Seabed Geochemical Seep-Hunting & Heat Flow

TDI-Brooks conducts offshore seabed geochemical 'seep hunting' exploration (SGE) and heat flow programs for petroleum producers, and states that it and its partners have been involved for 40 years in designing and executing global seep hunting MBES programs. Projects start with an assessment of legacy seismic and geological data; deep seismic and multibeam surveys are then used to select piston coring locations based on surface expression of faults and other hydrocarbon migration conduits, followed by laboratory analysis and geochemical interpretation.

Since 1996 the company has collected over 50,000 deep water piston core sediment samples and heatflow stations in areas including the Caribbean, Gulf of Mexico, Mediterranean, North Atlantic, offshore Brazil and West Africa. Its SGE MBES global coverage is stated as 224,350 square kilometers, including a ~115,000 km2 TGS MSGBC West Africa program (2018) with the R/V Gyre.
