Earlier, a Dow Jones Newswires report said that Shell was seeking bank advice regarding a possible bid for Premier Oil, citing people familiar with the matter.
Dealers seemed to think a bid unlikely as Premier shares traded down 0.43 per cent at 1,038 pence at 0847 GMT, compared to a flat DJ Stoxx European oil and gas sector index.
However, some industry executives do not believe Premier management would be keen on a sale. Mr Lockett took over as chief executive officer just 17 months ago and brought a new management team with him.
