Drill Bits
When most people think of drill bits they think of drill bits they think of the simple tool that can be found in any house or machine shop. The drill bits are relatively simple in design and are typically used for drilling through wood and metals. Most people don’t realize that when companies drill in the earth for oil they also use drill bits. However, the drill bits used in this process are very complicated in nature, not to mention costly. These drill bitts cost on average between $30,000 and $50,000 dollars, but can cost as in the 150,000+ range. Due to the high cost of these bits, it is important for any supply manager working in this industry to have an understanding of how they work and their intended uses. To completely understand the engineering that goes into these bits would probably require someone to have a degree in mechanical or petroleum engineering. However, with some basic understanding of the different kinds of bits and the manufacturing process behind them, it is possible for a supply manager to properly identify and purchase the proper bit for the project he/she is working on.
The intended use of the drill bits is quite easy to understand. Like the drill bits in found in a simple hand drill, all drill bits are intended to make a hole. The major difference being that you are drilling in rock formations and the hole is 5-30 inches in diameter. These are the two main factors in determining which type of drill bit that should be selected. There are many categories and sub categories of drill bits that drill into rock formations. However, in the modern oilfield the most commonly used type of bit is the rotary drill bit. There are two main types or rotary drill bits, drag bits, and rolling cutter bits.
Drag bits are a type of drill bit that uses a fixed cutter blade to drill into a rock formation. Drag bits physically plow or machine cuttings from the bottom of the hole. Unlike rolling cutter bits, drag bits have no moving parts, which decreases the likelihood that unwanted material could be left in the hole. Drag bits can be further broken down into three categories base on the design and the material they are comprised of.
On April 9, 1997, Rig 52 that belonged to Mallard Bay Drilling was towed to a location in the territorial waters of Louisiana, where it drilled a well over two miles deep. After the well was almost complete an explosion occurred killing four of the crew and injuring several others. Seeing that this was a marine casualty in navigable U.S. waters, under existing regulations the United States Coast Guard responded. When the investigation was over the Coast Guard did not find any violations of their regulations and noted it was an uninspected vessel and the operator held an Operator Uninspected Passenger Vessel (OUPV) license. Soon after the incident the Occupational Safety and Health Administration (OSHA) cited Mallard Bay Drilling for violations
In today's global economy, energy is one of the most crucial and sought after commodities. Who supplies it and how much they supply determines how much influence they have over other countries as well as the global economy. This is why hydraulic fracturing is currently such an important and controversial topic in the United States. Hydraulic fracturing, more commonly known as "fracking" or hydrofracturing, is the process of using pressurized liquids to fracture rocks and release hydrocarbons such as shale gas, which burns more efficiently than coal. This booming process of energy production provides a much needed economic boost, creating jobs and providing gas energy for Americans.

Current drilling technology was unable to penetrate the thick rock of southwest Texas and oilmen could only extract the surface layers of oil, unable to tap the vast resources that lay far below. Big Howard came up with the idea for a rolling bit, with 166 cutting edges and invented a method to keep the bit lubricated as it tore away at the rock. Later that year, Big Howard produced a model and went into business with his leasing partner, Walter B. Sharp, forming the Sharp-Hughes Tool Company. Rather than sell the bits to oil drillers, Hughes and Sharp decided to lease the bits out on a job basis, for the tidy sum of $30,000 per well. With no competitor able to duplicate this new technology, Sharp- Hughes Tool possessed a profitable monopoly over oil extraction. So quickly was the invention successful that in late 1908, the partners built a factory on a seventy-acr...
I actually disagree with drilling. We have to look at the bigger picture and think about the long term goals. Bottom line oil is needed to reduce energy prices and U. S. dependence on foreign oil however at what cost. We have to protect the environment and the animal’s writhing in it.
Black & Decker (B&D) is a global manufacturer and the world’s largest producer of power tools, power tool accessories, electric lawn and garden tools, and residential security hardware. The company was a pioneer in innovation and development of power tools and has used that position to build strong brand names that enjoy worldwide recognition. Key Causes for Poor Performance in the Professional-Tradesmen Segment The reason B&D has performed poorly in the professional-tradesmen segment is due to the positioning of the B&D brand in this segment. Poor positioning of the brand has resulted in customer confusion and negatively impacted customer perception of the brand in terms of being a quality product. B&D Performance in the Power Tool Industry Overall Any adjustments to B&D’s strategy in the professional-tradesmen segment must not have an adverse impact on their success in the consumer or professional-industrial segments. Therefore, a thorough understanding of the needs of each segment will be important in building a viable strategy to challenge Makita in the professional-tradesmen segment, while continuing to maintain share in the other two segments. _Consumer _Segment Professional-Tradesmen Segment This category consists of professionals who are buying a product for their own use on a job site. Their livelihood depends on the quality and performance, as well as the reflection on their skills that using a particular tool brings from others on the job site. Since they are purchasing their own tools, this segment needs this high quality performance at a reasonable price. However, since Makita and Milwaukee are both priced higher than B&D and are seeing greater success in this category, tradesmen are clearly willing to pay more for a product they perceive will be more effective for their use. Key needs for this market segment include: Performance and quality - {text:change} does the job needed to be done, doesn’t break down, produces high-quality results and more efficiently gets the job done. Reliability and durability - does the job every time and can be used for an extended period of heavy continual use. Safety Support from the Manufacturer – if the product breaks or performs poorly, access to replacement parts and service will be key in maximizing performance up-time.
We have all been there. We walk into the garage of our mechanic’s shop, taking a quick glance; we see the huge elaborate toolboxes that each mechanic owns. Most of them are from Mac, Matco or Snap-On. Unless you work in the tool industry most people do not realize what the real cost of each of these boxes is.
By Occupational Safety and Health Standards (OSHA) definition any operator of electric or gas welding and cutting equipment is called a "welder" and "welding operator". The standard 29 CFR 1910 Subpart Q which pertains to welding, cutting, and brazing. The standard consists of 5 parts, they include: 1910.251 Definitions, 1910.252 General requirements, 1910.253 Oxygen-fuel gas welding and cutting, 1910.254 Arc welding and cutting, 1910.255 Resistance welding. It is a rather diverse standard covering all aspects of industrial and commercial applications specializing in safety aspects, guidelines, and requirements as well as proper use and operating procedures.
For example, Hydrofracking; What is hydrofracking? Gas industries use hydrofracking to extract natural gases from shale ground in order to power Americans homes. When gas industries hydrofrack, they dig ten-thousand feet into the mantle of the earth and turn perpendicular to the t into shale layers with cement and steel casing to prevent leaks. Then rupture the layer of sediment with high pressures of water, sand and a plethora of chemicals. Once the chemicals are saturated in the crevices of the drill site, they extract the excess fluid and then ship them to market.
Legos are the multi-colored blocks we used as children to build creations that were only limited by our imaginations. I remember adding to my multi-colored plastic sculptor, each block putting me one step closer to the final product. The process would always entail first setting up a strong foundation, and then creating structural support, while always having a plan in the back of my mind. The outcome of which, would tower above me; to think it all began with a single block. In many ways people are similar to Legos. We are the combination of our experiences, each adding to our personas, and shaping how we view the world. Also like Legos, to have a stable and functioning final product it must have a foundation, support and a plan. I was able to establish my foundation in high school.
Oil companies performing exploration and production services belong in the ‘upstream’ area of the business. Upstream oil companies such as Exxon, Shell, and BP, among others, lease the services from ‘service companies’ to perform the actual drilling of the well. Pride International, Halliburton, Baker and BJ are a few major service companies. Pride International performs drilling worldwide, both onshore and offsho...
the closed faced reels have a small peg inside that catches the line and then spins around the top of the spindle. For this design the reel has a plate that can be moved up and down by a dial on the front. This plate is what controls the drag. The advantage of this method is that it allows you to adjust the drag while you are fishing.
