Palavras-Chave: Injecao de vapor, Conducao calor, Reservatorios oleo pesado Abstract - Estimation of the temperature field around a wellbore is an important problem in petroleum engineering. Heat transferred between borehole and formation during thermal recovery techniques, inducing stresses that may affect structural stability. Temperature well usually evaluated by numerical techniques such as finite difference method or inversion Laplace transform, assuming constant at wall. The proposed...
The unsaturated hydraulic properties provide important theoretical and practical information about fluid flow in soils rocks for a range of soil, environmental engineering applications. In this study we used the evaporation (HYPROP) chilled-mirror dew point (WP4C) methods to estimate water retention conductivity curves an Indiana Limestone carbonate rock sample. obtained data were analyzed terms unimodal bimodal VG (van Genuchten, 1980) PDI (Peters et al., 2015) type functions. Bimodal...
Neste estudo é realizada uma investigação, via modelagem computacional, das influências remotas que as anomalias positivas da temperatura superfície do mar (TSM) na região Confluência correntes Brasil e Malvinas (CBM), exercem no regime hidrometeológico regiões Sul Sudeste Brasil. Essa marcada por intensa frente oceânica formada pelo encontro águas transportadas pela Corrente (CB) (CM). investigação foi com a utilização modelo climático Community Atmosphere Model 2.01 (CAM 2.01), sendo...
Abstract Edge‐based data structures are used to improve computational efficiency of inexact Newton methods for solving finite element non‐linear solid mechanics problems on unstructured meshes. employed store the stiffness matrix coefficients and compute sparse matrix–vector products needed in inner iterative driver method. Numerical experiments three‐dimensional plasticity have shown that memory computer time reduced, respectively, by factors 4 6, compared with solutions using...
With the increased complexity of low-end devices in Internet Things (IoT), mainly due to connectivity and interoperability requirements, development configuration embedded operating systems (OSes) for such is not straight forward. The communication requirements usually mitigated by OS, e.g., Contiki-OS, as it already incorporates an IoT-compliant network stack. Yet, stack requires major knowledge on code structure, leading additional time, particularly when comprises several wireless nodes...
Abstract The closed-loop field development (CLFD) under geological uncertainties is a general methodology that aims to optimize an objective function by successively adjust the plan (DP) of oil as new information made available drilling and production wells. In this work, we propose CLFD procedure demonstrate its feasibility in UNISIM-I benchmark case, based on Namorado Field Brazilian Campos Basin. cyclically uses steps history matching, selection representative models optimization DP...
Nuclear magnetic resonance (NMR) is a recognized petrophysical tool in the oil and gas industry to characterize reservoir rocks fluids. In this study, pore system of coquinas from single bed quarry Morro do Chaves Formation was evaluated. These sedimentary have been considered as potential analogous some Brazilian pre-salt rocks. The objective work porous terms total porosity size distribution using low-field NMR. Conversion T2 relaxation times radii performed literature cut-offs were...
High porosity and low permeability limestone has presented pore collapse. As fluid is withdrawn from these reservoirs, the effective stresses acting on rock increase. If strength of overcome, collapse may occur, leading to irreversible compaction porous media with reduction. It impacts withdrawal. Most reservoirs have been discovered in weak formations, which are susceptible this phenomenon. This work presents a study mechanical behaviour reservoir located Campos Basin, offshore Brazil. An...
