Oil well drilling process ppt
An oil or gas well is drilled in a very ordered sequence. The steps in this sequence are almost universally applied to the drilling of all wells.

The first oilwell in the U.S. was a 69-foot hole drilled by Edwin Drake in OF OILWELL DRILLING • Well completion is the process of setting casing and COURSE CONTENTS. ▫ Introduction. ▫ Types of Oil Rigs. ▫ Rotary Drilling. ▫ Well Control. ▫ Drilling Procedure. ▫ Directional Drilling. ▫ Drilling Problems Jun 28, 2014 drilling process basics.ppt - Free download as Powerpoint whether or not to complete a well (if there is oil), or abandon it (if theres no oil). Directional and Horizontal Drilling in Oil and Gas Wells This method has been used to reduce the surface footprint of a drilling operation. In 2010, the
An Introduction to Oil & Gas Drilling and Well Operations Drilling a well is the only way to access a Reservoir and establish what “lies beneath”. Each well is a multi million pound project involving multi An Introduction to Oil & Gas Drilling and Well Operations
The upstream oil and gas process . drilling of the first commercial oil well. exploration data, and will only drill when models give a good indication of. The drilling process complex as it may be rotate about breaking the ground and lifting the The PDC bits are used in 5% of the drilling cases in the oil industry. DRILLING TECHNOLOGY It is a science of standard methods or techniques which are used / employed for drilling an oil or gas well. 20. DRILLING TECHNOLOGIES Mud Casing Rig Hydraulics Bit Drilling Cementing Special (Directional, Complications, Fishing etc.) Well Control 21. DRILLING OPERATIONS Operations involved in drilling a well are : Rig Building Spudding-In of the Well Drilling (1st, 2nd, 3rd Phase) Logging Casing Lowering 22. The technique is applied to the drilling of relief wells so that mud may be pumped into the reservoir of the uncontrolled well. HORIZONTAL WELL Horizontal well may be defined as an extension of highly deviated wells, drilled in order to situate a drain of considerable length at a precise depth in a reservoir with an angle of inclination approaching 90o from vertical.
The process of modern oil & gas extraction involves many steps - from directional drilling to well stimulation. Here we describe the process in more detail.
Rotary Wells Usually Drilled with. Tricone Bits. • The tricone bit was developed by Hughes Tool Co. in 1933 to drill deeper oil wells. It has been refined many Oil and gas well drilling and servicing activities involve many different types of and equipment, vehicle operation at the well site, and all-terrain vehicles and All wells that are drilled to discover hydrocarbons are called 'exploration' wells, commonly known by drillers as 'wildcats'. The location of a drill site depends on the

Mar 3, 2016 In the early days of the oil industry, drilling wells was a simple operation. A well location was picked at top reservoir, and the well was drilled
The process of modern oil & gas extraction involves many steps - from directional drilling to well stimulation. Here we describe the process in more detail.
The technique is applied to the drilling of relief wells so that mud may be pumped into the reservoir of the uncontrolled well. HORIZONTAL WELL Horizontal well may be defined as an extension of highly deviated wells, drilled in order to situate a drain of considerable length at a precise depth in a reservoir with an angle of inclination approaching 90o from vertical. 3 Well is drilled in several stages. Normally starts with drilling a hole of 30 to 36 inches diameters (76 - 91 cm) down to a depth of 150 to 250 m. A steel pipe called casing is lowered into the well and cemented to the wall. After the cement has hardened, drilling is resumed with a smaller drill bit. At a certain depth the drilling is stopped and another string of casing is set and cemented. This procedure will be repeated for each string until the well has reached the depth of the Drilling Mud Drilling fluid, known as mud, has several different functions essential to drilling an oil or gas well, including – Subsurface pressure control – Cuttings removal and transport to the surface – Suspend solids – Helps suspends weight of the drillstring and casing – Lubrication & cooling of the drillstring & bit
