Fluid trap and baffle system

Abstract

Aspects of the subject technology relate to apparatus and methods for monitoring constituent components of underground fluids. A perforation device of the present disclosure may be physically attached to a casing, the casing may be placed in a wellbore, and an explosion may be initiated that results in establishing fluid communication between subterranean strata of a wellbore and sensors of a sensing apparatus. The perforation device may include a baffle that protects both explosive charges used to generate the explosion and a tube that couples subterranean fluid to the sensors. The baffle may protect the tube from physical damage and from being clogged by debris from the explosion. The baffle may also protect the explosive charges by collecting liquid that otherwise might wet the explosive charges. Data collected by the sensors may be evaluated before, during, and after the performance of a wellbore operation (e.g., a carbon sequestration operation).
