Unexplained changes in the readings on the Flow Show and PVT recorders should be investigated promptly. This usually takes the form of a flow check. In other words, They are implemented to guarantee that the well is stable. it should be carried out with the mud pumps off to check the well with Drilling ECD …
This drilling fluid engineer, who is also called a mud engineer, works with any drilling mud (saline, biopolymer, oil-based mud, etc.), monitors compliance with drilling technology using drilling fluids, determines the need for chemical reagents, drilling mud components necessary to fulfill the customer’s planned tasks, controls their distribution and rational use. This article will discuss …
Before discussing drilling parameters, practices, and guidelines for drilling performance optimization, reviewing the basic concepts of Weight Indicator, Torque, and Limits is beneficial. Basic Concepts Of Drilling Parameters Optimization For Oil & Gas Wells Operations Weight Indicator The weight indicator, often referred to as the `Martin Decker‘, is the most essential instrument for the driller …
The device that is run on the bottom of the casing for primary cementing is called a “shoe”. There are four basic types of shoes that run on the casing, a guide shoe, a float shoe, an automatic fill shoe, and a differential fill float shoe. In this article, we will handle both the float …
The choke manifold is an arrangement of valves, fittings, lines, and chokes that provide several flow routes to control the flow of mud, gas, and oil from the annulus during a kick ( Kick warning signs – Causes of kick in drilling). Here you shall learn choke manifold parts, function & IADC recommendations in drilling. …
The Inside BOP (IBOP) as gray valve is a back-pressure type valve (or float valve) that allows stripping operation using drilling kelly / top drive or running drill pipe into the hole without mudflow upward through the valve. It can be stabbed and made up on the drill pipe only at very low flow rates. …
The annular preventer (also called bag type, spherical, or universal preventer) is the most versatile piece of equipment on the BOP stack since it can close around the casing, drill pipe, drill collars, wireline, and even close an open hole. The rubber packing elements of the annular preventers, which allow this flexibility, are also subject …
It was a very important parameter of reservoir absolute permeability in reservoir evaluation and production prediction for log analysts. So, acquiring reservoir absolute permeability information of target intervals was important for the field development planners, especially in tight sandstone gas zones, but it was also a challenge. At present, many methods have been proposed. Many …
A top drive is an essential part of the drilling equipment. It is located on a drilling rig (Check also types of drilling rigs) hoisted on a rig mast or a derrick. The top drive is a combination of electrical and mechanical motor systems. Top drives have a variety of advantages and prove beneficial in …
Yield Point in drilling mud is defined as the measure of the fluid’s initial flow resistance or the calculation of a value required to move the fluid in terms of shear stress. It can also be stated that the yield point is equivalent to the force of attraction between the particles of fluid colliding with …
