A) Progress of Enhanced Recovery Project
During 2005, two additional production wells (NS05 and NS28) were brought on
line. The locations of these wells in addition to the other Northstar wells are
shown in Attachment 1. Production and injection statistics are summarized in
Attachment 2. Average oil production was 55,700 bopd and average gas
injection was 454.5 mmscfd.
During 2005, gas injection was just slightly less than reservoir voidage. At year
end, the reservoir had an overall voidage replacement ratio of 0.996.

These pressures are graphically represented in the next figure that is a plot of
pressure by well versus time.
These data indicate pressures dropped slightly during 2005 due to less than
balanced voidage make-up.
A complete listing of data from these surveys is shown in Attachment 4 on the
AOGCC Reservoir Pressure Report form.

8 D) Results and Analysis of Production and Injection Log surveys, tracer surveys, observation well surveys and any other special monitoring. No injection profiles and seven production profiles were obtained in 2005. In addition to the production log in NS24, a borax log was run 03/27/05 identifying a channel. The following table summarized these as well as previous profile results.

Unique chemical tracers were injected into the six Northstar gas injection wells (NS17, NS23, NS25, NS27, NS29 and NS31) on April 12, 2004. Gas samples are taken from each producer once every two weeks. Results to date are shown in the following plots.

E) Review of pool production allocation factors and issues over the prior
year
Theoretical production is calculated for each Northstar producing well on a daily
basis. A well’s theoretical production is calculated using average wellhead
flowing pressure and hours on production as follows:
ltheoreticaaof
n
whsi
whfproduced QQP
Phours =·-·124
Where:
hoursproduced = hours on line
Pwhf = average wellhead flowing pressure
Pwhsi = shut-in wellhead pressure
n = flow exponent
Qaof = absolute open flow of well with Pwhf = 0 psi
Qtheoretical = theoretical production
The input parameters (n, Qaof and Pwhsi ) for each well are determined from well
test data and systems analysis and are reviewed each time new test data
becomes available.
The actual total production for a day is divided by the summation of the
theoretical production from each well to calculate a daily allocation factor. This
allocation factor is then multiplied by each well’s theoretical production to
calculate allocated production.
Allocation factors for 2005 had an average value of 1.0928 and a median of
1.0932.

F) Review of Annual Plan of Operations and Development and Future
Development Plans
Northstar concluded 2005 with six injection wells, seventeen producing wells and
two Class I disposal wells on line. During 2005, the NS05 and NS28 producers
were brought on line.
This drilling activity is summarized in the following table.

Future Development Plans
We recognize the possibility that satellite hydrocarbon accumulations may exist
within expected drilling reach from the island. These targets will be the subject of
additional appraisal. Infill wells and or sidetracks to optimize recovery from the
Northstar pool are also possible.
As of March 2006, three additional infill development wells are planned and one
well is planned for a target outside the current Northstar Producing Area. Two of
the infill wells (NS14A & NS30) have been drilled to TD and are awaiting final
completion. Drilling is ongoing on a third well (NS34) and a fourth well (NS11) is
scheduled.

G) Status of Wells Shut-in for 365 days or More (20 AAC 25.115)
No Northstar wells were shut-in for 365 days or more during 2005.
