The first exploration wells in an area are generally used as a reference. Available information often includes old 2D seismic prints, blue prints of old logs, SP logs, and handwritten biostratigraphical age dating and drillers information.

We are specialised in restudy of  this historical material to make it accessible and comparable with present day formats, thus enabling meaningful correlation with new wells and enhancing present day geological studies. Of course this type of information is incorporated in all studies we perform.

Prior to the drilling of a new well it is especially important to have a good set of off-set well logs including all available information.
