Intelligent completions could improve many of the world’s oil and gas wells, but not all are suited to the technology. There is another option.
Casing deformation has emerged as a major challenge in China’s unconventional oil and gas fields, prompting the development of new solutions to address the issue.
The US supermajor is using one of its lowest-value hydrocarbon products to generate double-digit production increases in its most prolific US asset.

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.
-
Disruptive technological advances may produce significant improvements in completion techniques.
-
Multilayered metal-mesh screens (MMSs) are widely used as standalone screens for sand control in unconsolidated formations. It is often found that screens with the same filter-layer nominal rating perform differently.
-
This paper presents a combined experimental and numerical-modeling study on sand-screen performance. The objective is to develop an improved methodology for optimal sand-screen-aperture selection by addressing some of the limitations present in existing sand-retention tests.
-
In this paper, gravel-pack pore size is evaluated further by use of the permeability of the gravel pack and other methods. A new sizing method is proposed that is based on the effective formation size and the gravel-pack pore size.
-
One study is showing that when pumping a proppant into a fracture, a little bit of extra effort might increase performance.
-
As activity plummeted to record lows, we witnessed a calibration of completion strategies. Whether it was further optimization of the preferred completion technique, implementation of new technologies, or a complete shift in completion philosophy, no stone was left unturned.
-
This paper documents the success story of the first quadlateral completion for an Alaskan operator by use of stacked, rotatable, Technical Advancement for Multilaterals Level-3 junction systems.
-
In this study, the authors demonstrate a reliable, cost-effective methodology that empowers shale operators with reservoir data on every well.
