In our last post I showed our first ever depth migration of synthetic data over a simple syncline. Although the main reflector was correctly positioned the artefacts from both the line ends and the tails of the "bow tie" were distracting from the result. The swing artefact coming in from the line ends is quite obviously due to the truncation of the event and the resulting unbalanced migration operator. The common solution to this problem is to apply some sort of a spatial taper to the input data so that the closer you get to the end of the line…

At HSS we are quite comfortable with our status as an emerging seismic processing service provider. Part of the territory therefore is that most of our work to date has taken place in the time domain whilst leaving the depth processing work to our more established competitors. This is something that is about to change! Several enquires at the recent AEGC 2019 made us realise that there was an opportunity to provide some depth migration services if we add the requisite algorithms to our toolbox. Depth imaging has always been on our radar so there was a tentative plan already…

Seismic processing invariably involves the application of a sequence of algorithms to large quantities of digital seismic data. This sequence is often referred to as the "flow". Although each project tends to follow a familiar flow we're dealing with real world data here so modifications are required to deal with irregularities in the data (and metadata). For this reason seismic processing packages are more like high level programming languages where the flow is constructed by the user selecting appropriate modules and parameters to achieve the desired result. Flows in most seismic packages consist of a single pathway (a sequence of…

Welcome to our blog! We will use the blog to post software development news, ideas, interesting problems and solutions any other news that is relevant to our progress. Seismic imaging is challenging, rewarding and addictive. If you feel the same way please keep tuning in and get involved by leaving comments and letting us know what you would like to hear more (or less!) about. Enjoy!
