Milling Casing Effectively

7.1 Introduction 7.2 General - My-Spread Forum

Casing Milling is the term given to milling substantial, long sections of casing, following retrieval of the un-cemented casing string above the cut point. This has been performed typically on platform wells, where the existing well has been abandoned, across the reservoir.

Milling technique a critical first decision in re-entry drilling When special sizes and debris eliminate washover options, sidetracking from a whipstock can be the most cost effective means to reach the target. During the late 1980s, the buzz word around drilling departments was horizontal. In the 1990s, the hot item is multilaterals.

Chapter 17: Section Milling - The Guide to Oilwell Fishing ...

Section milling and pilot milling are similar in that both operations mill away large sections of casing or pipe, but they are not the same. Section milling creates an exit point in a string of casing that is equal to the bit size of the casing being milled. Pilot milling completely removes an entire casing string from the top to the point where milling stops. The resulting hole is larger than ...

Grain Processing - an overview ScienceDirect Topics

Modern milling processes can effectively achieve contaminant redistribution in the flour and by-products produced. This is achieved at two levels. Prior to milling, grain is ‘cleaned’ (Fig. 15.4) by the physical removal of extraneous matter and sub-standard grains. Cleaned grain may also be subject to further ‘cleaning’ by the removal of surface bran layers by pearling or scouring. A ...
