New controlled optimization is true optimization

To truly optimize a multistage completion design for a given field and formation, you need a systematic completion approach that allows you to make well-to-well comparisons with confidence. You need consistent, repeatable frac delivery plus measured downhole data that helps you better understand the formation, the well, and the stimulation. Read more

New MultiCycle frac sleeve

The new MultiCycle reclosable frac sleeve gives you more flexibility when completing a well, managing production, and performing well restimulation or remediation. Now, you have the option of fraccing stages out of sequence, and you can close and reopen selected intervals as needed over the life of the well without having to use a costly workover rig.

New liner hanger systems

NCS Multistage introduces the Vector-Max liner hanger, a premium hydraulic-set hanger/packer for cemented applications. Now available in 4.5-in. x 7.0-in, the hanger system boasts a number of key features, including expanding metal liner-top packer seal and protection against premature release of the running tool. Also new is a Vector-Max liner-top packer only (without hanging slips) and the Vector-1 hydraulic-set liner hanger for uncemented installations. Read more

The high-efficiency alternative to plug & perf and ball-sleeves

Multistage Unlimited technology is a more efficient and more economical alternative to plug- and-perf and ball-sleeve frac systems, both of which are brute-force methods that bullhead fluids down the casing, with no feedback about formation response at the frac zone, no recourse in the event of a screenout, and no way to manage water and chemical consumption. Both methods do, however, have a huge appetite for pumping horsepower. Read more

Where do the fracs go? The quest for the most efficient field frac network

As unconventional resources development has evolved, it is clear that a key to maximum reservoir drainage is a systematic drilling pattern and an efficient field frac network that achieves maximum connectivity to the formation. This requires as many wells as possible on a given acreage, and as many stages per well as possible, without communication between stages and between wells. To achieve this, frac spacing must be exact and frac dimensions must be uniform.

Unfortunately, it is impossible to achieve either consistent frac spacing or uniform frac volume using plug-and-perforate, currently the most popular method, or with open-hole packers and ball-drop sleeves.

Casing sleeves and annular fracs for fast, efficient completions

The Multistage Unlimited casing sleeve/annular frac system combines resettable frac isolation with our exclusive GripShift casing sleeves to deliver fast, economical, and effective multistage completions. Unlimited stages and spacing, real-time frac-zone pressure, 5 minutes between fracs, and no drillouts. Read more    Watch full video

Half-Straddle option for low-rate fracs

In formations with thin reservoirs and water-bearing zones nearby, it is usually best to complete with a large number of stages and smaller fracs to avoid the water. These smaller fracs—typically 10 bpm or less—can be pumped through the coiled tubing, rather than down the coiled tubing/casing annulus. The Multistage Unlimited Half-Straddle plus casing-sleeve option is ideal for these completions. Read more

Interventionless toe sleeve

The Multistage Unlimited toe sleeve is the surest, simplest way to achieve initial formation access for multistage completions. Its delayed opening sequence allows an extended casing test before initial injection. Read more

Multistage completions using sand-jet perforating

If a well is already cased, Multistage Unlimited Mongoose technology can still provide significant economic, environmental, and operational advantages over plug & perf and ball-sleeve systems. Instead of casing sleeves, the Mongoose system uses sand-jet perforating to gain access to the formation at each stage. Sand-jet perforating works in both horizontal and vertical wellbores, either cemented or uncemented. Read more

SpotFrac system takes on refrac challenges

The Multistage Unlimited SpotFrac system is the fast, cost-effective way to remediate multistage wells by refracing underperforming zones and by adding new frac stages. Deployed on coiled tubing, the system can perforate, isolate, and stimulate multiple stages in a single trip. Read more

AirLock buoyancy system helps land horizontal casing

The simple and passive AirLock™ system facilitates landing casing strings in horizontal wells, at nominal cost and without altering casing and cementing operations. Read more
