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.

Everything You Should Know About Oil Well Drilling Bits

Image
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

4 Factors That Lead to the Decline of Drag Bits

Image
A drag bit usually consists of a couple of rigid steel blades which rotate as a single unit to drill through soft to medium formations. Drag bits underwent major transformation until hard facing was introduced to the surface of the blades and the design of fluid passageways improved its performance several folds. Since these bits drill through scraping action, they have high rate of penetration. Even though drag bits have been around for the longest time and were the first bits used in rotary drilling applications across the globe, they lost their importance over time for several reasons. Some of these being: 1. Roller cone drill bits could drill soft formations in a much better way than the drag bits. 2. Since drag bits were designed to work on low WOB, excess WOB would result in excessive torque and thus, lead to bit failure. 3. As drag bits would drill crooked holes, the need for some means of controlling this deviation arose. 4. Drag bits were designed to drill through formations t
