... in such configurations are greatly improved, thus substantially prolonging the service life of the chokes. Moreover, the pressure in the flowline during operation is significantly lower than that with configurations using a subsea choke only or a subsea choke and a topside choke. Consequently, the hydrates plug risk...

... policies require all generated wastes to be disposed in a responsible manner. Such process requires the adequate management of wastes generated during drilling operations including cuttings, excess drilling fluid, contaminated rainwater, produced water, scale, produced sand, and even production and cleanup...

... processing facilities are in operation in the United States and Canada, with a major expansion recently completed in Canada. Ensyn initiated petroleum processing in 1997. A petroleum pilot plant built in 1998 has been used for testing crude oil from around the world. In December, 2004, Ensyn initiated...

... from heavy oil to gas condensates. This paper describes the lessons learned about the practical reliability, accuracy, and operability of the MPFM meters. The paper illustrates with field results the benefits of implementing the multiphase metering in the region. MPFM meters have proved...

... Abstract The removal of sulfate from injected seawater for waterflood and pressure maintenance operations has become widely accepted for reservoirs with sulfate scaling potential. The technology has been found to be exceptionally useful in deep water and subsea operations where scale controls...

... was developed and implemented, as a result of process mapping based on signature pressures from pressure decline. Their characterization represents a major step in mitigating risks posed by waste injection, providing not only engineering understanding valuable to overall drilling operations planning, but also...

The combined application of these technologies is changing operations in the Mexico South region by improving the success ratio of primary isolation of the wells...

... reservoir management. Greater reliability, higher temperature ratings, lower costs, a wide range of sensor types, and efficient data management and analysis allow operators to exploit the technology and extract more value from production data. Recent advances have yielded smaller, less-expensive, and more...

... memory for processing at the surface after tripping out of the hole. With 5-s sampling of all average and quadrant information, the memory can accommodate up to 140 hours of data. Battery capacity is sufficient to operate the tool for 200 hours continuously at an average temperature of 200°F. When...

... Abstract It is generally accepted that the success of underbalanced drilling (UBD) operations is dependent on maintaining the wellbore pressure between boundaries determined by the formation pressure, wellbore stability, and the flow capacity of the surface equipment. Therefore, the ability...

... and temperature. These factors have led PEMEX to seek out new technology in an effort to optimize drilling and producing operations. One of the special projects defined for the year 2001 was to evaluate the application of running a high-accuracy gyroscopic directional survey instrument in tandem with PEMEX...
