LWD Tools

Primary formation evaluation is an essential part of petrophysical modeling for oil companies, when assessing reservoir potential. Logging-While-Drilling (LWD) technology provides operators with real time formation evaluation data during the drilling of a well with sensors that are included in the BHA. Information is sent to surface in real time and the tool simultaneously acquires and stores the data in memory for later download and presentation of high resolution logs. The use of LWD technology becomes of particular importance when traditional wireline measurements cannot be easily attained.
 
Gamma Ray
The Geolink Gamma Ray tool can be attached to the MWD string below the Directional Sensor in order to measure natural gamma radiation from the formation, which enables basic sand/shale detection. The patented scintillation detector design provides a highly reliable measurement and has been developed to withstand the high levels of shock and vibration usually encountered during drilling operations.
