The 5 thru-tubing projects in the Lake Washington Area were mostly economically successful. Total costs were $855.1 million with 83.2% of the estimated costs. Cumulative oil production was 12,820 barrels with payout achieved in 34 days. Lessons learned included planning for weather delays when working in winter, that thru-tubing gravel packs can be effective sand control, and thru-tubing work can be done without coiled tubing to reduce costs.

4. Project Details – BDC #150
TTWO – Perf Addition; TT GPK Screen Hangoff
• Project Payout = 36 days
• Spent AFE = 87.8%
• 42 BOPD, 339 MCFPD, 524 BWPD, (current stabilized rate)
• Project Duration was 1 day over the AFE timeline estimate due to high winds and poor weather
conditions
• Np = 1,390 BO
• The first lesson learned from this project was to plan for weather contingency downtime days when
conducting workover operations in the fourth quarter of the year in the SELA area.
• The second lesson learned from this project was that a thru-tubing hang-off screen assembly
deployed in the end of tubing above the perfs was an effective sand control method based on the
production performance.

5. Project Details – BLD CM #15
TTRC – Natrural Completion: e-line TT preforator
• Project Payout = 3 days
• Spent AFE = 38.4%
• 219 BOPD, 67 MCFPD, 0 BWPD, (current stabilized rate)
• Project Duration was on schedule with the AFE timeline estimate
• Np = 9,400 BO
• The main lesson learned from this project was that we have an analog
that illustrates that we can produce a well from 6300’ as a natural
completion using controlled rate (small choke size ≈14/64”) for sustained
cumulative production value of over 60 producing days (Np = 9400 BO).

6. Project Details – CM #212
TTGPK RC – e-line/slickline & pump only operation
• The project will most likely never pay out since the well appears to be producing
from a slightly depleted water swept sand!
• Spent AFE = 129.2%
• 0 BOPD, 228 MCFPD, 20 BWPD, (current stabilized rate)
• Project Duration was 13 days over the AFE timeline estimate due to high winds and poor weather conditions and
Challenging well conditions.
• Np = 30 BO
• The team plans to further evaluate the reservoir performance of this project and to gain an understanding of why
this project failed to provide the production that was planned.
• The first lesson learned from this project was to plan for weather contingency downtime days when conducting
workover operations in the fourth quarter of the year in the SELA area.
• The second lesson learned from this project was that reservoir’s in the 3100’MD depth range are capable of
accepting a sand control treatment at 500 #/ft-perforation of sand being deployed in the formation without a
screen out in a slightly pressure depleted water swept reservoir.

7. Project Details – CM #212
TTGPK RC – project challenges
• High winds and poor weather conditions
• Gravel pack sand volume pumped was 25X job planned volume
• DW plug failed to set and function properly twice
• Umbrella plug setting issues requiring slickline fishing.

8. Project Details – CM #313
TTGPK RC – e-line/slickline & pump only operation
• Estimated Project Payout = 61 days
• Spent AFE = 60.1%
• 52 BOPD, 50 MCFPD, 9 BWPD (current stabilized rate)
• Project Duration was 2 days over the AFE timeline estimate due to high winds and poor weather
conditions
• Np = 1,000 BO
• The main lesson learned from this project was that the team was able to execute a thru-tubing
gravel-packed recompletion without using Coiled Tubing as a component of the recompletion
operation using only a pump spread and wireline spread to execute this job for 210 M$. This
operation represents about a 125 M$ savings as compared to the coiled tubing thru-tubing
gravel-packed method.
• The second lesson learned from this project was to plan for weather contingency downtime days
when conducting workover operations in the fourth quarter of the year in the SELA area.

9. Project Details – CM #339
TTRC – Natrural Completion: e-line TT preforator
• Estimated Project Payout = 30 days
• Spent AFE = 69.9%
• 44 BOPD, 100 MCFPD, 4 BWPD (current stabilized rate)
• Project Duration was 4 days over the AFE timeline estimate due to high winds and poor weather conditions and
tubing restrictions caused by scaling of tubulars.
• Np = 1,000 BO
• The first lesson learned from this project was to plan for additional slickline work days for the mitigation of scale on
the wall of the production tubing and completion hardware in the wellbore when working in the SELA area
• The second lesson learned from this project was that we have an analog that illustrates that we can produce a
well from 3000’ as a natural completion using a controlled rate for sustained cumulative production value of
over 60 producing days (Np = 1000 BO); furthermore the well is still producing without sand production issues.
• The third lesson learned from this project was to plan for weather contingency downtime days when conducting
workover operations in the fourth quarter of the year in the SELA area.
