possible to investigate the size, age, and geographical distribution of the buried volcanoes from multi-beam, single-, and multi-channel seismic data collected beneath the South China Sea (SCS) Xisha massif, which we argue is a continental ribbon. These data made it evident that the Middle Miocene volcanoes frequently generated massive volcanic fields that erupted along the rift fault zones, in contrast to the Early Miocene volcanoes, which typically built clusters of small-volume volcanic cones in the half-graben. Details include the presence of numerous volcanoes above and to the side of the dome-shaped main edifice that constitutes the middle Miocene volcanic field. Intrusive sills beneath volcanoes are isolated and have a dispersed distribution pattern at different levels, whereas dykes beneath volcanoes are numerous and have vertical zones of disruption (VZD) that connect to underlying faults or extend through the sediments to the crust. The relationship between the volcanoes and intrusions suggests that shallow igneous plumbing systems within the Xisha massif are most likely dyke domains. The Xisha massif has favorable conditions, including a relatively thin sedimentary sequence over a slightly extended continental crust (2028 km) that might provide enough magma pressure for an igneous plumbing system that is primarily fed by dykes. Additionally, rifted faults in the upper crust and possibly sub-vertical foliations in the basement rock mass were thought to be viable routes for magma transport vertically. We emphasize the importance of crustal structure on the continental ribbon in controlling igneous plumbing styles and the distribution of post-rift volcanic systems along magma-poor continental margins, including crustal thickness, pre-existing faults, heterogeneous basement, and sediments.

Seismic 3D full-horizon tracking based on knowledge graph to represent the stratigraphic sequence relationship

Seismic 3D full-horizon tracking is a fundamental and crucial step in sequence analysis and reservoir modeling. Existing automatic full-horizon tracking approaches lack effective methods for representing the stratigraphic sequence relationships in seismic data. However, the inability to represent the stratigraphic sequence relationships fully and accurately makes it challenging to address discontinuous areas affected by faults and unconformities. To address this issue effectively, we propose a knowledge graph representing the stratigraphic sequence relationship, which enables the simultaneous extraction of all horizon surfaces once the stratigraphic distribution of the seismic data is obtained. In this method, horizon patches are generated, and the fault attribute is calculated, followed by the construction of an initial knowledge graph that characterizes the overall distribution of both horizon patches and faults. The initial knowledge graph comprises nodes and edges. Here, the nodes represent horizon patches, and their attributes cover the geographical location information of the patches and faults. Simultaneously, edges represent the relationship between horizon patches, including the stratigraphic sequence relationship, and their attributes illustrate the potential of connecting these patches. Furthermore, we developed a multi-layer knowledge graph based on the point set topology to fuse the nodes. This allows for continuous merging of horizon patches to obtain horizon surfaces across discontinuities with the constraints of fault attributes and stratigraphic sequence relationships in 3D space. Both synthetic and field examples demonstrated that the proposed method can effectively represent the stratigraphic sequence relationships and accurately track horizons dislocated in discontinuous areas with faults and unconformities.

Abstract Multilateral completions increase reservoir exposure while reducing the investment by minimizing the equipment and the installation time compared to two individual wells. multilaterals (MLT) wells in the Northwest shelf of Australia have been installed for over a decade now. An overview of these operations, well architectures, technology evolution, reliability and efficiency are discussed in the paper. This paper reviews the custom solutions developed throughout the past decade illustrating not only the industry maturity, but also specific advancements in multilateral completion technology that were pioneered in the region. The study is focused on subsea multilateral campaigns, where multiple global and regional first installations took place in mature fields. Operational and technological advancements were implemented throughout the campaigns based on lessons learned. Inaugural deployments featured pre-milled windows, inner-string based liner orientation methods, and a dedicated cleanout trip. Operational modifications and new technologies were introduced to significantly reduce installation time and costs. The first multilateral installation completed in Australia by the service company was in 2006. Over several different projects with different operators in Australia, one particular system was the basis for successfully deployed variants, delivering over thirty productive laterals where mechanical and hydraulic integrity was achieved at each junction. The study demonstrates how the continual advancement of technologies and efficiencies resulted in a reduction of MLT installation time by nearly half since the first system was installed. This encompasses not only new installations, but also infill re-entry applications as well. Additional cost reductions were realized with the introduction of trilateral well construction. This was accomplished by addressing and mitigating risks inherent to adding more junctions to the configuration. This case study focuses on the offshore MLT well construction techniques and demonstrates how introducing both technology and efficiency changes can drive optimized time and costs amid oil price uncertainty. This paper also provides insight as to methodology for continually improving reliability of MLT installations, even while well complexity increases.

Abstract The Jansz-Io field is part of the ‘Greater Gorgon’ project, situated approximately 120km offshore the northwest coast in the Northern Carnarvon Basin offshore Western Australia. This study presents a two-part workflow for determining petrophysical and grain-size related properties of the late Jurassic Jansz Sandstone in the Jansz-Io Field. This field contains highly variable clays and cements distributed both vertically and spatially due to bioturbation and diagenetic processes. The relationship between saturation and pore structure, important for reservoir evaluation and modeling, is not well understood. The objective of the study is to use class-based machine learning (CbML) and nuclear magnetic resonance (NMR) pore-to-production workflows to improve the understanding of the reservoir properties. This will also reduce uncertainty in gas initially in place (GIIP) and estimated ultimate recovery (EUR) during static and dynamic modeling workflows. The first part of the workflow involves applying CbML to determine petrophysical properties. CbML was used to classify well logs into facies based on rock types. The resulting classification was used to determine core-calibrated continuous petrophysical properties in all wells. In the second part, novel NMR pore-to-production workflows were used to determine grainsize related properties. NMR data from 19 wells were normalized against different acquisition technologies, vendors, and conveyances using factor analysis and fluid substitution methods, to determine textural facies, effective porosity/water saturation, and grain-size distribution across the field. The workflow comprising CbML and NMR pore-to-production methodologies shows how AI/ML can assist alongside conventional workflows to maximize the return on investment of measurement acquisition. The results show that the fluidsubstituted NMR distribution and grain-size distribution by textural facies is integral to understanding the relationship between permeability, porosity, water saturation, and grain size. Insights from this study are being used to update the geological deposition model to reduce uncertainty in GIIP and EUR during static and dynamic modeling workflows. The integrated workflow enables the determination of continuous core-calibrated properties required for not only petrophysical evaluation but also for geological and reservoir modeling to optimize completions and production. The significance of the study lies in its ability to improve the understanding of reservoir properties and reduce uncertainty in GIIP and EUR, leading to more accurate reservoir modeling and optimized production. The novelty of the study lies in the combination of CbML and NMR pore-to-production methodologies to determine petrophysical and grain-size related properties of the Jansz-Io Field.

Early and Accurate Quantification of Mercury Contaminant Levels in Gas-Condensate Reservoirs

Abstract Mercury is a trace contaminant present in natural gas and condensates. Production facilities must be designed to remove anticipated mercury contamination in natural gas streams to meet process safety, health, environmental, regulatory and sales requirements. Early and accurate quantification of mercury concentration levels is therefore critical for the safe and economic development of gas resources. This paper introduces reservoir fluid sampling and mercury analysis techniques demonstrated to accurately determine the mercury concentrations in gas-condensate reservoirs. The mercury analysis of reservoir fluid samples acquired with formation sampling tools often misrepresent mercury concentration levels measured later during production. This is due to the highly volatile and reactive nature of mercury, particularly with uncoated metallic surfaces. Laboratory experiments were conducted to develop procedures for accurate and repeatable analysis of mercury concentrations in gas sampling systems. Methane was contaminated with precise concentrations of mercury to facilitate a range of experiments examining both the contamination and scavenging behaviour of mercury in sample chambers. Uncontaminated methane was used as a baseline for background testing sample chambers and laboratory equipment. The experiments identified the presence of residual mercury contamination in sample chambers and laboratory equipment previously exposed to mercury. Cleaning procedures involving the thermal desorption of residual mercury were developed and proven to ensure sampling chambers and laboratory equipment were free of any mercury contamination. Without applying cleaning procedures, any residual mercury would contribute to incorrectly overpredicting the mercury concentrations of reservoir fluids captured in the sample chambers. Subsequent experiments showed that even inert coatings do not completely prevent mercury adsorption to internal metallic chamber walls. Heating the sample chambers to 140 °C was found to release most of the adsorbed mercury back into the gas phase, with a wash procedure required to recover all the remaining mercury and avoid incorrectly underpredicting the actual mercury concentration levels due to scavenging. By implementing a combination of procedural changes, sampling tool modifications and improved measurement techniques, it is possible to acquire reservoir fluid samples with formation sampling tools and accurately measure mercury concentrations representative of that produced from the reservoir. The case study of a gas-condensate field is used to demonstrate that by following the novel techniques introduced in this paper, reservoir fluid samples acquired from wells using formation sampling tools and analysed for mercury can accurately represent the mercury concentration levels measured later during the production phase. Processing facilities can then be appropriately designed or modified early in the field development lifecycle to remove any anticipated mercury in natural gas process streams.

We introduce a novel, computationally efficient model preconditioner, the guided filter, a multi-dimensional, structure-oriented, and edge-preserving filter, with a selfadjoint implementation which does not require a priori knowledge of the structural dip field. We show how to generalize the guided filter to higher dimensions, so that it may be used on typical 3D models and seismic images. We also provide proof that the guided filter is self-adjoint and show applications of the guided filter to seismic reflection tomography.

Joint processing of PP and PS seismic data has the potential to augment our understanding of the subsurface both in terms of structures and rock properties. While significant progress has been made in PS processing, illumination variations of PS reflections are often handled in a simplistic way, which may not be sufficient in complex environments. In this paper, we propose to handle these non-geological variations directly within depth-domain inversion, using point spread functions. We extend the approach of Fletcher et al. (2012) and estimate earth model properties through a joint PP-PS depth-domain inversion scheme accounting for both PP and PS illumination effects. We implement the approach in the context of Kirchhoff depth migration and demonstrate its effectiveness in handling PS illumination effects with a controlled synthetic experiment.
