Trillion Energy International Inc (CSE:TCF, OTCQB:TCFF) announced it has kicked off its 3D seismic reprocessing project for the SASB natural gas field in the Black Sea.
The Canadian oil and gas producer is hoping to create a superior model of the field’s complex geology by reprocessing with advanced pre-stack depth migration (PSDM) and incorporating time depth data from newer wells.
Trillion told investors that there have been “vast improvements” in seismic data processing algorithms since 2004, when the last 3D seismic data was shot by WesternGeco.

The existing 3D seismic data covers 223 square kilometres and includes the SASB block.
Trillion outlined the uses of the new PSDM seismic velocity model, including a more detailed and accurate mapping of individual gas reservoir units and better imaging of the gas trapping faults and superior structural maps.
Other uses include identifying and defining stratigraphic exploration gas prospects that have never been drilled, and mapping the deeper Cretaceous Akveren Formation (CAF), which has never been explored, but which contains tantalizing deeper anomalies based on the old PSTM model.
The company noted that there are many oil and gas seeps originating and contained within the Cretaceous sediments onshore proximate to SASB.
“Reprocessing the 3D seismic data using modern cutting-edge technology will increase our understanding of the gas potential at SASB and is the first step to making significant new discoveries,” Trillion CEO Arthur Halleran said in a statement.
“The cost of reprocessing is infinitesimal compared a new 3D shoot of this size. The reprocessing will allow mapping of extensions to existing structurally trapped gas pools, discover new gas pools and improve resolution of the stratigraphic exploration prospects. I am excited about what we will also see in the deeper Cretaceous age formations, where onshore oil and gas seeps have been found 20 to 30 kilometres from SASB.”
The data reprocessing is scheduled to commence early March 2023 and should take five to six months to complete.
