Emissions Advisory Services


Individualized solutions to

emissions management 

As the move from methane estimation to measurement becomes enforced, there are many detection and quantification technologies available, including default (OGI Method 21) and alternative approaches that operate on varying scales (UAV, mobile, aerial, satellite, fixed sensors, etc).

At Arolytics, our perspective is a holistic one that embraces ALL emissions measurement technologies. Our team has experience working with all measurement types, from satellite to OGI. We realize the optimized measurement program will differ for every operator, depending on factors like cost tolerance and production type. Taking a neutral stance enables us to design custom emissions monitoring programs that optimally integrate various technologies in a cost effective and regulation-compliant manner.




Arolytics has developed a Methane Simulation Model to  validate the use of innovative alternative leak detection technologies, giving you all the information you need to plan an alternative fugitive emissions management program (alt-FEMP), demonstrate equivalency to the regulator as required, and reduce compliance costs.

Developed in consultation with relevant energy regulators, we model various theoretical programs to understand the effectiveness and cost of using different combinations of measurement technologies at your development, ensuring we create an optimized program that works for you. 

Using our model, we are working with some of Canada’s largest oil and gas producers to design custom alt-FEMPs.

Modelling can be used to estimate:

  • Emissions reductions from various leak detection and repair (LDAR) programs and combinations of technologies
  • Costs of various LDAR programs
  • Time required to conduct LDAR programs
  • Estimated number of leaks detected and repairs required
  • Additional implications of using various technologies

Experiment with various measurement technologies, frequencies, and repair timelines, to find an alt-FEMP that works for you.



Informed by emissions simulation modelling results, Arolytics designs customized, cost-effective, and compliant FEMPS and alt-FEMPs.

In addition, we offer FEMP and altFEMP application development as a service. 

Helping you make technical decisions, remove risk, build for performance, and achieve cost savings, Arolytics covers all bases from the initial measurement program design, logistics, implementation, data analysis, modelling, proof of emissions reduction equivalency, preparation of regulatory applications, and reporting support.


You’ve collected all of your emission measurements. Now what? We analyze trends, statistics, and patterns, enabling you to make informed management decisions, get more value out of the data you’re collecting, and track company progress towards emission reduction targets. 

Progress tracking also includes assessing the performance of your company’s FEMP over time, ensuring program performance is meeting expectations. 

FAQ: Leak Detection With ‘Alternative’ Technologies

⇒ What is it?

Commencing in 2020, Canadian oil and gas producers are required to implement methane Leak Detection and Repair (LDAR) programs 1-3 times annually across a range of assets. Default measurement approaches involve effective, but labor-intensive, methods such as EPA Method 21 and Optical Gas Imaging (OGI). However, the regulations also allow producers to design their own Alternative LDAR programs that incorporate innovative technologies. If approved, these alternative programs could incorporate a triage system, relying first on inexpensive regional-scale methane screening tools (sensors, vehicle-based, satellite), followed by smaller-scale EPA Method 21/OGI only where required.

⇒ What are the advantages of Alternative LDAR?
If used correctly, many alternative technologies have broader coverage, making them both cost effective, and time efficient. Alternative LDAR enables companies to deploy innovative monitoring technologies that will save on measurement costs, increase measurement data quality, and decrease the time it takes to get results.
⇒ How can I propose and run an Alternative LDAR program?
Prior to the implementation of a compliant Alternative LDAR program, an application must be submitted to the appropriate regulatory body (federal or provincial). The application must prove that the suggested Alternative LDAR program will result in at least the same emission reductions as the default, regulatory program (OGI and EPA Method 21). We can help make this process seamless, performing the modelling or field tests required to prove emission reduction equivalence.
⇒How much methane can be mitigated from my operations, and at what cost?
 We model various theoretical measurement programs to understand the effectiveness and price of using different combinations of measurement tools at your development. Modelling allows us to determine if and where alternative measurement approaches are a good choice for your situation, how much the program will cost to execute, and what magnitude of methane emissions can be mitigated.
⇒Where do I start?
Many producers lack experience with alternative methane detection technologies, as well as the modelling that is required to demonstrate emissions reduction equivalence. We can help kickstart benchmarking programs, piece together the puzzle of what measurement technologies to use where and when, prepare regulatory Alternative LDAR submissions, help oversee the program, and provide summary analytics that evoke action.
