NasserFeb 24, 2021 Investigation of Filter Cake Evolution in Carbonate Formation Using Polymer-Based Drilling Fluid Musaab I. Magzoub, Saeed Salehi, Ibnelwaleed A. Hussein, and Mustafa S. NasserThe filter cake is a very thin layer of solid particles deposited from the drilling fluid onto the surface of the drilled formation. This is essential during the drilling process as it reduces fluid filtrate invasion, contributing for the wells integrity. When the drilling processes are over, this formation must be removed efficiently to allow for the primary cement jobs to be conducted ...Jan 01, 2004 The filter cake obtained by this method was homogenized and liquefied acquired the fluidity, but the filtrate was contaminated by the dispersing agent. In the second method, two-stage filtration was carried out. In the first stage, a pre-layer of cake was formed using the calcium carbonate suspension without the dispersing agent.Oct 24, 2019 Various concentrations of calcium carbonate nanoparticle 0.0250.5 wt was added to water-based drilling fluid. Fluid loss volume, filter cake thickness and its surface morphology, and rheological properties of both base fluid and fluid containing calcium carbonate nanoparticles was measured and compared.

The SCal series replaced barite with calcium carbonate and the Sglass series used glass particles. The size and circularity of the barite, calcium carbonate and glass particles are summarised in Table 3. Mixing was achieved using a Silverson mixer at 6000 rpm for 35 minutes.The process of well cleanup involves the removal of an impermeable layer of filter cake from the face of the formation. The inefficient removal of the filter cake imposes difficulty on fracturing operations. Filter cakes impermeable features increase the required pressure to fracture the formation. In this study, a novel method is introduced to reduce the required breakdown pressure to ...Rapid dissolution of the calcium carbonate in the filter cake causes the breaker fluid to leak-off into the formation without treating the entire filter cake. Production of Filter Cakes. Filter cakes were produced in the laboratory to provide an experimental substitute for the filter cakes produced in a wellbore.
