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.

This paper will discuss the hydraulic-fracturing-stimulation design, execution, and evaluation for the first successful proppant-fracturing treatment in an unconventional carbonate source rock in Saudi Arabia. -
Low oil prices look like something the industry needs to get used to. “This will be with us for a while,” said Rex Tillerson
-
The oil industry has responded rapidly to the decline in oil prices of these last few months.
-
Today, there is a need for higher-strength coiled-tubing (CT) grades with better resistance to severe environments and better fatigue performance in both the tube body and the bias weld.
-
Microbial-influenced corrosion (MIC) has been implicated in few corrosion-related challenges in the well-service industry in the past.
-
A common problem in oil and gas wells is excess free gas or water production from only certain portions of the completed interval.
-
The technical contributions highlighted this year focus on matrix stimulation of carbonate and unconventional reservoirs.
-
Core-flow tests are usually conducted to test and model stimulation treatments at laboratory scale, to predict the performance of such treatments in carbonate reservoirs.
-
Mechanical-diversion techniques can ensure acid injection into the various intervals of naturally fractured reservoirs.
-
An operator developing tight carbonate reservoirs found that conventional acid stimulation with 15% hydrochloric acid (HCl) in horizontal wells did not provide expected results.
