Drilling at the Peró and Ingá prospects in block BM-C-40 and the Santa Helena prospect in BM-C-31 has turned up hits for Brazilian relative newcomer OGX. The operator has been focusing on shallow water opportunities (OE April) and has exploratory…
Andrew McBarnet suggests that the major marine seismic players are favourites to win in a crowded market.You would never realise it from the current crop of financial results and muted forward-looking statements from CEOs of marine seismic vessel operators…
A new world benchmark for hydraulic skidding was established this June in Geoje-Si, South Korea, with the loadout of the 19,400t deck for an Arctic class semisubmersible destined eventually to serve on Russia’s Shtokman gas field. David Morgan reports…
Conventional solids control methods are inadequate to manage low-gravity solids smaller than 8-10 microns. M-I Swaco’s Rich Cook discusses a new solution, recently successfully employed in West Africa, that helps manage these solids while keeping excess rig space to a minimum…
