At this year’s URTeC exposition in Denver, Colorado, we enjoyed meeting some familiar faces, as well as making new friends to discuss the latest advancements in our Depth Conversion and Seismic Inversion products.
We were located on the IHS Markit Booth 523 where we presented several talks and demonstrations covering the use of our toolset in Unconventional resource plays.
It has historically been the case that most on-shore U.S. basins have required little use of geophysical approaches, due to the ‘pancake-flat’ geology and high density of drilling data. However, due to the rapid decline curves in production from these wells, over the past decade or so, a lot of the ‘easy’ targets have been reached. Looking to the future, more geophysical analysis is going to be required to more accurately map and decipher true depth, especially with areas of increasing geological complexity, that have yet to have been explored unconventionally.
Rather interestingly, a common misperception is that traditional depth conversion techniques are not required on flatter structures, where in practice, flatter structures are highly sensitive to small variations in the velocity model; potentially a few feet or metres per second variation being the difference between a prospect being economically viable, or not.
For example, the relevance of traditional approaches to determine highly accurate velocity models in the Permian Basin is evidenced in the several areas whereby the velocity of some of the limestone sequences are so fast that a 3ft/s variation relates to a 50ft difference in depth! With drilling targets being 15-30ft thick in places, the need for precision has never been more necessary.
Our discussion focused on the workflows that can we employ to help you achieve the results you require; achieving a highly robust velocity model, from sparse data, in complicated geological settings, and well as determining the Absolute and Relative Impedance signatures of your targets.
