| 20090090176 | ELECTROCHEMICAL SENSOR - An electrochemical sensor for measuring contents of a fluid or gas at high pressure and/or high temperature, for use, for example, in a wellbore for hydrocarbon applications, is provided. The sensor includes: a bulkhead-like electrode assembly including a cylindrical housing and a cylindrical electrode structure. The cylindrical electrode structure includes a cylindrical conductive pin extending from a high pressure region to a low pressure region and an electrode connected to one end of the pin at the high pressure region and having an electrode surface for exposure to a flow path of the fluid or gas in the high pressure region. At least a part of the surface of the pin is protected from direct contact with the fluid or the gas by an insulating coating impermeable to the fluid or gas. The pin may include an alternating pattern of protruding and receded portions. | 04-09-2009 |
| 20090166085 | DOWNHOLE FLUID ANALYSIS - A method that uses downhole fluid analysis in order to selectively collect and retain formation fluid samples in a drilling environment, as well as, control drilling using downhole fluid analysis. | 07-02-2009 |
| 20090287451 | METHOD AND SYSTEM FOR AZIMUTH MEASUREMENTS USING GYRO SENSORS - A method and system for azimuth measurements using one or more gyro sensors is disclosed. The method includes acquiring a first data from each of the gyro sensors with an input axis aligned to a first angular orientation and acquiring a second data from each of the gyro sensors with the input axis flipped to a second angular orientation opposite to the first angular orientation. An earth rate component at the first angular orientations is determined based on a difference between the first data and the second data to cancel out bias of each of the gyro sensors. The method may include acquiring a third data of the gyro sensor with the input axis aligned to the same angular orientation as the first angular orientation. An average of the first data and the third data may be used instead of the first data for determining the earth rate component. | 11-19-2009 |
| 20100223796 | APPARATUS FOR AZIMUTH MEASUREMENTS USING GYRO SENSORS - An apparatus for azimuth measurements is provided. The apparatus comprises a housing and a plurality of gyro sensors aligned in the housing. Each of the plurality of gyro sensors has an input axis for angular velocity measurements. There is provided a drive unit for rotating each of the plurality of gyro sensors about a rotation axis. Each of the plurality of gyro sensors changes orientation of the input axis with the drive unit. | 09-09-2010 |
