Everything You Need To Know About PDC Hole Openers

What is a hole opener?

A hole opener can be defined as a fixed diameter bore hole enlargement tool that is used to expand a well bore beyond its original hole size drilled by the bit. Different types of PDC hole openers are used for different applications. These are stable, vibration free, have a longer service life, and there is no fear of losing the cones.

The major function of a PDC hole opener

A PDC hole opener is usually used after the pilot bit has drilled the original hole. It can either have a body with roller cones or it could be a fixed blade that would be dressed with PDC.

Where are these used?

A hole opener is tripped into the well bore to the beginning depth and then utilized to enlarge the pre-drilled pilot hole. This is the most common use of a hole opener, however, they may be also utilized to ensure that the gauge of the pilot hole is intact through a method called a wiper trip. Wiper trips are suited well for deviated holes where trying to run the bit back to the end of the section could actually case a side track scenario in softer formations. Some kinds of hole openers are also utilized in the same drill string as the bit to perform a function of actually enlarging the well bore or ensuring that the bit gauge is maintained and clean up any formation beds that may accumulate throughout the section being drilled.

Some key features of hole openers

A hole opener is one of the most cost effective ways to enlarge a pre-drilled pilot hole or to ensure that the gauge is maintained in a deviated hole. In addition to that, hole openers with a bull nose below helps to mitigate any potential side track issues in wiper trip applications.

Any conversation around oil well drilling bits will be incomplete without a mention of all the factors that affect the performance of a drilling bit. These factors include the condition of the drilling bit, the weight applied to it, and the rate at which it rotates. The importance of drilling fluid for enhancing the performance of a drilling bit is something that cannot be taken for granted either. Before we talk about choosing the right oil well drilling bit, let us take a look at what functions do they serve: . Speedy penetration by choosing the most suitable bit for that particular rock formation . Offer a long working life and minimize trip time The two factors which significantly affect the choice of drill bits and reamers are the type of soil formation to be drilled and the cost of the bit. Choosing the most suitable drill bits for oil gas drilling helps cut down the bit costs and minimize the number of trips required for bit changes. Here, it is important to be brought to your ...

Factors That Influence the Choice of Right Drill Bit

Image
Choosing the right drill bit for any application is of utmost importance in terms of ensuring success and productivity. Other than ground conditions, some other factors that influence the choice of most suitable drill bit have been discussed below. 1. Drill Rig One of the first things that need to be given attention to when choosing the perfect drill bit is the type of drill and its working capacity. When using an old-style drill rig, go ahead with a bit specified for lower RPM. 2. Drilling Expertise If you are still new to the world of drilling and drilling technologies, you should put in extra effort to make sure that the RPM corresponds with the diameter you are using. 3. Knowledge of Area to be Drilled If you have no idea about the area that needs to be drilled, you should start off by taking a look at the previous drilling campaigns that might have been carried out in that area. As a precautionary measure, you may want to go ahead with choosing a drill bit that is suited for a wid...
