Box 900 Dallas, Texas 75221 WELL: Gulf Oil Corp. No. 1 Colville Delta State, N. Slope Alaska AUTHORIZATION: Ulrich A. Franz ,! SAMPLE DESCRIPTION A total of forty-nine (49) cuttings samples and six core fragments were received. Forty-seven (47) of the samples were selected for analysis. Sample quality was generally good. SAMPLE PREPARATION This well was used to familiarize the Brown & Ruth Laboratories geologist with Mobil's specified handpicking procedure. Mobil's geologist furnished formation tops for ali of the wells and selected representative samples of the formations of interest. The samples were then picked in his presence to agree with the speci- fied tops. The sand intervals were excluded and not analyzed. Lithologic descriptions were, at Mobil's request, not carried out. POTENTIAL SOURCE UNITS The sediments represented by the samples between the surface and the well depth 2470' (formation tops unavailable) have very high organic carbon contents. The pyrolysis results indicate an immature section with no potential for significant hydrocarbon generation. Hot Zone (Pebble Shale) - Samples representing the Hot Zone Formation have ex- tremely high organic carbOn contents (most T.O.C. values exceed 3.0%) but be- cause the sediments.are very immature, it'is doubtful if the section is generating commercially significant quantities of oil or gas'. JURASSIC & TRIASSIC - Below the Neocomian Unconformity' there is a definite rise in the thermal alteration level. Although the sediments are still considered immature in the uppermost Kingak section, the. alteration gradient appears to reach the oil generating threshold near the base of the section. This has resulted · in a favorable oil source characterization for the organic rich Lower Kingak and Shublik Formations. Of the two, the Shublik has the greatest potential, and appears to be an excellent oil source. Although some of the Tertiary and Upper Cretaceous (Fishbone) samples exhi- bited extremely high organic carbon contents, the sediments are very immature and do not appear capable of generating significant quantities of oil or gas within this area.

Franz SAMPLE DESCRIPTION A'total of thirty-nine (39)' cuttings samples were received, and twenty-nine were Selected for analysis. Sample quality was 9enerally good, although in a number of cases there was insufficient material for analysis. SAMPLE PREPARATION Caved material was not a major problem in this well, although some was pre- sent in some of the samples. All samples were handpicked to conform with the formation tops submitted for the well. The sand intervals were excluded and not analyzed. Litho- logic descriptions were, at Mobii's request, not carried out. DATA EVALUATION The sediments represented by the samples from the well interval 2560-5520' (formation tops unavailable)are slightly above average in organic matter con- tent with T.o.C. values generally 1.0-1.4%. The pyrolysis data indicate an immature section with no potential for significant hydrocarbon generation. Fair to good source potential for gas and wet gas - condensate is indicated at base of Cretaceous, but the section is immature (based' on Truax values)- at well location. No source potential for oil or gas is indicated for Shublik Fm., Kavik Shale, or Kayak Shale at well location. !1 T T 1- "' ~';% BPd.)WN f3~ I{,tKFH I.AIi,OKAI~)I~,IL'4 IN(',. .

Franz SAMPLE DESCRIPTION A total of sixty-three (63) cuttings samples and eight (8) core fragments were received. Fifty-one of t.he samples were selected for analysis. Sample quality was generally good, although there was insufficient material for analysis in-some cases. SAMPLE PREPARATION Caved material was a major problem in this well, and it was' necessary to pick most of the samples. The picking was done according to the formation tops sub- mitted for the well. The sand intervals were excluded and not analyzed. As with the other wells, lithologic descriptions were not carried out. POTENTIAL SOURCE UNITS HOT zONE (PEBBLE SHALE) - The samples representing the Hot Zone Formation are extremely rich (T.O.C. values exceeding 4.0%), but are also immature. It is doubtful if such immature sediments can source significant quantities of either liquid or gaseous hydrocarbons and the zone is considered non-prospective within this area. JURASSIC. & TRIASSIC - The organic cOntent of the Jurassic and Triassic sedi- ments is high (I.23%- 2.35%), but the section appears to be immature. The pyrol- ysis results indicate that some hydrocarbons ar~e being generated, but it is doubt- ful if 'the quantities are commercially significant within this area. · Although some of the samples bet'ween the surface and 4750' (Tertiary tops un- available) exhibited an extremely high organic carbon content, the section is grossly immature and is not a source unit within'this area.

P.O. Box 900 Dallas, Texas 75221 Standard Oil of California No. 32-14 Simpson Lagoon, N. Slope, Alaska AUTHORIZATION: Ulrich A. Franz SAMPLE DESCRIPTION A total of ninety-seven (97) cuttings samples and six (6) core fragments were received. Seventy-four (74) of the samples were selected for analysis. Sample quality was generally fair tO good, although lost circulation material was present in some of the samples. SAMPLE PREPARATION Caved material was a major problem in this well, and it was necessary to pick most of the samples. The picking was done according to the formation tops sub- mitted for the well. The sand intervals were excluded and not analyzed. As with the other wells, iithologic descriptions were not carried out. POTENTIAL SOURCE UNITS HOT ZONE (PEBBLE SHALE) - Samples from the Hot Zone Formation exhibit very high organic carbon contents (T.O.C. values range from !.!0% to 3.50%), but un- fortunately the sedimentary section is extremely immature, it is therefore doubt-. ful if the sediments are generating commercially si. gnificant quantities of oil or gas. JURASSIC & TRIASSIC - The thermal conditions below the Neocomian Unconformity do appear higher, and the organic rich Jurassic (Kingak) and Upper Triassic (Shublik) do appear to have an oil source potential. Both the organic content and the thermal gradient show some increase with depth throughout this interval (Kingak to Shublik). Thus, the sediments with the maximum potential are the Lower Kingak and the Shublik Formations. Although some of the Tertiary and UPper Cretaceous (includes coaly Bluff and Fishbone) samples exhibited extremely high organic contents, the sediments are very immature and do not appear capable of generating significant quantities of oil or gas within this area.

Franz SAMPLE DESCRIPTION .A.total of twenty-two (22) cuttings samples and five (5) core fragments were received. All twenty-seven (27) samples were analyzed. Sample quality was generally good. SAMPLE PREPARATION Caved material was a major problem in this well, and it was necessary to pick most of the samples. The picking was done according to the formation tops submitted for the well. As with the other wells, lithologic descriptions were not carried out. POTENTIAL SOURCE UNITS HOT ZONE (PEBBLE SHALE) - Although the entire Cretaceous is definitely im- mature, the Hot Zone shale has an extremely high organic carbon content (3.42 - 4.10%). The pyrolysis results indicate that significant amounts of hydrocarbon has been generated within the Hot Zone, but it is uncertain if this immature section is generating commercial quantities of oil or gas.~ JURASSIC & TRIASSIC - The thermal maturation level appears significantly higher below the Neocomian Unconformity and this increase is reflected in the hydrocarbon source potential. The Jurassic Kingak Formation and Upper Triassic Shublik Formation appear to be generating significant quantities of oil. This is especially true of the Shublik Formation which appears to be an excellent source unit. ,. Although some of the Tertiary samples exhibit an extremely high organic carbon content, the section is grossly immature and is not a source unit within this area. 11 11 OPERATOR: Atlanti~: Richfield Company RUTH LABORAI'~.)I~IE,~, IN(:.

P.O. Box 900 Dallas, Texas 75221 IWELL: Union Oil Co. No. 1 KOOKPUK, N. Slope, Alaska AUTHORIZATION- Ulrich A. Franz SAMPLE DESCRIPTION A total of fifty-four (54) cuttings samples were received. Forty-five (45) of the samples were selected for analysis. Sample quality was generally good al- ~gh there was insufficient material in some cases. A few of the samples were also contaminated with lost circulation material. SAMPLE PREPARATION Caved material was a major problem in this well, and it was necessary to pick most of the samples. The picking was done according to the formation tops sub- mitred for the well. As with the other wells, lithologic descriptions were not carried out. POTENTIAL SOURCE UNITS HOT ZONE (PEBBLE SHALE) - The samples representing the Hot Zone Formation are extremely rich (T.O.C. values range from !.42% to 3.67%), but are extremely 'immature. It is doubtful if such immature sediments can source significant quan- 'titles of either oil or gaS, and the zone is considered non-prospective within this JURASSIC - Below the Neocomian Unconformity the thermal maturation level is significantly higher. The Kingak Shale is organically rich (T.O.C. values range · frt~a 1.32% to 3.11%). This organic richness, combined with the increased thermal maturity, results in a good oil source potential for the Kingak Shale. This is es- i~ecially true near the base of the Jurassic, where the alteration gradient is well ~ithin the oil window. This section of the Lower Kingak appears to be an excellent ell source. DEVONIAN - A Devonian argillite encountered at the base of the well has some potential as an oil source. The organic content is high (T.O C. values of 2.59% ~am:l ~1.0~1%), and the thermal maturation level is well within th~ oil window. . 1 OPERATOR: Union Oil Company BK()WN Fa? RUTH LABORATORIES. IN(;.

P.O. Box 900 Dallas, Texas 75221 Sinclair Oil & Gas Co. No. 1 Colville State, N. Slope, Alaska AUTHORIZATION' Ulrich A. Franz SAMPLE DESCRIPTION A total of twenty-four (24) cuttings samples and two (2) core chips were re- ceived. Ail twenty-six (26) samples were analyzed. Sample quality was fair, although a few of the samples were contaminated with lost circulation material. The upper eighteen (18) samples from 2560 - 6280 feet were just mudstone. SAMPLE PREPARATION Since the samples were mostly mudstone, and tops were not available until the Hot Zone at 5852', unpicked sample material was analyzed to this depth..The samples from 7890 - 9900 feet were handpicked to agree with the formation tops submitted for the well. As with other wells, lithologic descriptions were not carried out. POTENTIAL SOURCE UNITS HOT ZONE (PEBBLE SHALE) - Samples from the Hot Zone have very high or- ganic carbon contents (T.O.C. values range from 1.75% to 3.58%), but the samples are immature and the section is not considered to be a potential source unit within this area. Although some of the post-Hot Zone (Units of the Fishbone unavailable) sediments do exhibit greater than average organic carbon contents (T.O.C, values range from 0.89% to 1.42%) the samples are grossly immature and are not considered potential source units.

Franz SAMPLE DESCRIPTION A total of eleven (11) cuttings samples were received, and all eleven were analyzed. Sample quality was good. SAMPLE PREPARATION All of these samples had been previously handpicked by Mobil. Instructions were that the samples should be analyzed as received. No lithologic descrip- tions were.isarried out. DATA EVALUATION Because of the limited number of samples and the fact that they represented only -+ 900 feet of section, a plot of the data was not prepared for this well. The interval 4840-5740' (no formation tops were provided) is high in organic matter content with values ranging from 2-4%. The pyrolysis data indicate a thermally immature, gas prone section.
