3-D Seismic Survey Design As an Optimization Problem (SEG 1998, OnePetro)
https://onepetro.org/SEGAM/proceedings/SEG98/SEG98/SEG-1998-0117/86512 (OnePetro)
Treats land 3-D survey design as a constrained optimization: choose geometry/parameters to hit target fold, bin size, and far offset while balancing practical trade-offs (cost/operational limits vs. imaging goals). Frames “good design” as minimizing misfit to target attributes under real-world constraints.

https://doi.org/10.1190/1.1438430 (Crossref Chooser)
Frames 3-D (orthogonal) land survey design as an optimization: choose a small set of geometry parameters by minimizing a cost function defined as a weighted sum of deviations from user-specified geophysical target values (e.g., offsets, fold/coverage, sampling attributes). It provides a practical way to compute “best compromise” designs from target criteria.

DMO Amplitude (SEG 1995, OnePetro)
https://admin.onepetro.org/SEGAM/proceedings/SEG95/SEG95/SEG-1995-1437/85298 (admin.onepetro.org)
Proposes a DMO approach aimed at preserving relative amplitude variations already present after NMO, i.e., focusing on amplitude fidelity rather than only kinematics. The emphasis is on keeping amplitudes consistent through the DMO step so later interpretation/inversion isn’t biased by processing-induced scaling.
Sloping event DMO amplitude (EAGE / EarthDoc, DOI)
https://www.earthdoc.org/content/papers/10.3997/2214-4609.201408884 (earthdoc.org)
Discusses DMO’s role in both traveltime and amplitude correction, specifically for dipping/sloping events. The paper motivates amplitude-aware DMO so that dipping reflectors don’t suffer systematic amplitude distortion when preparing data for migration.

Minimum Phase Signal Shaping with the Double Least Squares Algorithm (EAGE / EarthDoc)
https://www.earthdoc.org/content/papers/10.3997/2214-4609-pdb.131.GEN1997_A027 (earthdoc.org)
Presents a “Double Least Squares” method to convert an arbitrary-phase wavelet (or an effective wavelet estimated from a seismic trace) into a minimum-phase / minimum-delay equivalent. It does this by computing a zero-delay least-squares (Wiener) spiking filter, then computing a second spiking filter from the first; increasing filter lengths improves the power-spectrum match. Applied to Vibroseis data as a preconditioning step before Wiener-Levinson deconvolution, it improves event resolution and continuity.
Geophysics and the Internet (2000, The Leading Edge)
https://pubs.geoscienceworld.org/seg/tle/article-abstract/19/8/877/59114/Geophysics-and-the-Internet
Reflects on how the emerging Internet transforms access to information and communication, comparing its impact to past technological shifts. He highlights its vast, growing resources and implies the geophysics community will increasingly rely on online tools and connectivity to share data, knowledge, and research.
