... of an acid fracture job requires accurate prediction of fractured well productivity. Productivity estimation demands knowledge of both the acid penetration length and conductivity distribution for the given reservoir. The literature includes several models developed to predict the conductivity of acid...

.... A fracture propagation model coupled with acid transport, reaction, and heat transfer was employed to determine the acid etched-width distribution and stimulated reservoir area. The outcome of the coupled model was the acid dissolution and conductivity distribution of a natural fracture network intersecting...

... the characteristics of fractures such as their aperture, density, distribution, conductivity, connectivity, etc, is key for reservoir engineering and production analysis. Well testing plays a key role in the the characterisation of fractured reservoirs, especially. New advances in the Pressure Transient Analysis...

.... Fracture networks are commonly multi-scale and properties including aperture (or conductivity), length, connectivity and distribution vary greatly within a reservoir. The heterogeneous nature of fractured reservoirs make them very difficult to characterise and develop. In addition, the location...

Numerical simulation confirmed that pressure dependent conductivity estimated from the step-by-step PTA...

... of the gases adsorbed on the surface of the organic pore walls are produced. This results in an increase in the pore volume available for subsequent CO 2 storage. However, the pore-pressure drop also results in an increased effective stress, which could lead to a reduction in fracture conductivity...

However, this conservative approach impaired proppant-pack conductivity and the effectiveness of the fracture half-length...

... Abstract Cross-linked hydraulic fracturing fluid gel can induce high damage in the fracture when left for a long time. Any residual gel not produced back reduces the conductivity of the fracture and the well productivity, leading to an extended flowback for a cleanup operation, which...

... Abstract Acid fracturing is one of the methods for well stimulation in carbonate formations. Compared to propped hydraulic fracturing, acid fracturing takes a simpler procedure, and therefore, usually with a lower cost. On the other hand, fracture conductivity is more difficult to maintain...
