Full bore spinner and continuous spinner

• There is no generic difference between a "continuous" spinner and a "fullbore" spinner. In the case of the fullbore, the spinner element folds into a diameter no greater than that of the tool when in the tubing, but expands into a larger diameter for surveying in the casing. The continuous spinner does not have this capability. The difference between the two is too small to justify a separate discussion of each.

• The continuous meter derives its name from the need to move the tool fast enough to overcome frictional torque and start the spinner element rotating. It also derives its name from the in-situ calibration procedure that uses logging runs at several different cable speeds with the well shut-in at the surface. Neither continuous nor fullbore, however, can provide a log that is quantitative whenever the fluid velocity is sporadic, that is, changing in the logged interval.

Pressure temperute probe

• Pressure and temperature are logged by the probe in order to use to analyze flow

7

Grammar ray

• Gamma ray logging is a method of measuring naturally occurring gamma radiation to characterize the rock or sediment in a borehole or drill hole. Different types of rock emit different amounts and different spectra of natural gamma radiation. In particular, shales usually emit more gamma rays than other sedimentary rocks, such as sandstone, gypsum, salt, coal, dolomite, or limestone because radioactive potassium is a common component in their clay content, and because the cation exchange capacity of clay causes them to absorb uranium and thorium. This difference in radioactivity between shales and sandstones/carbonate rocks allows the gamma tool to distinguish between shales and non-shales.

The casing-collar locator • CCL allows depth correlation of a cased-hole logging

run • Principle The tool comprises a coil-and-magnet

arrangement with a downhole amplifier. The most sensitive of these arrangements is two like-facing magnetic poles positioned on either side of a central coil. The magnetic lines of flux are distorted when the tool passes a location at which the metallic casing is enlarged by a collar. This distortion gives rise to a classical change in the magnetic field around the conducting coil, within which current is induced. The signal is amplified and recorded at the surface in the form of a voltage spike known as a collar "kick."

Tuning folk

• Tuning folk is measure density of fluid,  then the density can be used to break out the light phase (gas) from the heavy (water/oil/condensate)

10

Capacitant

• Fluid capacitance logging is used to distinguish the mix of water and hydrocarbons in the wellbore fluid.

11

Memory module

• Memory module used to store all data during logging and provide data connection to computer after finish the job

12

MPLT Operation

• Simulation run• MPLT flowing condition• MPLT shut in condition

13

MPLT Operation

• Pre job calibration– Capacitant (for compare with post

cailbrate)– Tuning folk• Air -0,000 to 0.002 g/cm^3• Water 1 to 2 g/cm^3

14

MPLT Operation without patch

15

MPLT Operation with patch

• Need to shut in well across the patch and slowly move through preventing tool stuck

16

MPLT Operation

• Pre job calibration– Capacitant • Air - comparing with pre-calibration not

different than 5 kHz• Water - comparing with pre-calibration not

different than 15 kHz– Tuning folk• Air -0,000 to 0.002 g/cm^3• Water 1 to 2 g/cm^3• Compare with pre-calibration not different

than 0.5 g/cc
