Embodiment approach 1

[0058] Embodiment 1: A method for automatically performing a sweep operation in a borehole penetrating a formation, the method comprising: conveying a drill string through the borehole, the drill string having one or more sensors located thereon determining that a sweep operation should be performed based on information obtained from the one or more sensors; determining characteristics of the pellet to be used in the sweep operation based on information obtained from the one or more sensors; according to the determined preparing a pellet; deploying the pellet into the drill string and delivering the pellet into the drill string; and monitoring the sweep operation while the pellet is in the drill string and verifying the A sweep operation, wherein at least one of said determining that a sweep operation should be performed, said determining said pellet characteristic, or said preparing said pellet is performed automatically.

Embodiment approach 2

[0059] Embodiment 2: The method of Embodiment 1, wherein the characteristic of the pellet comprises at least one of viscosity, density, or size of the pellet.

Embodiment approach 3

[0060] Embodiment 3: The method of any one of the preceding embodiments, further comprising determining what Sweep operation can be performed when .

Abstract

A method and system for automatically performing a sweep operation in a borehole penetrating an earth formation are provided. The method including conveying a drillstring through a borehole, the drillstring having one or more sensors located thereon, determining that a sweep operation should be performed based on information obtained from the one or more sensors, determining characteristics of a pill to be used for a sweep operation based on information obtained from the one or more sensors, preparing a pill in accordance with the determined characteristics, deploying the pill into the drillstring and conveying the pill through the drillstring, and monitoring the sweep operation while the pill is within the drillstring and verifying the sweep operation. At least one of the determination that a sweep operation should be performed, the determination of the pill characteristics, or the preparation of the pill is performed automatically.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Application No. 15 / 135833, filed April 22, 2016, which is hereby incorporated by reference in its entirety. Background technique [0003] Drilling operations are performed in recovering material or substances from an earth formation. During drilling operations, the annulus between the tubing and the borehole may become clogged or otherwise impacted by cuttings, and cleaning operations may need to be performed. Such cleaning operations (eg, hole cleaning) may be referred to as sweeping or sweeping / pelleting operations, where a high-viscosity "pellet" is mixed, circulated down the interior of the drill string, through the bottom hole assembly, and then back up through the borehole ring space. Such operations are often time consuming and require multiple operators and / or personnel to control and monitor many different aspects of downhole operations and the systems associated there...
