Method and system of determining parameters associated with a hydrocarbon bearing formation beneath a sea bed

摘要

Determining parameters associated with a hydrocarbon bearing formation beneath a sea bed. At least some of the illustrative embodiments are methods including: obtaining data gathered regarding a plurality of distinct readings by sensors, the readings responsive to a source of electrical energy towed in water above the hydrocarbon bearing formation, the sensors sense an electrical parameter associated with the source; combining a first datum associated with a first path of travel of the source with a second datum associated with a second path of travel of the source, the second path of travel distinct from the first path of travel, and the combining creates a first combined datum; and determining the parameter associated with the hydrocarbon bearing formation by evaluating the first combined datum.

1. A method comprising:
towing a sensor streamer along a first path of travel of a source, the sensor streamer comprising a plurality of electric field sensors polarized along the first path of travel, and the first path of travel above a hydrocarbon bearing formation; sensing by the electric field sensors polarized along the first path of travel, the sensing along the first path of travel creates a first datum; towing the sensor streamer along a second path of travel of the source, the second path of travel different than the first path of travel, and the electric field sensors of the sensor streamer polarized along the second path of travel, the second path of travel above the hydrocarbon bearing formation; sensing by the electric field sensors polarized along the second path of travel, the sensing along the second path of travel creates a second datum; combining the first datum associated with the first path of travel of the source with the second datum associated with the second path of travel of the source, the combining creates a first combined datum, and the first combined datum has a higher signal-to-noise ratio than the first datum or second datum; and determining a parameter associated with the hydrocarbon bearing formation by evaluating the first combined datum.
