Abstract The TOT-3P concept was developed to optimize the construction of post-salt wells, including drilling three sections and installing completion assembly in a single trip. This work presents technical fluid solutions enable this scenario, with extensive application Marlim Revitalization project, considering challenges associated presence an section shales followed by sandstone reservoir, as well specificities producing injecting wells. proposed solution aimed at enabling wells fields...
Abstract Fluid losses are still today one of the most challenging problems in well construction. The scenarios faced by operators during development and exploratory campaigns deep water pre-salt area characterized natural fractures, vugs caves. Therefore, related to loss circulation critical, increasing non-productive time consequently, construction costs. Additionally, several situations, conventional drilling limitations prevent reaching target. present study proposes application a...
Abstract The drilling of the evaporitic section using water-based mud (WBM) was always a challenge: even though there are already some wells drilled with saturated aqueous fluid, their use still divides opinions within technical-academic community oil industry. Basically, two currents: one that believes salt WBM causes an enlargement so great it becomes impracticable to cement casing and, consequently, obtain leak off test (LOT) or formation integrity (FIT) sufficient for next phase. other...
Abstract The reduction of the number sections in construction an offshore well is a major driver for cost reduction. In order to achieve this goal, must be longer, resulting additional challenges. A critical aspect related second section (no fluid return surface) reaching high inclinations and longer extensions. Such are drilled with fluids no carrying capacity, 1500 m as 65 degrees, expressive cuttings accumulation wellbore annulus. scope article present novel hydraulics design procedure...
