I used to work in the industry, and can fill in a few details :)
15-20 years ago, Russia (and OPEC as a whole) really shot themselves in the foot by artificially keeping prices a bit too high for a bit too long. The high prices enabled/encouraged the development of technology (like fracking) that unlocked a whole lot of previously-unprofitable oil and gas. Once that genie escaped the bottle, there was no putting it back in. It takes years to develop (i.e. start production from) an oil field once you make the decision to build it out--drilling takes years, engineering all the facilities takes years, building takes a couple years, commissioning takes a year. Since not every project happens at the same time, the impact of that technology took a long time to percolate. But the impact is huge: the US became a net exporter of petroleum products, then a net exporter of crude oil. ExxonMobil's Golden Pass LNG terminal, originally slated to import LNG from the middle east (Qatar?), was redesigned to instead export LNG. And now they're building a second export terminal (CP2).
Aaaaanyway, OPEC has a whole lot less power over the O&G industry than they used to. They used to have a stranglehold (remember the embargo in the 70's?), but nowadays, everyone kinda shrugs and moves on when they cut production. For Russia, this will continue to deteriorate. They have little ability to develop their own oil reserves, and have historically partnered with the big multinational oil companies (ExxonMobil, Chevron, BP, etc), splitting the profits. From now on, however, those companies will be a lot less willing to partner with Russia--the risk calculations are a whole lot worse than they used to be.
One more thing about gas prices: the demand curve for gasoline in the US seems to be pretty flat--sure, people complain about high gas prices, but you don't see them doing much to curb their consumption. (Hey, look, we're back on a MMM topic!)
