Attention: Mr. Don Go Benson -':': Subject: Core, Mud and Cuttings Yakutat No. 1.Well - ~ .- Wildcat - Yakutat, Alaskà Analysis ... Gentlemen: A mobile cornbination cuttings and core analysis laboratory was on location a.t the Yakutat No. 1 well during drilling operations from a depth of 595 feet to 9316 feet. IDe results of observations of gas concentrations in the drill cuttings and the drilling mud, the drilling rate, bit record, lithology of the cuttings, oil shows, mud da.ta, and oth~eµinent inforn1ation concerning the well, are presented on the Graphol~\ C!:lle results of all corr analysis performed on the well are presented on the attached Coregra8 Logging operations were commenced from under surface casing at a depth of 595 feet in an unconsolidated, varicolored, coarse to fine-grained con- glomerate, usually in a heavy clay matrix. With hardly an exception, down to 6000 feet, this clay matrix was absent from the washed sample, resulting in the conglomerate lithology as shown on the Grapholog, The first indication of a show was encountered at a depth of 1560 feet. At this point, there was a gas show in the cuttings with a high methane content. An investigation of the show indicated an unconsolidated sand conglornerate in a very heavy clay matrix with no stain or cut in the samples and no flu- orescence or gas in the mud. Continued drilling produced similar shows at 1600 feet, 1880 feet, and 2200 feet. At 3420 feet, 3620 feet, 3850 feet and 3900 feet, similar shows, but of a smaller magnitude, were also encountered. The nature of the shows and the lithologic properties of the formation would indicate the shows to be of no productive significance. .. fit' COI'~ ..,1"1 ¡.I'N' \'Fí' ,,') QAt! ''001<1. . .' ,. Colorado Oil &- Gas Corporation Yakutat No. 1 Well Page Two A gas show in the cuttings at 4100 feet was as sociated with a black to dark . brown bentonitic shale with moderate concentrations of shale gas. No sig- nificance was attached to this show. The first indications of a formation change were found at a depth of 6000 feet with the appearance of a soft gray shale. This changed to a dark brown to black carbonaceous shale at 6500 feet. Alternate dark carbonaceous shales and soft gray shales with unconsolidated, varicolored conglomerates, and unconsolidated, quartzitic sands continued through 8120 feet with an occasional influx of white to light gray, fine-grained, calcareous sandstone. An exploratory core was taken from 8410 to 8437 feet, as shown on the Grapholog. The recovered core consisted of a fine-grained sandstone, as shown on the Coregraph. Core analysis performed from 8432 to 8437 feet indicated good permeability and porosity, zero oil saturationsp and high water saturations. This interval was interpreted to be essentially water productive. At a depth of 8599 feet, side wall cores were taken of several of the above zones. Again, core analysis showed the samples to have good permeability and porosity, high water saturations, and to be essentially water productive. These results are shown at the base of the Coregraph in tabular form. An oil show was encountered at 8986 feet in a light gray, medium to coarse- grained sandstone. The samples had good fluorescence and a trace of cut. There was no fluorescence or gas in the mud. çor,e__N:9_'.2. was taken trom 9000 to 9010 feet resulting in the recovery of two' feet of siltstone a.nd shale. Core analysis indiçated low permeability, good porosity, zero oil saturations, and high water saturations. . This zone was interpreted to be essentially non- productive due to the low permeabilitYø but if any fluid is produced. it is be- lieved it will be water. Side wall cores taken in this zone also gave negative results. A similar zone was encountered at a depth of 9035 {eet. The samples ex- hibited a slight staining, good fluorescence, and a trace of cut. Core No.3 , ...._ ......A_ÃlL, _fi#t.~..::: was taken from 9064 to 9085 feet and core analysis again indicated. good per- meability and porosity with no oil saturations and high water saturations. GOtlflOtJ\\-t- ~lurl Colorado Oil & Gas Corporation Yakutat No. 1 Well Page Thr e e . Side wall cores of the zone also gave the same results, i. e., high water saturations. This zone is interpreted to .be essentially water productive. Drilling then continued in gray silty shale and siltstone to a depth of 9316 feet.

' COLORADO OIL AND GAS CORPORATION I RECOMMENDED DRILLING PROORAM FIELD OR AREA: Yakutat COUNTRY OR STATE: Alaska LEASE AND WELL NO.: 1 LœATION: Latitude 590 31' 34", Longitude 1390 40' 25" 12,650' S 540 E USLM#179 or 1260 true bearing PROJECTED T. D.: 7500 ELEVATION: 49 ft. G.t. CASING PROORAM: 18" Conductor pipe to approximately 80' cemented to surface. 13 3/8" Surface casing in 17" hole to approximately 550 ft., cemented into conductor pipe. - Drill out surface shoe with 12t" bit. Immediately under shoe reduce hole size to 8 3/4" to T.D. If intermediate protective casing is required, ream 8 3/4" hole to 12t" hole, run 9 5/8" casing to specified depth and cement as directed. To complete the well 5!" casing will be run and cemented as directed. On all casing Note: strings, centralizers, shoes and other equipment will be run as directed. It is realized this area may present crooked hole problems. However, every effort should be exerted to maintain the surface hole at less than one degree devia- tion and the intermediate and long holes so that there are no sudden changes in devia- tions. The intermediate hole should deviate no more than three degrees and every reasonable effort should be made to keep deviation of the long hole under five degrees. MUD PROGRAM: Drill conductor and surface hole with a bentonite mud as required to keep hole in condition and remove cuttings. Thereafter maintain mud as directed by Operator's Representative, .but always in such conditions as to maintain proper hole condition and properly remove cuttings from the well bore. DRILL PIPE TALLIES AND DEPTH ~WASUREMENTS: Tally out of hole before each log, drill stem test, core, and before running casing. If tally doesn't check with recorded depth, tally back in hole. Run straight hole sur- vey at least each trip, and at no greater interval than 500 ft. Page 2 DRILLING TIME AND WELL LOG: Mud logging truck instrument will maintain continuous drilling time log. Contractor will maintain a complete drilling log. The log forms shall be complete and signed by driller at end of each tour. The log shall be confidential and access to the log shall be allowed only to authorized persons. MUD LOGGING TRUCK: Mud logging truck will be placed on the hole before drilling out from under surface pipe. SAMPLES: Contractor will catch, process and dispose of samples' as directed by Opera- tor's representative in charge of operations. Contractor shall not allow any unauthorized person access to sanwles or sample data. CORING: Contractor shall core between such depths as directed by Operator and deliver all cores to Operator and shall not allow any unauthorized person access to cores or core data. A mud check shall be made prior to coming out to core. Mud will be conditioned as directed, but in every case water loss will be at 10 cc or less be- fore coming out to core. ELECTRICAL SURVEYS: Logs will be run when and as directed by Operator's representa- tive on location. A mud check shall be made prior to coming out of hole to log and mud put into condition as directed by Operator's representative on location. Logs will be run at approximately 1000 ft. intervals beginning at 3500 ft. In any event the hole sholùd be logged at least once each 30 days if as much as 100 ft. of hole has been drilled. FORMATION TESTING: Tests will be run when and as directed by Operator's representa- tive, and in each instance a mud check shall be made prior to coming out of hole to test. Mud shall be conditioned as directed by Qperator's repre- sentative prior to coming out of hole. The results of tests shall not be divulged to any unauthorized person. WELL CONTROL: Blmy-out preventers will be installed before drilling plug in surface casing. BOP will be opened and closed to insure proper working con- dition at beginning of each tower.
