VelocityManager IIIMR II™ |

|
IMRII™ is the latest development in the IMR series. It is a well established process for the removal of depth artefacts caused in layer cake depth conversion by velocity anomalies in the overburden. These can be associated with fault shadows, salt diapirs, shallow sedimentary channels, and sea floor canyons. The IMRII™ process has been developed from successful research into the specific causes of the depth artefacts. This understanding has led to a highly effective, novel and robust process which will compute and remove the depth artefact. IMRII™ has the specific advantage over more commonly used techniques in that it does not filter the data whatsoever, 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 IMRII™.
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. |
