TULAGEAK TEST WELL NO. 1

Tulageak Test Well No. 1 is located in the National Petroleum Reserve in Alaska (Figure 1). The well is located 1,140 feet from the west line and 3,338 feet from the south line of protracted Section 7, Township 21 North, Range 14 West, Umiat Meridian (Latitude: 71°11'21.62" North; Longitude:

155°44'00.82" West). Alaska State Plane Coordinates are: X = 295,272.76; Y = 6,287,738.37, Zone 5. Elevations are: ground level 10 feet and Kelly bushing 27 feet. Rig-up began on February 20, 1981, and the rig released on March 23, 1981.

The well was drilled to a total depth of 4,015 feet. The primary objective of the well was to test the sandstones in the basal portion of the "Pebble Shale" unit. Secondary objectives were the equivalents of the Jurassic Barrow sandstones and the Sag River Sandstone. The Argillite basement was reached at 3,964 feet.

Husky Oil NPR Operations, Inc. supervised and directed the drilling and support operations as prime contractor to the Department of the Interior, U. S. Geological Survey, Office of the National Petroleum Reserve in Alaska. Geological personnel were furnished by Tetra Tech, Inc.

Brinkerhoff Signal, Inc. was the drilling contractor; Brinkerhoff Rig 31, a National T -20, was used to drill the well.

DRILLING SUMMARY

Field operations at the Tulageak Test Well No. 1 location began on January 26, 1981, with the mobilization of construction crews and equipment required to build the drilling pad and an ice airstrip to accommodate C-130 Hercules aircraft. Construction work was completed on February 11.

The rig move from Walakpa Test Well No. 2 was accomplished with 34 Rolligon loads. Rig move-in operations began on February 16. Rig-up operations began on February 20, and were completed on February 26.

The well was spudded February 26, 1981, at 3:00p.m.

During rig-up, 20" conductor pipe was set at 105' and cemented with 475 sacks of 14.9 ppg Permafrost cement. A 12-1/4" hole was drilled below the 20" conductor pipe to 2730' and the hole conditioned for logs. This interval was drilled with a 3% calcium chloride mud system with a weight of

9.6 to 10.1 ppg. A calcium chloride mud was used to prevent damage to possible hydrocarbon reservoirs which are known to contain swelling clays in the Barrow area (determined from water susceptibility tests on cores from the South Barrow Wells Nos. 12 and 13). The presence of calcium chloride necessitated the running of a dual laterolog rather than a dual induction log. The following logs were run: DLL/GR/SP, FDC/CNL/GR/CAL, BHC-Sonic/GR/TTI, LSS/GR/TTI, and HDT-Dipmeter.

Nineteen sidewall cores were shot with seventeen recovered. Sixty-three joints of 9-5/8", S-95, 53.5 lb./ft. Buttress casing were run to 2720' and cemented with 1,500 sacks of Permafrost cement; slurry weight of returns was 14.6 ppg. The 9-5/8" casing was hung with a National casing hanger, and slips were set with full casing weight. The Hydril was tested to 1,500 psi; the blowout preventer and all other equipment were tested to 3,000 psi. A 13-5/8", 5,000 psi, SRRA arrangement blowout-preventer stack was installed. The casing was tested to 3,000 psi, and a formation leakoff test was run after drilling 10 feet of new hole. The formation was tested to 12.0 ppg equivalent with 9.6 ppg mud in the hole (360 psi surface pressure). There was no leakoff.

An 8-1/2" hole was drilled to 2940' with a mud weight of 9.9 ppg, and Core No. 1 was cut from 2940' to 2982' (38' recovered). Drilling operations resumed. Tight hole was encountered while tripping for a new bit at 3322'. The lower interval of the hole, 2970' to 3322', was tight and required three hours to ream. While tripping for a new bit at 3644', tight hole was encountered at 3376'. The stand was pulled too high in the derrick, and the blocks became wedged against the crown. The blocks were worked loose, and 590 feet of drilling line was cut as a safety precaution. Drilling of the 8-1/2" hole was resumed. Core No. 2 was cut from 3783' to 3816' (33' recovered). Drilling resumed to 3880' where circulation was lost. A lost-circulation material pill was spotted and circulation regained. Drilling resumed to 4005', and Core No. 3 was cut to 4015' (10' recovered).

The core following hole logs was reamed and were run:

prep a rations Temperature made for Survey, logging. The

DLL/SP/GR,

FDC/CNL/GR/CAL, BHC-Sonic/GR, HOT-Oipmeter. Twenty sidewall cores were attempted, and 18 were recovered. The top sidewall core was shot at 2730'; the bottom was shot at 3940'. A second temperature survey was run, and the hole was conditioned for testing.

Drill-Stem Test No. 1 was conducted in the open hole over the interval 3770' to 3825'. A 530' water cushion was used. Surface chokes were 1/4" and 1/8", and the bottom-hole choke was 3/4". All pressures listed below were recorded at 3811' and are the field data. The test is summarized as follows:

Initial Flow Period (30 minutes): Opened with weak blow, increasing to very strong blow in 15 minutes and continuing until shut-in; Initial Hydrostatic Pressure 1,993 psi; Bottom Hole Flowing Pressure from 279 psi when opened to 545 psi at shut-in.

Initial Shut-In (30 minutes): Initial Shut-In Pressure 1,841 psi.

Final Flow Period (120 minutes): Opened with strong decreasing to moderate in one minute, and to weak at shut-in;

Hole Flowing Pressure 545 psi at opening increasing to 684 shut-in.

blow, Bottom psi at

Final Shut-In (240 minutes): Final Shut-In Pressure 1,841 ps1; Final Hydrostatic Pressure 1,993 psi.

Recovery: 4. 59 barrels of slightly water-cut mud.

After running Drill-Stem Test No. 1, a decision was made to plug and abandon the well. Cement plugs were set from 3950' to 3700' with 96 sacks of cement and from 2800' to 2600' with 72 sacks of cement. Both plugs were of Class "G" cement containing 1% CFR-2. The pipe was pulled to 2000' and the mud was displaced with water; the water was then displaced with diesel oil. This was to allow future re-entry into the upper well bore by U. S. Geological Survey personnel to make temperature measurements.

The abandonment marker and head were set and installed; the rig was released March 23, 1981, at 12:00 noon.

Mud and rental equipment were shipped by Hercules C-130 aircraft to Camp Lonely. The rig was flown by Hercules C-130 aircraft to Fairbanks, Alaska, and trucked to Anchorage. This operation was completed on April 5, 1981. During and following the rig move, the rig camp was shipped to the South Barrow Pressure Reducing Station by truck where it was stacked out for future use in connection with the Barrow Gas Field.

Detailed drilling information, in the form of bit records, mud summary, time analysis, and casing and cementing reports, is included in the body of this report.

After the 1976 drilling season, casing requirements were reviewed and design of casing strings standardized. Every effort was made to minimize weight and grade changes for simplicity, cost effectiveness, and to reduce chances of error during handling and running operations. Casing sizes were selected to accommodate designs for wells from 2,000' to 20,000'.

Steel grade selection was the controlling factor on design with low hardness (Rockwell C24-28) steel being selected for Arctic application and possible H

S environment. Below is listed casing sizes and design criteria required by Husky:

(3) Special drift to 12.25".

Special drift to 8.50".

The following are additional requirements primarily to assure that the steel exhibits the metallurgical properties for Arctic applications and resistance to hydrogen embrittlement.

1. All pipe that is 13-3/8" OD and smaller to be quenched and tempered.

2. Run Charpy "V" notch tests on two random samples per 50 tons per heat. Minimum acceptance of 15 ft.-lb.@-50°F. Furnish test repor·ts with order.

3. Perform all testing normally required for API approved prpe.

4. Furnish test reports for ladle analysis, quantitative analysis, and all…
