501IntroductionThis document provides information onthe operation and handling of equipmentsupplied by Sperry Drilling. All equipmentsupplied by Sperry Drilling has a specifiedmaximum limit of operation. Operatingthe equipment close to these specifiedlimits for certain parameters will causeaccelerated wear or damage to theequipment. Operating ranges for SperryDrilling equipment are defined as follows:» Normal Operating Range — The tools arerun below the specified limit of operationor the start of the harsh environmentrange if applicable.» Harsh Environment Range — The toolsare run below the specified limit ofoperation, but the conditions are at orclose to the maximum limit, which causesaccelerated wear or possible damage tothe equipment.HAL123725» Exceeded Specified Limit — The tools arerun in conditions outside of their designedoperating limits, and immediate damageto, or excessive wear of, the tool is likelyto occur.Use of the equipment in either a harshenvironment or above the specified limitreduces its useful life. A repair charge willapply if a tool is used in a Harsh EnvironmentRange, and a higher charge will apply if a toolhas Exceeded a Specified Limit (ESL). ThePrice Book specifies these additional charges.The following sections define the HarshEnvironment Range and specified limit ofthe controlling technical specifications (e.g.,temperature, weight on bit, dogleg severity,vibration, revolutions per minute (RPM),flow rate, pressure, solids percent, andsand percent).Certain operational circumstances thatimmediately exceed the design specificationof the tools are also identified, (e.g.,rotation of the tools with no mud flow). Ifthe equipment is operated under any ofthese identified conditions, it is regarded asExceeding the Specified Limit.Where a specified limit has been exceeded,any subsequent equipment failure will bedeemed to be caused by improper use ofthe tool and any nonproductive time should,therefore, not be attributed to Sperry Drilling.
702Technical Data Sheet Clarifications» Stated tool diameter, length, and sensor distances are nominal tool dimensions.» Maximum tool rotation is the rotational speed of the sub, collar, motor, or rotarysteerable in revolutions per minute.» The maximum rotation level stated is only for drilling ahead in a new formation.When drilling cement or rotating off bottom, the maximum rotational level will needto be reduced based on the specific operation. Any maximum rotation speed willalso have to be determined by the specific operation and with reference to vibrationmeasurements.» The torque specifications provided in the Technical Data Sheets are right-hand(clockwise, looking downhole) torque.554 01A2624» Maximum pressure, as stated in the Technical Data Sheets, is hydrostatic pluscirculating pressure.» Certain tools may have individual specifications that differ from values contained in thisdocument arising from unique design requirements for that tool. The individual tooldata sheet or the DS-1 transmittal report will identify these exceptions.
903Criteria for Harsh Environment andExceeded Specified LimitsFor all Sperry Drilling tool strings, the operating limit is determined by thecomponent in the tool string with the lowest specified limit.Certain operating limits can be increased by following the HalliburtonManagement of Change (MOC) process and obtaining approval fromSperry Global Operations.3.1 TEMPERATUREHigh temperature is detrimental to the electronics, solders, and elastomersused in Sperry Drilling tools, and this degradation increases exponentiallyas temperature increases.The table below details the start of the Harsh Environment Range and thespecified limit for the tools.HAL587893.1.1 Measurement-While-Drilling/Logging-While-Drilling ToolsHarsh Environment RangeSpecified LimitStandard Toolsabove 125 C (257 F)150 C (302 F)SOLAR Toolsabove 150 C (302 F)175 C (347 F)Quasar Pulse M/LWD Serviceabove 175 C (347 F)200 C (392 F)3.1.2 MotorsThe temperature limit for Sperry Drilling motors is dependent on the motortype and on the operating differential pressure used while drilling. Contactyour Sperry Drilling representative for the specified limits of the equipmentintended for use.

For the 7-3/4-inch, 8-inch,and 9-1/2-inch positive pulse systems at flow rates of more than 1,100gpm/4,164 lpm, the sand content is limited to 1 percent or less and the bitrun duration is limited to 75 hours.HAL38615Turbodrills should be limited to a sand content of 1 percent for optimalefficiency. This can be increased up to a maximum of 2 percent, althougha reduction in component life will occur. Contact your Sperry Drillingturbodrill representative if planning to run at these levels.SperryDrill and GeoForce motors should be limited to a sand content of1 percent for optimal efficiency. Sand is highly abrasive and high mud sandcontent can greatly accelerate motor component wear. Solids content shouldbe minimized for given applications to promote reliability and longevity, andminimize wear and the possibility of internal motor blockage. Contact yourSperry Drilling representative if planning to run above these levels.iCruise rotary steerable tools have a specified limit of 2 percent for all tool sizes.
11Downhole Equipment Technical Specification Information3.3 LOW GRAVITY SOLIDSA high concentration of low gravity solids (LGS) is detrimental to theperformance of all downhole tools and can lead to tool erosion. Aconcentration of 6% LGS is the specified limit for all Sperry downhole tools.3.4 LOST CIRCULATION MATERIALSThe positive pulser has a limit of 40 lbm/bbl (114 kg/m3) medium nutplug,fine Kwik-Seal lost circulation material (LCM), except for the 3-1/8-inchtools which are limited to 20 lbm/bbl (57 kg/m3).Fibrous LCM is not recommended and may lead to interruption in realtime mud pulse telemetry. Strict adherence to the LCM manufacturer’srecommended concentration and mixing guidelines is required.Turbodrills can tolerate granular and limited fibrous LCMs. Nutplug LCMis not recommended, as it can lock the turbodrill’s internal components.Contact your Sperry Drilling turbodrill representative for detailedinformation on products and concentrations that are compatible with theturbodrills and materials that are incompatible.iCruise has an LCM limit of TIER-1 50 lb/bbl / TIER-2 84 lb/bbl – WAL-NUTT Medium.3.5 MEASUREMENT-WHILE-DRILLING/LOGGING-WHILEDRILLING MASS FLOW RATEAll insert based tool sizes have a mass flow limit, ppg x gpm (kg/l x lpm).Tool Sizelbm/minkg/min9.5 in.20,0009,0708 in.

For straight motors in straight hole applications, permissibleoverpull values that may be applied to the motor housings or bit, and,therefore, driveshaft and thrust bearings, can be obtained from theindividual motor specifications in Section 1.2 of the SperryDrill TechnicalInformation Handbook.The application of high overpull loads on bent housing motors, particularlyin doglegs, can result in high bending stress levels in motor housings andconnections. If possible, bent housing motors should be oriented so thebend follows the hole curvature, prior to the application of overpull loads.In high dogleg situations, directional drilling support personnel should becontacted to obtain correct overpull values.

2304Drillstring VibrationTools that are subjected to vibration and shocks will have their expectedlife reduced or will incur serious damage. Tools that contain electronics andsensor packages are particularly vulnerable.During drilling, reaming, and backreaming operations, vibration levels mustbe closely monitored and maintained below the specified limit of the toolsbeing used by applying vibration management procedures. It is acceptedthat tools may be briefly exposed to high levels of vibration before thevibration is controlled and hopefully eliminated. Damage may result whenthese high levels of vibration are sustained.The following tables define low, medium, and high levels of vibrationseverity together with the specified limits for various types of tools.The specified limit is defined by reference to the measured severity of thevibration and either its duration or number of events; the tool is deemedto have Exceeded Specified Limits when one of the criteria is exceeded.The durations or number of events are cumulative for the individual toolstring being run.HAL35341The Harsh Environment Range is entered into when equipment issubjected to high (red) vibration levels on any axis for any period of time orto a number of events that are less than that defined for the specified limit.
