Industry experts at URTeC assessed more than a decade of unconventional growth while discussing where productivity gains will come from next.
The technology has passed its first phase of qualification, with 84 nodes placed on the seafloor at a depth of 2,000 m to acquire 4D seismic data in the pre-salt Santos Basin.
Chevron and Halliburton describe how they built and deployed the fully autonomous closed-loop fracturing system that enables subsurface-driven optimization.

Saudi Aramco’s papers on new well technology offer glimpses at the challenges of developing its unconventional gas resources. -
The challenge is immense, but the promise is, too. If the oil and gas business can scale up CO2 EOR, then it can play a very big role in mitigating climate change while offering carbon-negative fuels.
-
Engineers thrive on making more from less, and this month’s paper selections highlight efforts to improve the efficiency of gas-production operations throughout the world.
-
Advances during the past decade in using convolutional neural networks for visual recognition of discriminately different objects means that now object recognition can be achieved to a significant extent.
-
When a plug gets stuck in a well, consider the cause. Often stuck fracturing tools are a warning sign of casing trouble. Companies that have investigated plug problems have been surprised by the findings.
-
Though shelved by low oil prices, the plan to execute the largest enhanced oil recovery program of its kind offers insights into what it may take for the shale sector to escape pilot mode and scale up gas huff ’n’ puff operations.
-
The complete paper discuses a well with a history of sand production that exhibits long cyclic slugging behavior.
-
Automated image-processing algorithms can improve the quality and speed in classifying the morphology of heterogeneous carbonate rock. Several commercial products have produced petrophysical properties from 2D images and, to a lesser extent, from 3D images.
-
With reduced new unconventional well activity, practices such as frac-hit mitigation—pressurization of parent wells during child-well fracture stimulation—have become increasingly important to reduce parent-well proppant cleanouts as well as to maximize production from both parent and child wells.
-
This latest find means the offshore driller has averaged at least three new discoveries each year since it began drilling offshore Guyana where it plans to recover up to 8 billion barrels of crude.
