My career in the oil and gas industry started in 1975. Shortly thereafter, a theme that became wildly popular in conferences, workshops, and internal boardrooms was better integration of seismic with other oilfield disciplines. Initial progress was slow, but, if we fast-forward to today, we see that significant strides indeed have been made. A good representation of integration papers appeared this past year, so that is the theme we will use.
Advancement of the integration of seismic with other oilfield disciplines has been fueled by two factors. First, evolutionary advances in seismic technologies naturally led to more-powerful integration. A simple example is the progress made in bandwidth. In this regard, advances in seismic sources, field recording equipment, and data processing all benefited interpretation, inversion, and reservoir modeling. For example, in the 1980s, a commonly used vibrator sweep in land surveys was 12–48 Hz. Today, sweeps start as low as 2 Hz and often go up to more than 100 Hz. The benefits to resolution and derisking have been striking.
Second, several developments in seismic were motivated in direct response to the needs of interpreters and engineers. For instance, the appearance of creative, new, high-channel-count survey designs provided full-azimuth, densely sampled data that led to striking advances in imaging complex structures (especially in subsalt settings) and provided the wherewithal for characterizing natural fractures and stress in both conventional and unconventional plays. Indeed, this tighter integration of seismic with geomechanics energized the rise of the microseismic technique.
Six integration papers were selected. Three are presented here in summary format, and three are listed for additional reading. They come from all over the world, cover a range of reservoir lithologies, and deal with a suite of geologic settings. Let’s keep the progress moving.

Production Optimization in Waterfloods: A New Approach to Interwell-Connectivity Modeling
In the complete paper, the authors present a novel methodology to model interwell connectivity in mature waterfloods and achieve an improved reservoir-energy distribution and sweep pattern to maximize production performance by adjusting injection and production strategy on the well-control level.
Formation Evaluation: A Critical First Step
Emerging technologies have helped bring about multilateral, maximum-contact, and smart-completion wells, allowing reservoirs to be developed and produced much more efficiently and economically. In this, formation evaluation plays a critical role.
