Gas-Lift Troubleshooting

Image
   Gas-Lift Troubleshooting: How to Diagnose Well Issues Before Calling a Rig Gas-lift problems are usually associated with three areas: inlet, outlet, and downhole (Fig. 1). Examples of inlet problems may be the input choke sized too large or too small, fluctuating line pressure, plugged choke, etc. Outlet problems could be high backpressure because of a flowline choke, a closed or partially closed wing or master valve, or a plugged flowline. Downhole problems could include a cutout valve, restrictions in the tubing string, or sand-covered perforations. Further examples of each problem area are included in this handbook. Often the problem can be found Fig. 1: The Gas-Lift System on the surface. If nothing is found on the surface, a check can then be made to determine whether the downhole problems are wellbore problems or equipment problems. Inlet Problems Choke sized too...

Understanding Rock Compressibility in Oil Reservoirs: Key Concepts and Examples Understanding Rock Compressibility in Oil Reservoirs: Key Concepts and Examples In this blog post, we delve into the fascinating world of rock compressibility within oil reservoirs. Let’s explore the critical concepts and practical insights: 1- Sources of Stress and Compaction: Understand the forces at play: overburden pressures , subsurface pressure, and hydrostatic pressure. Explore how these stressors impact rock behavior. 2- Rock Compressibility Types: Rock Matrix Compressibility (𝐶_𝑟): Uncover the intrinsic compressibility of the rock matrix . Rock Bulk Compressibility (𝐶_𝐵): Learn how the entire rock responds to pressure changes. Pore Compressibility (𝐶_𝑃): Dive into the compressibility of pore spaces. 3- Isothermal Compressibility: Discover the significance of isothermal conditions in rock behavior. 4- Formation Compressibility and Total Compressibility: Explore the relationship between form...

Essential Knowledge in Oil and Gas Engineering: Understanding Surface Tension and Capillary Pressure in Reservoir Rocks Essential Knowledge in Oil and Gas Engineering: Understanding Surface Tension and Capillary Pressure in Reservoir Rocks In the field of oil and gas engineering, understanding the properties of reservoir rocks is crucial for effective exploration and production. One of the key topics that students in petroleum engineering must grasp is the concept of surface tension and capillary pressure in reservoir rocks. These phenomena play a significant role in the behavior of fluids within oil reservoirs, influencing how oil, gas, and water interact within the porous media of the rock. In this blog post, I am excited to share an important lecture that delves into these critical concepts. The lecture, titled " Surface Tension and Capillary Pressure in Petroleum Reservoir Rocks," is designed to provide university students, particularly those studying petroleum and gas...
