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.
14 key comparisons between Multistage Unlimited, plug & perf, and ball-sleeves completions.
Sliding sleeves and annular fracs for fast, efficient completions
The Multistage Unlimited sliding sleeve/annular frac system combines resettable frac isolation with our exclusive Grip/Shift sliding 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 sliding-sleeve option is ideal for these completions. Read more
New 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 sliding 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
Refracs becoming more important
As multistage completions in shales and other tight formation mature, it is becoming clear that many zones require restimulation to restore initial production. Even in many new completions, insufficient stimulation has resulted in disappointing production results. The Multistage Unlimited ReFrac System is a fast, cost-effective way to isolate and refrac those underperforming zones on a single trip on coiled tubing. Read more
