Scott Petersen, Doug LaBelle II and Andrew McLardy finished two shots off the pace at 5-under-par 67.
Ogilvie, who captured the first event of the 2003 season at the Jacob's Creek Open in Australia, played the back side first at Fox Den Country Club and picked up three birdies over his first five holes. Ogilvie stumbled soon after with a bogey at the par-3 16th but countered with a birdie at the very next hole.
The 29-year-old made the turn at minus-3 and caught fire early on his inward half. Ogilvie tallied a birdie at the par-5 first and hit a 6-iron to 30 feet at the par-4 third for the first of three consecutive birdies en route to a share of the first-round lead.
'The putter was great today. I haven't been making long ones lately,' said Ogilvie. 'This is the kind of course you can't overpower. My distance control has been fantastic.'
Thatcher stood at 5-under after 11 holes and put together a strong finish to grab his share of the lead. He picked up a birdie at the par-4 15th but a bogey at the 16th hindered his progress momentarily.
Thatcher responded with a birdie at the par-4 17th after his 8-iron stopped 25 feet from the cup and closed his round with a 20-foot birdie at the par-5 18th.
'Still three days to go so I don't want to get overly excited,' said Thatcher. 'I had a good week last week so I have been in a good frame of mind. '
Like Thatcher, Ford had a solid start and rocketed up the leaderboard around the turn. He landed a sand-wedge inside three feet at the par-5 10th for the first of four consecutive birdies en route to a 65.
'It was a solid day,' said Ford. 'I've only played two events this year so I need to get something going. I need to get in tournaments each week and get used to this caliber of play again.'
Guy Boros, who won last week's Lake Erie Charity Classic, carded a 4-under 68 to finish three shots off the lead. Boros was joined by Kevin Pendley, Vaughn Taylor, Paul Claxton, Chris Tidland, John Elliott, Mike Brisky, Mike Donald, Chris Couch, Bob Heintz, Josh Broadaway and Craig Bowden in a tie for seventh.
Ryan Palmer, who won this year's Holden Clearwater Classic, was among a group of players at 2-under-par 70.
