There are two main categories of sliding sleeves.
Sliding side door oil and gas.
The durasleeve sliding side door circulating and production sleeve is a full opening device that can be operated using standard slickline methods.
The sliding side door is a pocket in a completion string in offshore oil and gas drilling.
This increases overall productivity and ultimate recovery delaying unwanted water or gas production.
The sliding sleeve is the layer exploitation tools during the well completion in oil gas well.
Solution that reaps large rewards in total oil recovery over the life of the well.
Directional drilling is conceptually simple.
Valves are installed in these pieces of hardware which are an important part of regulating the flow of gas.
Their main uses are to shut off flow from one or more reservoir zones or to regulate pressure between zones.
A sliding sleeve is a standard component for the completion of an oil or gas well.
It incorporates an internal sleeve that when open enables communication between the tubing and tubing casing annulus.
Point the bit in the desired direction.
They are also known as sliding side doors ssd or sliding sleeves and generally contain a nipple profile at the upper end for contingency purposes.
Sliding side door sleeves are a.
Open close sleeves are shifted between a full open position and a closed position.
The sliding mandrel is equipped with balance port to equalize the pressure of the oil and sleeve in order to prevent seal from damage.
Adopt large drift diameter design to provide sufficient flow area.
Side pocket mandrels side pocket mandrels spm are positioned in a completion to provide an injection point for lift gas or chemical inhibitors or provide a circulation facility for well kill purposes.
This device gives you the opportunity to have communication between tubing and the csg annulus.
This pointing is accomplished through the bent sub which has a small angle offset from the axis of the drillstring and a measurement device.
The adjustability of the equiflow icd allows the operator to change pressure drop.
The packoff assembly isolates the sliding sleeve ports and prevents fluid migration between the tubing and casing annulus while allowing restricted flow up the production tubing from below.
