1. Estudo sobre injeção de agua acima da pressão de propagação de fratura / Study of water injection with fracture propagation pressure
Produced water re-injection is a valuable method of water disposal and pressure and energy support. A common water re-injection problem is the injectivity loss, which affects negatively the process and restrains optimal water injection rates. The injectivity loss can be minimized by water injection with fracture propagation pressure (IFPP), which aims to res

2. Modelagem de injeção de agua acima da pressão de fratura do reservatorio atraves de poço horizontal virtual / Modeling water injection above reservoir formation parting pressure through a virtual horizontal well
Water injection has been the most used method to improve oil recovery. The main problem of this method, related directly with operational efficiency, is the injectivity loss which is the loss of capacity to maintain water injection rates due to formation damage. Different models have been proposed to minimize the injectivity loss effects due to its high econ

3. VERIFICAÇÃO DE MODELOS ANALÍTICOS PARA A PERDA DE INJETIVIDADE DE ROCHAS / ANALYTICAL STUDY OF THE INJECTIVITY LOSS OF ROCKS
This work deals with the impairment of rocks subjected to the injection of water with solid particles in suspension. The effect of the permeability reduction and consequent loss in rock injectivity is analyzed by the interpretation of core flow tests, previously reported, and simulated by using a computational program developed for this research. The program

4. NUMERICAL STUDY OF LOSS OF INJECTIVITY IN ROCK / ESTUDO NUMÉRICO DE DECLÍNIO DE INJETIVIDADE EM ROCHA
Esta dissertação apresenta um estudo numérico, utilizando o método dos elementos finitos, para simular o entupimento de rochas provocado pela injeção de água contendo partículas sólidas. Dentre os diferentes parâmetros que afetam o declínio de injetividade, quatro foram analisados, considerando-se a situação de fluxo unidimensional: fator de dan
