OptiPac XL Extended-Length Alternate Path Gravel-Pack Screen
Using enhanced shunt screen technology
Reach more reservoir rock with fewer wells by enabling long, multizone gravel packs.
Openhole Alternate Path gravel-pack service
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.
Effective zonal isolation with OSMP packers for openhole gravel packs reduced well count and costs and increased ultimate recovery in deepwater wells.Read case study
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.
