In particular, all modern hydrocarbon rotary rigs contain five main systems. These systems are: the Power System. the Hoisting System. the Rotary System. the Circulation System. the Well Control System (Blowout Prevention System) These systems are shown in Figure 9.01.
Rotary System A.Traditional Components • Today, many contractors, especially those offshore, employ top drives on their rigs. • However, many rigs still use the rotary table system to rotate the drill string and bit. • The main components of rotary table system are: Rotary table with turntable Master bushing Kelly drive bushing
A rotary drilling rig, whether on land or offshore, can be thought of as a factory designed to produce only one product—an oilwell, or hole, as it is called in the business.
simple diagram of a rotary rig. Drilling fluids went through major technological evolution, since the first operations performed in the US, using a simple mixture of water and clays, to complex mixtures of various specific organic and inorganic products used nowadays. These products improve
26 kwi 2017 · This chapter discusses the equipment and design criteria used in common water-treatment systems for disposal or injection. In addition to the removal of dispersed or dissolved hydrocarbons and solids, the water-treatment engineer may be concerned with chemical treatment, material selection, and solids disposal, which are also covered.
The move to deepwater locations required placing the blow-out preventer (BOP) on the ocean floor. This “subsea” BOP stack initially used a conventional method for controlling the BOP functions from the MODU. In shallow water and mid-water depths, this is accomplished using a straight hy-draulic system in which hydraulic fluid was pumped down
1 lip 2022 · This is further enhanced by the widely heterogeneous physical and chemical characteristics of OPW, which depend on factors such as hydrocarbon composition, water used for enhanced oil recovery (EOR) operations, geological formation and location of the oilfield.
