How Oil and Gas Wells are Drilled and Produced
Oil and gas wells are engineered structures that provide a controlled connection between underground hydrocarbon reservoirs and surface facilities. The process of drilling and producing a well involves several stages,…
What Is Artificial Lift? Methods Used in Oil and Gas Production
As the reservoir pressure drops, the natural energy of the production wells may not be sufficient to lift the fluids to the surface at the required rate. At this point,…
What Is Pulsed Neutron Logging? Applications in Cased-Hole Wells
When it is necessary to assess the oil reservoir conditions in a well with a pre-installed casing, pulsed neutron logging (PNL) can provide an effective evaluation method. Unlike conventional open-hole…
How to Choose the Right Wireline for Your Well
Selecting the right wireline is critical for safe and dependable well intervention operations. Wireline is commonly used in activities like well logging, perforating, setting and retrieving downhole tools, production monitoring,…
Snubbing Unit Well Control Simulation: Managing Pressure in Live Well Operations
The snubbing operation of forcibly lowering or raising the pipe string is usually employed for pressure-bearing wells where pressure relief cannot be achieved in advance. During the process of lowering…
Types of Well Intervention: How to Make a Choice
Well intervention is the set of jobs done on an oil or gas well after it is already built. The goal is to bring back output, keep it steady, raise performance,…
Team-Based Well Control Training: Enhancing Communication Between Driller and Company Man
The well control incident may deteriorate rapidly. The driller is usually the first to notice abnormal changes in flow rate, pressure or the volume of the mud pit. Subsequently, the…
How a Petroleum University Uses a Drilling Simulator for Well Control Training?
Students majoring in petroleum engineering may have theoretical knowledge of formation pressure, static water pressure and well control procedures. However, when facing constantly changing well conditions, merely mastering formulas and…
How to Build a Well Control Training Center?
Building an oil well control training center is not simply about purchasing simulators and installing them in classrooms. A practical training center should be combined with training objectives, simulation equipment, instructors,…
Key Technologies for Oil and Gas Drilling in Mature Oilfields
Mature oilfields are basically reservoirs that have been producing oil and gas for quite a few years, and they have already seen major depletion. Even when these fields still hold…
Can Drilling Simulators Replace On-the-Rig Training?
For decades, practical operation of drilling platforms has been an important part of training for drilling personnel. However, if each training stage relies on actual drilling platforms, it is costly,…
Coiled Tubing vs. Conventional Workover for Well Intervention
Well intervention matters a lot for keeping oil and gas output steady. It can also improve well performance and help existing wells last longer. When a well needs help, like maintenance,…
