Bear Claw® Drillable Composite Plugs

Features and BenefitsBear Claw® Drillable Composite Plugs are cased hole composite plugs used for multiple zonal isolation. They are available for 04.5 and 05.5 diameter casing.

Materials• Aerospace grade composite materials with high

temperature & chemical resistance.• High temperature thermoplastics replace brass and

other non-ferrous metals.• Proven oil field elastomeric element systems for

reliable, rugged performance.• Fullcircumferencegraycastironslipsmachinedfrom

bar stock for exceptional uniformity and strength.

Gripping Power• More gripping teeth per slip compared to many

competitive products.• Serratedtoothdesigncutsthroughscale,greaseand

dirt.• Mandrelissecuredviaaratchetingmechanismin certain models.

Drill Out• Doesnotcontaintungstencarbide,largesteelparts

orotherdifficult-to-drillmaterials• Reducesdrillouttimeandcasingdamagecompared

to cast iron plugs.• Lowdensitynon-metalliccuttingscirculatequicklyand

easily back to the surface.

Field Configurable• BearClaw®plugcanbeshippedfromthefactoryas

frac, drop ball or bridge plugs.• Alternately, fracanddropball plugscanbeshipped

depending on the needs of the operator.• Dropballoperationsaredonebysimplyremovingthe

ball retaining pin or using the ball in a separate kit.• Densityofstandardphenolicballis1.32g/cc.Other

densitiesareavailableonrequest.

Running and Setting Procedures:• Runspeedsupto300feet/min[91m/min]depending

on well conditions.• Compositeplugattachmenttosettingtoolusestools

and procedures familiar to wireline crews.• 04.5 plugs use Baker No. 10 and Halliburton 02.5

Shorty setting tools.• 05.5plugsuseBakerNo.20orTitan35/8setting

tools.• Usequickburningorstandard(lessthan10seconds)

Composite Plug Ratings:• Bear Claw® Drillable Plugs are rated to various

temperaturesandpressuresupto350°F[177°C]and14,000psi[96.5MPa](above)/10,000psi[68.9MPa](below).

°F [177°C] andpressures up to 14,000 psi [96.5MPa] from aboveand 10,000 psi[68.9 MPa] frombelow. These plugs are designed to run and function like a cast iron drillable plug with drill out times comparable to the best composite plugs.

Plug Compositions and Backing Ring DesignsBear Claw® 2 uses the same aerospace grade composite materials and premium elastomer elements as the Bear Claw®1plugbutcomeswithseveralelastomerelementsand backing ring systems designed for a variety of customer needs.

• Conventional Element System– designed for lowestcost and fastest drill out for wells up to 300 °F[149°C]anddifferentialpressuresupto10,000psi[68.9MPa](fromabove)and8,000psi[55.2MPa](frombelow).Elementsareavailableinstandardandchemical resistant grades depending on your well environments.

• ArcturusArray–designedasanadvancedbackingringsystem for long duration frac operations or constant reservoir containment. The arrays use an elastomeric center element in standard or chemical resistant grades and lightweight metal/composite reinforcedouter elements which give premium high temperature performance with easy drill out. Depending on casing diameter and the upper well temperature the ArcturusArraysareavailableintemperatureratingsupto350°F[177°C]anddifferentialpressuresupto10,000psi[68.9MPa](fromabove)and8,000psi[55.2MPa](frombelow).

• Ecner Array – designed using proven materials andprocesses pioneered in the retrievable packer industry. Ecner arrays use a premium, high temperature,chemically resistant center element with rubber/stainlesssteelmeshouterelements.EncerArraysareratedto350°F[177°C]anddifferentialpressuresupto14,000psi[96.5MPa](fromabove)and10,000psi[68.9MPa](frombelow).Thisdesignhaspassedaweeklongendurancetestof10,000psi[68.9MPa]differentialfracpressureat300°F[149°C].

Running ProcedureThe Bear Claw® Composite Plugs are designed to be rugged and reliable. The following guidelines will assure the plugs perform as expected in your particular well. Though conditions vary and not all problems may be foreseen, the recommendations below will help achieve a good set. In every case, past experience and common sense should be used. Bear Claw® can make no claims of functionality or consider warranty claims if these guidelines are not followed.

1. PlugSelection:Usethecorrectplugforeachwelltemperatureandapplication.DONOTexceedtemperatureandpressureratings.Makesurethecasingsizeandweightcorrespondtotheplug’sspecifications.Theplugratingchangesdependingonthequalityofthecasing.

2. CasingConditions: Casing should be cement bonded before plug use.

9. TensionSubPreparation:Applyalightcoatingofpetroleumbasedlubricanttotheinsidediameterofthetensionsub. This prevents rust from forming between the tension sub and composite mandrel in the event that the assembled hardware gets wet and is left to sit for several days before use. If applicable, thread the safety spring or lock washer on the end of the tension sub.

11.Setting Sleeve Installation: Apply a generous amount of lubricant on the threads. This keeps sand out of thethreads. The amount of sand getting into the threads can be reduced by applying a couple of layers of electrical tape or similar over the gap between the sleeve and setting tool outer diameter.

12.PlugHandling: Bear Claw® plugs are built to be rugged but should not be abused. To avoid potential problems it is best to not allow the Setting Tool weight to rest on the Plug which may crack the slips and cause premature setting.

Note: Slow down for liners, bends and other restrictions. Avoid colliding with the well bottom, other tools, etc.

13.WellConditions: The well should be thoroughly flushed and free of sand at the target setting depth.

04.5 Bear Claw® Composite Plugs

PRODUCTADVISORYDSIThru-Tubinghasreceivedreportswhereusersof04.5”BearClaw® Composite Plugs have experienced problems separatingfromthesettingtoolafterset.Theproblemislimitedto04.5”CompositePlugswithBakerNo.10settingtoolsorequivalentandsomeslowburningchargesincludingtheDiamondbackIndustriesBPC-1300-010/#10SlowSet Power Charge and the Titan Specialties Slow Burn Power Charges.

The problem is that although the plug has been properly set and the shear screws have performed as designed, there is not enough force left in the setting tool at the end of the stroke to push the tension sub completely off the end of the plug’s composite mandrel. This leaves the tool string lightly stuck to the end of the plug.

DSI strongly suggests the following measures to prevent such an occurrence.

1. PowerCharges:Useonlystandardorfastburningpowercharges!

2. ShearScrewInstallation:Eachshearscrewmustbefullythreadedintotheholetoshearproperly.Tighten each screw until it lightly touches the bottom of the hole.DONOTover-tighten.

• If setting a bridge or kill plug use ONLY standard or fast burning charges and ALL SIX (6) custom 3/8x16UNC-2Adogpointshearscrewsprovidedwiththeplug.

• Ifcircumstancesdictateusinga fracorMeltplugANDaslowburningcharge install the Tension Sub using ONLYFIVE(5)custom shear screws provided with the plug.

• Otherwise,04.5”BearClaw®frac,meltandbridgeplugsshouldbesetwithstandardorfastburningcharges andALLSIX(6)custom shear screws provided with the plug.

3. Setting Tools: Use only the setting tool or its EQUIVALENT for which the setting sleeve and tension subwere designed. Setting adapters are available for Baker No. 10 and Halliburton 2 ½ Shorty setting tools. DONOTSUBSTITUTESETTINGTOOLS!

4.
