Manufacturers of Oilfield Drilling Equipment.

Products include Log-O-Graf, Mud-O-Graf and Pit-O-Graf.

Log-O-Graf is a completely mechanical method of recording graphically the rate at which the bit penetrates the formation. It records footage drilled only. There is no necessity of replotting for the purpose of correlation with other logs.

Mud-O-Graf provides an automatic and continuous record of the weight of mud in the circulating system of a drilling well. Better mud control can be maintained by observing such a continuous record. 

Pit-O-Graf constitutes an accurate method of recording mud pit level on a 24-hour basis. It is entirely automatic in operation, and consists of two parts, namely the recording unit and the indicating and transmitting unit.

Has product images, illustration, descriptions, applications and specifications provide product details.
