Abstract
Empleo de ésteres seleccionados, fluibles y bombeables en el intervalo de temperatura desde 0 hasta5 C, de alcoholes monofuncionales con 2 a 12 átomos de carbono y ácidos monocarboxílicos olefínicamente sencillay/o multiplemente insaturados con 16 a 24 átomos de carbono como fase de aceite o al menos como porcentaje mayoritario de la fase de aceite de lodos para el barrido de perforaciones, que son adecuados para la explotación fuera-costa compatible con el medio ambiente de yacimientos de petróleo o bien de gas natural y que contienen en una fase de aceite cerrada una fase acuosa dispersa así como emulsionantes, agentes de carga, aditivos de fluid-loss, formadores de viscosidad y, si se desea, otros aditivos habituales conjuntamente con una reserva alcalina con la condición de que se renuncia al empleo concomitante de bases fuertemente hidrófilos, como hidróxido alcalino y/o dietanolamina, y un aditivo de cal, dado el caso, presente se limita a una cantidad máxima de aproximadamente 5,70 kg/m 3 de lodo aceitoso.
