Sentence examples for drilling trip from inspiring English sources

The estimation of drilling trip time has a great significance in drilling engineering.

In this work, both an artificial neural networks (ANN) model and a multiple linear regression model have been developed for estimating drilling trip time.

In this study, an attempt is made to develop a model for estimating drilling trip time in the southern Iranian oil fields.

Drilling trip time depends on factors such as: well depth, hole size, surge and swab pressure, bottom hole assembly configuration, hoisting capacity, use of automatic pipe handling system, type of rig, hole problems, crew efficiency, and drilling regulations.

In this study, both a regression model and an ANN model are developed to predict drilling trip time from the predictor variables that are depth, open hole length, drill collar number, bit diameter size, mud weight, using downhole motor, and using top drive rig.

The highest risk activities are associated with, for instance, penetration drilling, the trip in and out, and the hoisting and lifting operations.

In addition to pulling and running drill string, trip time also includes mud circulation before trip out for cleaning the hole and well observation at the bottom hole, casing shoe, and in above of drill collars.

The purpose of this study was to examine operator situation awareness (SA) and associated physiological load, using heart rate and heart rate variability (HRV), during different simulated offshore well control scenarios (drilling and tripping) and criticality levels (failure presented or not).

These problems can be mainly attributed to the drill string tripping and the low strength of coal.

Chaney is trying to run his team through drills when a trip across a tightrope might be more apt.

Ten trained participants completed four scenarios (tripping non-failure, tripping failure, drilling non-failure, and drilling-failure) in an experimental session, lasting ∼6 h.
