Don't confuse Skypetrol,ChinaPetroTech,Chinaoilfield,etc with Sinostar..Chinapetrotech has its accounts qualified as many its receivables remain in doubts over its collectability and ChinaPetroTech provides IT solutions to oil & gas firms only..while Chinaoilfield is slightly as it provides technology and chemicals to squeeze more oil out of oilfields with remaining life of between 15 to 20years..sky petrol involves mainly 978.4%) with technical oilfield services and only 19.5% is extraction and sale of crude oil and balance provision of oil drilling tecchnology.

Only Sinostar supplies petrochemical and LPG natural gas extraction..and Sinostar's profit is way above chinapetrotech and Skypetrol but comparable to Chinaoilfield(SS 20mil-2006 ) verses Sinostar's (S$22mil-2006)



Sinostar will shine and it is a matter of time only..good candiate for value investing..ignore its up and down but buy for long term as Dubai Inv and lehman Bros are also one of its major investors and they're in for long haul.Dubai Inv has sold Skypetrol recently
