UP Exploration (Alaska) has been working on ways to produce viscous oil, also reCen'cd to as heavy oil, at Milne Point since the 1990s and now also has viscous oil under devclop- . men! in the weslem Prudhoe L :1 /2 A't.Jÿ satellites. . '. ., Multi-lateral horizont.al S E R I E S wells have solved the drilling side of the viscous equation, but problems remain on the production side, members of BP Exploration (Alaska)'s drilling team told Petroleum News in late September. Viscous oil accumulations lie closer to the surlllce and are colder, less mobile and have poorer reservoir quality than conventional crude oil, said Mik Triolo, Greater Pl1ldhoe Bay operations drilling engineer. Triolo worked the Schrader Bluffviscous accumu- lation at Milne Point before moving over to Orion, working on the carly multi-lateral and horizontal well designs in late 1999, early 2000. "And we've progres- sively evolved that technology ever since," he said. That work is continuing at Orion, a Pl1ldhoe Bay western satellite viscous· oil accumulation. Multi-lat- eral wells, well bores with multiple horizontal laterals into shallow sands containing viscous oil, make wells productive enough to bc economic. First tri-Iateral in 2003 In 2003, DP drilled the first tri-Iateral multi-lateral well on the slope, and this year, the company set a world record with a quad-lateral well. "Horizontal multi-lateral wells have been the key to unlocking those (viscous) reserves... predominate- ly through efficient geo-stccring within the segregated sands... Rather than undulating through them," Triolo About the series Editor S Note: Members of BP Exploration (Alaska) s drilling group sat down with Petroleum News Sept. 28 to talk about the company's development drilling program, recent drilling records and about the technology that is driving the company s North Slope development drilling. Part 1 of this story, printed ill the Oct. 10 issue of Petroleum News, included all overview of the company s North Slope drilling activity and an update on its coiled tubing drilling pro- gram. Part 2, which appeared in the Oct. 24 issue, described multi-lateral drilling at Milne Point, and wel/maintenance work. said, "we actually stick dedicated laterals into each one of the sand intervals." In addition to better ability to steer through the fonnations, drilling also helps vis- cous oil deveJopment with "good well design," he said. A cl1lcial part of the well is where the laterals branch fi'OIll the main well bore, and Br has also been trying different junction designs, the connection between the main well bore and the lateral. At Milne Point BP detemlined "that the level three, the TAML level three junction, was the junction of choice.. .," Triolo said. TAML stands for Technical Advancement of Multilaterals, an organization set up to regulate "the different levels of multilateral junction equipment such that everything is standardized," he said. "So if Baker comes out with a level-thrce junc- tion, the criteria that are set up to distinguish between a level-three and a level-four, are the same as for Halliburton.. ." The TAML levels, said Mark Johnson, BP senior coiled tubing drilling engineer, "refer to the re-entty capability of the junction and how well it seals or iso- lates at that jWlction." Re-entty capability and the seal see BP page 10 ~ -<' 10 ---...- ,~. continued from page 9 ;.c :.c: ~ ~ z o . provided are the two primary things a junc- 5 tion does, he said. ~ x Triolo said BP detennined "that we did ~ not need isolation at the junction - what we ~ needed was access to the lateral, so the level- ~ three junctions became the method of ~ ::;) choice." 8 BP First level-three, quad-lateral well in world BP took its experience at Milne Point to Orion, a western Prudhoe Bay satellite, and this year "we drilled the first level-three quad-lateral multi-lateral well in the world," Triolo said. (The accompanying graphic illustrates such a quad-lateral multi-lateral well.) BP's initial experience with multi-lateral wells was that complicated wells were . expensIve for the wells group to maintain: "We didn't really have cost-et1cctive ways to work on the wells or impact the flow streams of the wells later in life, so we went back to the drawing board and came up with some criteria that we wanted to see achieved in our well designs, and then worked with our v.endors to come up with a solution to those problems." The current system, he said, was "proved up in Milne Point" and the junction design was modified at Orion "to add more e!1ì- ciel1cy to the full life-cycle cost of the well," Triolo said. Well work can now be done through the tubing, with a coiled tubing unit, without the need for a workover rig. The total footage in the quad-lateral well, Prudhoe Bay unit L-20 I, was almost 35,000 feet, with "almost 28,000 ieet of horizontal footage within these thin bedded sands," more than five miles of horizontal footage in OIlC well, Triolo said. There were cleanup issues with the well, and UP didn't realize full flow potential, but the well had a productivity index of 40 (a measure of bands per pound of square inch drawdown), compared to most wells on the slope somewhere ill the 20-range. "If we could have opened it up lull bore, we probably would have been somewhat tubing limited," he said. Facility limited Right now the well is facility limited, Triolo said. Daren l3eaudo, I3P's director of public affairs, said one of the things BP worked on during the summer production G~ÆY1ht6rAf" vlscoua OIL QUAD ML COMPLETION - "JF 11 J R) , Ht J ill ~ ~1_.~_. >- . . .. .... .. ~-- ~04·- D 1.ffC¿TROLEUM NEWS. WEEKOFOcrOBER31,2004 ~ ,";~~~¥;!-:>i~=}~~;_~~~~ shutdown at Prudhoe Bay was cleaning sand out of tanks in Gathering Center 2. "One of the constraints that we've had is managing all of this sand," he said. "This is a viscous oil production issue, nol a well-rate issue," l3eaudo said, and the issue is the sand produced with the viscous oil. To really produce viscous to the maxi- mum, BP will either have to add facilities to handle sand that comes to the surface or find a way, such as screens, to kcep the sand in the rcselvoir. Not only does sand accumulate in pro- duction facilities, said Andy Kirk, BP's Alaska drilling and wells pcrfOlmancc con- sultant, but it also causes problems in pipelines because it is cOITosive - another reason to keep it in the IOllllation. And if a multi-lateral well has to be shut in and the oil stops flowing, Kirk said, the sand can layout along the horizontal portion ofthe well, creating dunes which plug up the well, making it difficult to re-establish pro- duction when the wcll is brought back online. Opportunity huge The oPP0l1unity for viscous' is huge: '"<4.- ~,""__ :;;~~Ñx;~~;]J=~:'"t::!¢~e some I.6 billion barrels recoverable with current technology, said Gary Christman, BP's Alaska drilling and wells manager. "We're going through kind of a concept selection phase ... and one of the things that we don't know is how we're going to handle all this production, because it is dif- ferent." "This multi-lateral technology has unlocked the flow potential," said Johnson. "now we can finally get that reservoir to flow at economic rates - and that's been the challenge for the last 20 years. ..." There are other issues now connected with gctting viscous production to the sur- làce, "but the key thing is that this multi- lateral has unlocked viscous oil." Christman said the horizontal footage drilled in the quad-lateral well, the 25,000- lèet of horizontal hole, has "nol been done anywhere else in the world: it's just huge, just huge stuff." The issues, now, Christman - said, are sand control and long-term serviceability of the multi-lateral wells: "The mullilaterals are there, but do we know we can keep them all producing for many, many years? "It will be a sand control issue... And "Horizontal 11lulti-lateral wells . l1ave been the hey to unlochil1g those (viscous) reserves... predominately through efficient geo-steeJing within the segregated sands... Rather than undulating throug~~ them, we actually stich dedicated là~erals into each one of . the sand intervals." - Mik Triolo, BP Exploration (Alaska) drilling engineer long-tenn well serviceability," he said. Well design evolved here The men said this is a slope-wide effort, with a slope-wide viscous team including SP, ConocoPhillips and ExxonMobil, working the viscous development issue, and contractors for the ftnns developing the technology being used. Triolo said that while the wcll design in use al Orion was evolved at OP, "we've also shared this well design with ConocoPhillips and so they're using it on their development," and ConocoPhillips is "Ieaming things over there that they're sharing with us," as part of the regional vis- cous team. ConocoPhiIlips operates the Kuparuk River unit viscous West Sak development effort. The quad multi-lateral has been drilled, and a quintuple multi-lateral is planncd for later this year, Triolo said, the first such well on the slope. That well, however, is nol planned with five junctions coming out li'OIn the main well bore, because "some of these sands are so thin that they cannot eco- nomically support the cost of a multi-later- al junction," so coilcd tubing technology will be used to do an open-hole junction. Four laterals will come otTlhe main well bore~ one of those laterals will split again. The whole well will be drilled with a rotalY rig, Triolo said, but will use some coiled-tubing developed technology, scaled up in size to rotary applications. Some of that technology was developed for usc over at Kuparuk, he said, so there is technology sharing among the di Oèrcnl drilling groups, as well as between l3P and ConoeoPhillips.

Then continue with 1 rigid straight vane centralizer per joint floating to 4,600' MD (780' MD above Ma sand). Zonal isolation with cement is required between the OA and the Nb sands due to the presence of water in the Nb sand. The centralizer program is subject to change pending modeling and hole conditions. 4 "'h" Solid Liner Centralizer Placement a) Run one straight blade rigid centralizer per joint, floating between the collars.

If hydrates are encountered follow the recommended practice and apply good drilling operational practices. III. Lost Circulation/Breathing A. lost circulation is unlikely within the Schrader interval. B. We do not expect breathing on this well as we are above the more prevalent breathing shale's i.e. Seabee. IV. Kick Tolerancellntegrity Testing A. The 10-%" casing will be cemented to surface. B. The 7_%" casing will be cemented with 15.81b/gal tail cement to 700' MD above the Ma sand -4,680' MD. C. The Kick Tolerance for the surface casing is 52.7 bbls with 9.2 ppg mud, 11.4 ppg lOT, and an 8.9 ppg pore pressure (most likely 8.9 ppg based on recent MDT's within the block). If the LOT is less then 11.4 ppg EMW, then the kick tolerance will be < 50 bbls. D. The Kick Tolerance for the production hole laterals is infinite with 9.2 ppg mud, 12.0 ppg FIT, and an 8.9 ppg pore pressure. If the FIT is less then 12.0 ppg EMW notify the ODE to have conversation on how to deal with potential ECD concerns around the casing exit points. E.

We do not expect stuck pipe. B. There could be slight differential sticking across the reservoir while running the slotted liners. Keep the liners moving as much as possible and run one centralizer per joint to help with standoff. VI. Hydrogen Sulfide A. l-Pad is not designated as an H2S site, however Standard Operating Procedures for H2S precautions should be followed at all times. Recently 10 ppm of H2S has been measured at L-Pad from all wells tested as recently as January 2003 with hand held H2S meters. This is as a result of H2S being transmitted by shared gas lift gas and not produced from L-Pad. There has been no seawater injection at l-Pad to date. VII. Faults There are four visible faults to cross while drilling the well. It is possible to encounter sub-seismic faults along the proposed well path. In the production hole sections, if a fault throws us out of section steer up as fast as possible to determine where we are within the section. This will make it easy to lowside OH sidetrack to get back on course.
