Hi Awax - I was contacted by email yesterday evening by a shareholder who wishes to remain anonymous but who appears to have a significant degree of industry knowledge. He asked me to contribute the following to your discussion:
He wrote:
"could you help awax and scoobybrex with respect to logging while drilling. One asks what benefit does this actually give for the company, the other answers "Logging whilst drilling is real time data collection during the drill, The alternative is wireline logging when the drill is finished with a section or the well a different tool is inserted into the well for data collection" which sounds like a copy and paste from a website. However, only wireline works with gravity, in other words the weight of the tool carries it down the well, and then it's pulled back up. Once a hole gets past a certain inclination usually reckoned to be around 65-70 deg, the component of gravity acting to lower the sonde cannot overcome the friction of the hole walls. So LWD is the only realistic method* of getting data in a highly inclined or horizontal hole section. *=there are tractors designed to pull the sonde down, but these are pretty rare. "
That is the sum of the email sent to me. It is not my technical knowledge but I hope that the information is correct and informs your discussion.
