How filter cake is formed
Weba cake formed during filtration is proportional to the amount of cake deposited at the filter medium provided cake porosity and filtration pressure are assumed constant. This principle, which infers that conventional theory is only valid when a cake is incompressible, is manifested in the now widely used general filtration equation. Web22 dec. 2024 · Filter cake properties such as permeability, porosity, toughness, thickness, structure, particle size distribution are the key elements that influence the fluid invasion into the drilled formations, and therefore, they affect the formation productivity (Ba geri et al., 2013a; Li and He, 2015 ).

Webfilter cake formation. It results in the delay of external cake formation if compared to particle penetration into the rock. The growth of internal cake formed by the fine particles inside the external cake after the transition time is not accounted for in the models for either drilling fluid invasion or water injectivity ( Pang and Sharma ... Web24 feb. 2024 · Drilling fluid and filtrates invasion often alter the near-wellbore flow properties during overbalanced drilling. The utilization of polymeric gels to prevent drilling fluid loss reduces the risk of formation damage caused by this alteration. In this study, the internal and external filter cake evolution by polyacrylamide (PAM) cross-linked with …
Web7 apr. 2024 · Figure 8 shows the slickness and texture of the mud cake formed during the API filter press test. Based on the physical investigation of the mud presented in Fig. 8 , it was observed that the mud cake formed by sodium alginate and Pure-bore demonstrates slickness and smooth texture, an important characteristic required in the wellbore. Webthat the sedimented particles are considered as a part of filter cake. Thus the mass of cake per unit filter area, W, was cal-culated as the sum of the amount of cake formed by filtra-tion, i.e. rSV/(1-S/S c), and the amount of sediment, rSv st/ (1-S/S c). Here, vs is the sedimentation velocity. If this would
