Abstract:
AbstractIn order to develop improved filters for metal melt filtration, different physical phenomena that take place during depth filtration of liquid metals need to be well understood. Due to the difficult accessibility of the process, the harsh process conditions and the randomness of the typically employed ceramic foam filters, representative experimental investigations are extremely difficult to perform and often provide only integral quantities or selective information. This chapter presents a numerical model for simulating the depth filtration of liquid metal at the pore-scale, i.e., fully resolving the complex filter geometry, which can also accurately handle the curved filter walls. In the model, the velocity and pressure distribution of the melt flow is obtained by the lattice-Boltzmann method and the temperature field is calculated using the finite volume method, while the transport and filtration of the inclusions are predicted by solving the equation of motion for particles in a Lagrangian reference frame. In order to obtain a consistent representation of the curved filter walls for both particle transport and fluid flow, the Euclidean distance field of the filter structures is employed. By comprehensive parametric studies, the sensitivity of the filtration process with respect to various geometric parameters and process conditions is investigated. Therefore, geometries of conventionally manufactured filters, acquired from 3D μCT scanning, as well as computer-generated filter structures are considered. Their performance is assessed by evaluating various effective properties, such as the viscous and inertial permeability and the filtration coefficient. The numerical predictions allow to draw conclusions with respect to the dominant physical mechanisms and are compared with those from simplified physical models, which are shown to be sufficiently accurate for the pre-screening of filters. On the basis of the detailed results, suggestions for improved filter geometries are made, depending on the considered filtration process. Further, simplified models for the prediction of the effective thermal conductivity of open-cell foams in presence and absence of radiation are presented and validated using the detailed numerical predictions.

Abstract:
AbstractIn ultrasonic fatigue testing of steels one can observe rapid local heating due to crack initiation and propagation caused by non-metallic inclusions and in addition also an overall heating of the gauge length portion of samples which is attributed to dissipational effects. The computations performed in this study are based on a three-dimensional, fully-coupled linear thermoelastic continuum model, where dissipation is included by employing a volumetric heat source. In the numerical computation the temperature distribution evolution in the geometry of interest is the result of a combination of initial conditions, boundary conditions and the heat source contribution. The heat source function's geometry and intensity are deduced by comparing computed temperature profiles to data obtained experimentally using a thermo-camera. It turns out that the modeling approach, making extensive use of thermography data, yields computational results that are in agreement with the experimental heat evolution, and additionally the amount of heat generated is in agreement with results found in literature.

Abstract:
AbstractThis chapter is focused on the fatigue life and damage mechanisms of steel 42CrMo4 in the high cycle fatigue (HCF) and very high cycle fatigue (VHCF) regimes at temperatures up to 773 K. For this purpose, resonance fatigue testing was used at different test frequencies (90 Hz and 20 kHz). The influences of the manufacturing process (wrought or cast condition), as well as the core hardness (various heat treatment conditions), were investigated. Fractographic examinations of the fracture surfaces allowed the analysis of crack-initiating defects. Together with light microscopic observations of the defect distribution, the fatigue mechanisms of the steel 42CrMo4 were investigated at different temperatures (RT, 473 K and 773 K). A short crack model according to Chapetti applied to the present results was used to describe the change in the fatigue damage mechanisms operating at RT/473 K and 773 K, respectively. It is shown that high-temperature fatigue at 773 K was dominated by crack growth, whereas fatigue at RT and 473 K was dominated by crack initiation. These investigations complete the work presented in Chap. 24, in which the influence of nonmetallic inclusions on the ultrasonic fatigue behaviour of steel 42CrMo4 is being analysed at room temperature. The present results provide important insights into the crack-initiating defects and their distributions as they are relevant in typical industrial applications.

AbstractThe soil fabric can be expressed as a network model. Granular media voids connectivity and constriction size distribution may lead to movement of air, fluids, and solids in the soil, and therefore affect the chemical, physical and mechanical properties of soils. Understanding the soil voids areas and their interconnection might be helpful in understanding different phenomena such as transport in porous media, water retention, fluid flow in the soil, soil contamination, internal erosion, suffusion, and filtration. In addition, specifying the soil voids interconnectivity can help researchers and practical engineers to provide the best rehabilitation and remediation approaches. The pore network was investigated in the current study, assuming the soil particles to be similar to discrete spheres and particles with different shapes. Also, based on the modelling techniques, the profiles of pore connectivity and constriction size distribution were assessed.

Abstract:
The kidney plays a critical role in the elimination of many drugs from the body, hence consideration should be given to a patient’s renal function whenever any drug is prescribed. Much kidney disease is unrecognized, but the widespread reporting of estimated glomerular filtration rates (eGFR) has brought greater awareness of the prevalence of chronic kidney disease (CKD), thereby encouraging medical practitioners to take account of reduced renal function when prescribing. CKD is very often one of many coexisting comorbid conditions, especially in elderly patients, when particularly careful thought must be given to appropriate drug dosing and the possibility of drug interactions. A reduced GFR is the primary reason for reduced excretion of drugs in renal failure, but drug absorption, distribution, protein binding, metabolism, and pharmacodynamics may all be affected. Key general points—both filtration and secretion of drugs appear to fall in parallel and in proportion to the GFR. The clinical significance of a reduction in GFR and increased drug half-life depends on the relative importance of renal excretion and metabolism as a mode of elimination, and the therapeutic ratio of the drug. If nonrenal clearance accounts for elimination of more than 50% of a drug, then no adjustment needs be made to dose/frequency of administration. Dosages of drugs which are mainly excreted in active form by the kidney may need to be modified to avoid accumulation. Potentially toxic drugs should only be used in patients with renal failure if there is a specific indication for their use and if therapy can be monitored appropriately. If dose adjustment is required, then dose, dose interval, or both can be adjusted to achieve the desired therapeutic profile.

Abstract:
Abstract The complex reservoir architecture of the Malampaya carbonate buildup offshore Palawan, Philippines, was initially controlled by a rugged clastic basement morphology, which was overgrown by atoll structures during the Oligocene and early Miocene. Additional factors with major impact on reservoir quality are frequent and high-amplitude relative sea level fluctuations, ocean currents, and prevailing wind directions. Primary depositional reservoir-quality distribution has been overprinted by diagenetic events, primarily as a result of repeated platform-top exposure and submarine cementation. Inherent noise within the previous seismic data introduced by the complex overburden and buildup morphology has resulted in inconsistent seismic attribute distribution. Therefore, earlier reservoir modeling efforts used seismic horizon and volume interpretation only, coupled with the sequence- and cyclostratigraphic architecture and the concept of reservoir rock types for field development planning. Prior to gas-development drilling, another attempt was made to extract direct reservoir-quality information from the reprocessed three-dimensional (3-D) seismic data to validate the earlier deterministic reservoir models. Improved 3-D prestack depth migration based on a new velocity model has been the foundation of the quantitative seismic analysis for reservoir characterization, static modeling, reserves estimation, and optimized gas development and oil appraisal well targeting. High-porosity areas in the upper part of the reservoir were identified using top-reservoir reflection amplitudes. This provided the tool to minimize penetration of low-porosity, fractured zones prone to mud losses in the gas development wells. A series of acoustic-impedance inversions were applied to create reservoir porosity cubes from seismic and to target wells in good reservoir areas. Porosity cubes are also essential for a correct time-depth conversion of the static model, using a linear porosity-velocity relationship in clean carbonates, which was derived from well data. Several static model realizations were created using the porosity cubes from seismic as a backdrop combined with 3-D seismic facies analysis and a depositional model based on well data and analogs. The results of the five gasdevelopment wells have confirmed the modeled reservoir-quality distribution within the lagoonal part of the northern Malampaya accumulation. Early production performance following first gas in October 2001 is indicative of excellent lateral pressure communication in this area of the buildup, in accordance with earlier dynamic models. Porosity-height realizations created from the different seismic porosity cubes proved valuable to visualize uncertainty in reservoir-quality distribution within the Malampaya oil rim and formed the basis for targeting a horizontal appraisal well. The MA-10 horizontal oil-rim appraisal well drilled at the end of 2001 confirmed the forecasted facies distribution and reservoir properties as derived from the model. Based on the new quantitative seismic reservoir characterization, additional areas of potentially good reservoir quality have been identified in the southern Malampaya culmination and on the western flank of the northern culmination. Both areas were previously considered to contain low-porosity reservoir caused by pervasive early marine cementation.

Abstract:
Abstract An integrated data set containing detailed three-dimensional ground-penetrating radar surveys, outcrop mapping, and both in situand lab-based petrophysical measurements provides an unusually detailed foundation for simulating fluid flow through the three-dimensional permeability structure of a channel sandstone reservoir analog within a study volume 40 m x 20 m (130 ft x 60 ft) (in plan) and 15 m (45 ft) deep. Permeability (k)data (more than 1100 data points ranging from 0.5-300 md) are obtained from probe permeameter measurements made on core plugs collected from five vertical cliff-face transects and on slabbed drill-hole core from four, 14-m-deep (42-ft) holes drilled 10-20 m (30-60 ft) behind the outcrop. Analytical petrography and comparison of outcrop kvalues with those from drill-hole core show that weathering has caused a factor of 2 to 5 increase in cliff-face permeability with a significantly different univariate kdistribution from that of the behind-the-outcrop drill-hole core. The permeability differences are accounted for by “correcting” the weathered cliff-face values to mimic the distribution of kvalues obtained behind the outcrop using an inverse transformation method. The field-based kdata are integrated into two classes of three-dimensional, geostatistically generated, stochastic permeability models. One model type uses ground-penetrating radar data solely to define important bounding surfaces with sandstone permeability extrapolated directly from the kdata. The other model type uses the ground-penetrating radar data to explicitly constrain a sandstone permeability structure and to define the geometry, thickness, and distribution of shale/mud-stone units. A series of two-phase fluid-flow simulations within 15 m x 15 m (45 ft x 45 ft) (in plan) by 10.8 m (35 ft) deep model domains, using grid blocks 1 m 2(9 ft 2) (in plan) and 0.2 m (0.7 ft) thick, yield several conclusions. First, replacing the entire volume with a single kvalue computed with arithmetic, geometric, or harmonic mean of all kvalues in the volume yields a poor approximation of oil production computed using the original detailed, heterogeneous kstructure. Second, in most cases upscaling using a vertically averaged geometric mean (as opposed to using arithmetic or harmonic means) provides a reasonable match to the oil production computed using the original detailed, heterogeneous kstructure. Third, it is important to distinguish between fully continuous versus discontinuous shale unit geometries, and to be able to estimate angle of shale unit dip, when selecting methods for upscaling outcrop permeability values for use in reservoir simulators. Integrating three-dimensional ground-penetrating radar surveys with outcrop-based sedimentological and petrophysical data can provide the estimates of size, dip, continuity, and distribution of shale units needed at the scale of individual simulator grid blocks to help improve our approaches for deriving the upscaled kvalues used as input to production-scale reservoir simulators.

Abstract:
Abstract Drilling fluids’ rheological and filtration qualities have been discovered to be improved by graphene nanoplatelets (GNPs). Research has demonstrated that adding GNPs to water-based mud (WBM) can enhance its plastic viscosity (PV), yield point (YP), gel strength (GS), filtration loss (FL), and filter cake thickness (FCT). Their small particle size, excellent material dispersion, and thermal stability are the reasons behind the usage of GNPs in drilling fluid. Here, GNP from Kenaf stem was synthesized, and its surface was modified with nonionic surfactant triton-X100 to improve its dis

Abstract:
Abstract Drilling in permeable formations, especially depleted reservoirs, can particularly benefit from simultaneous wellbore shielding and strengthening functionalities of drilling mud compounds. The ability to generate simultaneous wellbore shielding and strengthening in reservoirs has potential to widen stable mud weight windows to drill such reservoirs without the need to switch from wellbore strengthening compound to wellbore shielding compound, and vice-versa. Wellbore shielding and strengthening experiments were conducted on three outcrop sandstones with three mud compounds. The wellbo

Abstract:
Abstract Measurement of rheological and filtration properties of drilling fluids require significant amount of preparation time and experimental work and many times analysis of such data is done twice a day. However, some of these parameters such as mud weight, marsh funnel viscosity, flow line temperature, and solid content were measured much more frequently, typically every 15-30 minutes. In this study, we will cover Artificial Neural Networks (ANN) and Machine learning models (Support Vector Machine (SVM), Extreme gradient boosting (XGB), and Random Forest (RF)) to predict the KCl polymer m

Abstract:
Mud erosion in the subsea stratified sand-mud beds is a concern for production of methane gas from methane hydrate. It is expected that eroded mud may lead to well blockage. The goal of our work is to model of mud erosion that damages gas production. To approach this, we have developed a numerical simulation code and mud erosion is investigated to estimate model parameters. The water velocity in pore space is simulated by the Lattice Boltzmann Method (LBM). The paper shows the procedure to obtain erosion rate from distribution of shear stress on the mud surface.

Abstract:
In south-central Ontario, tunnel channels are primary targets for groundwater exploration due to their potential to contain confined, water-bearing, coarse-grained sediment fills. Despite extensive hydrogeologic and geologic exploration within these features, a comprehensive depositional model that illustrates the spatial distribution of coarse- and fine- grained sediment in tunnel-channel complexes is absent. Work in the Zephr area, north of ORM, presents new subsurface data to improve understanding of this geologic setting and to add to geologic models of these channel systems. Findings resu
