Evaluation of Current & Emerging Emission Quantification Tools


PTAC is seeking a proposal to assess the current and emerging state of emission quantification tools, with specific focus on methane quantification.


Emissions quantification can be useful for better understanding source specific emission rates and fluctuation over time. Though the new methane requirements under Directive 060 do not necessitate quantification through measurement or metering, doing this can better inform vent or fugitive emission mitigation options. The most widely used tool historically is likely the Hi Flow Sampler, but the manufacturing and distribution of this device is now limited, so industry needs to understand what options are available for accurate and efficient emission quantification.

Project Scope

The scope of this project should focus on quantification tools that can be used at oil and gas sites for source specific quantification with outputs of emission rates; this can include both periodic and continuous measurement devices. The project should identify all current and emerging tools that can be used to quantify methane emissions, even if there is limited commercial viability at this time.


The project proposal should include a clear description on how each of the following deliverables will be completed:

  1. Quantification Tool Review Interim Summary Table – Collect data on all known emission quantification tools. Data of interest includes quantification method, brand, distributer, time required to take measurements, performance testing data on accuracy and precision, suitable applications, limitations of use, and other relevant data that might inform whether or not this could be used as a methane quantification tool for sources at oil and gas sites. Prepare a summary table on the findings of the review and include the findings as a section in the final report.
  2. Recommend the most viable quantification toolsBased on the finding in deliverable one, provide a recommendation on the top three to five (if available) most viable quantification tools for source specific measurements.
  3. Field Campaign Plan – Design a field campaign to expand the level of testing data available for each device to provide confidence in the devices ability to determine an emission rate. This campaign will result in defensible % accuracy ranges for given vent rates or vent rate buckets for all devices tested.
  4. Final Report – Prepare a report that summarizes the findings from the data review and the field campaign.

It is anticipated that there will be ongoing informal communication with the PTAC and the technical steering committee throughout the project. The proposal should include components for each stage with milestones, the project schedule, proposed costs and relevant expertise of the applicant’s proposed team.

Proposal Outline

The requested proposal should contain a very short description of the PTAC project and scope of work, CV or statement of qualifications and short excerpts of reports written by the applicant. The proposal document, which should be no more than 5 pages in length, addressing the following elements by the deadline stated below:

  • Scope of work
  • Deliverables
  • Budget and execution schedules
  • Personnel assigned to the project
  • Qualifications
  • Disclosure of co-funding agreements or partnerships

Proposals should be submitted online using the following form: Application Form

RFP Schedule

April 14, 2021          RFP issued
May 16, 2021           Deadline for submission to PTAC
June 1, 2021            Proposal selected by ARPC

Selection Process

PTAC has formed a Steering Committee for this project composed of industry stakeholders with relevant expertise. PTAC will facilitate Steering Committee proceedings but will not be a decision-maker.

All submitted proposals will be provided to the Steering Committee for review. The Steering Committee will determine if proposals meet the requirements herein and provide an overall ranking based on Contractor qualifications and on proposal quality. The Steering Committee will make the final decision.

Once a selection of the best proposal according to the Steering Committee has been made, all submission contacts will be notified by email of the regarding the outcome of their individual proposal. The project final report will be shared on the PTAC website upon completion of the project.

*NOTE: If you are a technology developer who is interested in participating in this project, please submit a letter of interest directly to Tannis Such at tsuch@ptac.org.
