Gas-Lift Troubleshooting

Image
Troubleshoot your well before you call 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 large .  Check for casing pressure a...

Lecture about Porosity in Reservoir Rocks PPT

Understanding Porosity in Reservoir Rocks Porosity  is a critical rock property in the oil and gas industry. It defines the fraction of a rock’s volume that is occupied by pore space—those tiny voids where fluids (such as oil, gas, and water) can reside. Imagine these pores as the reservoir’s storage compartments, waiting to hold hydrocarbons. Understanding Porosity in Reservoir Rocks The Basics of Porosity 1. Definition:   Porosity quantifies the storage capacity of a rock. It’s the ratio of the pore volume to the total volume (also known as the bulk volume). Mathematically, we express it as:   [ \phi = \frac{{V_p}}{{V_b}} ]   Here: (V_p) represents the pore volume. (V_b) is the bulk rock volume. 2. Types of Porosity: Total Porosity ((\phi_t)): This includes both connected and isolated pores. Connected pores can transmit fluids, while isolated pores cannot. Effective Porosity   ((\phi_e)): Only considers connected pores—the ones that matter for fluid flow....
