Relocation exploration plays an important role in the oil and gas today mainly because the demand for oil and gas are increasing worldwide.
How does it work
To find the natural gas or oil, oil companies invest millions in drilling equipment all exploration efforts did not yield positive results. Geologists also used to study the area, check the soil gas sampling and testing. To locate traps oil, geologists can employ the use of different equipment which is magnetic survey equipment. This device works by mapping magnetic anomalies that may show signs of oil traps. Another is the use of seismic data or sparks which involves the use of shock waves. As the shock waves are sent to the ocean floor, geological studies were retrieved from rocks that have been affected by the shock waves.
As the possibilities are narrowed, geologists study the geography, topography and climate, assessment of the basic conditions for drilling. They also complete its preliminary exploration with ground penetrating radar, estimating the size and volume of groundwater reserves. Using a variety of sophisticated tools and 3D imaging devices, each map explorers finally promising site in three dimensions, thereafter plotting the route ideal for drilling.
Experts say that a reservation must contain at least 160 million battles over oil exploration and drilling penalty. To determine the viability of a site can take up to three years and cost millions of dollars.
The paper map can draw a perfect path to the “hole”, but the bit often cut directly into the rock under the influence of gravity. Downhole drilling a well is not progressing as simply drop a plumb line from a memory, because resistant solid rock drilling drill fairing can send in ground oblique angles dramatically; or solid rocks can simply break the holes. Because the observer can not simply look down into the hole to secure the drill remained constant in the course, drillers their wells tested regularly and continue to test the rocks and sediments that confers hole.
Most drillers employ Wireline to control and guide the drilling process because Wireline control has highly specialized instruments for monitoring and adjusting the path and size of the perforation. Besides keeping track Wireline measure the temperature and pressure of the well drilled under the crust of the Earth, helping drillers to suit different types of resistance and help developers to anticipate the needs of pumping oil out of the hole.
Traditional soil-gas sampling methods
Advantages of traditional methods include:
unique patented design reduces the potential for leaks during sample collection, improving sample quality;
built-in disposable seal eliminates the need for grout, increasing productivity;
connects easily to sampling equipment;
easily installed, sampled, and retrieved for reuse;
reduces damage to the slab;
improves diagnostic testing;
improves spatial resolution;
reduces sampling time allowing collection of more samples for less cost, and thus provides a better understanding of site conditions.
