Published: October 2023

Abstract

Objectives/Scope
This work aims to develop a systematic methodology for the optimisation of maintenance inventory management, independent of industry or project lifecycle stages (greenfield and brownfield). The objective is to enable operators to integrate the use of ‘lite’ dynamic optimisation and recommender systems into existing or proposed business processes, systems, and ways of working. Additionally, this work aims to explore methodologies for enabling the sustainment and ongoing improvement of such systems within a complex asset management context.

Methods, Procedures, Process
Leveraging Natural Language Processing (NLP) algorithms to improve the speed and accuracy of identifying and cataloguing interchangeable materials and classifying failure modes from operational maintenance data. These algorithms enable comparative analytics across and within facilities, including reliability modelling, material demand modelling, and production vs maintenance optimisation models. This approach leverages foundational maintenance build analyses outputs such as FMECA, RCM, and cataloguing.

Results, Observations, Conclusions
Results highlight the ability of these ‘lite’ dynamic optimisation and recommender models to be deployed at speed and to be sustained, whilst enabling significant value gains, across production uptime, maintenance cost, and safety, at low cost (particularly when compared to large software systems). Such systems are also designed to be user and use case centric, enabling them to be dynamic and easy to configure. A recent implementation of our data-driven approach has led to 40% reduction in inventory value while increasing the critical spare materials to enable high asset availability.

Novel/Additive Information
Advanced text processing algorithms used in conjunction with advanced maintenance and reliability modelling techniques, packaged within ‘lite’ systems. These systems are also live and provide recommendations at a frequency suitable to the operator's business process requirements.
Using Drones to Improve Project Construction Monitoring
Authors: Shawky Mohamed 
Published: October 2023

The advent of technology has brought forth substantial changes in various industries, significantly transforming their operational capabilities and enhancing their productivity. A notable innovation shaping the future of many sectors is the use of Unmanned Aerial Vehicles (UAVs), commonly referred to as drones. Among various fields, the construction industry, and in particular the oil & gas sector, has significantly benefited from integrating drone technology, especially in project construction monitoring [1].

Overview of Project Construction Monitoring in the Oil & Gas Industry
In the oil & gas industry, project construction monitoring plays a crucial role, ensuring that projects progress as planned and any issues are promptly identified and addressed. These monitoring processes traditionally involve numerous on-site workers, heavy machinery, and extensive time and resources [2]. However, the industry's dynamic environment, characterized by sprawling sites, hazardous conditions, and complex projects, necessitates a more efficient approach to construction monitoring. In response to these challenges, the industry is increasingly turning to drone technology [3].

Importance of Efficient Project Construction Monitoring
Efficient construction monitoring is pivotal for the timely completion of projects, maintaining budget constraints, and ensuring safety standards. Any delays or cost overruns in large-scale oil & gas projects can have substantial financial and operational implications. Moreover, efficient monitoring can help identify potential risks and issues early, allowing for preventative measures to be implemented, reducing the likelihood of accidents and promoting a safer working environment [4].

Published: October 2023

AbstractThis paper presents a novel approach to reducing the hydraulic breakdown pressure utilizing near-infrared continuous-wave high-power lasers (HPL). The thermo-mechanical and thermo-chemical processes induced by the HPL illumination of the rock above a particular threshold can lead to lower formation strengths, significantly reducing the formation's breaking pressure. This HPL application could improve energy efficiency and reduce the risk of hydraulic fracturing operations.The rock absorbs a portion of the HPL's energy as thermal energy, causing a localized temperature surge, resulting in various physical and chemical changes. The former arises from sharp and fast-developing thermal gradients that generate micro and macro cracks in the formation. The thermal-chemical transformations of the rock include mineral dehydration, dissociation, decomposition, clay collapse, and retorting of organic matter. This electromagnetic-based mechanism has been assessed and proven to effectively reduce breaking pressure for all types of rocks. The process is independent of the rock's stress state and composition. It was evaluated on carbonate, shale, and sandstone formations in the lab. The experimental results guided the development of the first high-power laser field system. The system design incorporates an HPL generator and the optical assembly needed to deliver and manipulate the HPL in the subsurface. The optical assembly includes a subsurface optical tool whose primary function is to control the size, shape, and propagation direction of the HPL beam.The HPL technique was tested on various rock types. Pre- and post-exposure analyses were conducted to evaluate its efficacy. These studies included uniaxial stress tests, unconfined ultrasound velocity measurements, permeability, porosity, composition, grain shapes, contact, and cementation. This investigation provided valuable information about the physical dynamics of the process. The results show that this HPL method could reduce breaking pressure in all rock types. The technique and HPL perforation could create targeted weak spots in the near-wellbore formation, improving the precision of hydraulic fracturing while decreasing its energy intensity, cost, and environmental impact.

Published: October 2023

Abstract
Foam is one of the most promising techniques to reduce gas mobility in subsurface formations. Foamed-gas injection can reduce the mobility of gas by increasing the volume of trapped gas in the liquid phase, thereby increasing its apparent viscosity to reduce the relative permeability. However, the poor stability of foam generated by surfactants at reservoir conditions is a challenge that hinders the effectiveness of the foam flooding. The mixture of surfactant and nanoparticles can offer a potential solution to enhance foam stability. The objective of this study is to evaluate how such new mixtures formulated in this work enhances the foam stability.
Foam analysis using foam analyzer equipment and nanoparticle size measurements, were conducted to capture the foam stability and strength for an anionic surfactant and the mixture of an anionic surfactant and surface modified silica nanoparticles. Also, transmission electron microscopy (TEM) was used to assess and visualize the surfactant-nanoparticles interactions using different concentrations of the nanoparticles.
The results from the experiments demonstrated that the use of surfactant combined with nanoparticles enhances the stability and strength of the generated foam when compared to the use of surfactant alone. Comparative images of bubble count and structure of the foams generated showed higher bubble count with smaller bubble sizes when the surfactant is mixed with the nanoparticles. The higher bubble count and smaller bubble sizes are indicative of better, stronger and more stable foams. TEM images showed that the nanoparticles have a tendency to form layered structures in the solutions. This formed layer enhances the film stability by delaying the liquid film rupture.
The combination of nanoparticles and surfactant serves as a new technique for generating stronger and stable foams in gas mobility control applications. This study also provides an important learning point that the selection of the right surfactant and nanoparticle combination are the keys to generate more stable foams.

Abstract
Enhancing the development of low permeability reservoirs is an important investigation direction for increasing crude oil production in China. Currently, prolonged water or polymer flooding in oil fields exacerbates reservoir heterogeneity. Leading to premature water breakthrough and high water cut significantly hindering efficient oil field development. It is difficult for oilfield production to control the preferential water pathways within the low permeability reservoir and expand the utilization degree of the deep remaining oil. The reservoir control agent represented by polymer gel particles can effectively control the preferential water pathways, expand the sweep range of injected water, and achieve oil field production and efficiency. However, inherent drawbacks of polymer gel particles, such as poor performance of salt resistance and water absorption, high initial hydration expansion rates and low post-expansion rates, present a challenge for in-depth migration and water control. To solve the above problems, in this paper, we prepared a gel particle with excellent salt resistance and water absorption performance, which can delay swelling as well. In order to enhance the salt resistance and water absorption of the gel particles, a zwitterionic monomer methacrylamide propyl-N, N-dimethylpropane sulfonate (with anti-polyelectrolyte effect) with salt resistance performance was synthesized. The method of the composite crosslinking was used to delay the expansion of the gel particles. The salt-resistant and slow-expansion gel particles with low primary expansion ratio and higher secondary expansion performance were prepared and optimized. The results showed that the preparation of the particles was successful and the mechanism of delaying expansion was revealed. The deep migration and deep plugging performance of the gel particles were further studied through a multi-point pressure measurement experiment of sand pipe. This paper solves the problems of poor salt resistance, water absorption ability and fast expansion speed of polymer gel particles. The results shown here provide theoretical guidance and technical support for in-depth water control of low permeability reservoirs.
Sustainability in Drilling Operations Using Zero Liquid Discharge Wastewater

Published: October 2023

Abstract
Produced water is generated from subsurface reservoirs during oil and gas extraction. Zero liquid discharge (ZLD) produced water desalination technology generates clean low salinity water from hypersaline produced water with 80 to 90% recovery efficiency. The minimal volumes of salt laden reject streams discharged from ZLD desalination plant could be recycled for mineral recovery or drilling applications to achieve 100% circular economy. Such applicability of wastewater streams for potential reuse in drilling applications is evaluated in this study in order to avoid waste disposal into the environment and promote sustainability.
We have tested and demonstrated the applicability of ZLD reject water as a makeup fluid for preparing water-based mud systems. The total dissolved salt of ZLD reject water is around 360000 ppm. The conventional water-based mud additives have limitations in terms of salt tolerance. Therefore, it is essential to study the conventional water-based mud additives to ensure the compatibility in such high saline environment.
Three basic water formulations with viscosifier, fluid loss control and pH controlling additive are prepared using 100 % regular fresh water, 100% ZLD reject water and 50:50 mixture of fresh water and ZLD reject water. Mud formulations were made with bentonite and xanthan gum as viscosifiers. The mud samples have been subjected to routine mud analysis such as hot rolling, rheological and filtration control tests. Initial screening was done for choosing the viscosifier. Formulations made with Bentonite as a viscosifier failed to provide viscosity and solids suspension property for the muds formulated using 100% reject water and 50:50 mixture of fresh water and ZLD reject water. This is due to the high salt intolerance of Bentonite. Formulation of 50:50 mixture of fresh water and reject water using Xanthan Gum as viscosifier resulted in acceptable properties such as rheology and filtration control, whereas poor rheological and filtration control properties are observed for 100% reject water.
Further testing was conducted by adding more additives such as bridging materials, weighting materials and drill solids contaminants to the basic mud formulation having 50:50 mixture of fresh water and reject water. The results for the mud that was hot rolled at 212 °F and 500 psi showed acceptable rheological and filtration control properties. Excellent mud suspension property has been observed with no solids settling or separation even after 24 h. These interesting laboratory results demonstrate that the waste reject water obtained from ZLD produced water desalination plant could be an alternate to fresh water currently used in mud preparation.
The ZLD waste reject water was successfully used to formulate water-based mud to achieve 100% circular economy. This novel development paves the way to effectively recycle wastewater for drilling applications to conserve fresh water and promote environmental sustainability in drilling operations.

Abstract
Clay bearing shale formations tend to swell upon contact with water-based drilling fluid. The migration of hydrogen ions into the nano-spacing of shale platelets is mainly responsible for its disintegration and swelling. To mitigate the clay swelling problem, various shale stabilization materials are added in the water-based muds (WBMs). Before adding these additives, it is crucial to understand their physical and chemical interactions with clay minerals as well as within fluid. In this study, Taro Root Mucilage (TRM) is used as a green chemical in WBM to decrease the shale swelling characteristics. Taro root was boiled in distilled water at 40°C for 24 h and mucilage was prepared, which was characterized by FTIR and XRD pattern. It was then made part of a mud system, which then interacted with the shale sample collected from the western zone of Pakistan. Moreover, this mucilage was compared with sodium alginate mud system, a biopolymer commonly used in industry. The results of the experimental studies showed that TRM appreciably reduces clay swelling characteristics compared with the distilled water and sodium alginate. Moreover, all the rheological parameters fall under the recommended API range for TRM samples. Furthermore, it was found that the TRM produces a thin filter cake and minimizes fluid loss volume. In addition, during the shale cutting recovery test, 50%, 80% and 100% recoveries were obtained from base mud, whereas 10% and 20% were obtained from TRM based WBM respectively. TRM encapsulates the drilled cutting and preserves it from breaking into smaller fragments. In addition, TRM concentration in drilling mud increases the hydrophobicity of the shale sample. The adsorption of TRM over the surface of shale allows less penetration of water in the nano-spacing of shale structure and improves the shale stability. Hence, the finding in this article implies that TRM can be used as a green and sustainable substitute for traditional clay stabilizers in drilling operations to reduce formation damage. It has all the desired properties that help it to become an alternate solution in the form of a clay swelling inhibitor.
On the Road to Net-Zero Carbon Emissions: A Cementing Emissions Assessment Tool for Quantifying, Evaluating, and Helping Decarbonization

Published: October 2023

Abstract
An important step in decarbonization is using an end-to-end approach to quantify carbon emissions during cementing operations. By careful analysis of the entire cementing operations process, it is then possible to measure and compare carbon emissions at various stages of the operation. Understanding and isolating the main drivers of the carbon emissions footprint enables making better choices and developing best alternatives with lower environmental impact.
The methodology considers the lifecycle assessment of cement from quarry extraction to well abandonment, and includes steps such as manufacturing of raw materials, transportation and logistics, and operations in the field. For these stages, careful quantification of emissions is performed based on the manufacturer's carbon emissions of cementing products, transportation (distance and means) to the bulk plant and rig site, and equipment-related emissions such as blending and pumping units. In some cases, when assessing the footprint of different technologies, a sensitivity analysis can be carried out to compare the operation-related emissions based on a field case.
Using an assessment tool during key cementing operations allows for identifying the main contributors to greenhouse gas (GHG) emissions. In most cases, the embodied carbon in the cement slurry itself outweighs the operational emissions (on an average, one ton of CO2e is emitted for every ton of Portland cement produced). The embodied carbon of cement systems mainly depends on the data quality of the emission factors of the slurry components. These factors are not yet broadly available and until then, correct proxies are needed to perform such studies.
Besides the embodied carbon, the assessment tool also quantifies other elements of the cementing operations. Examples of sensitivity analysis will be presented in this paper, covering aspects such as an optimal transportation choice from the supplier location to the implementation site. Furthermore, the tool supports the selection of cementing technologies, integrating performance and larger impacts, such as a change in the well design or elimination of remedial operations during the life of a well.
The cementing emissions planner supplies a platform for consistent and transparent quantification and comparison of cementing technologies supporting an effective environment action. This tool embraces forward-thinking and innovative cementing solutions that help decarbonization in the oil and gas industry in achieving net-zero carbon emissions.

Published: October 2023

Abstract
Understanding the corrosivity of aqueous drilling fluids is essential for more efficient and safer drilling operations. The main factors causing the corrosion of typical aqueous drilling fluids were investigated under laboratory conditions using American Iron and Steel Institute (AISI) 1018 mild carbon steel at 70 degC dynamic flow. Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX), X-ray fluorescence (XRF), and X-ray photoelectron spectroscopy (XPS) analyses were used to characterize the metal microstructure of AISI 1018 steel rotating cylinder electrodes (RCE) and study the changes that occurred during corrosion. The effects of fluid composition, barite weighting agent, and clay contaminant were investigated using RCE to simulate the effect of flow velocity on mild carbon steel corrosion and the effect of dissolved oxygen. Starting with a low salinity chloride-brine base fluid (3% NaCl), the effect of adding various components such as amine-based shale inhibitors, polymeric viscosifiers, and suspended solids on the corrosion of RCE was investigated using various electrochemical techniques such as linear polarization resistance, Tafel analysis, and weight loss measurements. Three additional corrosion factors and chemical additives affecting the corrosion of AISI 1018 mild carbon steel were identified: (1) polymeric viscosifiers, (2) the formation of a mud solids skin on the metal surface, and (3) galvanic corrosion. These factors improve the understanding of the corrosion mechanisms occurring in aqueous drilling fluids and provide valuable insights for the development of effective strategies to reduce corrosion in drilling operations.
Modeling Fractures in a Heterogeneous Carbonate Reservoir Onshore UAE: A Case Study

Published: October 2023

Abstract
A brown field producing from an Upper Cretaceous carbonate reservoir in an elongated anticline is facing water management challenges (increasing water cut, premature water breakthrough), impacting production and recovery. The complexity of heterogeneities encountered in the reservoir (fractures, karst-related features, high permeability dolomitic drains), where depositional settings, diagenesis, and tectonics are intertwined, makes reservoir characterization critical to a successful field development plan. Evidence of dual medium behavior, combined with the presence of fractures from image logs, suggests that fractures may play an important role in reservoir dynamics, and hence need to be modeled appropriately.
In this study, the scope of work was threefold: reviewing the conceptual fracture model in considering the latest data, creating updatable workflows to build discrete fracture networks in commercial geomodeling software, and, ultimately, comparing upscaled properties to well test interpretations representing "fracture" and "matrix" responses. Main fracture sets trend NE-SW, parallel to the anticline axis, and E-W. Two fracture scales have been modeled in the present case study: large features that relate to the deterministic component of the dataset (fracture clusters from image log interpretation and seismic lineaments), and small-scale fractures, stochastically distributed, to reflect the permeability contribution of diffuse fractures connecting deterministic objects.
Calibration to dynamic data is performed by analytical estimation of fracture aperture per fracture orientation set, upscaling to equivalent grid permeability, and iterating until reaching a satisfactory match with the test-derived permeability. The calibration exercise gives a consistent fracture aperture for the two orientation sets tested (NE-SW and E-W).
Fracture modeling was done in parallel to building reservoir matrix properties hence the dynamic calibration considers only fracture permeability. In some cores, measured permeability can reach several Darcies, leading to dual medium behavior without the contribution of fractures. Future work could integrate this analysis with existing sedimentology and reservoir dynamic syntheses to assess the relative impact of high permeability streaks on equivalent permeability and deconvolve it from the role of fractures.
