PROPOSED T Y P E AND SEQUENCE OF ACTIVITIESAND APPROXIMATE LOCATIONS OF THE EXPLORATORY WELLSCham pi in Petroleum Company was awarded the South Timbalier Block 198 (OCS-C 7769)lease in the May 22, 1985. Central Gulf of Mexico Oil and Lease Offering (Sale 98).Champlin holds a 5Q-* interest in the block and Sun Exploration * Production Companyand Pogo Production Company each have 25** working interest.Seismic work has been performed over the block and results are addressed in the ShallowDrilling Hazards Assessment section of this Plan.Eight (8) exploratory wells are planned to test the geologic features in the block. Drillingsequence and proposed surface location of these exploratory wells are as follows:WELL DRILLINGSEQUENCESOUTH TIMBALIER BLOCK 198WELL NO.PROPOSEDSURFACE LOCATION12A6009 FWL, 2375 FSLB0809 FWL, 1560 FSL3C0099 FWL, 3999 FSL0D5999 FWL, 0299 FSL5E7699 FWL, 3099 FSL6F8999 FWL, 2969 FSL7G6599 FWL, 690 FSL8H3099 FWL, 599 FSLAll wells will be drilled as straight holes to a TVD of 16,599 feet. The required drillingtime, including testing and abandonment, is approximately 199 days per well.Onshore support operations should commence approximately seven (7) days prior todrilling operations. Pending approval of the applicable Federal and State Permits, ;t isanticipated that Well No. A will be spudded on or about February I , 1986, withexploratory operations on the block completed within the first quarter of 1988. probablyabout March I .

The data was obta. ed with a multi-sensor High-Resolution HazarAdArcheaological Survey over the entire block. The jurvey included a Suboottor i P v,299 cubic inch Hamco Water Gun, Side Scan Sonar, Precision Echosounuer and a MarineProton Magnetometer. Survey work commenced on August I, 1985 and was completed o.»August 4, 1985. Water depth in the block varies from 113 feet to 13? feet.Champlin's geologist has reviewed the Hazard Survey results.Conclusions concerningindividual well locations are sunmarized in the attached letter *» in,icate all proposedd r i l l sites are clear nf shallow hazards.Additionally, no archaeological features were seen in the data r-oen'.ed fur this block.
