... filter cake is established across the face of the formation, typically referred to as spurt loss, and a phase where all fluid loss is controlled by the leakoff through the filter cake. The major factors influencing spurt loss and filter-cake behavior are listed as follows: P. 821...

..., approximately 3912 cm 2 . Results from the HPS were compared to laboratory data, and significant differences in spurt-loss values were found. Surface texture was also found to be a significant factor in determining the extent of filter-cake formation. The paper provides insight into the differences between...

... contacts is presented, together with 3D fracture modelling of fractures with no downward containment. The paper highlights the importance of spurt losses in both frac designs and minifrac analyses, when fracturing high permeability reservoirs. A simple minifrac analysis, for use with complex fracture...
