NORTH SLOPE :)O:--F'+7 /0 3/ lot PETROLEUM NEvVS 9 PBu L-J-o LI BP cOInpletes quad-lateral at Orion Drilling end of viscous equation appears solved; production of heavy oil still an issue because of sand produced \J\lith oil and lvell rnaintenance issues By KRISTEN NELSON PeLroleum News EdiLor-in-Chie! The viscous oil resource on Alaska's NOlih Slope - like the natural gas resource there - has been known fOl~ 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. Bf> 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 dcvclop- . ment in the western Prudhoe I j /2 fi\~jW satellites. ' ..'- " Multi-lateral horizont.al S E R I E S wells have solved the drilling side or 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 SUrf~ICC and are colder, less mobile and have poorer reselVoir quality than conventional crude oil, said Mik Triolo, Greater Prudhoe Bay operations drilling engineer. Triolo worked the Schrader ßlufTviseous accumu- lation at 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 Pmdhoe Bay westel11 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 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) reselVes... predominate- ly through efficient geo-steering within the segregated sands... Rather than undulating through them," Triolo About the series Editor s Note: lv/embers of BP Axploration (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 StOfY, printed in the Oct. 10 issue of Petroleum News, included all overview of the compallY S North Slope drilling activity and an update on its coiled tubing drilling pro- gram. Part 2,uwhich 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 one of the sand intervals." In addition to better ability to steer through the foonations, drilling also helps vis- cous oil development with "good well design," he said. A cmcial part of the well is where the laterals branch fi'om the main well bore, and BP has also been trying different junction designs, the connection between the main well bore and the lateral. At Milne Point BP detennined "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-three 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-entry capability of the junction and how well it seals or iso- lates at that junction." Re-entry capability and the seal see DP page 10 10 ,~e continued from page 9 BP -;;f: ~ 4: ~ Z o . provided are the two primary things a junc- ~ tion does, he said. ~ Triolo said BP detemlined "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 ~ :::I choice." 8 First level-three, quad-lateral weD 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 . I expenSive for the wells group to maintain: "We didn't really have cost-effective ways to work on the wells or impact the flow streams of the wells later in life, so we went baek to the drawing board and came up with some criteria that we wanted to see achieved in our well dcsigns, 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 dlì- ciency to the full life-cycle cost of the well," Triolo said. Wcll work can now be done through the tubing, with a coiled tubing unit, without the need for a workover rig. The to1.11 footage in the quad-lateral well, Prudhoe Bay unit L-20 l, was almost 35,000 feet, with "almost 28,000 feet of horizontal footage within these thin bedded sands," more than five miles of horizontal footage in onc wcll, Triolo said. There wcrc cleanup issues with the well, and BP didn't realize fulll10w potclltial, but the well had a productivity index of 40 (a measure of barrels per pound of square inch drawdown), compared to 1110st wells on the slopc somewhcrc in thc 20-rangc. "lfwc could havc opencd it up full bore, we probably would have bccn somewhat tubing limited," he said. Facility limited Right now thc well is facility limited, Triolo said. Darcn ßeaudo, UP's dircctor of public affairs, said one of the things SP worked on during the summer production G~M~.I;t,.

"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," Beaudo 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 sand in thc reselvoir. Not only does sand accumulate in pro- duction facilitics, said Andy Kirk, BP's Alaska drilling and wells perfOlmance con- sultant, but it also causes problems in pipelines because it is corrosive - another reason to keep it in the foonation. And i r a Illulti-Iateral well has to be shut in and thc oil stops flowing, Kirk said, the santi can layout along UIC horizontal portion oCthe 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 opp0l1unity for viscous' is huge: - ~- w 7~~~·~~~,\;;~~!_.~~~~~ some 1.6 billion barrels recoverable with current technology, said Gary Christman, BP's Alaska dri1ling 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 now 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- /àce, "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- fect of horizontal hole, has "not 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 scrviceability of the multi-lateral wclls: "The multi laterals 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 multi-lateral wells Itave been tlte hey to unloching those (viscous) reserves... predominately through efficient geo-steering within the segregated sands... Rather than undulating througJ~the1n, we actually Stiell dedicated ld.!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 BP, ConocoPhillips and ExxonIvlobil, working the viscous development issue, and contractors for the flnns developing the technology being used. Triolo said that while the well design in use at Orion was evolved at BP, "we've also shared this well design with ConocoPhiUips 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 drilled, 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 "somc of these sands are 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 off the main well bore; one o[those laterals will split again. The whole well will be drilled with a rotalY rig, Triolo said, but will use some coiled-tubing dcvelopcd technology, scaled up in size to rotary applications. Some of that technology was developed for use over at Kuparuk, he said, so there is technology sharing among the dilTerent drilling groups, as well as betwccn BP and ConocoPhillips.

Casing Space Out a) Space 7-%" casing out with pups and long/short joints as required to place the top of a long full joint - 5- 15' above the top of the OBb, OBa and OA sands to allow for the window to be milled just below the top of each sand and in the middle of a full joint of casing. 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.

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.

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 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. Kick Tolerancellntegrity Testing A. The 10-%" casing will be cemented to surface. B. The 7-%" casing will be cemented with 15.8lb/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.

Keep the liners moving as much as possible and run one centralizer per joint to help with standoff. VI. Hydrogen Sulfide A.

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.
