The PPC (Powered Positioning device and Caliper) is anEFTB tool and has been developed as a multi purposefour-arm caliper. Independent movable caliper armsprovide an accurate hole-volume computation evenwith tool eccentering.

Depending on the requested job type, the PPC worksas an active positioning device (such as; adjustableforce centralizer, short-axis positioning device,eccentralizer, or active standoff). The PPC not onlyworks as a caliper, but it also works to improve thedata quality of sonic tools, density tools and others.

With the PPC log-down kit attached, the PPC is ableto provide an open caliper and keep the tool eithercentered, or on a short axis when going down to TotalDepth (TD).

One of the features of the PPC is its adjustable “armpressure” function. You can change the arm pressureby sending AC-AUX power from Surface. If you wantto centralize the toolstring in a highly deviated hole,you can apply high-arm pressure to centralize thetoolstring. A maximum of four PPCs can be combinedin the same toolstring. This function was developedbecause some PPCs may be used as centralizers andsome PPCs may be used as short-axis positioning toolssimultaneously in the same toolstring.

The other feature of the PPC is its selectable set up.You can change each caliper set up as either poweredor non-powered.

• If all four calipers are set up as powered, the PPCcan be used as a centralizer (centering set up).

• If two of the four arms are powered, the PPCis aligned in the long-axis, and can be used forthe short-axis logging for tools in combination(short-axis logging set up).

• If one of the four calipers is powered, the PPC canbe used as an eccentralizer (eccentering set up).

These set ups are only changeable at the surfacebefore the run in-hole.

Since the PPC has the EMS cartridge (EMC) functionfor caliper measurement, it is possible to connect theEMS sonde (EMM-6 arm caliper sonde) directly belowthe PPC without using the EMS cartridge (EMC). Ifyou use a 45° adapter head (AH-255) and dual PPCcombination (PPC-AH45°-PPC) to produce an 8-armcaliper, the data combination of two PPCs can only bedone on Well CAD 3D.

1.1.2 Principal applications

The PPC is a four-arm caliper tool whose calipersare able to move independently and provide boreholeradius. By processing caliper measurements, the PPCproduces oval hole graphics, Well CAD 3D interfacefiles.

An important role of the PPC is to improve data qualityof the tools in combination, such as a sonic or densitytool, by providing proper positioning of the toolstring.

Adjustable force centralizer: The PPC works as anadjustable force centralizer to centralize the toolstringin a vertical or deviated well. You need at least twoPPCs to properly centralize the toolstring, and all of thecaliper arm settings must be in the powered position(centering set up.)The recommendation is to put the PPC above andbelow the tool to be centralized. The PPC providesfour-arm caliper measurements and by monitoring

that data, you can adjust the required centering force(caliper pressure.) Required centering force dependson the hole deviation and the weight of the toolstring.

Short-axis positioning: The PPC works as a shortaxis positioning device when only two of the caliperarms, which are perpendicular to the density caliper,receive caliper pressure (short axis logging set up.)Since this pair of powered PPC calipers is naturallyoriented to the long axis in the oval hole, the densitycaliper orients to the short axis as a result.

Eccentralizer: The PPC works as an eccentralizerwhen only one arm is powered (eccentering set up.)Since this set up allows supplying arm pressure only toone of the arms, this single arm pushes the toolstringagainst the borehole. You can select which caliper topower.

Log-down kit: When the PPC log-down kit isattached, you can open the caliper while the tool isgoing downhole. By doing this, you can centralize ororient the toolstring to the short axis during log down(e.g., sonic log down.)

Active standoff: The PPC can also be used as anactive stand off. Active standoff means that by openingand applying caliper pressure, the PPC works as astandoff and then the caliper can be closed when it isnot needed.

ExampleWhen you run the CMR tool inhole, the strong magnetmay stick to the casing and make it difficult to lowerthe tool. In that case, the PPC, which is connectedbelow the sonde with log-down kit attached, works asan active standoff.

Multiple PPC operation: Multiple PPC operationmeans you can combine a maximum of four PPCs inone toolstring.In case of OP/MAXIS, under the LES window,PPC displays the “PPC1-B” “PPC2-B” “PPC3-B”“PPC4-B” buttons.



Common Equipment

The number of PPCs is important since caliperoperation command, presentation format, signals, anddata channel names are distinguished by that number.For the normal logging, always select “PPC1-B”for single PPC use and select in order PPC1,2,3…for multiple PPC operation. When you declare thetoolstring, select “PPC1” as the top PPC in thetoolstring.In case of MaxWell, the system automatically indexesthe number for each PPC on the tool string. The userdoes not have to take care of the index numbers.

PPC-EMM integration: The PPC electronicsincludes the function of the EMS cartridge (EMC);therefore, the EMS sonde (EMM) can be connecteddirectly below the PPC without the need for an EMC.This PPC-EMS combination provides 6-arm caliperdata from EMM.

1.1.3 Telemetry information

The PPC telemetry is EDTS and combinable with EFTBand FTB tools. Refer to 2.1.2 for detailed information.

1.1.4 Tool combinability

The PPC uses AC-AUX for the caliper operation(open/close/powered) so special care is needed tocombine the PPC with Highly Integrated AzimuthalLaterolog sonde (HALS).

• AC-AUX causes noise for the HALS measurement.

• PPC arm control is not allowed during HALSlogging.

1.1.5 Tool history

Although the PPC does not have a direct predecessor,the EDAC and the EMS are both multi-arm calipers. TheEDAC is used for the density short-axis logging withdensity tool.

NoteBecause the upper head of the PPC is made of 17-4PH,which is a magnetic material, 6-ft of non-magnetichousing is necessary between the GPIT and PPC if theGPIT is placed above the PPC.The PPC lower housing (2 ft) is non-magnetic; if theGPIT is placed below the PPC, then 4-ft additionalnon-magnetic housing is necessary between the PPCand GPIT.

Note

If you connect the PPC-B30 with a 3 3/8-in standard toolwhich is rated below 30,000 psi, change the threadedring from 100554574 to H339565 on the upper housingof PPC-B30. Otherwise, you risk breaking the lowerhousing of 3 3/8-in tool even if the pressure is lessthan 20,000 psi. Meanwhile, the lower interface of thePPC-B30 fit in 3 3/8-in, 31-pin standard.

NoteThe gross centering force for one arm (RB = 0°, 90°,180°, 270°) is 140 kgf, and for two arms (RB = 45°, 135°,215°, 315°) it is 198 kgf. This is calculated as below;One arm:

2.1.4 Service combinability

NoteThe PPC does not have DTB through-wires; do notconnect DTB tools below the PPC.

Since the PPC is an EDTS telemetry tool and not abottom-only tool, the PPC can be put any place withinthe FTB and EFTB toolstring.

For short-axis logging, put the PPC above the densitytool so that the pair of powered arms can lead alongthe long-axis of the oval hole zone. That way, thePPC is positioned at the center of the hole but sincethe density tool is usually eccentered during logging,it is highly recommended that you put two knucklejoints (e.g., AH-107) with the PPC for the density toolcombination.

Typical tool combinations are:

• Sonic centering: LEH-QT - DTC-H - PPC - DSI - PPC

• Short-axis logging with standard arm:LEH-QT - DTC-H - AH107 - PPC - AH107 -(HGNS-HRCC-HRMS-AIT)

Potential Severity: LightPotential Loss: AssetsHazard Category: Machinery

equipment handtools

Do not use the above combination with the logdown kit. With this string the PPC can tilt slightlyso the long contact pad of the log down kit maydamage the formation by mechanical movement ofthe log down kit.

• Short-axis logging with log down kit: LEH-QT -DTC-H - PPC-(ie.Sonic tool) - AH107 - AH107 -(HGNS-HRCC-HRMS-AIT)

• PPC-EMS integration: LEH-QT - DTC-H - PPC -EMM

Refer to section 3.3.1: PPC-EMM integrationprocedure.

3. AH-255, 45/315° rotatable (100056945)For use with two PPC connections with a45° rotation axially to allow an 8-arm calipermeasurement. This adapter is adjustable eitherplus or minus 45°. To align the key positions of thetools above and below the PPCs in-line, use twoAH-255. The ratings of the AH-255 are 20 Kpsi and275 degC.

Figure 3-3: AH-255, 45/315° rotatable

4. 17-in extension arm (100059824)Allows an extension arm with up to 40-in calipermeasurement, or one arm operation up to 21 in asan eccentralizer.

6. AH-256, PPC upper 0.7-in offset (100067392)When using the PPC as an eccentralizer. The PPCradius to the contact face with eccentralizer setupis 2.3 ft (max OD is 5.25 in). Therefore, it makesan offset of 0.6 in between contact faces of a 33/8-in tool and the PPC. There is a 0.7-in eccenteredadapter to prevent the effect of the offset for theeccentering tool facing contact to borehole. Thisadapter is also adjustable to rotate the PPC 45°axially, if desired. The rotate function of the PPCcan be used like an existing short-axis device toposition the eccentering tool in-line with the shortaxis. This adapter is used for the PPC upper head.
