Depth Model With S Wave Velocities DOWNHOLE ~SEilSMIC ISERVICES 0 Introduction DOWNHOLE SEISMIC SERVICES (DSS) conducted an offset vertical seismic profile, a zero offset vertical seismic profile and a walkaway vertical seismic profile for TEXACO U.S.A. in the Wolfbutton 32-7-8 well located in North Slope, Alaska. The wireline service for this survey was also provided by ATLAS WIRELINE. The survey was run on February 9 through 11, 1989. Field Observer's Logs for this survey are included as Enclosure 1 of this report. Ail measured depths are referenced to the Kelly Bushing (K.B.) elevation of 490 feet above sea level. The data for the survey consisted of 989 files (6 tapes) and was gathered between the depths of 2,000 feet and 9,145 feet (K.B.). At the time of the survey, the well had been drilled to a measured depth of 9,100 feet (K.B.) and cased to a measured depth of 2,400 feet (K.B.). There was no reported borehole deviation. OOWNHOLE; SEIISMIC ISERVICES Field Procedure DOWNHOLE SEISMIC SERVICES crew and eqUipment arrived at the well on February 8, 1989. All eqUipment was tested on site prior to the survey. DSS employed standard techniqUes for the VSP survey. The energy source used for the zero offset VSP was 2 vibrators located 616 feet N73W of the wellhead. The ground elevation at the source point location was 460 feet above sea level. The sweep freqUency was from 8 to 80 Hz. The sweep length was 8 seconds with a 4 second listening period. The data was correlated in the field. The energy source used for the offset VSP was 1 vibrator located 3,101 feet N88W of the wellhead. The ground elevation at the source point location was 460 feet aboVe sea level. The sweep freqUency was from 8 to 80 Hz. The sweep length was 8 seconds with a 4 second listening period. The data was correlated in the field. With the start of the VSP survey, the wireline depth sensor was zeroed-in at the Kelly Bushing (K.B.) elevation. The geophone tool was stopped five times going into the borehole to check all equipment performance and was eventually lowered to a depth of 9,100 feet K.B. Recording of the data commenced at that depth and proceeded as the geophone was raised to shallower depths, alternating recording between the zero offset and the offset shotpoints. At each downhole station, the wireline cable was stopped and the surface controlled, motor driven arm was activated to lock the geophone tool to the borehole wall. An average of 2 sweeps were taken at each depth level for the zero offset location and 4 sweeps at the offset location. Data was recorded for 4 seconds at a 2 msec. sampling rate (correlated). On completion of recording for a depth level, the wireline cable slack was removed, the locking arm retracted, and the tool moved to the next depth level. There were 75 levels recorded from the offset location. The shallowest depth level occupied on the up trip for the offset VSP was 4,050 feet (K.B.). There were 101 levels recorded from the offset location. The shallowest depth level occupied on the up trip for the zero offset VSP was 4,000 feet (K.B.). DOWNHOLE SEISMIC SERVICES A walkaway survey was also acquired using 12 source locations. The acquisition technique was similar to that described above for the offset VSP.

A display of the recorded walkaway YaP data is included in the back of this report. The downgoing waves were then flattened using the first arrival times. Each trace was cross-correlated with the first trace (selected as the reference trace) using a time window around the first arrival, and the first arrival times were subsequently shifted to ensure maximum coherency of the downgoing waves. A seven point median filter was applied to the total wavefield to pass the flattened downgoing waves. A display of the downgoing waves is included in the back of this report. The downgoing waves were then subtracted from the total wavefield to provide the upcoming waves. A three point median filter was then applied to the flattened upwaves in order to suppress noise. Individual deconvolution operators were designed using 300 msec. of the downgoing waveform for each depth level to shape the wavetrain to a spike~ These operators were then applied to the corresponding upcoming waves. The deconvolution results were filtered with a 15-40 Hz zero phase bandpass filter. A display of the upwaves after deconvolution is included in the back of this report. The walkaway survey was also processed using all 3 geophone components. Displays of the 3 raw geophone components is included in the back of the report. The first arrivals on the horizontal components were analyzed to determine the tool orientation at each level. The analysis consisted of computing hodograms based on the particle displacement between the two horizontal traces. At each depth level, the long axis of the ellipse was used to determine the rotation angle needed to align one of the horizontal components in the direction of the' source. After rotation, the horizontal component pointing in the direction of the source is term~the Radial component and the other is'called the Transv~gr~~4~~t. Displays are included in the back of the report. The next step was to determine the vertical ~i~l angle between the Radial and the yertical components, and vertical component to lie an the plane of the d~~%~~'~ls to recover the full downgoing response. The Vertical comp~e~ after this rotation is termed the Direct component and the Radial component which is 90 degrees from the Direct is called the Perpendicular component.

Ail shots per level were edited and summed to produce a stacked digital record arranged according to decreasing depth. First arrival times were picked in order to compute a time-depth curve. A digital display of the summed data for the zero offset VSP is included in the back of this report on Enclosure 2. Record quality was assigned according to the following scale: Good (G) Fair (F) Poor (P) Estimated (E) Not Useable (NU) - No extraneous disturbance, clear, sharp, high amplitude first break. - Inferior to G in one or more respects (mentioned above) but quite dependable to within +/- 1.5 to 2 msec. - Definitely inferior to F; a weak break or low signal-to-noise ratio, difficult to judge to within +/- 2 to 3 msec, but no doubt as to its authenticity. - Barely useable, perhaps a matter of doubt as to its authenticity, particularly at shallow levels where precursory energy is dominant. - First arrival not distinguishable, usually due to poor tool coupling or due to poor signal-to-noise ratio. The observed first arrival times were converted to vertical times and then referenced to the seismic datum as seen in the calculation sheets in Section 4. Final calculations, time-depth summary, and a detailed velocity listing, interpolated every 10 feet, are also included in Section 4. The final time/depth and average/ interval velocity curves are included as Figures 3 and 4 (Section 5). Vertical Seismic Profile Processing ZERO OFFSET VSP The summed data was corrected to compensate for amplitude decay due to spherical divergence using an exponential gain function of T**1.48 (where T is the recorded time). The downgoing waves were then flattened using the first arrival times. DOWNHOLE SEISMIC SERVICES Each trace was cross-correlated with the first trace (selected as the reference trace) using a time window around the first arrival, and the first arrival times were subsequently shifted to ensure maximum coherency of the downgoing waves. A nine point median filter was applied to the total wavefield to pass the flattened downgoing waves. A display of the flattened downgoing waves is included in the back of this report (Enclosure 2). The downgoing waves were then subtracted from the total wavefield to provide the upcoming waves. A five point median filter was then applied to the flattened upwaves in order to suppress noise. Individual deconvolution operators were designed using 575 msec. of the .downgoing waveform for each depth level to shape the wavetrain to a spike. These operators were then applied to the corresponding upcoming waves. The deconvolution results were filtered a time variant zero phase filter; 15-80 Hz at 1.0 seconds, 15-70 Hz at 1.2 seconds, 15-60 Hz at 1.4 seconds, 15-50 Hz at 1'.6 seconds and 15-50 Hz at 4.0 seconds. A three point median filter was than applied to the flattened upwaves. A display of the flattened upwaves after deconvolution is included in the back of this report on Enclosure 2. A corridor was defined close to the time of the first arrivals and a corridor stack was generated. Displays of the corridor stack, both polarities, are included on Enclosure 2. The entire upcoming wavefield was also stacked, and has been displayed on Enclosure 2. The corridor stack was phase rotated in +90 degree increments. A display has been included as Enclosure 3. Data from the zero offset VSP was then analyzed for converted shear waves. The first arrivals on the horizontal components were then analyzed to determine the tool orientation at each level. The analysis consisted of computing hodograms based on the particle displacement between the two horizontal traces. At each depth level, the long axis of the ellipse was used to determine the rotation angle needed to align one of the horizontal components in the direction of the source. After rotation, the horizontal component pointing in the direction of the source is termed the Radial component and the other is called the Transverse component. The next step was to determine the vertical arrival angle between the Radial and the Vertical components, and then rotate the vertical component to lie in the plane of the direct arrivals to recover the full downgoing response. The Vertical component after this rotation is termed the Direct component and the Radial component which is 90 degrees from the Direct is called the Perpendicular component. The Perpendicular component will contain upcoming P energy as well as downgoing S energy. An FK filter was applied to the Perpendicular component to pass downgoing shearwaves.

The observed first arrival times were converted to ~~l~L OOWN H O LE IS Elis M lC S E RVIC E Et vertical times and then referenced to the seismic datum as seen in the calculation sheets in Section 4. Interval shear velocities were calculated. These computations are in Section 4, beginning on Page 38. OFFSET VSP The summed data was corrected to compensate for amplitude decay due to spherical divergence using an exponential gain function of T**1.48 (where T is the recorded time). A display has been included on Enclosure 5. The downgoing waves were then flattened using the first arrival times. Each trace was cross-correlated with the first trace (selected as the reference trace) using a time window around the first arrival, and the first arrival times were subsequently shifted to ensure maximum coherency of the downgoing waves. A nine point median filter was applied to the total wavefield to pass the flattened downgoing waves. A display of the flattened downgoing waves is included in the back of this report (Enclosure 5). The downgoing waves were then subtracted from the total wavefield to provide the upcoming waves. A five point median filter was then applied to the flattened upwaves in order to suppress noise. Individual deconvolution operators were designed using 500 msec. of the downgoing waveform for each depth level to shape the wavetrain to a spike. These operators were then applied to the corresponding upcoming waves. The deconvolution results were filtered a 8-60 Hz zero phase bandpass filter. A three point median filter was then applied. A display of the upwaves after deconvolution is included in the back of this report on Enclosure 5. A depth model was generated using velocity information from a sonic log as well as seismic derived interval velocities from the zero offset VSP. The model and the upwaves from the offset VSP were input to the VSP-CDP Transformation program. After specifying the survey geometry, ray tracing was carried out on the input depth model to map the direct arrival times. These arrival times were then compared to the recorded first arrival times in order to update the velocities of the different layers in the model. ' After the model velocities had'been corrected, ray tracing was done to determine the arrival time curves from the reflecting interfaces defined in the model. These model-generated arrival time curves were compared to the arrival time curves exhibited by the recorded VSP data in order to establish the accuracy., of the structural model. In the case of a mismatch, the VSP data was transformed to the offset and depth (x,z) space to update the model. Starting with the shallowest velocity layer, this process ~llA CI OWN H 0 LE$ EEl.M lC IS E RVIC E S Interr~Jon~ was repeated for each reflecting horizon in the model. The drift between the model derived first arrival times and the recorded first break times was constantly monitored after each update to ensure the accuracy of the layer velocities. This procedure was repeated until an agreement was established between the model response and the input VSP data. Based on the final model, the transformation coordinates were used to map the VSP data into CDP offset and two-way time. A subsurface bin width of 50 feet was selected to vertically sum the traces that fell within the boundaries of the specified bins. Displays of the data after transformation in time are included as Enclosure 6. Displays of the data after transformation binned in depth are included as Enclosure 7.

A display has been included as Enclosure 7. Arrival times were picked on the Surface converted shear arrival and also on two arrivals which were caused by subsurface converting interfaces (One at approximately 4,400 feet below G.L., and one at approximately 7,100 feet below G.L.). This data was then input to the VSP-CDP Transformation program and velocity analysis was performed on the shear' wave arrivals using the same technique described above to map the P wave arrivals. Ray tracing for the shear wave velocity information was done at a datum of ground level (as opposed to sea level).

I found the diverter system with a manual butterfly valve at the annular preventer, and insufficient vent line to safely vent gas away from the rig substructure. I informed the Texaco rep of these deficiencies, and that I could not approve this system until a hydraulically-operated valve was installed at the annular preventer, and at least another 100' of I0 3/4" vent line was installed to clear the substructure. Sunday, January 15, 1989: I was called to the rig at 5:30 a.m. to '~inS~ect th~ive~~S-ystem, I found all deficiencies corrected, and tested and approved this system.

Tt~ree to five gallons of 10 weight oil was discharged. Upon notification, I wiped dow~ t:.I~e oil on tt~e loader w.Lth sorbents to prevent drips. I watc}ted the loader as it was movecl to a shop roughly 200 feet away, and then, wit)~ the help of two Nabors Drilling roustabouts, we used a sorbent roll (36" x 150') to chip and scrape the contaminated ice and sorbents into plastic disposal bags. We wiped down the tools and equipment and disposed of the bags at the well site. The site was clean by 7:00 a.m. I docume~te(! the spill before and after the photos. The Nabors roustabout an(] the Texaco hand helped a great deal to clean the site completely. Compliance by Nabors Dr-illing Company in notification and reaction was excellent.

Drill 5-10' of new hole below current T.D. 3. Circulate and condition mud (MW even in and out, properties consistent and acceptable). Pull up to the casing shoe. Close the annular preventer. 4. Establish formation leak off by pumping down the drill pipe as follows: a. Pump at a constant rate of one quarter (%) BPM using cement pumps. b. Record and plot cumulative volume pumped (% bbl increments) vs. drill pipe pressure until leak off is reached. Leak off is reached when the pressure increase is no longer constant for each % bbl pumped and will be seen as a deflection to the right on the plot. The actual leak off pressure is the last point on the straight line of the graph (last point of constant pressure increase / % bbl pumped). NOTE: Equip cementing unit with pressure gauge in suitable range for anticipated surface pressure ( generally, anticipated surface pressure plus 30%). · Upon reaching leak off, stop pumps and record pressure immediately and at one minute intervals for ten minutes or until decline levels off, whichever comes first. 6.
