Spectraseis completes survey for shell Egypt

SPECTRASEIS HAS COMPLETED a Low Frequency (LF) seismic survey for Shell Egypt NV in the North East Abu Gharadig (NEAG) Basin, Western Desert, Egypt.


The survey objective was to introduce LF technology in the Western Desert of Egypt. The project is the largest ever LF seismic synchronous survey, with 110 data points recorded over four days. The survey data is currently being processed with initial results expected in early February 2010.
The project took place with the logistical support of Ardiseis, a regional joint venture between CGGVeritas and TAQA in the Middle East region, and covered a 60 sq km area in one week using a team of 17 crew members.
It also saw the mobilisation of 120 recording stations - the largest equipment shipment for a single LF seismic survey by Spectraseis, and featured Spectraseis' recently launched field acquisition system, Field Office 2.0 and its innovative numerical technique Time Reverse Imaging (TRI).
TRI spatially localises the source of hydrocarbon microtremors, allowing operators to directly image hydrocarbon reservoirs at depth.
Spectraseis Director, Karim Lassel, said: “The completion of this survey represents a number of major milestones for Spectraseis – it is the first survey with Shell in the North African region, it marks our first collaboration through Ardiseis, and it is the largest synchronous survey we have ever completed.”
He continued: “The size and remoteness of exploration activities in North Africa, the region’s geological complexity, and the need to reduce exploration risk make this an ideal location for LF seismic surveys”.
Furthermore, the fact that we could complete the survey so quickly, with so few infrastructure resources and HSE risk and with such a light environmental footprint, is testament to the huge benefits LF seismic brings to oil & gas exploration.” Spectraseis' recently launched field acquisition system, Field Office 2.0 and its innovative numerical technique Time Reverse Imaging (TRI).
