The Flip Side of Full Oil Above Ground Storage Tanks

Many news articles have addressed the fact that low oil demand has led to above ground storage tanks becoming full, both in the US and abroad. While this is an issue in and of itself, it isn’t the full story. There are other repercussions of the oil glut, including the fact that more than 60 oil producers have declared bankruptcy since 2014. This in turn leads to the problem of abandoned wells, with the number of orphan wells across Texas, Wyoming, Louisiana, and Oklahoma running into the tens of thousands. Tools, steel storage tanks, and miscellaneous pieces of equipment

Saying Goodbye to Beautiful Above Ground Storage Tanks

In just viewing them, above ground storage tanks do little to raise the pulse. When you think of an API tank, you probably picture something big, boring, and bland; they are a classic case of function over fashion and normally a company logo is about as exciting as it gets. However, there have been examples of some fantastically decorated API 650 tanks, adorned with murals, bright colors, and other creative artwork. Recently however, there has been a trend of returning above ground storage tanks to their monotonous best and although we hate to say goodbye to these beautiful API

Above Ground Storage Tanks in Space?

Here at Heartland Tank Services we’ve constructed a lot of above ground storage tanks in locations throughout the United States and beyond under a wide range of circumstances. We’ve never really given any thought to building a tank any place but on earth, so we were intrigued to see a recent article about building storage tanks in space. Yes, you heard correctly; Mike Snead, President of the Spacefaring Institute™ LLC has been tasked with assessing the possibility of building small storage tanks in space, using minimal components and simple equipment. This interesting endeavour was featured in EngineerLive in an article “Building

Liquid Fertilizer Tanks: Shop Built Versus Field Erected

Above ground storage tanks come in unlimited sizes and can store a seemingly infinite variety of liquid products. Although it seems like tanks are not that different, one main difference is where they are built. For a liquid fertilizer tank, it is either built in the shop or in the field at the final location. Building Style As indicated by the name, shop built tanks are built in the shop of the construction company. The benefits of being a shop tank builder are always being inside, having a central location for your work force, and being able to have common sized tanks

Clean Air Act Success Requires More Sulfur Liquid Fertilizer Tanks

Several agricultural studies over the past 20 years have confirmed what farmers are discovering in the field; less sulfur exists in today’s farming fields. The Clean Air Act is the interesting cause of this sulfur decrease. In turn, the demand for sulfur liquid fertilizers and API 650 liquid fertilizer tanks to store the products is on the rise. The Clean Air Act was enacted in 1970 and amendments passed in 1990. The aim of this legislation was to significantly reduce six particular air pollutants, including the sulfur dioxide emissions from coal burning facilities. High levels of sulfur dioxide in

3 Facts About Valve Containment Boxes on Your API 650 Tank

Have you ever wondered why you need valve containment boxes on you’re API 650 tank when you already have an internal PVC tank liner, one of the state’s acceptable secondary containment options? First, states that permit internal tank liners require valve containment boxes, so there really is no choice in the matter. Nevertheless, valve containment boxes are worth every penny in protection against a product leak if an above ground tank valve fails. Talking about containment can be disheartening because it is centered on the undesired situation of part of a tank system failing or leaking. Remember though that such safety

Earthquakes, Fracking, and API 650 Storage Tanks in Cushing, Oklahoma

In recent years, Oklahoma has experienced hundreds of magnitude 3+ earthquakes annually — with each year since 2013 bringing a remarkable increase over the prior year. What is the cause of this continued increase in earthquakes? According to Oklahoma’s Office of the Secretary of Energy and Environment’s Earthquakes in Oklahoma: What We Know webpage, “The Oklahoma Geological Survey has determined that the majority of recent earthquakes in central and north-central Oklahoma are very likely triggered by the injection of produced water in disposal wells.” In other words, the practice of hydraulic fracturing, or fracking, and its byproducts is a real concern.

Repurposing an API 650 Tank: Max Fill Height and API 653

API 650 tanks are commonly repurposed to store a different liquid than what intended when the tank was originally built. This happens in every industry imaginable, because companies want to use their capital resources efficiently. The most important step in the process is to have an API 653 tank inspection performed on the above ground storage tank before the new product is introduced. The inspection evaluates the integrity of the tank and calculates the maximum fill height. When an API 650 storage tank is constructed, the design of the tank is chosen based on the liquid that will be

Draining API 650 Storage Tanks of Oil

As expected, the Organization of the Petroleum Exporting Countries (OPEC) and some non-OPEC countries reached an agreement in 2016 to cut the production of crude oil to increase prices. This cut has ended the super contango in the oil market, and API 650 tanks are starting to be emptied to put the oil on the market. A contango is when the current price of a commodity does not reflect its actual value. This results in the future price of the commodity being higher than the spot price. A common situation causing contango is an oversupply of the commodity in the market.

Impact of Harvey on Above Ground Storage Tanks

The toll of tropical storm Harvey on southeastern Texas continues to grow and be felt in various ways.  With this record breaking amount of rain for the region, structures of all sorts were tested.  This included above ground storage tanks in the oil industry.  Unfortunately, some of the API 650 tanks did not pass the test. Shell reported this week to regulators that the floating roof of one of its API 650 tanks in Deer Park partially sank due to the heavy rainfall.  Based on such issues, 100 pounds of benzene and 100 pounds of toluene were released.  Benzene is classified as a
