CGG and Ardiseis, subsidiary of Arabian Geophysical & Surveying Co. (Argas), have delivered 2,000 sq km of what the partners refer to as reservoir characterization-ready broadband seismic data on the West-Kalbsha survey on behalf of Apache Corp. in Egypt’s Western Desert.
The ultradense survey represents 72 million traces/sq km, which is 2-3 times denser that any survey acquired to date. In what the companies are calling a step-change, CGG deblended the data through an algorithm. The company’s CleanSweep and EmphaSeis acquired low-frequency-rich broadband data starting from 1.5 hz, which is free of the harmonic noise contamination that is known for hindering broadband high-productivity Vibroseis acquisition.
