Pros: Environmentally friendly: water base drilling fluid is biodegradable, which makes it less damaging to the environment compared to other types of drilling fluids. Cost-effective: Water-based drilling fluid is often less expensive than other drilling fluid types, making it an economical option. Easy to manage: Water-based drilling fluid is easier to manage and maintain as compared to other types of drilling fluids. Easy to clean: Wter-based drilling fluid is easily cleaned, which reduces the risk of contamination and helps to maintain the quality of the drilling process. Safe for use ..read more

Drilling fluid, also known as drilling mud, is a crucial component in the oil and gas drilling process. It serves multiple purposes such as maintaining wellbore stability, controlling subsurface pressure, removing cuttings from the wellbore, and cooling and lubricating the drill bit. The importance of drilling fluid cannot be neglected, as it plays a vital role in ensuring the success of a drilling operation. Wellbore Stability is one of the primary functions of drilling fluid. The fluid acts as a barrier between the drilling fluid and the surrounding rock formations, preventing caving and ot ..read more

Drilling rig consists of following systems. Hoisting system Rotary system Circulation System Power system BOP system Monitoring system Drilling Rig Hoisting System It enable drilling rig to raise and lower working string into and out of well bore. main components of drilling rig hoisting system are: draw works, drilling line, crown block, traveling block, mast,dead line anchors and storage spool. Draw works It have a drum on which drilling line is reel in  and out to move travelling block inside mast or derrick for raising and lowering drilling string.  How Drilling rig ..read more

We have following types of mud losses while well drilling on drilling rig.  1-Surface mud  losses  Surface mud losses mean mud loss due to surface equipments like shale shakers, desander, desilter, mud cleaner and centrifuge. Solid control equipment do not discard dry solid, there is limited liquid portion of mud that  is also discharge with cutting or solid. This drilling fluid loss with cutting or solid being exit from solid control equipment is called surface mud or drilling fluid loss.  We can minimize surface  loss of mud on oil and gas well drilling by fo ..read more

Power system is a one of the most important  part  of drilling rig because it is needed to power up all drilling rig systems (rotary, circulating, hoisting, blow out preventer and monitoring systems etc.)Depending on rig horse power, there can be three or four engine Generator set. All these engines run on diesel fuel and mechanical power produced by diesel engine is used to run generator, these generators convert mechanical energy given by diesel engine to electricity. This electricity produced by all these engine generator set is given to power distribution system; power distrib ..read more

Drilling rig operation report also called daily drilling report or DDR contain several acronyms. These acronyms minimize drilling report size and make it easy to read and understand. Without these abbreviation drilling report will look massive text contents and reader will feel boring. Let see some mostly used acronyms in oil and gas drilling rig operational game plan and daily drilling report. DP -Drill pipe HWDP– Heavy weight drill pipe DC– Drill collar BOP– Blow out preventer TDS– Top drive system WOB-Weight on bit ROP– Rate of penetration GPM– Gallon per minutes SPP– stand pipe pre ..read more

There are two drive systems used on rotary drilling rig. These are Kelly drive and top drive system. In this post we will go through of  kelly drive versus top drive system. Top drive system is also known as TDS.    In kelly system, Rotary table provide rotation. Whereas in  TDS, String is rotated with TDS motor. Kelly drive is Cheaper but also slow , inefficient and unsafe. Whereas . Top drive system is Expensive but Fast, efficient, and safe. Kelly drive system is capable to drill with one single drill pipe.  On other hand TDS is capable to drill with drill pipe ..read more

mud tanks are important rig components that are used for storing mud for oil and gas drilling operation. We will discuss about mud tanks miscellaneous components .  Mud Is mixture of water and chemicals used as drilling fluid to drill the well mainly  for removing drilled Cutting and to overcome formation pressure.  Degasser It is located on down stream of shale shaker on mud tankand is used to remove any entrap gas in mud while controlling gas kick AgitatorAre used to agitate mud to prevent settling down of solids from mud.  Mixing HopperUsed to mix ..read more

Oil and gas rotary drilling rig have several tools at rig floor for handling drill string various components. Rig floor is a platform which provide work space for crew member  for tripping drill pipe into or out of wellbore.  Driller’s Console: The control panel, located on the rig floor, where the driller controls drilling operations Rotary drilling rig crew use various tools for handling drilling string while tripping operation.. let see these various rig floor components that provide support for deal with drill string components.  Side door Elevators:  A set ..read more
