HOUSTON, Aug 12 (Reuters) -

Exxon Mobil ( XOM ) issued a layoff notice to 59 employees

as part of its workforce reshuffle following its $60 billion

acquisition of Pioneer Natural Resources, according to a filing

with the Texas Workforce Commission.

Exxon said more than 1,500 Pioneer employees were offered

jobs as part of the merger. Pioneer had roughly 2,200 employees.

The layoff notifications include 39 workers from Las

Colinas, an area in the Dallas suburb of Irving, Texas, home to

Pioneer Natural Resources' former headquarters, according to the

filing. Exxon did not say how many of the 59 people would be

laid off and how many would take new jobs at the company.

Employees who received the warnings have either been offered

transition roles or declined offers to join Exxon, the company

said in a statement.

The job cut notifications filed this month also include

18 workers from Midland, within the Permian Basin, and two from

the Concho Valley, both located in West Texas, as per the

filing.

The merger combined Pioneer's more than 850,000 net

acres in the Midland Basin with Exxon's 570,000 net acres in the

Delaware and Midland Basins.
