“We will next trial our automated technique on recent, high-quality datasets that incorporate more three-dimensional details,” says Kalita. The resulting model is then tested alongside observed data to check that the surrounding rock structures match up and to ensure the model has not been “over-flooded.” Initial trials using a 1990s dataset from the Gulf of Mexico showed promise, with the new technique generating an accurate representation of local salt bodies. “Our technique takes the initial data from this top layer and ‘smears’ it across the most likely area that the salt body encompasses. “For the topmost layer of salt, we get a good enough signal to determine where the salt body begins, but then the soundwave energy rapidly disperses,” says Kalita.

Kalita and the team developed a two-part optimization process to refine FWI for salt body imaging. However, the lack of low frequencies in soundwave data from salt bodies means that a traditional FWI fails.

We’ve developed a robust computational method for interpreting seismic data from salt bodies quickly and more accurately.”Įxisting models use a technique called full waveform inversion (FWI) to minimize the disparity between observed and modeled data. “This is a time-consuming and expensive process that carries the risk of human error. “Data from salt zones are presently analyzed by highly trained experts rather than modeled by a computer,” explains Mahesh Kalita, a KAUST Ph.D. He discovered a fascinating way to see sound waves by using a violin bow to vibrate a metal plate covered with a fine powder, such as salt. 100 of our profits go to charities focusing on social justice, the environment, disaster relief, music education, and mental health. Furthermore, the salt’s crystal structure means that soundwaves are reflected at random, and there are no useable low frequencies retained in the seismic data. Ernst Chladni was a scientist who studied acoustics in the 1800’s. Soundwaves Art Foundation We are a philanthropic foundation that makes original pieces of art by capturing the digital heartbeat of some of the world's most iconic music. This causes stress-related complexities between the salt and the surrounding rock layers. Salt is a low-density, buoyant substance, meaning that salt bodies gradually rise through the Earth’s crust over time. However, in some regions, such as the Gulf of Mexico, the subsurface is peppered with salt bodies, which are huge accumulations of salt formed millions of years ago deep inside the Earth.
