{"title":"Study on the Oil - Water Relative Permeability Regulation Effect of Pinning Group - Type Black Nanocard in Low - Permeability Heterogeneous Reservoirs","authors":"Ming Qu, Haitong Sun, Jingge Zan, Erlong Yang, Chi Dong, Yuheng Zhao, Tuo Liang, Long Hao","doi":"10.2118/228013-ms","DOIUrl":"https://doi.org/10.2118/228013-ms","url":null,"abstract":"Abstract Medium- and low-permeability reservoirs present significant challenges for conventional water shutoff and profile modification techniques, as well as polymer-based relative permeability modifiers (RPMs), which often hinder oil-phase permeability. In this study, we present the development and evaluation of a novel nanomaterial system, \"PinNano,\" designed to anchor to rock surfaces and achieve long-lasting control over oil–water flow by modulating surface hydrophobicity. PinNano was synthesized by coupling the hydrothermal growth of MoS2 nanosheets (~20 nm) with pulsed laser fragmentation, producing additional sub-10 nm quantum dots that enhance pore compatibility. Sequential surface grafting with polydopamine (PDA) and polypropylene oxides (PPO) endowed the nanosheets with strong interfacial adsorption (\"pinning\") and hydrophobic functionality. The resulting MoS2@PDA-g-PPO material was comprehensively characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and Fourier-transform infrared (FTIR) spectroscopy, confirming successful PDA and PPO modifications. The stability and dispersibility of PinNano suspensions (0.2–1.0 wt%) were evaluated using Turbiscan measurements, revealing optimal stability at 0.2–0.6 wt% (TSI < 1.0). Interfacial tension (IFT) and contact angle tests demonstrated substantial wettability alteration: at 0.6 wt%, IFT with crude oil decreased from approximately 30 mN/m to 2.03 mN/m, and static contact angles reached 146.3°, maintaining capillary resistance in hydrophobic pores and improving residual oil mobilization. Laboratory-on-a-chip and coreflooding experiments further validated PinNano’s efficacy. Chase waterflooding with 0.6 wt% PinNano enhanced sweep efficiency by 61.6% and increased oil recovery by 19.7% compared to primary waterflooding, outperforming amphiphilic MoS2 fluid. Offline nuclear magnetic resonance (NMR) confirmed increased oil displacement in low-permeability zones. Relative permeability measurements indicated that PinNano reduced Krw* by 0.077 at residual-oil saturation and increased Kro* by 0.12 at connate-water saturation, while shape-factor adjustments delayed water breakthrough and enhanced oil mobility. Overall, PinNano offers an innovative, durable RPM strategy for waterflood management in high-water-cut reservoirs. Future work will focus on field pilot trials to translate these laboratory successes into improved oilfield performance and economic returns.","PeriodicalId":128751,"journal":{"name":"SPE Annual Technical Conference and Exhibition","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147904155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Novel Biomimetic Nano-Soft Robot for Integrated CO2 Green Low Energy Consumption Conversion and Storage Via Peridotite Mineralization","authors":"Dan Zhao, Yueliang Liu, Hao Wang, Yi Xia, Zhiyuan Ma, Jixiang Liu, Hong Nie, Zhiqiang Mao, Senyou An, Chenhao Li","doi":"10.2118/227961-ms","DOIUrl":"https://doi.org/10.2118/227961-ms","url":null,"abstract":"Abstract Under the framework of global carbon neutrality and technological innovations, achieving synergistic CO2 conversion-storage systems coupled with high-value chemical co-products holds significant engineering implications. However, CO2 mineralization is an extremely slow kinetic process, and CO2 reduction primarily relies on high-energy electrocatalytic systems. Thus, developing environmentally adaptive functional materials capable of enabling scalable CO2 mineralization with simultaneous value-added product generation under subsurface conditions is of great urgency. This study introduces a stratigraphy-tolerant biomimetic nanogel (nano-soft robot) designed to enhance CO2 hydration kinetics by improving temperature and shear resistance while enhancing catalytic performance.A suite of analytical techniques, including SEM, TGA and XRD elucidated the diffusion pathways of mineral precursors and the crystallization nucleation mechanisms of peridotite carbonate minerals. This study elucidates the mechanisms underlying biomimetic nanogel-enabled peridotite CO2 reduction for ethane/ethylene/propane generation, culminating in the innovative development of integrated CO2 mineralization-reduction coupling technology in peridotites. The experimental results demonstrate successful construction of a high-temperature-resistant biomimetic nano-soft robot with cobalt (Co) as the catalytic active center. XPS and SEM analysis demonstrate that the nanogel possesses a unique structure in which organic crystals are encapsulated within a nanogel matrix. In CO2 hydration experiments, the nano-robot exhibited high catalytic efficiency, reducing the system pH to 6.30 within 300 seconds at a 20 mg dosage. The synthesized catalyst exhibits excellent viscoelastic properties, with a storage modulus (G′) exceeding 10⁴ Pa, indicating outstanding mechanical stability under reservoir conditions. Importantly, this flexible nanozyme demonstrates exceptional thermal resistance, far exceeding the thermal deactivation threshold (45°C) of conventional carbonic anhydrases, while ZIF-67 MOF achieved only pH 6.63 under identical conditions. GC analysis confirmed H2 generation and CO2 reduction, yielding 2800 ppm C2-C3 hydrocarbons during the peridotite-hosted in situ CO2 mineralization-reduction reaction mediated by 20 mg biomimetic nanogel catalyst under conditions of 10 MPa and 40°C for 3 days. The temperature-adaptive viscoelastic matrix further ensures structural integrity under hydrothermal conditions, enabling sustained catalytic activity through dynamic self-reconfiguration. These findings establish a novel CO2 mineralization-reduction coupling technology in peridotite, accelerating carbonation kinetics and hydrocarbon production for carbon sequestration. While realizing the strategic goal of carbon neutrality, we aim to produce green high-value-added chemical products through integrated processes and promote the resource-based utilization of CO2.","PeriodicalId":128751,"journal":{"name":"SPE Annual Technical Conference and Exhibition","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147382129","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Advanced Multi-Lateral Monitoring Using Intelligent Inflow Tracers with Production Log Comparison in a Carbonate Reservoir","authors":"Hassan J. Alshaer, M. Almansouri, M. Al-Harbi, E.. Leung, Mohammed Alghamdi, Latifa Al Haji, Olaf Huseby","doi":"10.2118/220949-ms","DOIUrl":"https://doi.org/10.2118/220949-ms","url":null,"abstract":"Abstract Production logging tools (PLT) have been the incumbent of downhole monitoring technology for decades. These tools, often used in conjunction with tractors in extended laterals, pinpoint the locations of water or gas breakthrough and map the flow profile across producing zones. However, the logistics of scheduling and mobilizing production logging equipment and personnel are cumbersome and time-consuming. Acknowledging these challenges, alternative downhole monitoring technologies had to be explored to circumvent the limitations associated with PLT monitoring. The innovative approach involved deploying a smart multi-lateral well system with inflow control valves (ICV), annular and tubing pressure and temperature sensors. In addition, unique oil and water inflow tracers were installed to enable monitoring without intervention risks, with limited personnel and costs. The sensors were strategically placed near the junctions in the mother-bore. The primary objective was to conduct a blind comparison of inflow tracing and conventional production logging, assessing tracer applicability in a complex well and reservoir environment. The chosen well, a penta-lateral with extended reach, completed across multiple zones with different pressure regimes and high H2S, provided a challenging setting for this comparison. The study implemented monitoring campaigns under varied rate conditions, with and without PLT, to evaluate the downhole technologies’ performance. This paper presents novel and patented modeling methods designed to accurately interpret inflow tracer responses, especially where standard modelling approaches fall short. The blind comparison initiative, encompassing six distinct monitoring campaigns across different production scenarios in a carbonate oil reservoir, aimed to track lateral performance over time. The findings indicate that inflow tracer interpretations are comparably similar to PLT results, validating tracer methodology as a means to enhance and simplify well monitoring in complex well settings.","PeriodicalId":128751,"journal":{"name":"SPE Annual Technical Conference and Exhibition","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147917797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
