OptiPac service mechanical packer
Save time on Alternate Path gravel-pack services with instantaneous packer setting, and enable future water and gas shutoff.
Alternate Path systems use shunt tubes and nozzles to create an alternate flow path that allows slurry to bypass bridges and fill in voids that can occur when gravel and frac packing. Options are available for both cased hole and openhole wells.
Each system is composed of a screen with shunt tubes, fluid systems with specific requirements, and a customized pumping design. The system helps increase completion longevity and reliability by ensuring a complete annular pack, thereby reducing the risks of erosion hot spots, hardware damage, screen and gravel-pack failure, and deterioration in well productivity.
Screens designed for the OptiPac Alternate Path gravel-pack service are available to suit the characteristics of the reservoir and the wellbore to be gravel packed. Both wire-wrapped and premium sintered mesh versions are available.
The screens are designed with one or two transport tubes that are nonported and move the slurry from joint to joint. Each joint also has two packing tubes equipped with nozzles that divert the slurry to the open hole between the screen and wellbore when bridges form, allowing the empty spaces to be filled.
UltiPac Alternate Path extended-reach gravel-pack screen has unique round shunt tubes to minimize frictional losses and increase the gravel-pack length to more than 6,000 ft [1,829 m]. Each screen is equipped with six transport tubes and three packing tubes, all encased by the screen wire for protection so that the screen can be fully rotated while running in. The screen uses the same wrapped wire as the robust and precisely manufactured direct-wire-wrapped screen.
Zonal isolation with the hydrostatically set OSMP OptiPac service mechanical packer—which is equipped with Alternate Path shunt tubes—enables multizone openhole gravel packing. The packer sets in a matter of seconds, eliminating the long wait times that result when using swell packers for zonal isolation. Rapid setting also precludes the possibility of prematurely pumping gravel before sealing is complete, which can lead to insertion of gravel between the packer element and the borehole wall and consequently, an incomplete seal. Gravel packing nonproductive zones can be avoided, saving time and costs.
AllFRAC Alternate Path cased hole frac-pack screens can handle higher treatment rates and are suitable for frac packing. Wire-wrapped and premium sintered mesh versions are available. These screens can be used with conventional gravel-pack systems as well as single-trip perforating and gravel- and frac-pack systems.
Integrated approach enables successful packing of 4,347 ft of open hole in a challenging environment with low fracture pressure.
10K antiswab service tool with MudSOLV service module eliminates extra trip to remove filtercake in openhole gravel-pack completion.
Effective zonal isolation with OSMP packers for openhole gravel packs reduces well count and costs and increases ultimate recovery in deepwater wells.
Integrated approach optimizes operations and prevents premature screenouts in long horizontal sections with reactive shale and depleted zones, offshore Malaysia.
Production increased by 90% and water cut reduced to 20% in first three months, proving feasibility of reviving Malaysian brownfield.
