It isn’t normal to have such frequent momentary outages. Usually, this is the result of an upstream breaker tripping. They automatically close back, usually in just a couple of seconds. Absent some trees falling on the line, a storm, or cars repeatedly hitting poles in your area, that shouldn’t be happening.
The partial outages are more interesting. That implies something at the distribution secondary (120/240 volt) level, or even in your own wiring.
Myself, I’d exercise every breaker in the box, including the main. Off, then on. Kind of ensures (hopefully) that the internal contacts are connecting solidly. I’d also record the times of when this happens, and then call OG&E. If you have a smart meter, they may already be seeing the issue, as long as the problem is on their side of the meter.
Do the short outages only take place during normal working hours, or later in the evening as well? Their work shouldn’t be causing this to happen, and especially not more than once when, say, they cut new wires into a new circuit. Most all their work should be done without affecting the customers.
One thing I forgot to mention - tree trimmers in the area. Some do very sloppy work, dropping a branch on live circuits occasionally, causing the station or line circuit breaker to trip, then restore automatically in a couple of seconds. They shouldn’t do this, but it can happen. Again, that would generally cut all your power for a few seconds, not just part of your power.
