MÉTODOS PARA MONITORAR UMA FORMAÇÃO DE SUB-SUPERFÍCIE ABAIXO DE UM LEITO MARINHO E PARA PRODUZIR HIDROCARBONETOS A PARTIR DE UMA FORMAÇÃO DE SUB-SUPERFÍCIE ABAIXO DE UM LEITO MARINHO.

摘要

A method of detecting a lateral boundary of a compacting or expanding region in a subsurface formation, which method comprises determining non-vertical deformation of the earth' s surface above the subsurface formation over a period of time; identifying at least on contraction area and at least one adjacent dilatation area of the earth' s surface from the non-vertical deformation over the period of time; and using the contraction area and the adjacent dilatation area as an indication of a lateral boundary of the compacting or expanding region; and a method for producing hydrocarbons.
