Abstract

"TESTES APERFEIçOADOS DE PV DE FUNDO DE FURO PARA PRESSãO DE PONTO DE BOLHA". A presente invenção refere-se a um método de determinação objetivo de pressão de ponto de bolha que permite novas aplicações de resultados de teste de PV (Pressão Volume) de furo de poço tal como a medição no local da pressão do ponto de bolha para uso como um parâmetro de controle de qualidade para amostragem. A presente invenção proporciona um método e aparelho para ajustar pontos de dadoss para uma curva e para suavizar estes pontos através de um intervalo de N pontos. O derivado da curva é determinado para obter a aceleração de pico. A aceleração de pico representa a pressão do ponto de bolha. Esta pressão de ponto de bolha é verificada por comparação com alterações na compressibilidade do fluido e pela observação visual de uma histórico de gráfico de pressão volume.
