Directional Drilling

Directional Drilling advantages:

– Sidetracks – Multiple sidetracks – Spacing considerations – Multiple wells from single structure or pad – Inaccessible surface location – Directional drilling and sensors allow for less environmental impact.

What is Directional Drilling:

Any drill hole that the contractor attempts to change or alter the azimuth or inclination

Instrumentation Scotland & Offshore Systems, 8 – 9 September 2010 MEMS Motion Sensors for Drilling Applications 10

To hit the geological target To avoid other wells To allow efficient drilling of a relief well

Advantages of accurate Downhole Survey in exploration, mining, tunnelling, site investigation are:

Increase your profits Reduce exploration time

Why do we need Downhole Surveying?

Instrumentation Scotland & Offshore Systems, 8 – 9 September 2010 MEMS Motion Sensors for Drilling Applications 11

Typical sources of hole deviation in surface or underground drilling:

1 Incorrect marking and collaring 2 Faulty inclination and directional settings 3 Use of wrong drilling tools or parameters 4 Natural deviation due to geological conditions 5 Incorrect hole depth measurements 6 Under gauge, omitted, or lost holes

Conclusion – 1 Temperature range up to 150°C

Products are ideal for Harsh Environment and Drilling applications:

– Tilt measurements for Directional Drilling and Borehole Survey – Higher g ranges for vibration and shock + possible tilt redundancy and signal cross check

Excellent temperature performances between -55°C and 125°C

– Performances inherited form inertial grade products and harsh environment applications are beneficial to many drilling applications

Standard products are extremely robust and can be used up to 150°C

– The temperature behavior is impacted but remains very repeatable – Some extra qualifications are required to validate independently each product

Instrumentation Scotland & Offshore Systems, 8 – 9 September 2010 MEMS Motion Sensors for Drilling Applications 23

Conclusion – 2 Temperature range up to 200°C

The MEMS technology is suitable for extreme temperature (typ 200°C)

– High temperature operation does not induce drift: Bias measured at 20°C remains stable within 1 mg. – At high temperature the electronics (temperature sensor and ASIC) does not work properly

Preliminary measurements indicate:

– MEMS sensor is not degraded by high temperature cycles (up to 200°C) – Current electronics is not designed for and does not operate properly at high temperature New dedicated electronic needs to be redesigned (SOI techno)
