6-3-1 Process

Our keystone service offering — this process describes the weekly cadence of pre-testing communication during which we coordinate details, conduct research, and prepare protocols to ensure a successful testing experience.

Here's the rundown on our proven pre- to post-testing process that involves precise coordination and communication to ensure the best testing results.

From start to finish, we stay in constant communication. Learn what happens at the major milestone stages of 6 weeks, 3 weeks and 1 week prior to testing.
The 6-3-1 Process
6 Weeks Prior: Preparation
Alliance will email test week details to pertinent parties to request information that is unknown and address questions about permit research that has been completed. We hold ourselves accountable to every last detail, because every detail matters.

The following week we will prepare any testing notifications or protocols required by the regulatory agency(s) and continue our communication with pertinent parties.

Expect our background work and 1:1 communications to continue until mid-way through the process when we will begin sharing details on how testing will be conducted.
3 Weeks Prior: Verification
Successful stack testing takes a team approach. Getting the right information to the right people at the right time is our strength. Communicating what’s needed upfront saves time, improves quality and builds camaraderie, ensuring all parties feel connected and informed.

At this stage, the full plan begins to come together - from the big picture to the small details. No guesses, no assumptions. We validate the facts and communicate them to ensure everyone involved understands exactly what’s needed, because no two stack tests are the same.
1 Week Prior: Confirmation
One week prior to testing day, the Alliance Testing Technician will communicate directly with the customer site contact to confirm the meetup and kickoff schedule for the onsite testing. Additional emails with test week details will be sent to all pertinent parties to ensure there are no surprises. And, if there is a need to adjust to new information or emergent insights, we will adapt accordingly, keeping everyone informed along the way.

OGI (Optical Gas Imaging)

Alliance Technical Group offers industry-leading OGI services backed by a seasoned team, robust data systems, and a commitment to quality. Whether you operate upstream, midstream, or downstream, our nationwide team delivers high-performance leak detection where and when it matters most.

OGI is a flexible solution ideal for diverse industrial sectors and applications:

Upstream: well pads, offshore rigs, crude storage

Midstream: pipelines, gas terminals, compressor stations

Downstream: refineries, above-ground storage tanks

Other Sectors: gas utilities, biogas plants, landfills, mining, semiconductor manufacturing

OGI is also effective for detecting emissions from compressor rod packing systems, which are a common source of methane leaks in reciprocating engines. By visualizing and pinpointing these leaks in real time, operators can take corrective action before emissions exceed regulatory thresholds or impact equipment performance.
