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 […]

Liner hangers and liner top packers to improve completion well construction design and operations As the name suggests, secures and supports the liner. It uses mechanical slips to grip the inside of the casing a pre-determined distance above the casing shoe. The space between the liner hanger and the casing shoe is called the liner […]

The concept of drilling and casing the hole in the same time is, of course, valuable by combining two time consuming processes. So the main purpose of Casing Drilling, or Casing while Drilling (CwD), is to eliminate classic casing runs and isolate formations while drilling. By using Standard casing string instead of conventional drill string, […]

Casing is a significant component of the oil and gas well drilling process. It is used to protect the wellbore from collapsing, to prevent fluid migration between rock formations, and to provide a stable platform for drilling. Casing is generally made of steel and is run into the wellbore and cemented in place. Different types […]

What is Stuck Pipe? Stuck pipe occurs when the drill pipe, drill string, or casing becomes immovable in the wellbore. This can prevent further progress in drilling, and if unresolved, it may require costly interventions or even abandonment of the well. Types of Stuck Pipe 1. Differential Sticking Cause: Occurs when part of the drill […]

Before talking about workover operations it is important to remember the life cycle of a well, planning, drilling, completion, production, intervention, workover and abandonment. According to my experience the workover operations every day it becomes more important within the oil and gas sector isn’t only for its several activities Isn’t also for its economic compared […]
