Joint stochastic constraint of a large data set from a salt dome (2016)
Journal Article
Roberts, A., Hobbs, R., Goldstein, M., Moorkamp, M., Jegen, M., & Heincke, B. (2016). Joint stochastic constraint of a large data set from a salt dome. Geophysics, 81(2), ID1-ID24. https://doi.org/10.1190/geo2015-0127.1

Understanding the uncertainty associated with large joint geophysical surveys, such as 3D seismic, gravity, and magnetotelluric (MT) studies, is a challenge, conceptually and practically. By demonstrating the use of emulators, we have adopted a Monte... Read More about Joint stochastic constraint of a large data set from a salt dome.

A Lambert W function solution for estimating sustainable injection rates for storage of CO2 in brine aquifers (2013)
Journal Article
Mathias, S., & Roberts, A. (2013). A Lambert W function solution for estimating sustainable injection rates for storage of CO2 in brine aquifers. International Journal of Greenhouse Gas Control, 17, 546-548. https://doi.org/10.1016/j.ijggc.2013.04.007

It is often of interest to estimate the maximum possible CO2 injection rate for a given maximum pressure buildup and injection duration scenario. Analytical solutions exist to estimate pressure buildup due to constant rate injection for a specified d...

Crustal constraint through complete model space screening for diverse geophysical datasets facilitated by emulation (2012)
Journal Article
Roberts, A., Hobbs, R., Goldstein, M., Moorkamp, M., Jegen, M., & Heincke, B. (2012). Crustal constraint through complete model space screening for diverse geophysical datasets facilitated by emulation. Tectonophysics, 572-573, 47-63. https://doi.org/10.1016/j.tecto.2012.03.006

Deep crustal constraint is often carried out using deterministic inverse methods, sometimes using seismic refraction, gravity and electromagnetic datasets in a complementary or “joint” scheme. With increasingly powerful parallel computer systems it i... Read More about Crustal constraint through complete model space screening for diverse geophysical datasets facilitated by emulation.

A framework for 3-D joint inversion of MT, gravity and seismic refraction data (2011)
Journal Article
Moorkamp, M., Heincke, B., Jegen, M., Roberts, A., & Hobbs, R. (2011). A framework for 3-D joint inversion of MT, gravity and seismic refraction data. Geophysical Journal International, 184(1), 477-493. https://doi.org/10.1111/j.1365-246x.2010.04856.x

We present a 3-D joint inversion framework for seismic, magnetotelluric (MT) and scalar and tensorial gravity data. Using large-scale optimization methods, parallel forward solvers and a flexible implementation in terms of model parametrization allow...

Massively parallel forward modeling of scalar and tensor gravimetry data. (2010)
Journal Article
Moorkamp, M., Jegen, M., Roberts, A., & Hobbs, R. (2010). Massively parallel forward modeling of scalar and tensor gravimetry data. Computers and Geosciences, 36(5), 680-686. https://doi.org/10.1016/j.cageo.2009.09.018

We present an approach to calculate scalar and tensor gravity utilizing the massively parallel architecture of consumer graphics cards. Our parametrization is based on rectilinear blocks with constant density within each blocks. This type of parametr...
