** **En un pozo de la Faja Petrolfera del Orinoco se est inyectando vapor de 90% de calidad a raznde 10.000 lb/h. El pozo est situado a 400 m de la planta y la lnea tiene un dimetro interno de 2,50 pulgadas y dimetro externo

de 2,75 pulgadas. La temperatura ambiente en el sitio del pozo es de 80F y generalmente no hay viento. Si la presin del vapor

a la salida de la planta es de 700 Ipca, calcular las prdidas de calor y la calidad del vapor en el cabezal del pozo.

** **Un pozo en Ta Juana, completado con un hoyo de 12 pulgadas de dimetro hasta unaprofundidad de 3.000 pies, tiene un revestidor de produccin de 8,52 pulgadas de dimetro interno y 9,60 pulgadas

de dimetro externo. La temperatura promedio en la superficie es de 80 F y el gradiente geotrmico de la zona es de

0,0120 F/pie. El pozo se somete a inyeccin de vapor a travs de una tubera de 3,25 pulgadas de dimetro interno y

3,50 de dimetro externo y recibe 20.000 lb/h de un vapor de 75 % de calidad en el cabezal y 600 F de temperatura.

Calcular las prdidas de calor y la calidad del vapor en el fondo del pozo, al cabo de 20 das de iniciada la inyeccin.
