Occidental Petroleum(Oxy) CEO Stephen Chazen said Thursday a search for his successor is going slowly and he may stay on longer than was anticipated when his retirement plans were announced last year (see Daily GPI, Feb. 19, 2013). In response to a question during an earnings conference call, Chazen said Oxy’s board will make a progress report in February, “but I expect to be doing significantly more of these [quarterly] calls than I had planned.”
