The fact that geothermal energy has a great role to play in electricity generation is enough to justify the need for having more geothermal wells. For those who are new to this, geothermal well drilling follows the same approach as oil and gas drilling, except for the fact that it needs to be adapted for a comparatively higher temperature and larger well diameters. Geothermal drilling equipment usually consist of a drill pipe, drill bit, drilling fluid, drill rig, and power system. A drill pipe is typically used for transferring drilling fluid from mud pit to the ground below. It is also used to rotate the drill bit which does the real cutting of the surface. There are a couple types of drill bits available. Selecting the right geothermal drill bits is an important part of drilling and is usually documented for future references. The role of drill fluid, flowing through the pipe, is to promptly bring up the cuttings from the base so that the rocks don't encumber the drilling proce

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

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

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

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
