Depth Conversion is a robust, but iterative process which can offer a good amount of uncertainty when it comes to working out what is below. If you’re using VelPAK or Kingdom IHS in order to determine your depth, then there is help with the form of Velit, a Depth Conversion Software plugin which is designed to offer vast libraries which can take into account most scenarios regarding depth conversion.
Velit is impressive indeed, and can offer a range of different scenarios regardless of the status of your potential asset. Whether it is marine or land based, and in a variety of different situations. Velit is also designed to be extremely user friendly and despite the fact that it’s a rather powerful tool with an expansive collection of libraries and methods, offers a far superior workflow which even straight out of the box is a major plus to running a vanilla version of Petrel or IHS Kingdom.
Using Velit can enable you to get a more accurate depth conversion, which permits the production of depth and thickness maps which depict subsurface layers – based on time domain seismic imaging. Robust and efficient, Velit allows for rapid scanning and determination of time migration velocity, the program itself running your data through repeated migrations in order to ascertain the most likely scenario, or by velocity continuation if you prefer. Time migration is considered best practise for seismic imaging in areas which mild lateral velocity variations.
Velit is a tool which is absolutely crucial for better depth conversions, and a much more simplified workflow for tasks such as hydrocarbon exploration which permits the volumetric evaluation of gas or oil. Furthermore, Velit allows depth conversion to be carried out as part of its interrogation of well data, with the option to allow seismic imaging to be carried out in addition, for extra peace of mind.
