Drilling Equipment A drilling rig contain 5 main systems: Hoisting system and Draw works Rotary system Circulation system Power system safety and blow out prevention system Illustration of simplified derrick with equipment including top drive, draw works, drillers cabin and iron roughneck . Hoisting system and Draw works The main purpose of the lifting system and the draw worsk is lifting and lowering the drill string and carrying the weight of the drill string and the casing. The derrick The lifting equipment and machinery The derrick The main purpose of the derrick is to support the travelling blocks and the drill line. The derrick also carries the weight of the drill string and the casing. Two main types: Four legged derrick Mast type Oil and gas drilling derricks are manufactured in various heights spanning from 25 m – 60 m (80 – 190 ft) Derricks in the lower range, 25 m – 35 m (80 – 110 ft) are primarily used for well workover activities. A drilling derrick have to withstand two types of load; compression load and wind load, If the derrick is located on an offshore floating drilling rigs it also woll have to withstand dynamic loads caused by wave motion. Draw works The main function of the draw works is to transfer power to the drill line, the sand line and the “cat heads”. The machinery for an offshore rig would be around 2300 KW (3000hp). Main components of the draw work: Frame Engine Transmission Hoisting drum brakes The draw works have two independent brake systems. mechanical electromagnetic Hoisting system The main purpose of the hoisting system is to lift and lower equipment into or out of the well and to lift the drill string during drilling. For offshore drilling the cerified lifting load would be in the range of 700 – 900 tons. Travelling block The travelling block is connecting the hook and the drill line. The travelling block normally typically has 3 – 7 sheaves with a diameter of 5 – 11 inches. Crown block The crown block is the stationary end of the block and tackle, typically having 7 -10 sheaves. Heave compensator ( offshoredrilling) For ogffshore drilling from a floating drilling rig it is also necessary to have heave compensation to eliminate vertical forces from wabe movement. Guide dolly The guide dolly, a frame with rollers fixed to the travelling block and rails fixed to the derrick eliminates horizontal movement of the travelling block.

Let's delve into the fascinating world of drawworks on drilling rigs. 🛢️ Drawworks are critical components in the oil and gas industry, specifically on drilling rigs. Here's what you need to know: 1.

Let's explore well completions and tubing operations. Once a well has been drilled to total depth (TD), evaluated, cased, and cemented, engineers complete it by inserting equipment designed to optimize production into the hole. Here are the key steps involved: 1. Casing and Cementing: - After formation evaluation (FE) using open-hole logs, steel casing is run in the borehole, and cement is pumped behind it. - Engineers displace the drilling mud with a completion fluid (clear fluid or brine). - Cementing prevents communication between producing zones, ensuring a proper cement sheath between the casing and borehole wall. 2. Perforation: - Engineers perforate through the casing and cement sheath into favorable hydrocarbon flow zones. - Perforations are holes made in the casing using shaped charges fired from perforating guns. - Debris from perforations may be dissolved using a weak acid solution. 3. Tubing Installation: - Tubing transports oil and gas from deep in the well to the surface. - It has a smaller diameter than casing and is installed after perforation. - Pumps are often used to bring fluids to the surface through the tubing. 4. Tripping Pipe: - When introducing tubing into the well (tripping in), pressure is generated at the well's bottom. - The well's fluid ascends to exit the volume encroached upon by the tubing. Remember that the decision to case and cement a well for production or plug and abandon it as a dry hole relies heavily on formation evaluation. Completion engineers aim to recover as much of the original oil in place (OOIP) as possible while ensuring safety and efficient production¹.
