The reason is that both companies (OSH and STO) release their weekly drilling reports around this time each week....you should expect both OSH and STO to release their reports to the market in the next few hours...
It's the usual flow of the market prior to these reports. STO should have something on the result of Khefren (among others) as it should be approaching Target Depth by now... OSH will probably have something further to offer about Nabrajah
