Oil Safe AR®-1030-WLF
Oil Safe AR®-1030-WLF is a safe yet functional replacement for traditionally inhibited hydrochloric acid treatments and MEA infused hydrochloric acid systems (also referred to as “modified acids for wireline”). Heartland Energy Group, Ltd introduced “patented synthetic acid systems” or “patented green acid” technologies in 2006. As the original pioneers and developers of synthetic acid systems our quality has remained consistent for almost 20 years in the industry. We are pleased to offer the same consistent backbone technology along with a few improvements which allow our 1030-WLF blend to meet and exceed the strict industry standards for corrosion rates and wireline integrity. Not only do we meet and exceed industry standards but have a proven supply chain and are not dependent on unstable commodities like MEA. Our pricing remains very stable and does not suffer large spikes due to oversees shipping challenges or plant shutdowns. Heartland Energy Group has multiple manufacturing locations in all the major plays and can deliver large volumes of our Oil Safe AR®-1030-WLF blend at a very competitive and economical price. Heartland’s 1030-WLF blend offers operators a great choice for acid spearhead work, stimulation and workover treatments. It allows operators the ability to safely spot spearhead acid with the perforating guns in the hole. Thus resulting in huge cost savings and large reductions in water use.
