Hart Energy reports that Ohio's lack of transparency on drilling production data may slow development in the Utica shale.



Thomas Pritchard of California-based Imperial Capital LLC saidat a Pittsburgh conference that the lack of production data from Ohio is troubling, Hart Energy says.



Ohio requires once-a-year production totals in March.



To date, companies have offered preliminary data on only 16 wells.



To date, Ohio has permitted 457 wells, of which 187 have been drilled. A total of 45 are in production, as of Nov. 24.



A total of 29 rigs are working in Ohio,
