A new model for predicting fluid loss in fracture-porosity reservoir

Drilling fluid loss always occurs in fracture-porosity reservoirs and it causes severe problems. To reduce prevent lost circulation, is important to get know the cause characteristic of drilling loss. According approach reservoir simulation well test analysis, a new model for presented. Multi fractures formation seepage between fracture rock matrix have been considered model. The governing equations are derived based on principle conservation mass. solved numerically using Newton-Raphson iterative method. obtained results indicate that leak-off has great influence total leakage volume. It necessary consider impact leak-off. In addition, properties, such as stiffness, porosity, permeability, operation factors, pressure difference wellbore formation, also analysed detail paper which could help better understand factors during operation.
