1 MINImal Series Overview The Lodestar MINImal series is the industry s most technological advanced MWD system; capitalizing on innovations such as in MEMs accelerometers and ARM magnetometers to deliver market leading accuracy while dramatically reducing the overall package size. These innovations allow Lodestar to provide one core tool MicroPulse with the flexibility to accomplish Survey on Connection (SOC), D&I and Gamma. Futhermore, the MINImal Series seamlessly integrates with Lodestar s LRes-175 and other 3rd party Rotary Steerable and LWD Systems. Lodestar provides a solution with: MINImal Connections MINImal Failure Points MINImal Size MINImal Weight MINImal Logistics MINImal Cost This means your investment and effort in operations is MINImal. MINImal Retrievable MINImal Top Mount MINImal RFD 1

2 MINImal Series With the advent of the MicroPulse Technology, we can manufacture the world s smallest Directional Module at 16. This allows Lodestar to drastically reduce the overall length of a traditional MWD tool. What makes this possible? MEMs Accelerometers (MicroElectroMechanical): Technology smiliar to what is found in your phone is now ready and rugged enough for downhole use. Taking advantage of the small size, nine MEMs accels have been installed into the system. This means that up to four accels can fail and still enable the user to accurately drill ahead. AMR Magnetometers (Anisotropic MagnetoResistive): Incorporating AMR mags provides the same accuracy while providing a far smaller footprint and lower cost. Power Consumption: With the low power consumption of the MEMs accels and AMR mags, there is no need for a triple power supply. A common failure point among traditional MWD systems. In addition, the battery size can be reduced due to the lower power demands. Integration: Condensing over five circuit boards found in traditional MWD designs down to a single circuit board with built in sensors; thus reducing connection points, cost and failure nodes. 2

3 MINImal Series Don t let your supplier give your next great idea to the competition! External Development: MicroPulse will allow the end-users to write their own telemetry scheme in a simple programming language which would be compiled on the desktop and loaded to the MicroPulse. The directional measurements and relevant system measurements would be available through the programming interface, allowing users to write their own telemetry and encoding algorithms. Durability validated in the harshest enviornments 15,000+ down hole circulating hours Over 150+ wells completed Highly Accelerated Life Test certified Temperatures from -85C to 200C Vibration levels of 40 Grms to 80 Grms 3

4 MINImal Top Mount Series Lodestar presents the answer to working with LWD systems. The MINImal Top Mount series allows users to work with the LRes-175 and LAB-175. The Top Mount Series can also work with many other third party LWD manufactureres. Utilize existing UBHO sub fleet Rated above 100lbs/bbl LCM MINImal wash points Pulser, Gamma and Micropulse all housed in single barrel Low Power Consumption for longer battery life Ready to Connect to LWD systems Ability to achieve higher data rates ~ 1.5 bps Robust design for harshest drilling conditions Can be swapped between multiple collar sizes while in the field Flow rate adjustments can be made in the field The rotor is all that needs to be changed for various flow rates and can be done at rig site. Pulse Driver MicroPulse Electronics Package Length 106 (269 cm) Gamma The toughest pulser on the market. If you can pump it, we can pulse it. 4
