New screen system helps solve completion problems
The new DIRECT PAK screen system has been developed to provide solutions to two major sandface completion concerns: hole instability in horizontal open-hole gravel packs and annular bridging during long-interval cased-hole fracs.
The design provides:
• An additional flow path for slurry transport should annular bridging occur while packing.
• Maximum mechanical strength while minimizing the OD.
• Simple construction that helps ensure reliability.
• Fast assembly that helps minimize rig time and doesn’t require special timed connections.
• A spiral design that helps centralize the screen and evenly distribute sand slurry to reduce the possibility of annular voids.
The company says its system has been applied effectively in open-hole, gravel-pack completions in deepwater, high-rate gas wells in the Middle East.

New analyzer maintains gas quality control
AutoCO2 is a new carbon dioxide analyzer for natural gas operations.
The unit measures CO2 concentrations in natural gas to maintain gas quality control at delivery points. It provides well and pipeline control to the producer, gathering station operator, or transmission line technician. Furthermore, multiple units can be installed on several incoming lines to monitor, blend, or restrict certain production runs to the gathering station.
The analyzer detects CO2 in natural gas using nondispersive infrared technology. The basic principle of operation is to detect the volume of energy at a specific wavelength that is absorbed by passing natural gas between the infrared optics and sensor. The amount of energy absorbed is directly proportional to the concentration of the simple target and the path length for the energy. Also, the “intelligence” to log data, alarm, and control well functions stays in the flow computer and is not duplicated in the sensor. The AutoCO2 is easily installed at the meter run by utilizing a sample probe with regulator.
