Reactive Mass Transport model results - Chloride ingress in Norway

Datasets containing modelling results from a numerical investigation of chloride ingress in Norwegian conditions for various binder combinations. - Comparison of model results with case-studies (experimental data) - Parameter study - Regression models Dataset containing modelling results from a numerical investigation of chloride ingress in Norwegian conditions for various binder combinations. The dataset contains 90 model runs for a 200-year service-life, for 18 cement blends (see report below). Each blend was simulated with five different tortuosity factor values: 1/5000, 1/1000, 1/500, 1/200, 1/100. The model input parameters and dataset details are described in the report: Marcos-Meson V.

Quantitative Evaluation of Liquid Permeability in Cracked Oilwell Cement Sheaths

Understanding the consequences of cracking in oilwell cement sheaths is crucial to evaluating the leakage scenarios that can lead to sustained casing pressure. However, the theoretical equations commonly used to estimate flows and permeabilities tend to overestimate actual flow rates through cracks, primarily due to the omission of key factors such as crack tortuosity, surface roughness, and self-healing processes. Therefore, experimental methods are required to quantify the influence of these factors and define “empirical reduction factors.” Because each material exhibits its own unique effects on flow behavior, empirical reduction factors must be determined for each specific material, including oilwell cement. This paper presents a comprehensive procedure for systematically measuring flows, determining permeabilities, and evaluating self-healing processes in deliberately cracked cement specimens with controlled crack widths. The procedure considers pressure gradients and crack widths relevant to oilwell conditions aiming to contribute to the development of more accurate models and simulations for cemented oil wells.</p
