SureShot™ MWD Gamma Sensor

|
The APS SureShot gamma sensor employs a rugged scintillation counter and photomultiplier mounted in a specially-designed package which provides protection against the high levels of shock and vibration encountered in the drilling environment. APS's natural gamma ray sensor module is an add-on to our SureShot Measurement-While-Drilling (MWD) system. The APS gamma sensor is calibrated to API-standard units, and a wellsite check source is available to verify tool performance in the field or maintenance repair shop. The easy-to-use SureShot surface system scales natural gamma ray data to API units; corrects for borehole size, mud weight and drill collar effects; assigns each point a depth from the depth tracking system; and plots both real-time displays and configurable hard copy logs. Data can be exported in standard industry formats (WITS and LAS).
The SureShot MWD downhole system can be programmed to send a combination of gamma ray and tool face data transmissions to allow logging while steering and sliding. A rotation sensor in the directional package enables the tool to optionally transmit only gamma ray data while rotating. The SureShot MWD can store up to 32 MB of gamma data for retrieval during trips.
| Features | Benefits | Advantages |
|---|---|---|
| Modular addition to SureShot system | Gamma ray service can be easily added | Reduced inventory cost and service flexibility |
| Ruggedized industry-standard design | Reliable | Low cost of maintenance |
| Calibrated to the API Standard | Direct correlation to wireline logs using API units | Improved geologic correlation |
| Electronic data export and import | Gamma ray and other log data can be shared with other packages or transmitted to customer's office | Services can be easily integrated with other wellsite services and data can be transmitted to decision makers quickly |
| Depth tracking using APS depth tracking system, WITS-based rig site or 3rd-party system | SureShot system is flexible and can receive depth from various WITS-based systems | Depth tracking hardware usually not needed on rigs with a 3rd-party, WITS-based depth system |
| Standard module | Same module used in BHAs for 3.5 to 8 in. (89 to 203 mm) and larger collar sizes | Reduced inventory cost and service flexibility |
