FIGURE 2 - NEW FIELD DISCOVERY IN AREA OF ADDITIONAL WELL CONTROL Discovery Well No. 4 proved production in reservoir from sub-sea 5000 to 5040. Proved area limited by structural position of low oil occurrence. Proved drilled area 40 acres, proved undrilled area 170. Total proved area on initial estimate 210 acres. Wells drilled in numerical sequence. Reservoir volume between fault and low proved oil occurrence considered proved. Reservoir volume between low proved oil and highest proved water is prospective. 39. Reservoir "A" with 30 feet of oil saturated reservoir. One oil completion, Well No. 2. Rate of dip on structure 225 feet per mile indicated by data on Well No. 1, dry hole. Proved drilled area 40 acres. Total proved area 90 acres on initial estimate including 50 acres proved undrilled. Completion of extension Well No. 3 in discovery Figure No. 3. Proved area of Reservoir "A" increased to 140 acres. Oil column is 35 feet, from sub-sea 4970 to 5005 as reservoir was found to be 5 feet thicker than in Well No. 2. Developed or proved drilled area is 80 acres. Total proved area 140 acres. 40. Completion of Well No. 4 in New Field Discovery Figure 3, confirms structural interpretation of Figure 3-A, and estend oil column in Reservoir "A" to sub-sea 5040. Proved drilled area 120 acres; total proved area 425 acres. Well No. 5 tested water in Reservoir "A" below sub-sea 5040 and proved the limits of the reservoir on the south side of the structure; and also, discovered oil accumulation in a new reservoir "B" from sub-sea 4070 to 85. New Pool discovery assigned 15 to 20 acres on initial estimate. Reservoir "B", not present in Wells Nos. 1, 2, 3, 41. FIGURE 4 CROSS-SECTION OF FIELD DISCOVERY (Wells Drilled in Numerical Sequence) New Field Discovery Well No. 1 tested gas in Reservoir "A" and oil in "C" and "D". Reservoir "B" not tested. Well completed as dual oil well in Reservoirs "C" and "D". Development Well No. 2 completed as an oil well in Reservoir "D". Reservoirs "B" and "C" not present. Productive area of Reservoir "C" initially considered proved between Well No. 1 and fault, revised downward on basis of new information. Development Well No. 3 extends the proved area and defines the limits of Reservoir "A". Tests oil in Reservoir "B". Completed as dual well in "C" and "D". Classified as new pool discovery in Reservoir "B". Reserves in Reservoirs "A" and "B" are classified as proved but undeveloped if they are not to be produced by Wells 1, 2, or 3. New Pool Discovery Well No. 4 drilled at location across fault found in Wells Nos. 1 and 2 is an exploratory well which tests gas in Reservoir "A" and oil in Reservoir "D". This well classified as new pool discovery by proving production in separate structural segment. -6000 -5000 -6000 |
