While sand control in production wells catches much attention, water-injection wells also are subject to sand-control problems triggered by water hammer, cross flow, and backflow. Newly developed screens for water-injection wells have been demonstrated with promising results. -
On the technology side, regardless of the oil price, demand persists for cost-saving and value-adding innovations and emerging technologies to bridge gaps in the existing technology portfolio for sand management and control.

Production from sand-prone reservoirs is one of the more daunting tasks, with formidable challenges. Sand management and control remain as an old problem but with new challenges because of the suppressed oil and gas prices. Cost-saving and value-adding solutions are vital now more than ever.

Natural gas had a bullish year in 2016 as the average Henry Hub spot price jumped from USD 2.28/million Btu in January to USD 3.59/million Btu in December, according to the Energy Information Administration. It also positively forecast that the gas price will rise to USD 3.67/million Btu in 2017.

Despite the currently deteriorating oil and gas prices, natural gas, the “least carbon-intensive” fossil fuel, is still projected by ExxonMobil, the International Energy Agency, and other sources to grow by 65% from 2010 to 2040

Among the top 10 largest discoveries in 2013, half of them are natural-gas discoveries and all of them are in offshore environments, primarily in Africa, Far East Asia, and transcontinental countries, with estimated resources of more than 4,000 million BOE.
-
In the next 20 years, there will be a large increase in global natural-gas demand, with an average growth rate of more than 1.8% per year. The top two leading countries in rising gas demand are China (7% per year) and India (4.7% per year).
