Don O. Benson .~. Subject: Gentlemen: Core, Mud and Cuttings Analysis Yakutat Unit No. 3 Well _ State of Alaska A combination cuttings and core analysis unit was on location at the Yakutat Unit No. 3 well during drilling operations from 1~-12 to I0,848 feet. The results of observed gas concentrations in drill cuttings and drilling fluid, lithology of the cuttings, drilling rate and bit record, any oil shows and other information pertinent to this well are presented on the accompanying Grapholog. The results of the analysis, of side wall samples taken between 6334 and 7539 feet are presented on the Side '~Vall Core Analysis Data form. Logging operations were started under surface casing at lP. IZ feet in an unconsblidated conglomerate, quartz sand, and mudstone formation giving numerous shale gas shows in the drilling mud to a depth of 4200 feet. It is believed that none of these shows warranted investigation. Abundant fossil fragments were noted throughout this interval. Occa' sional stringers of a well-cemented, argillaceous, quartz sandstone were noted from 3700 to 4200 feet, and showed poor porosity. The first -significant formation change occurred at 4200 feet, and is a lignitic shale and siltstone. Formations from 4350 to I0, Z70 feet showed some porosity streaks, but no evidence of gas or oil concentra- tions in the cuttings or drilling fluid was noted. This zone is not be- lieved to be of any significance for commercial production. Colorado Oil and Gas Corporation yakutat Unit No. 3 Well Page Two Side wall cores Were taken in the interval, 6334 to 6373 feet. The sands Were unconsolidated, with a heavy clay matrix. Due to the soft, hentonitic clays, the permeability plugs-developed hairline fractures when heated to remove formation fluids. The samples as measured show some permeability, but it is due to the induced fractures from heating. Visual observations indic-ate the permeability to be very low. The 'erratic residual oil and water saturations, and higher than normal water saturations indicate this interval to be noncommerical. Side wall cores were taken also in the interval from 6629 to 6667 feet. These samples appeared to be of the same material as the interval from 6334 to 6373 feet. Due to erratic residual oil saturations and higher than normal water saturations, this interval is believed to be noncommercial. Samples analyzed from 6839 to 6843 feet also are believed to be noncommercial. Side vcall samples analyzed in the intervals, 7281 to 7385 and 7431 to 7539 feet, are not believed to be of any commercial significance due to erratic residual oil Saturations and higher than normal water sat- llrations. A conventional core was taken from 8476 to 8484 feet, and recovered a waxy shale with a few glauconitic sandstone inclusions. No analysis was made as visual inspection indicated no hydrocarbon shows and no permeability and porosity. · ConventionalCore No. 2 from 9027 to 9044 feet recovered I6 feet of a sandy, dense siltstone.with numerous calcite filled fractures, and occasional coarse-grained conglomerate inclusions. No oil or gas concentrations were measured. At 10, Z70 feet, a firm to hard, dense, oolitic limestone was encountered. From I0,398 to 10,400 feet, a fair methane gas con- centration was measured. Core No. 3 was taken from 10,398 to 10,4IZ feet and recovered two feet of a dense, hard limestone with calcite filled fractures. This core was poker-chipped and, due to the Colorado Oil and Gas Corporation Page Three Yakutat Unit No. 3 Well altered condition of the Core, no analysis was made at the request of the geologist. No fluorescence or cut was obtained fr. om these two feet, A good methane gas show was measured from 10,43Z to 10,448 feet. This was circulated out, and then cored from I0,438 to I0,448 feet. Recovery was six inches of dense, hard limestone with calcite filled fractures.. The core was poker-chipped and no analysis was made. No fluorescence or cut was obtained from samples. drill stem test of the interval, 10,364~o 10,448'feet, was evaluated a mi s run. Drill stem Test No. Z between I0,400 to i0,507 feet recovered'Z500 feet of water cushion, 920 feet of slightly gas-cutmud, 450 feet of drilling mud due to packer failure. Gas reading on the slightly gas-cut mud fluid gave reading of 500 units of methane. Drill stem Test No. 3 was made, before the hole was plugged back, between I0,290 and I0,494 feet, and recovered 720 feet of slightly gas- cut mUddy, salty water. Gas readings on the slightly gas-cut mud fluid gave a reading of 480 units of methane. Total depth of this well was reached at the depth of 10,848 feet, before the first hole was lost. Attempts were made to regain total depth with no success. No gas concentrations were measured during these at- tempts to regain total depth. A sidetrack was begun at a depth of 10,240 feet in an attempt to regain total depth. Cores Nos. 5, 6 and 7 were taken from I0,395 to 10,399 feet, 10,423 to 10, 4Z8 feet, and 10,428 to 10,438 feet, respectively. The hole was lost again at 10,554 feet. A whipstock was set at 9750 feet, and drilling commenced again to regain total 'depth. Cores Nos. 8 and 9 were taken'from 10, 367 to 10,369 feet, and from 10,446 to 10,456 fee~, respectively. The hole was lost again at I0, 7ZZ feet. A whipstock was set at 10,404 feet. Drilling was carried from 10,404 to 10,484 feet, at which depth hole was again lost. It was decided to discontinue drilling and hole was plugged back.
