Drilling and boring are two basic types for extracting oil and gas from the earth’s surface. If you plan on working for the oil and gas industry in your career, then you must understand their methods and how they operate. Drilling and boring are two methods but have many types; some are advanced and cost …
Drawworks Brake System can be divided into: MAIN BRAKES (STATIONARY BRAKES) The main brake of a drilling rig is the mechanical band brake or the hydraulic/ mechanical disk brake system. As the name implies, the primary method of stopping the draw-works drum is by the use of the main brake. It is, therefore, essential that …
The only way to obtain information, before well drilling, on the nature and characteristics of the subsurface, including the pore pressure prediction, is through geophysical prospecting. The seismic reflection method is the most important and extensively used geophysical method for oil prospecting. Although geophysicists and geologists use seismograms mainly for subsurface structural and lithological interpretation, …
Background gas enters the mud circulating system as the formation is drilled by the drilling bit and usually maintains a steady but low level. Additionally, as shales are circulated up the hole, the reduction in pressure explodes the shale particles releasing gas into the drilling mud. These are the most common sources of gas. Pressure …
Oil & gas blind drilling is the process of drilling at the minimum possible pump rate to conserve drilling fluid stocks while the annulus is topped up with water. If returns begin while drilling, this might indicate that the circulation loss zone has been plugged with drilled cuttings. However, it could also indicate the onset …
In general, good operating practice calls for regaining circulation before drilling ahead. However, in some companies, there is one notable exception: mud cap drilling. Mud-cap drilling permits continued drilling despite a pressured formation and a lost-circulation zone in the same interval of the open hole. Although mud-cap drilling has been employed in a limited manner …
In Oil and gas industry, you may search a lot to get advice from an expert. You may use Linkedin groups, Facebook groups, or any social media. But to be sure that you have got the correct answer, it will be difficult on social media. Here comes the drilling forum role. The experience in the …
Subs are short pieces of tubular material used to increase the versatility of the main component of the drilling string. The simplest is a crossover sub, which connects two items with different threads. Others used in the drill string are: Crossover Drilling Sub These are short sections of drill collar material 0.6 m (2 ft) …
We will know from experience that the most challenging physical job on a drilling rig (also check: rig components) is when we are tripping pipe in and out of the hole. We will also know that we count the pipe in and we count the pipe out. The reason for counting the pipe is so …
Offshore drilling is the process of exploring and extracting petroleum products from the rock formation below the seabed. Regarding the subsea drilling program, offshore drilling companies render special equipment, drilling rig components, protective gear, and other essentials required in the extraction and transportation of products. According to the survey, the global offshore drilling market is …
