Near term drilling includes two low risk exploratory wells at East Cameron 364 and a high risk, high potential deep shelf well at South Timbalier 138. To date in 2004, we have drilled 12 exploratory wells, with 9 successful, for a 75% success rate. Overall we have drilled 16 wells, with 12 successful, for a 75% success rate. Production Update Remington has recently commenced production from two new offshore production platforms located at West Cameron Block 398 and West Cameron Block 458. Both West Cameron 398 and 458 were scheduled for first production in the second quarter, however, significant delays were encountered during pipeline installations resulting in first production in July. The company has recently initiated production operations at Vermilion 241 and is currently installing the export pipeline at East Cameron 205. Both projects are expected at full producing rates by the end of July. Current developments that are scheduled to begin production during the third quarter include West Cameron Block 170 D-1St, West Cameron 383, West Cameron 458, and South Marsh Island 24 A-3. Additional volumes are scheduled for the fourth quarter from two wells at South Marsh Island 113 and the recent discovery at Vermilion 64. Production for the second quarter of 2004 averaged 104 million cubic feet of gas equivalents per day. The Company's current net daily production is approximately 120 million cubic feet of gas equivalents per day. Remington currently has six development projects underway that are scheduled to commence production over the next two quarters. Estimated production from these six developments in conjunction with our existing production base is projected to yield volumes between 22 and 23 billion cubic feet of gas equivalents for the second half of 2004. Estimates for the next two quarters of 2004 are 15% to 20% above the same two quarters in 2003, when we produced 19.2 billion cubic feet of gas equivalents. These volumes are consistent with our targeted 15% increase in production volumes for 2004 over 2003 levels. James A. Watt, Chairman and Chief Executive Officer, stated, "During the first half of 2004 our drilling operations were concentrated on development projects and lower risk exploration plays in an effort to achieve a targeted 15% growth in production for the year. In the second half of the year we will drill several higher potential, higher risk exploratory prospects."
