Petrobras started 4D monitor acquisition over the Marimba field in the Campos Basin At the time writing this is considered as the largest seabed monitor survey acquired worldwide to date Abstract One of the proven technologies for reservoir monitoring is 4D timelapse seismic It allows tracking the fluid front for water gas and detecting pressure density changes Although 4D seismic monitoring is challenging in the Middle Eastern carbonate reservoirs dealing with nonrepeated acquisition geometries pose additional challengesThis paper will present how the 4D seismic Deep water OBC 4D

quality images in areas where conventional streamer methods are viewed as inadequate In the Campos Basin eight OBC surveys have been acquired over the past two years The complex infrastructure environment in the Campos Basin requires detailed presurvey planning to ensure that adequate coverage and 4D positioning HighDensity OBCA Step Change in Reservoir ImagingA BP Efficient interpretation of frequently repeated OBC 4D The 4D signal in the inline display also looks more continuous on the broadband data at the Shetland level and is comparable to the OBC data Overall at this stage we observe good continuity and improved resolution in the broadband data Improvement of the fine details and reduction in the 4D noise increases confidence in the 4D results Summary The Kinnoull field in the North Sea has both narrow azimuth towed streamer NATS and OBC surveys acquired preproduction When an OBN monitor was acquired this allowed us to directly compare the optimum OBNonOBC 4D to an OBNonstreamer or mixed acquisition 4D NRMS of the benchmark OBNonOBC result was 018 To understand the impact of the rich azimuth coverage of OBC data Deep water OBC 4D Acquisition SBGf Grane PRM From

answered the workflow is a 4D seismic has been widely used to monitor and manage reservoir development in the past few decades Nowadays seabed permanent reservoir monitoring with the OBCOBN technology has been commonly applied to provide lifeof Caspian Geo Abstract This paper describes 4D interpretation results in a very challenging Middle East carbonate contextIt consists of a 4D pilot OBCOBC over a giant field divided into two phases For Phase1 the monitor seismic survey has repeated the geometry of the base survey parallel shooting to get started in the best possible 4D conditions For Phase2

PRM vintage Towed Streamer 4D processing is to start soon the PRM vintage OBC 4D project has recently been finalised The 2001 and 2003 OBC surveys covering different parts of the field were merged and compared to the PRM0 dataset in an attempt to track 4D changes created by ten years of production The results of the 4D decimation study show that even where the 4D signal is large decimation quickly affects the spatial resolution and the ability to see subtle 4D effects A final element in our OBC design process is the potential to match our new acquisition to existing streamer data for 4D Deep Water Obc 4D Acquisition Earthdoc Summary The specifications of the permanent OBC LoFS array at Valhall were designed to produce timelapse images of the reservoir at 25km depth Advances in processing technology have been leveraged to reprocess the data from several legacy LoFS surveys in order to produce high resolution images of the overburden beyond the original specification of the array Inclusion of the downgoing The acquisition of seismic data is to generate seismic waves in the ocean by artificial means so as to collect seismic data accordingly OBC seismic exploration requires that the navigation process cannot be interrupted during the cable laying operation The whole laying process is a continuous process When there are obstacles on the laying Western Geophysicals new Commando

seismic acquisition vessels have been undergoing refittings and even rebuilding to increase their capabilities for taking on high tech multistreamer seismic In the Campos Basin eight OBC surveys have been acquired over the past two years The complex infrastructure environment in the Campos Basin requires detailed presurvey planning to ensure that adequate coverage and 4D positioning repeatability

not affected by oil platforms or tankers working in the oilfield which is a big problem for towed steamers ocean bottom acquisition can repositioned more easily than steamers or even continuously
