| Halliburton improves high-pressure reservoir evaluation Halliburton announced at the 2007 Offshore Europe Exhibition and Convention in Aberdeen, Scotland, the successful deployment of its Armada sampling system. The system was used to capture bottomhole samples of reservoir fluid for Oilexco North Sea Limited. The pipe-conveyed Armada system was loaded with nine samplers for Oilexco to run a drillstem test at 228 degrees Fahrenheit and 3,500 psi well conditions. All nine samples were collected and were transferred in a controlled environment on location. A second well was also successfully sampled at bottomhole temperature of 260 degrees Fahrenheit and 10,170 psi bottomhole static pressure proving its high-pressure capabilities. The goal was to optimize the reliability of reservoir evaluation by gathering samples uncontaminated by drilling fluids while expediting turnaround time and dramatically enhancing safety by eliminating the use of wireline. The Armada sampling system is specifically designed to require minimal rig-up and run-in time and operate in normal or hostile cased hole environments for extended periods of time. Because samples are maintained in a single phase, the sampler also eliminates lengthy surface re-combinations. These key design features enable operators to benefit from optimizing their rig time by reducing expenses while increasing the accuracy of the reservoir performance model. write your comments about the article :: © 2007 Construction News :: home page |
