This permit to drill does not exempt you from obtaining additional permits or approvals required by law from other governmental agencies, and does not authorize conducting drilling operations until all other required permits and approvals have been issued. In addition, the Commission reserves the right to withdraw the permit in the event it was erroneously issued. All dry ditch sample sets submitted to the Commission must be in no greater than 30' sample intervals from below the permafrost or from where samples are first caught and 10' sample intervals through target zones. Gamma ray, resistivity, neutron and density L WD logs must be acquired in the surface hole (from base of conductor to surface casing setting depth). Operations must be conducted in accordance with AS 31.05 and Title 20, Chapter 25 of the Alaska Administrative Code unless the Commission specifically authorizes a variance. Failure to comply with an applicable provision of AS 31.05, Title 20, Chapter 25 of the Alaska Administrative Code, or a Commission order, or the terms and conditions of this permit may result in the revocation or suspension of the permit. Please provide at least twenty-four (24) hours notice for a representative of the Commission to witness any required test.

A Seismic Analysis was performed for the Oberon #1 well and Pore Pressure / Fracture Gradient Curves derived. Again, no indications of abnormal pressure or weak formations were seen particularly at shallow depths. The mud weights planned for Oberon #1 are conservatively based on those used during drilling of the offsets. Prudent and precautionary drilling/tripping techniques will be emphasized while drilling this well with specific regards to potential shallow gas hazards. Annular Pumpina Operations: Incidental fluids developed from drilling operations will be hauled to the nearest permitted Class II disposal well. (Note that cement rinseate will not be injected down the dedicated disposal well but will be recycled or held for an open annulus.) The Oberon #1 surface/intermediate casing annulus will be filled with diesel after setting intermediate casing and prior to the drilling rig moving off of the well. If isolation is required per regulations over significant hydrocarbons, then sufficient cement volume will be pumped during the production cement job to cover those formations. PAl may request approval to inject or dispose of fluids in the, Oberon #1, 9-5/8" x 7" annulus at a later date. This request would be made after sufficient data is available to meet the requirements of AOGCC's 20 MC 25.080.

Logging 12-1/4" Surface Interval (0 - Surface Casing setting depth) LWD: GR / Res / Neu / Den 8-1/2" Production Interval (Surface Casing setting depth to TD) LWD: GR / Res / Neu / Den E-Line / Drill Pipe Conveyed: FMI/ Sonic / CMR / MDT / VSP Optional: Rotary Sidewall Cores Note: ConocoPhillips may decide to run Density-Neutron on E-Line. II. Coring None planned. III. Mudlogging Mudlogging service should be in operation from the base of the surface conductor casing to TD. Service most likely will include ROP on 5' intervals, lithology, total gas, sample collection, gas analysis of cuttings, gas chromatography, and H2S detection Thirty-foot (30') wet and dry samples will be collected from surface to casing point +/- 1,900' TVD-SS Thirty-foot (30') wet and dry samples will be collected from +/- 1,900' TVD-SS to well TD. Ten-foot (10') wet and dry samples, or continuous, collected across all shows and all target intervals. IV. Flow Testing Currently, Phillips plans to complete and test the Oberon #1 well. Flow testing and pressure bUild-up tests will be used to determine formation properties and estimate the commerciality of this exploratory well. A reservoir stimulation may be performed in the form of an acid or frac treatment. The flow period will be determined on-site in response to analysis of initial flow period, PBU and fluid properties. The well will be flowed to temporary surface production facilities consisting of gas separation and fluid storage tanks. Produced fluids will either be trucked to an existing production facility or reinjected into the formation following completion of the flow testing operations. Additional prospective intervals may be tested as described above or may be commingled with the previously tested intervals. If commingling is chosen, production logging will be performed during the flow test to determine the productivity of the individual zones. f6if.

Figures and attachments include a locator map and salinity presentation of a nearby well. The proposed well is located in section 9 of township 10-N, range 6-E. Nearest offset for this report is ARCO Colville River State #1. The area is also bounded to the NW by the Colville River Unit. A finding of "no Underground Sources of Drinking Water" (USDW) for the unit is documented in the Colville River Unit Injection Order 18A and supported by previous work. Of the offset wells outside of the CRU, only ARCO Colville River State #1 has sufficient porosity logs to calculate shallow salinities. Methods used have been documented in previous memos on this topic. A result plot is included as an attachment. The plot includes raw and reconstructed logs, Volume shale, effective porosity and TDS curves. The TDS curve in track 1 is highlighted blue in sands, defined as Vshale < 30%. The other wells have Gamma Ray and Resistivity only, in the shallow holes. An important pick for this issue is Base Permafrost. The introduction of reference 1 contains an excellent discussion on definitions and issues surrounding this pick. Permafrost is "defined by its (negative centigrade) temperature"1., as opposed to the "ice-bearing permafrost" more generally picked from non-thermal logs. Temperature logs from Alpine put permafrost at a depth of 1500+/- while recent temperature logs from Meltwater suggest 1350'. Simple interpolation suggests permafrost in the Oberon area to be 1400'. The ARCO Colville River State 1 well was the primary example used in permafrost discussions, 2 years ago {memos for the Nigliq (Feb. 26, 2001) and NPRA (March 2, 2001) areas}. Lowest "Ice-bearing" permafrost is picked at 1352'. Note from the plot, that all of the W. Sak sands are within the permafrost and unlikely to flow. The next potential sands are beyond the end of the plot and deeper than 5500'. Calculations indicate salinities will be in excess of 15 kppm below the permafrost. All of the reduced log programs for the other offset wells suggest the same conclusion. None indicate any sands below expected permafrost. The next deeper sands are in the Torok interval, below 5500', with salinities greater than 15 kppm. RECEIVED JAN 0 6 2003 Alaska Oil & Gas CtJns. CommissIon Anchorage 1.

Only one other well in this area has shallow porosity logs. ~ .." * H2S is not known to occur in this area within native-state reservoirs shallower than the Lisburne. SFD **Normal (9 ppg) pressure gradient expected to top of HRZ. Seismic velocity suggests pressure may build to 11 ppg at TD, but abnormal pressures have not been seen in the HRZ in any well within the area. SFD *** Gas-charged sands and hydrates below base of permafrost likely contributed to Cirque #1 blow-out (10 mi to SE). Thin, over-pressured gas- charged sands occurred at base of permafrost in Cirque #2. ConocoPhillips recognizes these hazards, mentions them in the Drilling Hazards Summary to be posted in rig floor doghouse, and lists appropriate mitigation strategies in the hazards summary. Well will be mud logged from base of conductor to TD, which will allow additional real-time monitoring of potential hazards.
