abstract = "Abstract Full waveform inversion (FWI) is a model-based data-fitting technique that
has been widely used to estimate model parameters in Geophysics. In this work, we propose an
efficient computational approach to solve the \{FWI\} of crosswell seismic data. The
\{FWI\} problem is mathematically formulated as a partial differential equation
(PDE)-constrained optimization problem, which is numerically solved using a gradient-based
optimization method. The efficiency and accuracy of \{FWI\} are mainly determined by the
three main components: forward modeling, gradient calculation and model update which usually
involves the gradient-based optimization algorithm. Given the large number of iterations needed by
FWI, an accurate gradient is critical for the success of FWI, as it will not only speed up the
convergence but also increase the accuracy of the solution. However computing the gradient still
remains a challenging task even after the adjoint \{PDE\} has been derived. Automatic
differentiation (AD) tools have been proved very effective in a variety of application areas
including Geoscience. In this work we investigated the feasibility of integrating TAPENADE, a
powerful \{AD\} tool into FWI, so that the \{FWI\} workflow is simplified to
allow us to focus on the forward modeling and the model updating. In this paper we choose the
limited-memory Broyden–Fletcher–Goldfarb–Shanno (L-BFGS) method due to
its robustness and fast convergence. Numerical experiments have been conducted to demonstrate the
effectiveness, efficiency and robustness of the new computational approach for FWI.",
