Drilling fluid is critical for successful oil extraction. Typically made up of water, clay and a complex mix of chemicals, it supports the drilling process in a variety of ways — from lubricating and cooling the drill bit under high-temperature and high-pressure conditions, to lifting drill cuttings to the surface, to maintaining oil well stability and safety. But drilling fluid is not a “one size fits all” solution. To work properly, the fluid must be optimized for the unique geographic conditions of individual well sites.
In oil/gas production, refining and storage operations around the globe, flare gas systems are used to burn-off and dispose of waste, excess or off-gases, and as a safety system. The accurate, responsive and reliable measurement of flare gas is essential in order to assure proper operation of the flare gas system, which protects people and equipment from potentially hazardous combustible gas to maintain a safe working environment and to avoid environmental contamination.
Reliable monitoring and treatment of water in oil refineries is essential for the production of petroleum-based products, including gasoline, diesel, kerosene, heating oil, and byproducts for plastics and a variety of lubricants. There are three process areas within refineries that require large amounts of water: cooling units, desalter units and wastewater treatment
Misinformation about WirelessHART networks prevails among many instrument engineers in the process industries. This article attempts to set the record straight by debunking seven myths about these networks.
There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.
The City of St. Cloud, Minnesota, straddles the Mississippi River near the center of the state a little more than 65 miles north of the twin cities of Minneapolis-St. Paul. The city’s forward thinking staff began looking for sustainable green energy solutions in 2003. After planning and initiating a series of projects over several years, the site is today producing renewable energy with a 20 kW rooftop solar array, a 220 kW solar array and biofuels electricity generation.
When the plant team at HollyFrontier’s Woods Cross Refinery, near Bountiful, Utah, needed mass flow meters to measure flare gas to the main flare header, the team drew on its past metering experiences for this difficult application.
Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.
Orpic (Oman Oil Refineries and Petroleum Industries Company) required a thermal seawater desalination solution as part of its Sohar refinery improvement project to ensure an uninterrupted supply of fresh feed water to for its boilers.
The primary fluid used in hydraulic fracturing is water and the completion process can require from 2.75 - 8.25 million gallons per well. This white paper discusses the different water management and instrumentation requirements for controlling and processing drilling mud, hydraulic fracturing fluid, flowback water and produced water.
An oil refinery in the Southwest United States needed to sample diesel flow during shipment to ensure that the product characteristics were uniform throughout the batch. A local hydrocarbon sampler company provided a pressurized sampler. However, a flowmeter would also be necessary to pace the taking of the diesel sample with the flow.

A hospital had been pumping their wastewater with a submersible pump for years. But after seeing the benefits of the S&L Above Grade Wet Well Mounted Pump Station, they quickly saw the benefits - easier and safer maintenance, higher efficiency, long pump life, and more. Hear from the operator himself to learn why the hospital now prefers S&L's EVERLAST™ Wet Well Mounted Pump Station.
Collaborative research is a critical element for identifying unforeseen risks associated with using the oil industry’s wastewater outside the oilfield. That’s the recommendation of a new peer-reviewed paper accepted this week in the Journal of Integrated Environmental Assessment and Management (IEAM).
We’re past the midpoint of the Texas legislative session and the bill filing deadline is behind us. Because the legislature only meets for five months every other year, there’s a lot to accomplish in a short span.
Keeping an eye on what happens with domestic oil and gas regulation is a bit like herding cats. We’ve seen encouraging progress on air quality issues related to oil and gas, but an equally critical front that’s seen major action is protection of our land and water resources.
When it comes to answering questions about whether the oil and gas industry’s wastewater can be safely reused for other purposes, like food crops, livestock, or even drinking water, there are a number of other serious factors to be considered.
Onshore crude oil production has increased in the United States over the past few years. Oil producers, specifically the North Dakota Pipeline Authority and the Bakken Shale field producers are transporting crude oil by rail and train to both the East and West Coast oil refineries. While rail tends to be one of the safer and more efficient ways of transporting crude oil, there is still a risk of a spill. Oil spills are threats to both ground and surface waters, which can ultimately impact drinking water.
Regulators from across the country met in Vermont this week at the Environmental Council of the State’s (ECOS) fall meeting to discuss some of the nation’s most pressing environmental challenges. I joined members of ECOS’ Shale Gas Caucus to discuss an emerging threat imminently impacting oil and gas-producing states: the question of what to do with the massive amount of wastewater produced by the oil and gas industry each year.
Most industries are required to remove contaminants from wastewater systems before discharge to a receiving stream or municipal facility. Depending on the industry, contaminants may be numerous or difficult to treat. Finding the most effective, cost-efficient treatment method is critical for both business and the environment.
