Jack first worked at his family’s oil tool company when he was eleven
years old as a night watchman during the depression. He studied
engineering at Louisiana State University and enlisted in the Navy,
December 1941. He was commissioned as an officer and received his
aviator wings in July of ‘43. Jack was stationed in the Pacific at the
end of World War II.
Following the war, Jack returned as a salesman for the California based
Regan Forge and Engineering Company. The company produced numerous parts
and pieces of equipment to support the oil industry. In the 1950’s, Jack
Regan, then VP of sales for the company, observed early efforts to drill
and produce under the sea and recognized the limitations of current
technology. He foresaw the need for diverless subsea systems to permit
safe drilling in waters beyond the depth of conventional deep-sea
Jack and his team of skilled engineers along with sales and service
hands developed an impressive list of subsea drilling and completion
systems including the first drilling riser tensioning system, a
pressure-balanced ball joint connector, a diverless subsea Christmas
tree, drilling riser with integral kill and choke lines and an
under-the-ice subsea production tree. The diverless trees featured
acoustic release/reentry buoys, J-lay flowline connections and vertical
stingers, through-the-flowline downhole tools, remote guideline connect
and release tools, a through-flow subsea wellhead system and an
emergency production riser release connector. The Regan Diverter System,
which became a standard piece of equipment on floating drilling vessels
throughout the world.
Jack led the team that developed a total drilling and completion system
for 2,400-ft of water integrated with an ROV for primary completion and
emergency shutdown operations. As a result of his vision and
perseverance, his company, then named Regan Offshore International, was
recognized world wide as the leader in offshore enabling technology,
subsea drilling, completion, and production equipment.
Jack retired in 1982 and at that time he was President of Regan Offshore
International, and a Director of Hughes Tool Company.
