Some people are saying the LWD data news announcement was not positive enough...........sorry, you really need Wireline Logging to be sure of anything and to be able to announce to market a discovery or not.

An example here is where LWD indicated oil show and pay, however the wellbore had stability issues and so, without doing Wireline Logging the LWD is insufficient.to draw any conclusions at all.

..........................Rockhopper Exploration plc (AIM: RKH), the North Falkland Basin oil and gas exploration company, notes the following announcement from Desire Petroleum plc (the "Operator") regarding the 14/15-1Z sidetrack well on the Rachel prospect (Rockhopper: 7.5% working interest):

Clean out of the sidetrack has not proved possible due to mechanical failure of the wellbore and it will therefore not be possible to obtain any wireline logging data from this well. However, the data acquired during drilling operations (from logging while drilling tools and geological data from cuttings) indicates that around 25 metres of sand with oil shows was encountered. However, in the absence of wireline logging data it is not possible to fully assess the significance of these results and, in particular, reservoir properties and the hydrocarbon saturations associated with these sands cannot be confirmed..............................
