Completions
Industry experts at URTeC assessed more than a decade of unconventional growth while discussing where productivity gains will come from next.
Chevron and Halliburton describe how they built and deployed the fully autonomous closed-loop fracturing system that enables subsurface-driven optimization.
Weatherford CEO Girish K. Saligram said the acquisition will bolster Weatherford’s completions offerings and unconventional reservoir capabilities.

Use of a complex-nanofluids (CNF) additive to hydraulic fracturing fluids has doubled even as activity has fallen because of potential production increases. -
This study compares the performance of openhole-packer completion systems with that of cemented-liner completion systems in the northern Montney gas resource play.
-
Operators continue to look to prolific high-permeability, clastic reservoirs in basins around the world. The use of high-deviation and horizontal well trajectories in these fields improves productivity but increases the challenges of sand control.
-
The engineering and operational planning to ensure that no uncontrolled hydrocarbon releases occur during the execution of subsea big-bore gas wells are described.
-
Dubai Petroleum embarked on a new mission last year to drill and complete its first multistage, hydraulically fractured, and propped horizontal well from an offshore platform.
-
Saudi Aramco has begun moving toward the production phase of its ambitious plan to develop its enormous hoard of unconventional gas resources.
-
Could the development of consistent practices be a critical first step on our journey toward achieving improvements in completion quality? The list of practices is quite long. For sand-control applications, we could start with those activities that occur early in the design process.
-
In organic shales, hydraulic fracturing is important for optimizing the production of horizontal wells. For a standalone lateral, the propped surface should be maximized to increase production. In the case of a pad, well spacing is an additional factor.
-
This paper offers an alternative explanation for the early boundary-dominated flow related to dissolution of salt-sealed natural fractures in the shale.
-
On the basis of production data, diagnostic methods, and field observations, it is becoming increasingly clear that induced unpropped fractures created during the hydraulic-fracturing operation play a critical role in determining the success of fracture treatments.
