Crude oil is an extremely lucrative commodity, as gasoline is highly in demand throughout the world. It is made from the fossil remains of plants and animals that perished millions of years ago. As the remains sink into the bottom of the sea and start to decompose, layers of sedimentary mud compress them. The decomposed remains will then undergo a chemical process, which converts them into crude oil as well as natural gas. This natural oil and gas are then trapped between rock layers by natural movements and phenomenon within the earth.


Drilling Oil

Oil companies are a very significant part of the industry because of the effort they put in to access and extract this valuable resource, which is energy. Drilling oil is an extremely expensive and complex process. Thus, marketing oil as an energy source is a great business with remarkable profits.

To locate crude oil, you would need the expertise of a geologist. These professionals search the regions that have perfect conditions to trap oil. Geologists are able to measure even the slightest changes in the Earth’s gravitational field. They use this information to determine the flow of oil.

A handful of methods are used to locate oil and gas and one is by using 3D and 4D seismic imaging. It creates shock waves that can penetrate through hidden rock layers. It sends back reflection to the surface where geologists measure and analyze it.

Once an oil trap determined is a prospective supply that could yield substantial profit, the area will be marked. If the drilling site is on land, the position coordinates will be marked by GPS. Buoys will be used to mark the site if it’s over a body of water. When everything is set, drilling can commence.


The Process

Before the oil company starts drilling, they need to acquire permit and drilling rights from the government first. The geologists will have to survey the area and conduct an environmental impact study. If there is no threat to the environment, the company will then set up the drilling platform and equipment. Drilling rigs in Australia are very useful for this industry, making it possible to bore thousands of meters beneath the earth.

If the site is land-based, the preparation for extraction includes clearing of trees and other obstructions. They will build access roads to allow the easy movement of machinery. Drilling would need some water, so water wells will be dug if there is no water supply nearby. If the area is offshore, a platform will be set-up and anchored on the site.

The workers will also need to have reserve pits for the disposal of rock shavings and the mud dug during the drilling, which are later enclosed in plastic to prevent any environmental contamination. When all is set, the drilling rig can start boring and extracting.


Prostate cancer is one of the most rampant and feared illnesses in men. Doctors and scientists continue conducting researches up to this day for further analysis on its causes in order to find its cure. The hormone replacement therapy for men or HRT has somehow been linked to prostate cancer because of previous medical researches around this disease.

HRT has been a prevalent treatment for low testosterone in men. One of the most commonly cited side effects of HRT is increased risk of prostate cancer. In fact, according to some recent research, low testosterone is actually a risk factor for many types of cancer among men.

Theory Explained

The theory that testosterone replacement increases the risk of prostate cancer can be traced back from a research done by a group led by urologist Charles Huggins in the 1940s at the University of Chicago. Based on their experiments performed first on dogs and then on humans, the group came up with a conclusion that prostate cancer was androgen dependent. According to the study, the cancer worsened when testosterone levels were high, but the cancer shrank when the levels were lowered.

Huggins’ theory led to surgical castration, which is the removal of the testicles. This procedure has become the standard treatment for prostate cancer since then. The research of Huggins’ led scientists and doctors to believe for many years that testosterone levels and prostate cancer occurrence are connected. However, the experiments did not test nor prove this in any way. The experiments were also only limited to small numbers of test subjects, so this was not enough to prove the fact.

This is the reason why most, if not all, medical professionals have become skeptical of hormone replacement therapy for men. Most people then fear that getting this treatment could lead to the development of prostate cancer. Many people do not of for HRT despite its benefits.


Recent Researches

In the recent years, more researches are done. Many studies showed that men with low testosterone tend to develop prostate cancer at a higher rate than the average. Other studies also proved that testosterone only caused progression of prostate cancer in men who had been castrated, but this is not the case in men who still produced testosterone naturally. Because of these studies, the association between testosterone and prostate cancer had been re-examined.

Eventually, the medical community began to change its belief and started to embrace hormone replacement therapy for men. New evidences showed that there is no relationship between increased testosterone levels and prostate cancer. Recent studies showed that increasing the levels of testosterone in men who has already prostate cancer caused no further progression of the disease. Furthermore, these recent studies proved that men with lower level of testosterone are actually more at risk of developing prostate cancer than men with higher testosterone.



With evidences abundant, it has now become clear that the relationship between testosterone and prostate cancer was simply a misunderstanding for most of the 20th century. It is also clear that HRT, as a way of supplementing low testosterone levels in men, will not cause or progress the prostate cancer.


If you have an existing chain link fence, chances are you want to get a screen to cover it up for privacy purposes. Fence privacy screens are an easy way to block off a job site, a school campus, a pool area or your home property from curious eyes and trespassers. Not only will a fence screen provide you with the privacy you seek, it will also add appeal to your property.

Fence privacy screens come in a number of different sizes and colors. However, you need to know some important things before you invest on one.


Color Choices

Consider the color of the fence screen so that it blends in or complements the overall design and color scheme of the property. If you choose a mesh privacy screen, the standard colors for mesh are black and green. Black is common in construction companies and factories, while green is much suitable for residences, parks, gardens, and landscaped areas. If you choose panels and slats, you can use wood or metal where you have a variety of color choices too. These materials are great for a residential property. Whether you go by the company’s product or choose a customized color for your fence screening, it all really boils down to aesthetics.



Privacy fence screens are normally installed over the chain-link fencing. Clearly, the main purpose of a chain link fence is to keep people off the property. So, the fence screen serves as nothing more than a visual barrier. You may want to attach the privacy screen to the exterior of the fence to make it more aesthetically pleasing.


Residential Fence Screens

Privacy fence screening is not just for construction sites and other industrial or corporate setting. People also purchase them to achieve privacy in their yards and pool area without having to invest in expensive fencing replacement. You can have your chain link fence covered with a privacy screen for a much affordable price.

Privacy screens are also a great option around swimming pools. Enclosing your pool lets you enjoy swimming or laying out in the sun without attracting attention from strangers and passersby. People cannot see it from the street. As a side note, be sure to check with your local government office before installing privacy screen around your home or company. Some cities require permit and inspection before you can install a privacy screen.
