Drilling is the operation of producing circular hole in the work-piece PPT Presentation Summary : Drilling is the operation of producing circular hole in the work-piece by using a rotating cutter called DRILL. Rotary drilling rigs are used for most drilling operations today. The hole is drilled by rotating a bit and applying a downward force. Gene drilling of the prospect or to Farmout. • Landman tries to negotiate the best JOA • JOA dictates the procedures for all operations of the well from the time of full execution • AFE (Authorization for Expenditures) Each partner signs and AFE with commits his company to the payment of the estimated expense sent out on the document. INTRODUCTION Def: Drilling rig may be thought of as a factory or a manufacturing plant, and it is used to drill oil wells, and natural gas extraction wells. The rig is transitory, so it must be moved frequently – that’s why the rig differs from other manufacturing facilities.

Drilling is the operation of producing circular hole in the work-piece PPT Presentation Summary : Drilling is the operation of producing circular hole in the work-piece by using a rotating cutter called DRILL. Aspen Ideas Festival, 2010. Joe Leimkuhler and John Hollowell give a visual presentation about how we drill for oil and the precautions taken along the way. Speakers: John Hollowell, Joe In the operations module, the course provides an overview of the production of oil and gas, from initial exploration to final transport. The second module focuses on the forces that drive the industry's operations, the oil and gas markets, including the cost of wells, seasonal impacts on prices, and the role of oil reserves. The concept of the overall drilling process is relatively simple. There is a potential reservoir located deep beneath the earth’s surface. In order to gain access and extract oil or gas, a hole must be drilled through the various rocks, materials and layers to reach it. In oil and gas drilling, Apply the latest HSE protective measures in drilling operations, well completion, well stimulation, work over and intervention. Recognize tubing pressure losses of different rock & fluid properties and corrosion/erosion potential. Correctly set and operate casings, tubing’s and well head equipment. Health issues related to drilling operations can include industrial hygiene issues related to onsite conditions and may include exposures to drilling fluid components such as oil-base mud fumes and skin contact, highly toxic completion brines, or oils, gas, and toxic materials such as hydrogen sulfide originating from the well. Naturally occurring radioactive materials (NORM) can also be encountered during workover operations, and metals such as mercury are encountered periodically in gas Safety Hazards Associated with Oil and Gas Extraction Activities. Oil and gas well drilling and servicing activities involve many different types of equipment and materials. Recognizing and controlling hazards is critical to preventing injuries and deaths. Several of these hazards are highlighted below.

During drilling operations, this load usually consists of the weight of the drillpipe, drill collars and drill bit. The drill line passes from the drawworks to the top of the derrick. From here is sheaved between the crown block and traveling block to give an eight, ten or twelve-line suspension. This slide pack is part of a series of educational material produced by the Oil and Gas Division to provide the Public with information on the production of oil and gas. The IOM3 accepts no responsibility for the contents of this slide pack. Drilling . Drilling is a machining operation for producing round holes in metallic and nonmetallic Materials. The machine used for drilling is called drilling machine as shown in figure. 3. Tool which makes hole is called as drill bit. Drill bit are the tools used to cut away fine shavings material of work piece in a rotational motion. The most Every signed oil well drilling contract includes some form of conditions and agreements. For example, the drilling rig contractor will agree to a specific drilling depth, financial obligations, or where the well will be drilled. Once everything has been agreed upon, the drilling rig will be moved in to prepare for drilling.
