摘要： A method of controlling fluid loss from a wellbore comprises the steps of: installing a completion string including a well screen and a fluid loss control device in the wellbore; then installing a production string in the wellbore; then engaging the production string with the completion string; and then operating the fluid loss control device by varying pressure in a fluid passage. A well system comprises a completion string including a fluid loss control device, a packer and a well screen, the packer being positioned between the fluid loss control device and the screen; and a production string including another packer and engaged with the completion string, the fluid loss control device being positioned longitudinally between the packers, and the fluid loss control device being operable in response to variation of pressure in a fluid passage.
