Methods, Procedures, Process The project utilized a digital temperature sensor (DTS) fiber optic line installed along the 5,000...

... and several perforation stages is used to provide well inflow. The impacts of reservoir deliverability, GOR, pressure and temperature are studied for all well geometries. The simulation results offer some valuable insights into the effects of well trajectory on production performance, including borehole...

.... Compared to the warm-back effect in the non-fractured region after shut-in, a less significant heating effect is observed in the fractured region because of the warmer fluid away from the perforation moving into the fracture (after-flow). Detailed parametric analyses are conducted on after-flow velocity...

... Abstract Production logs from horizontal wells in shale reservoirs indicate that more than 30% of the perforation clusters do not contribute to production. One major reason is recognized as the stress shadow effect which impedes the propagation of the interior fractures within a single fracture...

... changed after each shut-in. Perforation operations in the open annulus sections above a completed stage did not indicate proppant inflow through the new perforations. The drill out of plugs in the open annulus section circulated trace amounts of untreated proppant. Initial flow back operations showed...

... situation depends on many factors, including the type of well completion, perforation pattern, zonal isolation method, and stimulation technique. Selection of the most appropriate diversion method is also influenced by variations in formation permeability or stress contrasts along the interval to be treated...

... into account that in cooler formations, longer times are required to achieve complete degradation. Its independence of the wellbore geometry has increased the implementation in openhole and cased-hole completions, despite the final shape of the perforations. production monitoring Completion Installation...

... The basic idea of the system is to extend tailpipe down across the perforated interval, below a conventionally set production packer. Along the tailpipe, carrier subs containing pressure regulators are spaced out and used to inject trapped formation gas beneath the packer into the production...

The challenges for the ESP system for this specific test included: (i) motor cooling restriction due to absence of adequate rathole; (ii) production from multiple perforations over 600 ft spread; (iii) low liquid flow (<400 BPD); (iv) high gas-liquid...

... diameter (ID) limited the available methods of shutting off water in slimhole monobore commingled wells. In the past, the operator would perforate, fracture treat, and flow test each zone separately. Because of this completion practice (long cycle times) along with a shortage of personnel, equipment...

The effectiveness of this connection is the result of perforator selection criteria and the well environment in which the perforating job is executed. In the depleted oil field under study a typical completion is perforated using large Tubing Conveyed (TCP) guns...

... Abstract Fracturing is an important technique for stimulating production in low-permeability formations, and requires special consideration in designing the preceding perforating job. Aligning the perforations along the direction of maximum geological stress, known as the preferred fracture...
