Abstract

The Raudhatain and Sabiriyah fields are situated in north Kuwait. In the Raudhatain Field, the Jurassic<br>reservoirs, Najmah-Sargelu and Marrat ,have two distinct northern and southern culminations,<br>separated by an intervening fault boundary; while in the Sabiriyah field the reservoirs are divided into<br>up thrown and down thrown sides along a NNE-SSW fault. In both the fields, the faults and associated<br>fracture networks have a significant impact on production.<br>In 2009, Kuwait Oil Company (KOC) acquired two massive 3DVSP survey in the Raudhatain and<br>Sabiriyah fields. The primary objective of the surveys were to improve the structural definition of the<br>Jurassic reservoirs, especially the Marrat reservoir and also to test the feasibility of characterizing the<br>fractured reservoirs using anisotropy information. The surveys consisted of 100-level multi-component<br>tool, combined with around 10,000 source points covering an area of around 64 square kilometers.<br>This is probably one of the largest onshore surveys in the region.<br>The high resolution and better signal to noise ratio in the VSP data, is expected to provide improved<br>structural definition in the vicinity of the well. This information will be utilized in locating future<br>appraisal wells. In order to reduce the survey time, a test was also conducted on four 2D lines of 6km<br>length, using four fleets of two vibrators, utilizing the High Fidelity Vibratory Seismic (HFVS) technique.<br>While the processing is ongoing, the results of the test are expected to produce data quality which will<br>be equivalent or better than conventional methods.<br>Based on the outcome of these surveys, future 3DVSP’s maybe acquired to help in developing the fields.
