Data is generally expected to continue its exponential growth the next five to ten years. However, it is commonly agreed that the amount of data that currently exist is abundant and that there is still much to achieve with it. The industry, in general, has recognized both the growth and the need to analyze the data. This is also the case with oil well drilling operations. Currently, operators m...

Oil and gas well drilling activities are associated with numerous hazards which have the potential to cause injury or harm for people, property and the environment. These hazards are also a threat for the reputation of drilling companies. To prevent accidents and undesired events in drilling operations it is essential to identify, evaluate, assess and control the attendant risks. In this work, ...

a r t i c l e i n f o In many mining, civil, and petroleum engineering applications diamond bit drilling is widely used due to high penetration rate, core recovery and its ability to drill with less deviation. Recently, many research have been conducted to estimate the penetration rate of diamond drilling which can be considered as one of the most important parameters in project planning and co...

Directional drilling has evolved over the last few decades to become standard operational practice in the oil and gas exploration industry. One method of steering utilizes a technique known as magnetic Measurement While Drilling (MWD). Vector measurements of geomagnetic fields along a well-bore are used to determine it orientation. This method is advantageous in that it is inexpensive and effic...

in this paper, the results of surface and ground water quality monitoring during drilling of three deep exploratory wells in geothermal project in north west of sabalan in meshkinshahr are analyzed. the region has been investigated by various researchers to generate electricity using geothermal energy. drilling in deep geothermal projects, a variety of materials such as cement, bentonite, barit...

Previous economic analyses focused on relationships between crude oil and natural gas markets centered primarily on demand-side considerations. We provide evidence that two important supply-side connections play important roles in understanding crude oil and natural gas market integration. First, crude oil production and natural gas production require a common capital input: rotary drilling rig...
