Oil/gas production tank hatch monitoring – Eliminate methane emissions ​

Thief hatches are located on top of production tanks and are opened to manually measure levels. If not properly closed and latched they allow methane emissions to escape into the atmosphere. Tank hatch monitoring is a coming market. In Colorado, an operator was fined millions by the EPA for hydrocarbon emissions because their tank hatches were not properly closed to prevent leaking gases.​
Our tank hatch product, patent (US 9,764,893 B1) detects if the hatch is open, closed, or latched. Coupled with the SM3, it gives real time notification to the operator remotely. This application saves time and expense for field personnel to travel to and climb atop the tank to verify the hatch status.​ The design embeds a pressure sensor into a gasket and can be used on any type of equipment to determine if the correct pressure is being applied to the gasket to create a seal.

Hatch monitoring will typically be paired with production tank level monitoring at the wellsite. The SM3 is designed to handle both. The patented hatch sensor could be marketed as a single product for use with other telemetry solutions. Installation is simple and can be performed by a roustabout or pumper. Hatch monitoring will eliminate the greatest source of methane emissions at wellsites.
The design may be further developed to provide the operator notice of how much time the tank is venting even when the hatch is latched. This application would further reduce methane emissions.

Hatch monitoring can prevent the largest source of methane emissions​

Perhaps the simplest but most often overlooked solution to hydrocarbons escaping into the environment is to keep them contained in tanks with hatches closed and latched. Especially with production tanks in remote locations, the pumper must take time to climb to the top of the tanks (often in challenging weather) to ascertain if the hatches are open, closed, or latched. The Advantis tank hatch monitor provides a low-cost solution to save the pumper time and assure the company their tank hatches are secure.​
The best confirmation of this fact is provided by a study funded by the Environmental Defense Fund and other notable climate change proponents and summarized in a 2013 paper entitled “Measurements of methane emissions at natural gas production sites in the United States”:​
It is clear that even very motivated climate change researchers determined that climbing to the top of production tanks was too time consuming, despite the fact emissions from tanks are relatively large for many sites!​
Precise estimation of hydrocarbon emissions from production tanks, transport trucks, rail cars, and barges would be extremely difficult. However, due to the ease of installation and low cost of employing the Advantis hatch solution, the question should be: Why wouldn’t this be done to simply eliminate such emissions?​
An economic case may be made that the Advantis hatch solution is justified due to efficiency improvement for the pumper, plus proper containment and subsequent sale of incremental gas volumes that were prevented from escaping.
