`
`record for the Book as of July 22, 2016 under the “Librarian View” tab at the
`
`following web address:
`
`httpflfdiscovery.1ibrary.colostate.edufRecordi’.b22793069fDetails. Attached as
`
`Exhibit C is a true and correct copy of a screenshot that I generated of the
`
`bibliographic entry for the Book in CSU Libraries’ ILS software. Attached as
`
`Exhibit D is a true and correct copy of a screenshot that I generated of the item
`
`record for the Book in CSU Libraries’ ILS software.
`
`The title listed in Appendices B, C, and D has a minor typographical error
`
`that refers to “Operations” instead of “Operation” within the phrase “Production
`
`Operation Symposium.” However, other information confirms that the records
`
`shown in Appendices B, C, and D refer to the Book. The remainder of the title
`
`(including “2-4 April 1995” and “Oklahoma City, OK” shown in Appendices B, C,
`
`and D matches what is shown on the cover page in Appendix A, and the 1995
`
`copyright date in Appendices B, C, and D matches the 1995 date shown on the
`
`copyright page in Appendix A. Also, the unique identifier “S-A-23B-1 l-08—0l3”
`
`listed alongside field 945 in Appendix B and near the bottom of Appendix D
`
`corresponds to the number shown on the title page in Appendix A.
`
`CSU Libraries’ records confirm that the Book was catalogued, and therefore
`
`made available to the public, at CSU Libraries on February 8, 2000. Appendix B
`
`Page 2 of 19
`
`

`
`“000208” in part “|c” alongside the second field 998. The first of these date fields
`
`is user~entered on the day on which a book is catalogued and made available to the
`
`public. The second of these date fields is system-generated on the day on which
`
`the bibliographic record for the Book was created in CSU Libraries’ ILS System
`
`software records, and this date field is not editable. Appendix C also shows these
`
`dates as “CAT DATE 02-08-2000” and “Created: 02-08-2000,” respectively.
`
`Appendix D also shows the second date as “Created: 02-08-2000.”
`
`Books are made available to the public as soon as they are catalogued, which
`
`often occurs on the same day that they are entered into the CSU Libraries ILS
`
`sofiware, as CSU Libraries’ records show was the case for the Book.
`
`I declare under penalty of perjury that the foregoing is true and correct.

`
`All papers in this volume were presented at the Production Operations Symposium held in
`Oklahoma City, OK, 2-4 April 1995. Permission to copy is restricted to an abstract of not more
`than 300 words. Illustrations may not be copied. The abstract should contain conspicuous ac-
`knowledgment of where and by whom the paper was presented. Any other use of material in
`this volume is subject to prior approval, in writing, and payment of any applicable fees. Con-
`tact the Librarian at SPE Headquarters.
`
`Discussion of the papers is invited. Three copies of any discussion should be sent to the Society
`of Petroleum Engineers office. Such discussion may be presented at the Conference and, with
`the paper, may be considered for publication in one of the SPE journals.

`SINGLE-TRIP COMPLETION CONCEPT REPLACES MULTIPLE PACKERS
`AND SLIDING SLEEVES IN SELECTIVE MULTI-ZONE PRODUCTION AND
`STIMULATION OPERATIONS

`
`ABSTRACT
`
`In conventional multi-zone completion operations, selective
`production and/or stimulation requirements are accomplished
`by opening and closing sliding sleeves in each producing
`' zone. This completion method requires at least one trip per
`zone as well as substantial amounts of equipment in the well.
`An alternative method that is being field tested will move the
`internal control of the well from the tubing string to the cas-
`lng. This eliminates equipment from inside the well and re-
`duces the number of trips required from one per zone to a
`Single trip forthe entire well. This paper describes the single-
`trip completion concept, primarily for horizontal wells, as well
`as the new technology that has been developed to support
`it.
`
`CURRENT HORIZONTAL COMPLETION OPTIONS
`
`For horizontal wells, completion technology has historically
`iagged behind drilling innovations.
`in the past couple of years,
`however, completion options for horizontal wells have in-
`Creased and now range from the simplest open-hole method
`
`
`A Reference at end of paper
`
`to cemented and perforated casing completions. The more
`complicated completions put heavy emphasis on zonal iso-
`lation, and attempt to reduce cost at the same time. Current
`options are outlined below. Each has its own set of merits
`and limitations.
`
`OPEN HOLE
`
`Open hole is the simplest form of horizontal completion. As
`its name implies, the horizontal section of the well is left open.
`This technique is very inexpensive and is well suited for stable
`formations where very little if any zonal isolation is needed.
`The most common application for open-hole completions is
`in fractured limestone or chalk formations. One major ad-
`vantage, other than the cost itself, is that the formation has
`little damage from the completion because of the absence
`of cement. On the other hand, the absence of casing se-
`verely limits the operator’s remedial options and all but elimi-
`nates the ability to perform zonal isolation. The only option
`available for these operations is to use inflatable packers to
`shut off part of the well for remediation and limited zonal
`isolation.

`
`The only difference between open-hole and slotted liner
`completions is the addition of a slotted liner in the horizontal
`section of the well. The slotted liner provides the well with
`the added stability necessary for some formations without
`adding substantial cost or complexity over the open-hole
`completion. The added stability maintains the integrity of
`the well and helps prevent cave-ins from stopping or severely
`restricting production. This becomes increasingly important
`as the formation pressure decreases from production.
`
`A slotted liner is not very effective for sand exclusion, and is
`susceptible to plugging. Therefore, a sand screen is some-
`times used in place of the slotted liner to control the sand
`infiltration. The chief drawback of the slotted liner comple-
`tion is that it removes any possibility of remedial or zonal
`isolation. The need to isolate zones becomes more appar-
`ent as the well matures and begins to water cone or be-
`comes depleted from existing fractures.
`
`in this type of completion, sliding sleeves can be opened
`and closed using coiled tubing shifting tools. These tools
`are normally hydraulically activated so the shifting of the
`sleeves is very easy and selective. The use of the sliding
`sleeves also gives the operator the option of acid or low.
`volume sand fracturing. The fracturing effectively increases
`the life of the well by increasing the payout.
`
`The ECP sliding sleeve completion has some drawbacks.
`For example, the formation, if not stable, can collapse. on the
`tubing and shut off access to the sliding sleeve.
`If the forma-
`tion collapses then it could possibly choke off production from
`that zone. Additionally, effective isolation between forma-
`tions is limited by ECP length (up to 40 ft), so extremely po-
`rous formations (i.e. sandstone) can flow around the ECP
`and cancel any zonal isolation the operator engineered into
`the completion. On the other hand, ECPs set in imperme-
`able shale work well as a barrier. The hole size is also an
`important consideration. Setting ECPs in a washout can
`result in failures. These wellbores also increase with age,
`again increasing the life of the zonal isolation.

`
`The ECP and sliding sleeve completion is still relatively simple
`to run. (Fig. 1)
`it is run in open hole, and the ECPs (external
`casing packers) are set using hydraulic pressure. The addi-
`tion of the sliding sleeves and ECPs increases the cost of
`this completion over the previous two.
`it increases well con-
`trol and, with it, remedial and zonal isolation options avail-
`able to the operator. The increased well control usually off-
`sets the increase in cost. This is most apparent in remote
`areas or offshore.
`
`The next evolutionary step of the ECP and sliding sleeve
`completion is the addition of a cased and cemented hole-
`(Fig. 2) This is required where zonal isolation is necessafY‘
`The cement prevents the formation from leaking around the
`ECPs. This type of completion provides the operator with
`more options for stimulation, greater well life, and excellent .
`isolation of zones, as in a typical vertical well. Well life 55 ,

`fracturing. With a cased and perforated hole, a wide variety
`of
`remedial tools become available. With all the advan-

`back, along with extra trips required to perforate the zones.
`
`EVOLUTIQN OF A HEW COMPLETIQN SYSTEM
`
`Each of the above completion methods has its merits. ‘The
`more well control required, the more expensive the comple-
`tion becomes, just as in the evolution of vertical wells.
