In order to avoid solid-liquid gravitational separation of particles in the drilling fluid and cuttings generated this process, oil industry has been developing fluids with shear-thinning thixotropic characteristics. case operational stops intense sedimentation these can damage equipment used well. context, study simulated an stop obtain information about stability solids a paraffin-based suspension time-dependent behavior, which already current processes. A long-term test using gamma-ray...
Oil wells drilling processes are a crucial step in petroleum exploration and fluids an important player this operation. Both solid–liquid sedimentation stability appropriate rheological characteristics significant desirable aspects for fluid. In context, study aimed at analyzing the of olefin fluids, differentiated by calcium carbonate additive, related to solid–fluid interaction behavior. Rheology, gravitational, batch experimental tests were performed as both time function position. A low...
Abstract After the cementing of an oil well, part drilling fluid is confined in annulus between cement and isolation tool (pack off). During production phase a will be exposed to temperature gradient due circulation reservoir through screen. This increase causes pressure evolution that can damage isolation. Among several possibilities for APB mitigation, strategy communicating with formation often considered. In this case, when reaches fracture, would drained from thus, released. However,...
Drilling fluids behave as shear-thinning and thixotropic present cuttings solid additives. Understanding the sedimentation of these elements is important to avoid possible problems in drilling. In that matter, this paper analyzed solids polymeric solutions assessed influence particle size process. Particle was monitored by gamma-ray attenuation technique. Equations pressure on were also determined. Different-sized particles deformed fluid settled with different velocities. Therefore, work...
Drilling fluids are used in the process of drilling wellbores. They formulated by a combination solubles and suspended solids. During drilling, cuttings rock formation may get mix. Some them too small light to be removed from fluids. called low-gravity solids (LGS). In no situations, both settle due gravity. This project aimed characterize physical rheological properties synthetic-based monitor distribution concentration batch gravity settling experiments. The interplay solid content mud...
O estudo da sedimentação de partículas em fluidos não-newtonianos é extrema importância para a indústria petrolífera, visto que se assemelha ao estágio parada técnica do processo perfuração. Os utilizados nesse apresentam comportamento reológico semelhante aos não newtonianos pseudoplásticos. Uma característica desejável manter suspensão os cascalhos produzidos na perfuração poços petróleo quando o fluxo fluido está cessado. Nesse contexto, esse trabalho objetivou avaliar concentração...
A sedimentação em fluidos não newtonianos tem sido alvo de estudo processos exploração petróleo, visto que, quando os poços estão operação, ocorre a separação gravitacional sólido-líquido que pode aumentar probabilidade dos desgastes equipamentos bem como fratura das formações devido às altas pressões bombeio e hidrostática. Neste contexto, este projeto objetivo avaliar batelada partículas meio aquoso polimérico newtoniano utilizando Técnica Atenuação Raios Gama (TARG). Esta técnica permite...
