Seismic firm in London listing

■ Newly-formed IG Seismic Services is the latest Russian company to seek a London float, after yesterday announcing its intention to list its global depository receipts on the main market. IGSS, which provides seismic services to Russian oil and gas companies, believes it is well-placed to capitalise on strong growth in high-technology seismic services. The seismic market in Russia is expected to be worth around $1.4bn this year.
