Ann: Completion of Rosewood Plantation 21H No.1 U, page-13

re: Ann: Completion of Rosewood Plantation 21... Completion changes and Engineering
Following mechanical problems which were encountered in the completion of both the Deshotels 20H
and 13H wells and prevented them from realising their oil production potential, Pryme engaged an
experienced engineering team to evaluate the past drilling and completion performance of the wells
and determine a lower risk approach to the continuing development of the Turner Bayou project. As
a result, a simpler and well-proven approach to completion of future wells has been adopted. Thisincludes running a slotted or perforated liner in the horizontal section of the well, not cementing it in
place and avoiding the need to perforate the liner.
“These changes, as well as the application of improved drilling technology to keep the lateral portion
of the well within the target zone, should greatly increase oil recovery and reduce technical risk.” Said
Ryan Messer, Pryme’s Executive Director & COO.
