Nov 24 (Reuters) - Pipeline operator ONEOK ( OKE ) said

on Sunday it would buy the remaining shares of peer EnLink

Midstream ( ENLC ) for $4.3 billion in an all-stock deal,

boosting its presence in the Permian Basin amid increased

consolidation in the U.S. energy sector.

In August, ONEOK ( OKE )

acquired

a 43% controlling interest in Enlink, which has a solid

presence in the Permian basin, from Global Infrastructure

Partners for about $3.3 billion in cash.

ONEOK ( OKE ) said it will offer 0.1412 shares of its common

stock for each EnLink unit.

The deal values Enlink at about $7.6 billion, while the

stake purchase would be at a premium of about 5% to EnLink's

Friday close, according to Reuters calculations based on

EnLink's and ONEOK's ( OKE ) last close.

The U.S. pipeline and storage sector is seen as ripe for

deals following increased consolidation among oil and gas

producers, as well as hurdles in getting new energy

infrastructure approved and built.

Earlier in the month, another pipeline operator DT

Midstream

agreed

to acquire three natural gas transmission pipelines from

ONEOK ( OKE ) for $1.2 billion in cash, to boost its presence in the

Midwest market.
