What were the effects of the oil crises on the Concorde ticket prices?
The Concorde started service only in 1976, so there never were actual pre-crisis prices. This makes your first question impossible to answer. Of course the airlines which ordered the Concorde had their plans how much to charge, but kept that a commercial secret.

When service started, the plane lost money. What happened next is an interesting lesson in economics. From A Pricing Lesson from the Concorde:


  The Concorde team decided to do some market research. They asked
  businessmen how much they thought a Concorde ticket cost. The answer,
  “Most of them didn’t know. It was their secretaries or travel
  companies doing the bookings. When they were asked to guess, because
  they were senior, very important people, they all guessed that the
  fare was higher. ” – explained Captain Jock Lowe, Concorde resource &amp;
  Planning Manager.
  
  This insight led to a new pricing strategy. Captain Lowe described “So
  very simply, we said, we’ll charge them what they think they are
  paying. And so we put the fares up”.  There was a discrepancy between
  what the company was charging and the value customers saw in the
  product.
  
  Concorde ticket prices were doubled to over $7,000,  one way, in
  today’s prices. As a result, Concorde was repositioned to provide a
  super-elite class for bankers, the rich, and the famous. Concorde
  became the place to be seen.


Generally, ticket prices were 1st class + 20%. So what affected ticket prices most was the all too human tendency to show off; the mechanism that makes luxury brands possible. Fuel became less significant.

Now let's look at the fuel cost. This table only starts in 1975 (but covers the full operational history of Concorde), and when I apply your factor of four, the pre-1973 price of jet fuel would had been 8 cent per Gallon. This means the nominal price has gone up by a factor of 50 when compared to the peak in 2008.



The Concorde typically needed 214 Gallons of fuel per passenger on the Paris - New York route (see my comment for evidence; using @mins much better source gives 236 Gallons), so that means fuel cost per ticket would look like the plot above, multiplied by 214 or 236. At the start of operations in 1976 that would had been about 70 USD per ticket, would had jumped to 200 USD per ticket at the start of 1981, would had dipped below 100 USD briefly in mid-1986 and again in 1998. The peak would had been above 800 USD in mid-2008 had the Concorde still been in operation at that time and would today be nearly 300 USD.
