Oil prices were slightly higher today, posting a weekly decline after the Middle East risk premium came out of prices. Both benchmarks spiked more than $3 a barrel earlier in the session after explosions were heard in the Iranian city of Isfahan in what sources described as an Israeli attack. However, the gains were capped after Tehran played down the incident and said it did not plan to retaliate. “It was nothing but a big show, and so the markets deflated as quickly as they spiked,” said Tim Snyder, economist at Matador Economics. The oil and gas rig count rose by 2 to 619 this week. WTI traded up $.41 or .5% to lose at $83.14. Brent traded up $.18 or .21% to close at $87.29.
