“…THF hydrate and natural gas hydrates both forms sII hydrate structures, also, thermal & mechanical properties of THF hydrates are similar to methane hydrates having sI structures [6,30,31]. Therefore, THF hydrates can be used as a replacement of methane hydrates [10,29,31,32]. All the induction time measurement experiments were repeated five times and the average value of all the five runs was taken as the final induction time and shown in Table 1.…”

“…Para Agwu et al, (2018) el hinchamiento de las arcillas es responsable de algunos problemas operacionales durante la perforación como: presencia de los puntos apretados durante los viajes corrida de revestidor, bajada de registros, y en muchos de los casos estos puntos apretados pueden generar una carga de cortes, adicional en el anular que podría dar problemas durante la perforación o la cementación del revestidor. La dispersión de las arcillas aumenta el riesgo de daño de formación, y modifica significativamente las propiedades más importantes del fluido de perforación (Fereidounpour y Vatani, 2015) como: densidad y reología, considerándose como una contaminación del fluido de perforación que merece tratamiento inmediato.…”

“…Sensitivity analysis of dissociation status of hydrate around wellbore during the drilling operation is scarce now. Fereidounpour and Vatani [16] developed the polyacrylate drilling fluid to prevent hydrate dissociation and wellbore instability caused by disturbance of drilling mud during drilling operation. The experimental results show that the designed drilling fluids can effectively reduce the possibility of hydrate dissociation in the near-wellbore region.…”
