Manufacturers of Oilfield Equipment.

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

The 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. 

The Mud-O-Graf is now in its seventh year of field application. Essentially, it 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.The Pit-O-Graf is in its third year in the field. It 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, description, application and specifications to provide product details.
