The IMR™ Plus process is now a well established process for the removal of depth artefacts caused in layer cake depth conversion by velocity anomalies in the overburden. The IMR™ Plus process has been developed from successful research into the specific causes of the depth artefacts. This understanding has led to a highly effective and novel robust process which will compute and remove the depth artefact. IMR™ Plus has the specific advantage over earlier techniques in that it does not filter the data, and as a consequence, it will reveal the true structure, and the ‘hidden detail’ in the faulting, as illustrated below. The maps below include a depth artefact. Move the mouse pointer over each to show them with the artefacts removed using IMR™ plus.
Below is a map of the extracted artefact.
Depth artefacts are found in different basins all over the world. In the UK, they are characterised by problems in the Southern North Sea and Atlantic margins.
