U.S. crude oil inventories fell sharply during the week ending July 24, 2026. At the same time, refineries processed approximately 17.3 million barrels of crude per day and operated at 97.2% of available capacity.
For refinery engineers, reliability managers, and maintenance teams, the bigger story is not simply that crude stocks declined. It is what the operating data reveal: U.S. refineries were running near full capacity, leaving less room for unexpected shutdowns, slow diagnostics, or unnecessary equipment teardown.
When throughput is high, inspection readiness becomes an operational priority.
Teams need reliable ways to investigate internal conditions, document visible problems, and determine whether equipment can continue operating or requires further nondestructive testing, maintenance, or repair.
According to The Wall Street Journal’s report on U.S. crude oil inventories, commercial crude inventories, excluding the Strategic Petroleum Reserve, fell by 7.2 million barrels during the week ending July 24.
Inventories reached approximately 404.5 million barrels, around 7% below the five-year average for that time of year. Analysts surveyed by the Journal had expected a much smaller decline of roughly 600,000 barrels.
Several factors contributed to the larger draw:
The U.S. Energy Information Administration Weekly Petroleum Status Report provides the official data on U.S. crude oil stockpiles, refinery inputs, imports, exports, and production.
A single weekly decline does not mean the United States is running out of crude oil. Inventories regularly move in response to refinery demand, production, trade, transportation, and storage activity.
For refinery teams, the utilization figure provides the more practical takeaway.
U.S. refineries processed approximately 17.3 million barrels of crude oil per day during the reporting week, about 271,000 barrels per day more than the previous week.
Refinery capacity utilization reached 97.2%.
That figure is a national average, not the operating rate of every individual facility. Even so, it shows that a substantial share of available U.S. refining capacity was in service.
High refinery utilization does not automatically cause corrosion, cracking, or equipment failure. The EIA data do not establish that connection.
The operational issue is simpler: when refineries are processing high volumes, unexpected downtime may be harder to absorb. Production schedules are tighter, maintenance windows become more valuable, and teams may need to diagnose equipment concerns quickly.
This is where refinery reliability and inspection readiness matter.
A refinery maintenance program is built around equipment history, known damage mechanisms, process conditions, previous inspection findings, and planned maintenance intervals. But even a strong program can be tested when throughput is high and an unexpected equipment concern appears.
When an abnormal reading, efficiency loss, blockage, leak indication, or mechanical issue develops, maintenance teams need answers quickly:
This is where inspection preparedness makes a measurable difference.
A team with the correct borescope, probe configuration, access information, and inspection procedure can begin gathering visual evidence quickly. Images and video can help locate the issue, support communication with engineering, and determine whether additional testing or teardown is necessary.
An unprepared team may lose valuable time finding equipment, confirming access dimensions, sourcing the correct probe, or dismantling more of the asset than the investigation requires.
A borescope will not answer every mechanical integrity question. It can, however, reduce uncertainty at the beginning of the diagnostic process where faster, better-informed decisions are needed.
Refineries contain piping, heat exchangers, valves, pumps, vessels, and internal assemblies that cannot always be examined through direct line of sight.
Where suitable access is available, an industrial borescope or videoscope can help maintenance teams view and document visible internal conditions.
Potential findings may include:
An articulating videoscope allows technicians to steer the camera around bends and internal structures, making it easier to examine areas that would otherwise remain out of sight.
This can be useful for refinery piping inspection, heat exchanger tube inspection, valve internal inspection, and targeted examination of other process equipment.
Complete disassembly is sometimes necessary. It should not always be the first diagnostic step.
A borescope inspection may help answer several preliminary questions:
This information can make maintenance work more targeted and help teams use limited maintenance windows more effectively.
Remote visual inspection does not eliminate downtime. It can reduce uncertainty before more time and labor are committed.
A refinery inspection becomes more useful when images and video are connected to a specific asset, access point, date, and inspection location.
Documented findings can be shared with maintenance, reliability, engineering, operations, or outside specialists, even when those individuals are not physically present.
Consistent records also make it easier to compare visible conditions during future inspections.
Useful inspection records may include:
The Occupational Safety and Health Administration’s Process Safety Management standard requires covered facilities to maintain procedures for the ongoing integrity of process equipment and document inspection and testing activities.
A remote visual inspection system shows what is visibly present inside an accessible area.
It does not answer every mechanical integrity question.
A standard borescope generally cannot determine exact remaining wall thickness, measure subsurface cracking, calculate remaining component strength, or establish fitness for service.
Those questions may require methods such as:
For example, the API 570 Piping Inspector program addresses the broader inspection, maintenance, repair, and alteration of in-service metallic piping systems.
The strongest refinery inspection programs match the tool to the question.
Remote visual inspection is most effective when used alongside the appropriate NDT and engineering methods.
The latest refinery utilization data provide a timely reason to review internal inspection capability.
Teams should know the size of common inspection openings, the distance to the target area, and whether the application requires a straight-view, side-view, or articulating probe.
Different assets may also require different probe diameters or working lengths.
Before inserting a videoscope, confirm:
A general-purpose videoscope should never be assumed suitable for every refinery environment.
Use consistent file names, equipment identifiers, camera orientation, and inspection notes.
Capture both wider views and close-up images when practical. Separate visual observations from conclusions requiring engineering review.
Inspectors should know what happens when they identify possible cracking, significant corrosion, heavy deposits, deformation, leakage evidence, or another uncertain condition.
The next step may include expanded inspection, specialist NDT, engineering review, repair planning, or immediate operational action.
SPI Borescopes provides industrial remote visual inspection equipment for difficult-to-access internal areas.
The Recon Pro articulating videoscope supports interchangeable probe assemblies, multiple probe diameters, image and video capture, and different viewing configurations.
Its interchangeable probe system allows maintenance teams to use one base unit with multiple probe options rather than purchasing a separate complete videoscope for every access requirement.
That flexibility can be valuable in refinery environments where piping, valves, tubes, and internal components have different opening sizes and inspection distances.
SPI also offers a warranty, repair, and product swap program designed to reduce the time inspection teams are without a working probe or videoscope.
Every refinery application should be reviewed individually. Temperature, pressure, chemical exposure, atmosphere, access conditions, and required inspection data must all be considered before selecting equipment.
Teams evaluating remote visual inspection options can use SPI’s free mail-out demonstration program to test probe access, articulation, image quality, and handling in their own inspection environment.
The 7.2-million-barrel decline in U.S. crude oil inventories attracted attention across the energy market.
For refinery engineers and maintenance teams, the operating figures behind the headline matter just as much.
U.S. refineries processed approximately 17.3 million barrels of crude per day and operated at 97.2% of capacity during the week ending July 24.
When utilization is high, teams need to investigate internal equipment conditions quickly, document what they find, and decide what happens next.
Remote visual inspection cannot measure every defect or replace a complete mechanical integrity program, but it helps teams see otherwise inaccessible areas, locate visible problems, and determine whether teardown or additional NDT is required.
The goal is not to use a borescope for every inspection.
The goal is to have the right tool ready when the answer is out of sight.
U.S. commercial crude oil inventories fell by 7.2 million barrels during the week ending July 24, while refineries operated at 97.2% of available capacity.
The data do not show that high utilization caused equipment damage. They do highlight why refinery reliability, efficient diagnostics, and inspection readiness matter when facilities are processing high volumes.
Borescopes can help refinery maintenance teams examine suitable internal areas, document visible corrosion, deposits, debris, obstructions, and mechanical conditions, and determine whether additional NDT or disassembly is required.
SPI Borescopes offers articulating remote visual inspection systems with interchangeable probe options for different access requirements. Refinery teams can review the Recon Pro or request a free mail-out demo to evaluate probe access, articulation, and image quality in their own environment.
