One of the responsibilities of a directional driller is to correctly grade a bit after it has been used in a drilling operation. Grading bit by IADC classification a used bit is important because it determines whether or not the bit can be re-run or a back up is picked up for the 2nd run. […]

Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon), though it also contains some nitrogen, sulfur, and oxygen. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified. Regardless of variations, however, almost all crude oil ranges from 82 to […]

6 1/2″ DC was Fished after getting a Twist Off, and was caught by Overshot. The fishing tools for drilling are the most widely used tool for overhauling oil and water wells. There are many varieties and specifications of fishing tools for drilling. According to the types of falling objects in the well, they can […]

Oil well drilling involves a complex system of equipment and processes designed to penetrate underground formations, extract hydrocarbons, and ensure safe operations. Understanding the key components of a drilling rig is essential for efficient well construction. Key Insights from the Document: Drilling Rig Components – Includes the crown block, traveling block, top drive, and drill […]

A drilling rig derrick hand is responsible for assisting the driller and mud engineer with operations on an oil rig. In this job, you guide the pipe as your team connects it to the drill hole, mix the drilling fluid, or “mud,” and repair and perform maintenance on the rig and associated equipment like the […]

Objectives of Directional Drilling Directional drilling is employed for several reasons, including: Reaching inaccessible reservoirs – Allows drilling under obstacles like cities, lakes, or environmentally sensitive areas. Increasing reservoir contact – Horizontal and multilateral wells maximize exposure to hydrocarbon-bearing formations. Enhancing production efficiency – Enables better drainage of reservoirs and improves recovery factors. Reducing costs […]

The MSCT mechanical sidewall coring tool reliably recovers up to 50 sidewall core samples in a single trip. Optional configurations can recover up to 75 cores or 20 core-catcher samples. Confirmed sample acquisition The real-time display at the logging unit confirms proper tool operation and sample acquisition. The MSCT tool is run in combination with […]

Connecting (drill bit) 10 5/8″, TXD514. BNA 10 5/8″ 514; INSTALLING NOZZLES 6(11/32″) and 2(14/32″), ATF: 0.850 PG2 to continue Drilling rotary steerable. A tool designed to drill directionally with continuous rotation from the surface, eliminating the need to slide a steerable motor. Rotary steerable systems typically are deployed when drilling directional, horizontal, or extended-reach […]

An opening in the rig floor near the rotary table, but between the rotary table and the vee-door, that enables rapid connections while drilling. The mousehole is usually fitted underneath with a length of casing, usually with a bottom. A joint of drillpipe that will be used next in the drilling operation is placed in […]
