Seismic Inversion is intended to convert seismic reflection data into quantitative rock properties which are descriptive of the reservoir which is subject to investigation. It has been established that the rock properties that can be ascertained from seismic inversion are directly representative of the reservoir itself, and it is for this reason that seismic inversion is performed.
Seismic Inversion shows far higher resolution and is not solely used to determine the characteristics of a reservoir. Instead, seismic inversion is something which is intended to compliment the depth conversion process in order to provide a far clearer picture of what is below. Of course, the costs associated with depth conversion and seismic inversion can be steep, but Uncertainty, and therefore, Risk, is something which can bankrupt both companies and entire governments.
How precious something is, is of course defined by the amount of it freely available. The word here is freely- extracting oil and gas is hardly a quick or a painless endeavour. Most oil fields have lives of 20+ years, and this is directly related to the amount of money it costs to drill into reservoirs, let alone excavate.
“Risk” and “Uncertainty” of course are terms that relate to the human cost of oil and gas extraction. Should an oil and gas reservoir be deemed unsafe to operate and to extract oil or gas from, there is no amount of money which would make it worthwhile.
Generally the consensus is that there is no such thing as being too careful, and seismic inversion is an extremely well received compliment to depth conversion which provides so much more data.
Seismic Inversion is used in a complementary fashion to Depth Conversion, and is often used to expand upon the clues that a depth conversion can provide. Seismic Inversion has those that advocate for it, and those that advocate against it, but seismic inversion, by its very nature, allows for time, money, and lives to be saved. Responsible excavation relies upon it.
