Abstract
Monitoring and surveillance (M&S) is one of the key requisites for assessing the effectiveness and success of any onshore and offshore CCS/CCUS project. It will help understand, track, monitor, and predict the injectant plume migration, flow paths, and breakthrough times. The M&S helps in quantifying sequestered injected gas and any inadvertent leakage. It provides a good understanding of the remaining oil saturation (ROS) and its distribution in the reservoir.
In this manuscript, a comprehensive monitoring and surveillance (M&S) program is developed and discussed for the onshore and offshore CCUS/CCS projects. A range of monitoring techniques are available for the CO2 geological storage in onshore and offshore reservoirs. The advanced M&S plan incorporates conventional, advanced, and emerging novel technologies for wellbore and inter-well measurements. Both deep focused (providing surveillance of the reservoir and deeper overburden) and shallow-focused (providing surveillance of the near seabed, seabed and water column). These include advanced time-lapse pulsed neutron, resistivity, diffusion logs, and bore-hole gravity measurements, cross-well geophysical measurements, water and gas tracers, geochemical, compositional and soil gas analyses, and 4D seismic and surface gravity measurements.
Results from monitoring and surveillance technologies provide a better understanding of the reservoir dynamics within the subject area. The results can be used to refine the reservoir simulation model and fine tune its parameters. This paper reviews some proven best practices and draws examples from ongoing projects and related novel technologies being deployed for onshore and offshore reservoirs. It will then look at the new horizon for M&S technologies for onshore and offshore CCS and CCUS projects.

Abstract
The current practices in oil & Gas industry lack digitalization in the field of Sand Management. A recently developed simulator was identified and employed to conduct a pilot study and hence compare the metal loss and choke health data with the real field thickness sensor and choke inspection data. The objective of the Study was to carry out an analysis of the current challenges in the Sand Management portfolio of the organization and to present solutions via the software.
The challenges included: Identifying the Total Metal Loss & Deposition hotspots for entire field.Development of a robust strategy to manage production chokes.Study of corrosion effects on erosion due to sand.The obtained results to be in accordance with the actual field conditions.Provide recommendations for efficient sand management and cost savings.
A thorough Sand Management study inclusive of Total Metal Loss (Erosion + Corrosion), Depositional and Handling risks related to the Well and Facility were studied using the software's advanced sand travel logics, unique features & multi-level sensitivity analysis.
The main Outputs from the study were: Metal Loss Hotspots & their values for all the facility pipelines were identified, calibrated and Validated.The study provided road maps to answer the uncertainties related to the incoming Particle Size Distribution (PSD), incoming and surface Sand Concentration through work-flows and sensitivity analysis.A Choke Management workflow was displayed which not only simulates the current condition of the choke but can also predicts future failures and help in optimizing choke for longevity.Component Life & Minimum Allowable wall thickness calculations. At the end of this phase, the results were presented & validated by the Petronas Technical team.
As a result of the above study, the benefits of the software's accurate predictions were: Cost & Time Saving: the frequency of sand sensor data collection can be increased. Also, since the hotspots have already been pin-pointed by the simulator, there is no need to conduct the metal loss sensor survey for the entire pipeline, it can be focused to the hotspots only.Carbon Footprint Reduction: Higher frequency would result in lower human intervention.The metal Loss and health data can be visualized on a real-time basis hence a more pro-active approach can be applied to tackle the integrity issues.
Substantial increase in revenue and reduction in expenditure can be done by predicting and mitigating the sand related risks. This Simulator can cover the entire cradle to grave period of a field & this new outlook of sand management would be highly beneficial to industry.
Enabling Ecosystem Based Management: New Ways to Conduct Deep Sea Minerals Exploration

Abstract
The Cook Islands (CI) possesses within its Exclusive Economic Zone (EEZ) a massive field of polymetallic nodules representing one of the world's largest undeveloped cobalt deposits, along with large quantities of other metals critical to achieving global energy transition targets. In February of 2022 the Seabed Minerals Authority (SBMA) of the CI granted licenses to three companies to conduct nodule exploration programs. This paper describes the process adopted by Moana Minerals, one of the license holders, to define new ways of conducting exploration which are focused on addressing the greatest challenge to Deep Sea Mining (DSM) development – that of securing the social license to advance to eventual mining of the resources.
While it is generally true for any DSM project, obtaining license to operate within the EEZ of a sovereign nation requires even more focus on socio-economic and cultural concerns. Hence Moana Minerals invested even before exploration license award in the completion of an Environmental and Social Impact Assessment (ESIA) scoping study. This exercise helped to define the key questions and concerns, the range of stakeholders in the ESIA process, and began to construct the Ecosystem Based Model which is the heart of our ESIA program. We describe our employment of the increasingly adopted best practice of Ecosystem Based Management (EBM), which considers the entire ecosystem and its services, and the complex associated interactions for a "whole of system" approach. We discuss how this model is used to help communicate relationships between potential stressors associated with seabed mining and ecosystem responses, as well as how it is used to identify thresholds and guide development and adaptation of ecosystem management approaches. Given the challenges of the remoteness of the Cook Islands, limited exploration assets in the region, and ongoing supply chain delays and limitations, our early analysis of how best to execute an EBM-based program concluded that a dedicated research vessel properly outfitted with a full suite of scientific gear would be key to success. We describe our program to economically develop such an exploration system through repurposing an offshore support vessel, with an aim towards maximum suitability for Cook Islands-based exploration and other deep sea exploration work in the region as well as other potential high value regional applications. Finally, we discuss operations to date using this critical exploration-enabling asset.

Published: April 2023

Abstract
Due to their non-linear bending response, low bending stiffness and potentially high axial expansion coefficients, buried unbonded flexible pipes can be susceptible to Upheaval Buckling (UHB). The traditional industry approach is to prevent UHB by providing sufficient download to limit upwards movement of the pipe to very small levels (normally within the mobilisation distance of the soil). Since unbonded flexible pipes offer little resistance to bending, the required download to prevent UHB of unbonded flexible pipes can be significant resulting in prohibitive rock-dump requirements. However, by design, unbonded flexible pipes can accommodate large bending deformations without compromising the cross-sectional integrity of the pipe. The objective of this paper is to propose an approach which takes advantage of the pipes capability to accommodate large deformations and to minimize download requirements.
This paper presents a comprehensive literature review of the state-of-the-art methods currently adopted in industry for the assessment of UHB of buried unbonded flexible pipelines. An alternative approach which permits significant upwards movement of the flexible pipe, taking advantage of the pipes ability to accommodate such movements, is also presented. A comparison of the potential failure modes, mechanisms and consequences associated with these approaches are studied and acceptance criteria are proposed. Parametric finite element analysis studies are performed to compare the flexible pipe behaviour and download requirements using the traditional approach and the proposed alternative approach.
This paper presents case studies which demonstrate that significant savings in the volume of rock-dump can be safely made when permitting large deformations when compared to the traditional UHB prevention approach.

Abstract
Subsea fields characterized by multiphase reservoir, deep wells, and pipeline-riser setups, are prone to slugging. Sustained slugs arriving at surface facilities, cause several operational challenges leading to reduced production or field shutdown. Reliable forecasting of slugging behavior is crucial in mitigating slugging and optimizing field behavior. The goal of this work was to assess potential of deep learning models for slugging forecasting and production optimization. Historical data from several field transmitters which record signatures specific to slugging events was collected and studied. Domain experts classified normal flow, unstable flow, and slug flow conditions in the field based on those data. Several deep learning-based models were trained on the supervised data to generalize correlations for slug identification and forecasting. Experiments were conducted on the labelled data to identify best suitable prediction model. A state-of-the-art temporal fusion transformer model was selected for time series forecasting based on experiments.
The real-time and historical data possess noisy signals and skewed distribution depending upon frequency of slug events. The deep learning model was found to overcome these challenges and successfully learn the complex interaction in time between various field variables and correlate with slugging patterns. Not only was the model able to classify between slug and no-slug events, but it was further able to forecast slugging critical variables such as slug frequency, amplitude, slug volume, etc. The selected model outperformed traditional statistical models such as Non-Parametric Time Series (NPTS) and other deep neural network models such as DeepAR, and Simple Feed Forward. The model was able to match the flow behavior during slugging events with continuously improved performance after multiple training exercises on additional data. This novel solution can be used for active monitoring of slugging conditions in field, generating alerts and provide forecasting on slug critical information.
Visibility in the future will enable understanding of slugging behavior and empower the operators to take proactive mitigation measures based on predicted slugging signatures. This will improve the operational efficiency and hence minimize the negative impact of slugging on productivity, asset integrity and the environment.

Published: April 2023

Abstract
As offshore wind generation activities continue to expand in the United States, there is a growing need for more efficient, optimized, and reliable analysis of the foundation structures that support Wind Turbine Generators (WTGs). This paper aims to provide a comparison of coupled and uncoupled analysis methodologies for the design of offshore WTG foundation structures under complex dynamic loading from turbine operation and sea states. The focus is on an integrated turbine, turbine tower, and foundation model, which is essential for understanding the behavior of the entire system under various loading conditions. The goal of this paper is to provide insight into the strengths and limitations of two different analysis approaches, coupled and uncoupled, with the aim of helping engineers and designers make more informed decisions when it comes to the design and construction of offshore WTG foundation structures.
In this research, an integrated substructure, turbine, and tower model was developed to support the offshore wind turbine. Both coupled and uncoupled dynamic analysis methods were applied to the analysis models. The dynamic turbine loads were calculated using wind turbine information from the National Renewable Energy Laboratory (NREL). Modal analyses were performed to determine the mode shapes and natural frequencies as well as dynamic time history analysis to determine hydrodynamic forces on the support structure. The forces and displacements at the interface joint were then compared to evaluate the difference in behavior between the uncoupled and coupled solutions.
This study aims to fill a gap in the current literature by comparing coupled and uncoupled analysis methodologies specific to the integrated model of WTG foundation structure. The paper presents a side-by-side comparison of the coupled and uncoupled analysis using SACS analysis software by Bentley and the OpenFAST program by NREL. SACS is one of the most widely used software packages for the design and analysis of offshore structures in the United States.
The findings from these case studies on monopile and jacket foundation types offer a deeper understanding of the distinctions and similarities between coupled and uncoupled analysis of the integrated structure model. This paper presents the conclusions from the study and summarize the key observations to assist engineers in creating simulation models and analyzing WTG foundation structures. These observations will aid in comprehending the complexities of the dynamic behavior of the WTG foundation structure under combined environmental and turbine loading.
Optimization of Well Completion Strategy for Double Displacement Process (DDP) and Water Alternating Gas (WAG) Injection in a Dipping Stratified Reservoir
Authors: Ngo Vuong Thanh , James Lesley A 
Published: April 2023

Abstract
This study assesses how zone-by-zone completion strategy which including top-down & bottom-up mechanisms affect the performance of the double displacement process (DDP) and water alternating gas (WAG) up-dip and down-dip. It further seeks to develop an optimal zone-by-zone completion strategy to overcome the gas override problem and increase oil recovery in a dipping stratified reservoir. The impact of connection transmissibility on completion strategies in a dipping stratified reservoir is also investigated.
The research was conducted on a stratified block model reservoir with dimension 4000 m × 1000 m × 80 m and is divided into four main reservoir zones in Z direction. Zones are separated from each other by a thin shale bed with thickness of 0.2 m. The communication between reservoir zones and shale beds have level of 0, 0.1, 0.01 relating to completely sealing shale, leaky shale and completely open shale. Well completion strategies simulated included all zones injecting and producing, top-down and bottom-up. The simulation begins with waterflooding to obtain 95% water cut, then the performance of DDP, WAG up-dip, and WAG down-dip with the various completion strategies were simulated.
The results prove that zone-by-zone completion strategy is a successful way to overcome gas override and improve vertical conformance with WAG injection in a stratified reservoir to maximize oil recovery from the offshore field in East Canada. With zone-by-zone completion strategy, the recovery factor of WAG up-dip increased 0.8% more than the all-zone injecting and producing scheme. The results also identified bottom-up was effective completion strategy for WAG up-dip in stratified reservoirs without zonal communication and top-down was a successful completion strategy for communicating stratified reservoirs with 0.01 level of connection transmissibility with WAG up-dip and without zonal communication with WAG down-dip. DDP and WAG are considered as potentially effective enhanced oil recovery methods for offshore reservoir. However, most of studies be conducted on laboratory and reservoir simulation scale, and focus on operation parameters such as WAG ratio, WAG cycle, slug size. Our understanding is that this is the first study on the effect of top-down and bottom-up completion strategies to the performance of DDP and WAG in pilot stage on a dipping stratified reservoir block model.
