Total questions: 11
Worksheet time: 11mins
What is the primary purpose of Production Logging (PLT)?
Directional drilling control
Measure casing thickness
Cement bond evaluation
Determine how much and what type of fluid is flowing in the wellbore
Which sensor in an MPLT tool is used to measure fluid velocity?
Gamma Ray
Spinner
Pressure sensor
Temperature sensor
Which two parameters are commonly measured by MPLT sensors?
Flow rate and fluid type
Resistivity and porosity
Casing corrosion and stress
Lithology and grain size
Which condition should be considered before performing an MPLT survey?
Well flow condition
Wellhead color
Rig availability
Drilling mud weight
Which sensor is primarily used to differentiate fluid types in MPLT?
Gamma Ray
Capacitance / Density sensor
Caliper
CCL
Why is a shut-in survey conducted during an MPLT operation?
To confirm cross-flow information
To clean the wellbore
To increase well production
To establish baseline pressure and temperature
Which sensor is considered the “heart” of an MPLT toolstring?
Gamma Ray
Pressure sensor
Spinner / Flowmeter
Capacitance sensor
Which PLT operation step is performed to ensure wellbore clearance before logging?
Shut-in survey
Pressure build-up
Flow profiling
Drift run
Which well condition is required before running a PLT survey?
The well must be killed
The well must be cased only
The well must flow in a stable manner
The well must be horizontal
Why are PLTs often run to identify water production problems?
Unexpected water can reduce hydrocarbon production
Water increases tubing strength
Water affects surface separator calibration
Water has no impact on production
Which platform is mainly used for accommodation of personnel offshore?
WP (Wellhead Platform)
FP (Flare Platform)
LQ (Living Quarter)
CPP (Central Production Platform)
