Historically it was thought that productive, reliable OHGP completions could not be delivered when using well bore strengthening mud systems due to the inability to effectively produce back filter cakes with large solids through the gravel pack and the ability to condition the mud system...

The flux surveillance model for OH-SAS assumes the filter cake from drilling operations does not cleanup uniformly during fluids unloading and production...

... Abstract Barite is one of the most common weighting materials used in drilling fluid for deep oil and gas wells. Consequently, the main source of solids building the filter cake is the weighting material used in drilling fluids ‘Barite particles’. Barite is insoluble in water and acids...

... and effectively decrease drilling fluid losses. Using these techniques to control lost circulation with bridging materials can be extremely difficult when drilling with non-aqueous, oil-based fluid. The reduced permeability of an oil-wet filter cake prevents carrier fluid leak-off and necessary solids...

... porosity, low permeability filter cake on the wellbore wall reducing or preventing losses to the formation and effectively widening the operating mud weight window. In Casing Drilling operations the casing is used to drill the well so the (pipe size/hole size) ratio will be larger than the ratio when...

... Abstract Fracture fluid damage caused by residual polymer gel in propped fractures results in low fracture conductivity and short effective fracture length, sometimes severely reducing the productivity of a hydraulically fractured well. The residual gels are concentrated in the filter cakes...

... Ottawa sand was performed with humidified nitrogen gas flow. Retained conductivity of 84 to 100% was obtained after wet-gas cleanup for temperatures ranging from 120 to 200°F under a 2,000-psi closure stress. All conductivity tests were performed between Ohio sandstone wafers with filter-cake buildup...

... Abstract Cleanup of drilling fluid filter cake in long horizontal and multilateral wells is a difficult task. Both mechanical and chemical means (acids, oxidizers, chelating agents, and enzymes) have been used in the field. However, these methods have serious limitations and can adversely...

Compliance also improves filter cake clean up by reducing mixing with failed sand. The effect of compliance has been investigated in two sets of experiments. The first...

... and heavy oil reservoirs. During the drilling process, the formation pore pressure is less than the drilling fluid's hydrostatic pressure. This can lead to some fluid loss before a filter cake is formed to prevent further mud losses. For unconsolidated formations, it is prefer to keep the filter cake...
