Development drilling from the 8-slot platform should commence near the end of 1998 to develop production established by the OCS-G-16454 No.1 exploratory well drilled to 15,830 feet in 1996. In addition to the discovery well, a six-well development program is currently being filed with the MMS. Meridian's Capital Budget for 1998 exploration and development activities has been set at approximately $125,000,000 including new opportunities identified on properties to be acquired in conjunction with the recently announced merger with the onshore Louisiana business assets of Shell Oil Company. Since Meridian and Shell signed the Letter of Intent in December 1997 and the Definitive Agreement and Plan of Merger in March 1998, Shell has participated in three significant wells, one of which, the Stone Provost Cyr No. 7 at Weeks Island Field, has been completed for 2,000 BOPD (Shell W.I. 28 percent). The two other wells include the Gueydan Bourque No. 1 (Shell W.I. 50 percent) at West Gueydan field, currently drilling at 10,922 and the Stone Provost Cyr No. 8 (Shell W.I. 28 percent) currently drilling at 11,220 feet also at Weeks Island. The Company commented that it and Shell are pursuing an interim operating agreement whereby Meridian may assume operations immediately and through the close of the acquisition and merger, which is expected after a Meridian shareholder vote tentatively set for late in the second quarter. Management plans to discuss its current operations and aspects of the Shell Transaction during a conference call scheduled for 10:00 a.m. CDT on Tuesday April 7, 1998. -7- The Meridian Resource Corporation is an independent oil and natural gas company engaged in the exploration for and development of oil and natural gas properties utilizing 3-D seismic technology, primarily in south Louisiana, southeast Texas and offshore Gulf of Mexico.
