OptiPac service mechanical packer
Save time on Alternate Path gravel-pack services with instantaneous packer setting, and enable future water and gas shutoff.
OptiPac openhole Alternate Path gravel-pack service uses shunt-tube technology to ensure maximum gravel-pack efficiency, regardless of conditions such as low fracture gradients, reactive shales, thief zones, washouts, and filtercake plugging that would otherwise result in bridging and incomplete packs. Insufficient packing can lead to erosion hot spots, increased sand production, hardware damage, and completion failure.
The service is highly effective for packing long intervals in vertical, deviated, or horizontal wells; high-flow-rate wells; low-fracture-gradient formations; wells with high-permeability thief zones where annular bridging is a risk; and wells requiring zonal isolation packers. Specially developed fluids, state-of-the-art modeling software, and pumping services are used as part of the integrated service to ensure full, uniform gravel packing across the entire interval.
The OptiPac service can be used with a viscosified polymer-based fluid or one of several polymer-free viscoelastic surfactant gravel-pack fluids, allowing the treatment to be tailored to a wide range of well types and reservoir conditions.
OSMP OptiPac service mechanical packers are equipped with Alternate Path shunt tubes for multizone openhole gravel packing. The fast-setting packer eliminates the delays associated with waiting on swell packers to set and the risk of pumping gravel before swelling is complete, which can cause the gravel to enter the packer element–wellbore annulus and prevent an effective seal.
Other components of the OptiPac service are the pumping and mixing services that allow synchronization and remote control of key equipment and precise control of sand concentrations at design values.
MUDSOLV NG integrated filtercake removal service is used to tailor the most effective cleanup strategy. The goal is to minimize screen plugging, impaired well performance, hardware-damaging hot spots, and corrosion.
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.
OptiPac screen and antiswab tool eliminate an extra run, saving rig spread costs in a deviated high-temperature well with low fracture gradient, offshore India.
Integrated approach optimizes operations and prevents premature screenouts in long horizontal sections with reactive shale and depleted zones, offshore Malaysia.
Open hole gravel packing of reservoir sections drilled with oil based fluid is traditionally performed with an aqueous carrier fluid. This typically involves displacing oil based fluid to aqueous fluid once the gravel pack screen is in place.
