Assessing the Technical Specifications of Predictive Maintenance: A Case Study of Centrifugal Compressor
(Peer reviewed; Journal article, 2021-02)Dependability analyses in the design phase are common in IEC 60300 standards to assess the reliability, risk, maintainability, and maintenance supportability of specific physical assets. Reliability and risk assessment ... -
Development of One-Part Rock-Based Geopolymers for Downhole Cementing Applications
(Peer reviewed; Journal article, 2023-10)The use of geopolymers as a full replacement for cement in oil well cementing applications requires the development of not only environmentally friendly but also user-friendly cementitious materials. This study aims to ... -
Lifetime Benefit Analysis of Intelligent Maintenance: Simulation Modeling Approach and Industrial Case Study
(Peer reviewed; Journal article, 2021-04)The introduction of Industry 4.0 is expected to revolutionize current maintenance practices by reaching new levels of predictive (detection, diagnosis, and prognosis processes) and prescriptive maintenance analytics. In ... -
Prediction of Oil Recovery Factor in Stratified Reservoirs after Immiscible Water-Alternating-Gas Injection based on PSO-, GSA-, GWO-, and GA-LSSVM
(Peer reviewed; Journal article, 2022)In this study, we solve the challenge of predicting oil recovery factor (RF) in layered heterogeneous reservoirs after 1.5 pore volumes of water-, gas- or water-alternating-gas (WAG) injection. A dataset of ~2500 reservoir ... -
Rheological Compatibility of a Hardening Spacer Fluid and Oil-based Drilling Fluid
(Peer reviewed; Journal article, 2023-08)In the placement process of the cement slurry, treatment fluids such as the spacer are pumped ahead of the cementitious slurry to minimize the contamination of the slurry by drilling fluid and ensure superior bonding to ... -
A sequential decision and data analytics framework for maximizing value and reliability of CO2 storage monitoring
(Peer reviewed; Journal article, 2021-12)Carbon capture and sequestration (carbon capture and storage or CCS) represents a unique potential strategy that can minimize CO2 emissions in the atmosphere, and it creates a pathway toward a neutral carbon balance, which ... -
Synthesis and Investigation of Polymers of 2‑Methacrylamido-caprolactam as Kinetic Hydrate Inhibitors
(Peer reviewed; Journal article, 2020-05)Poly(N-vinylcaprolactam) (PVCap) and related copolymers have been used as kinetic hydrate inhibitors (KHIs) for over 25 years to combat gas hydrate formation in oil and gas field production flow lines. The caprolactam ... -
Valuation of proved vs. probable oil and gas reserves
(Journal article; Peer reviewed, 2017-09)Oil and gas reserves are the most important assets of oil and gas companies. A source of confusion for investors in oil companies, is that reserves quantities and values are uncertain estimates. Reserves are typically ... -
Zonal Isolation Material for Low-Temperature Shallow-Depth Application: Evaluation of Early Properties Development
(Peer reviewed; Journal article, 2023)Shallow-depth cementing presents unique challenges due to its low temperature and low pore pressure characteristic. The curing process of the cementitious material is typically prolonged at low temperatures resulting in a ...
