What is the difference between open hole and cased hole?
Open-hole logging refers to logging operations that are performed on a well before the wellbore has been cased and cemented. On the other hand, cased-hole logging involves retrieving logging measurements through the well casing, or the metal piping that is inserted into the well during completion operations.
What is a wireline truck?
The Wireline Truck is a completely self contained wireline vehicle with the operator interface cabinet in the forward section. Wireline high tensile steel system in the rear is operated hydraulically through the chassis.
What is a cased hole wireline?
1. n. [Drilling] The portion of the wellbore that has had metal casing placed and cemented to protect the openhole from fluids, pressures, wellbore stability problems, or a combination of these.
Can you run a well log inside a cased well?
These logs were important because they can be used in cased wells (wells with production casing). At first, loggers had to run their tools somehow attached to the drill pipe if the well was not vertical. Modern techniques now permit continuous information at the surface.
What is the main advantage of open hole completion?
Well-Bore Construction (Drilling and Completions) Open-hole completions have the following advantages: the entire pay zone is open to the well-bore; perforating is not required; well can be easily deepened; risk of formation damage from cementing is avoided; and costs are reduced.
Which of the following is a cased hole completion?
In cased hole completions, production casing is run through the entire length of the well, up to the various zones where hydrocarbons can be tapped. This implies significant costs – to procure casings, cement, manpower, and equipment (such as Perforation guns) to stimulate production.
How does a wireline work?
A wireline operator installs cabling that enables a company to lower equipment into a gas or oil well. As a wireline operator, your job duties include designing the project, analyzing data on potential field sites, drilling the holes, and installing the mechanical equipment or cabling rig necessary to fulfill the plan.
How much do wireline operators make?
Wireline Operator Salary
| Annual Salary | Monthly Pay | |
|---|---|---|
| Top Earners | $66,000 | $5,500 |
| 75th Percentile | $53,500 | $4,458 |
| Average | $47,977 | $3,998 |
| 25th Percentile | $37,500 | $3,125 |
What is cased hole completion?
In cased hole completions, production casing is run along the entire length of the well and through the reservoir. The cased hole effectively acts as a control mechanism for safe production of desired hydrocarbons and as a barrier preventing the reintroduction of unwanted fluids, gases, and solids into the wellbore.
What is an oil well logger?
Oil well logging, also known as borehole logging, is a process where specialized instrumentation is inserted into a borehole to determine the properties of the geological formations surrounding the bore. …
