Abstract

Procedimiento y aparato de sondeo desde una estructura de sondeo flotante en el mar de un pozo submarino, procedimiento caracterizado porque comprende las fases de conectar un tubo ascendente entre la nave de sondeo flotante y el pozo; perforar el pozo mediante operaciones realizadas a través del tubo ascendente; introducir una primera cadena de tubería de revestimiento a través del tubo ascendente e instalaría en el pozo; introducir un elemento postizo de encamisado en el tubo ascendente para reducir de un modo eficaz el volumen de espacio en el mismo; y continuar las operaciones de sondeo a través del elemento postizo de encamisado y la primera cadena de tubería de revestimiento.
