FIS Fluid and Debris Isolation Sub. Enhanced operation. The fluid/debris isolation sub is an enhancement of the standard cone-type debris-circulating sub for heavy mud environments or large amounts of debris. The circulation slots are longer to allow a larger amount of relatively large debris to fall out rather than accumulate on the ceramic disc. Side-entry sub - Schlumberger Technology Corporation The lower cover plate 60 may also be seen in FIGS. 1 and 2 and provides working protection to the sheave wheel 16 as the side entry sub moves up and down a cased borehole during a logging operation. FIG. 5 is a cross-section illustration of the side-entry sub taken along lines 5--5 through the threaded nut and the guide 66 of FIG. 1. J slot - Schlumberger Oilfield Glossary Most conventional downhole tools operate by upward or downward movement, rotation, or a combination of both. The J-slot profile creates the track for an actuating cam or pin that combines rotation and up or down movement to provide a simple yet reliable means of tool activation.

The debris is carried up the tool-string annulus in the circulation fluid. An indented profile creating a larger annular area causes the fluid flow rate to drop and allows debris to drop into a basket or receptacle located at the base of the tool.

Slot-check dam system is commonly used to control sediment transport associated with debris ows and mitigate debris ow hazards. This paper aims to estimate the per-formance of the slot-check dam system in the eld and set up a verication to evaluate 5 the e ciency of a slot-check dam system and each subsystem in debris ow sediment control. Wireline Service Tools - Forum Energy Technologies type debris become lodged on top of the dogs of a lock mandrel, etc. The Hydrostatic Bailer is made of a cylinder, about 5 feet long, with a shear disc mechanism at the bottom. The cylinder is at atmospheric pressure, sealed off from well pressure with an O-ring. When the obstruction is reached, the disc is sheared by downward jarring.
