Sierra Leone – Released 2D Seismic Data

PDSL – Petroleum Directorate of Sierra LeoneMulti-Client Technical Data, Report and Products

The PDSL 2D seismic data consists of surveys of various vintages, including the SL 2001 survey acquired by TGS in 2001 andthe SLI 2013 (Sierra Leone Infill) survey acquired by TGS in 2013. Together the surveys equate to 16,271 line kms of seismicdata, 10,484 line kms of gravity and 8,589 line kms of magnetic data. The surveys provide substantial coverage of the offshoreSierra Leone acreage. A suite of 1980’s legacy shallow water 2D data, acquired on behalf of Mobil and Amoco, is alsoavailable.

The released 2D surveys are available to license from Getech on behalf of the PDSL and include the following surveys:

Survey Name 2D or 3D Data Volume (line km or sq km)

SL 2001 2D (2001) 2D 5,784 line km

SLI 2013 2D (2013) 2D 10,487 line km

80MSL (1980) 2D Circa 2,506 line km

81MSL (1981) 2D Circa 3,337 line km

ASL83 (1983) 2D Circa 127 line km

ASL84 (1984) 2D Circa 2,429 line km

ASL85 (1985) 2D Circa 395 line km

UC 2D Circa 1,037 line km
