encompassing VIV span fatigue, thermal fatigue, and slugging fatigue at subsea scarp locations. As of October 2023, the pipeline has been successfully laid, accompanied by subsequent post-installation surveys. This paper additionally elucidates the installation processes and post-survey span conditions, contextualized within the realm of subsea engineering.
