What is PLT in oil industry?
What is PLT in oil industry?
1. n. [Production Testing] Abbreviation for production logging tool.
What is production logging tool?
Production logs are used to evaluate fluid production and movement both inside and outside of the casing downhole. The production logging tools are small in diameter and are run through tubing for evaluation of the well as it is producing.
What is open hole logging?
Open-hole logging refers to logging operations that are performed on a well before the wellbore has been cased and cemented. In other words, the logging is done through the bare rock sides of the formation.
Why do we use production logging?
Production logs are used to allocate production on a zone by zone basis and also to diagnose production problems such as leaks or cross flow. These various tasks can be split between those where the target production is into or out of the well and those where the flow never enters the well, typically flow behind pipe.
What is a temperature log?
A record of the temperature gradient in a well. The temperature log is interpreted by looking for anomalies, or departures, from the reference gradient. Since temperature takes time to dissipate, a temperature log tends to reflect the behavior of a well over a longer time period than other measurements.
What is well coring?
Oil well coring is a procedure that is meant to remove a small amount of rock sample from within the oil well. This entails using a core bit to drill and remove a cylindrical sample of the rock.
What is bore log?
A record, made by the driller or geologist, of the rocks penetrated in the borehole. In the laboratory, a more detailed log is prepared giving particulars relating to lithology, paleontology, water analysis, etc. See Also: electric log, well log.
What are temperature logs in ship?
A temperature data logger, also called temperature monitor, is a portable measurement instrument that is capable of autonomously recording temperature over a defined period of time.
What is sponge core?
Sponge coring is a sponge sleeve modification to a conventional core barrel. This sponge sleeve or liner modification of the inner core barrel is made of a tough porous polyurethane sponge which is preferentially oil wet.
What is core plug in drilling?
The Core Plug Drill is used to cut smaller core specimens from whole cores, blocks, or other media taken from the well bore. We provide a variety of core drill bits, which allows the user to prepare core specimens varying from 0.75″ to 2″ in diameter.
What is logging in hydrology?
Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole. Some types of geophysical well logs can be done during any phase of a well’s history: drilling, completing, producing, or abandoning.
What is a temp tail?
Thermal tails are an effect found in amplifiers, typically in op-amps, emitter-followers, and differential pairs. The effect is to cause a slow drift from ideal of the output of the amplifier from ideal over time. The cause is the mismatch of temperature of the different transistors on the substrate.
