NORTH SLOPE J<V4- - O~ Î'of3 i /0 t PETROLEUM NEWS 9 p~~_k;¡ BP completes quad-lateral at Orion Drilling end of viscous equation appears solved; production of heavy oil still an issue because of sand produced with oil and well maintenance issues By KRISTEN NELSON PClroleulI! News Edilor-in-C/lie! The viscous oil resource on Alaska's North Slope - like the natural gas resource there - has been known fOI! decades, but heavy oil has been as stranded as gas, stranded in the ground through lack of the technology and knowledge neces- sary to produce it. BP Exploration (Alaska) has been working on ways to produce viscous oil, also referred to as heavy oil, at Milne Point since the 1990s and now also has viscous oil under t!cvclop- ment. in the western Prudhoe / 1. /2 )\¡~:iV satellItes. ... ....... " Multi-lateral horizontal S E R I E S wells have solved thc drilling sit!e 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 closcr to the surl[lce and are colder, less mobile and have poorer reservoir quality than conventional crude oil, said Mik Triolo, Greater Prudhoe Bay operations drilling engineer. Triolo worked the Schrader BlufTviscous aceumu- lationat Milne Point before moving over to Orion, working on the early 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 Prudhoe Bay western satellite viscous oil accumulation. Multi-lat- eral wells, well bores with multiple holizontallaterals into shallow sands containing viscous oil, make wells productive enough to be economic. First tri-Iateral in 2003 In 2003, BP 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-steering within the segregated sands... Rather than undulating through them," Triolo Abóutthe series Editor s Note: Members of BP }.xploration (Alaska) s drilling group sat down with Petroleum News Sept. 28 to talk about the companys development drilling program, recent drilling records and about the technology that is driving the company s North Slope development drilling. Part.l of this story, printed in the Oct. 10 issue of Petroleum News. included an 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 well maintenance work. said, "we actually stick dedicated laterals into each onc of the sand intervals." In addition to better ability to steer through the fonnations, drilling also helps vis- cous oil development with "good well design," he said. A crucial part of thc well is where the laterals branch [¡-om the main well bore, and BP has also been trying dilTerent junction designs, the connection between the main well bore and (he lateral. At Milne Point BP detennined "that the level three, the TAML level three junction, was the junction of choice.. .," Triolo said. lAML stands for Technical Advancement of Multi laterals, an organization set up to regulate "the diffèrent levels of multilateral junction equipment such that everything is standardized," he sait!o "So if Baker comes out with a level-three junc- tion, the eliteria that are set up to distinguish between a level-three and a level-fow, are the same as for Halliburton.. ." The TAML levels, said Mark Johnson, BP senior coiled tubing drilling engineer, "refer to the re-ently capability of the jtUlction and how well it seals or iso- lates at that junction." Re-entry capability and the seal see BP page 10 ~~ 10 , . 11Ì~[']~. continued from page 9 BP :î :.<: ~ ~ z o , provided are the two primary things a jlU1C- ~ tion does, he said. ~ Triolo said BP determined "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 First level..three, quad-lateral wen in world BP took its experience at Milne Point to Orion, a westem Prudhoe Bay satell ite, and this year "we drilled the first level-three quad-lateral multi-lateral well in the world," Triolo said. (The accompanying graphic illustratcs such a quad-lateral multi-lateral well.) BP's initial experience with multi-lateral wells was that complicated wells were . I expensive for the wells group to maintain: "We didn't really have cost-efTective 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 ~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 em- ciency 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 wcll, Prudhoe Day unit L-20 1, was almost 35,000 feet, with "almost 28,000 feet of horizontal footage within these thin bcddcd sands," more than five miles of horizontal footage in one well, Triolo said. There were cleanup issues with the well, and BP didn't realize full How potential, but the well had a productivi(y index of 40 (a measure of barrels pcr pound of square inch drawdown), compared to most wells on the slope somewhere in the 20-range. "If we could have opened it up rull bore, we probably would have been somewhat tubing limited," he said. Futility limited Right now the wcll is f~lcility limited, Triolo said. Daren ßeaudo, UP's director of public affairs, said one of the things 8P worked on during the summer production ~ÆYJñr,AWA;f,. VISCOUS 011. ~UAD fltL COMPLETION .. j~ ~1 d) .. fll .& ill ..l :ií!: -.... ~ 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, not a well-rate issue," 13eaudo 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 keep the saud in the rcsclvoir. Not only does sand accumulate in pro- duction facilities, said Andy Kirk, 8P's Alaska drilling and wells perfonnance con- sultant, but it also causcs problems in pipelines because it is corrosive - another reason to keep it in the fonnation. And if a multi-lateral well has to be shut in and the oil stops flowing, Kirk said, the sand can layout along the horizonlal portion oflhe well, creating dunes which plug up the well, making it difficult to re-establish pro- duction when the well is brought back online. Opportunity huge The opportunity for viscous' is huge: '-.,. ,~}Jjt!!;;-,~~~~Féi~~:;"t-~;:~~~.ç-~;4:D ~L ~7~~~~<1r:~~;,.~c;¡[~J'® some 1.6 billion barrels recoverable with current technology, said Gary Christman, UP'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 gel that reservoir to now at economic rates - and that's bccn the challenge for the last 20 years. .., " There are other issues now connected with getting viscous production to the sur- H1Ce, "but the key thing is that this multi- lateral has unlocked viscous oi\." Christman said the horizontal footage drilled in the quad-lateral well, thc 25,000- feet or horizontal hole, has "not been done anywhere clse 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 multi laterals arc there, but do we know we can keep them all producing for many, many years? "It will be a sand control issue... And ~Dlf-04-''6 PETROLEUM NEWS · WEEK OF OCTOBER 31, 2004 "Horizontal nlulti-Iateral wells have been the hey to unloching those (viscous) reserves... predominately through efficient geo-steeling within the segregated sands... Rather than undulating throug~~ theIn, we actually stich dedicated là!erals into each one of the sand intervals." - Mik Triolo, BP Exploration (Alaska) drilling engineer long-tenn well selVieeability," he said. Well design evolved here The men said this is a slope-wide effort, with a slope-wide viscous team including BP, ConocoPhillips and ExxonMobil, working the viscous development issue, and contractors for the fIrms developing the technology being used. Triolo said that while the well design in use at Orion was evolved at ill', "we've also shared this well design with ConocoPhiIlips and so they're using it on their development," and ConocoPhillips is "learning things over there that they're sharing with us," as part ofthe regional vis- cous team. ConocoPhillips operates the Kuparuk River unit viscous West Sak development effort. The quad multi-lateral has been drillcd, and a quintuple multi-lateral is planned for later this year, Triolo said, the first such well on the slope. That well, however, is not planned with five junctions coming out from the main well bore, because "some of these sands arc so thin that they cannot eco- nomically support the cost of a multi-later- al junction," so coiled tubing technology will be used to do an open-hole junction. Four laterals will come ofTLhe main wel! bore; one of those laterals will split again. The whole well will be drilled with a rotary rig, Triolo said, but will usc some coiled-tubing developed technology, scaled up in size to rotary applications. Some of that technology was developed for use over at Kupamk, he said, so there is technology sharing among lhe di fTerent drilling groups, as well as between 131' and ConocoPhillips.

These KOP's may be altered to enhance reservoir contact depending on the angle of intersection of each zone. b) Place 1 RA tag above each window exit. RA tags to be spaced out -40 - 80' above window depth except on the OBd lateral. It will need to be placed 120' above the casing shoe. c) Emergency 7-%" casing slips can be used instead of the 7-%" mandrel hanger if required for space out. 7-%" String Centralizer Placement a) Centralizer size: 7-%" X 9-Yá" (this is different then the norm of W under gauge hole) b) Do not run centralizers on the window joints spaced at the top of each sand. c) Place 2 rigid straight blade centralizers back to back at the very bottom of the shoe joint. Do not run any centralizers on the next two full joints. d) With the exception stated above, alternate 1 rigid straight vane cenralizer floating across a full joint and 2 rigid straight vane centralizers, one floating on the upper half of the joint and one floating on the lower half of the joint separated by a stop collar up to ±5,830' MD (320' MD above the top OA sand). 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 W' Solid Liner Centralizer Placement a) Run one straight blade rigid centralizer per joint, floating between the collars. If any differential sticking is noticed while drilling, it may be necessary to put another centralizer per joint separated by a stop collar. Do not put any centralization on the first two joints above the bent joint.

Well Control A. The Schrader in this fault block is expected to be underpressured based on the MDT samples. a. OA: 1,970 psi @ 4,370' TVDss (8.70 ppg EMW). Based on L-120 MDT's b. OBa: 2,000 psi @ 4,440' TVDss (8.70 ppg EMW). Based on L-120 MDT's c. OBb: 2,060 psi @ 4,490' TVDss (8.80 ppg EMW). Based on L-120 MDT's d. OBd: 2,140 psi @ 4,600' TVDss (8.90 ppg EMW). Based on L-120 MDT's II. Hydrates and Shallow gas A. Gas hydrates are present below L-pad, but have not been a significant issue thus far during L-Pad drilling. 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 Tolerancenntegrity Testing A. The 10-%" casing will be cemented to surface. B. The 7-%" casing will be cemented with 15.8 Ib/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 lows ide OH sidetrack to get back on course.
