Lost circulation can occur while drilling, cementing, completion or work-over operations. The impact of lost circulation varies in severity and likelihood.įrom a holistic approach, a change in mindset is required when it comes to field development. While the challenge is the same, the underlying causes are different. Lost circulation remains a challenge in mature depleted fields as well as exploratory prospects. Lost Circulation, an Old Challenge in Need of New Solutions!
He holds a bachelor's degree in Electronics Engineering Technology and master's degree in Petroleum Engineering, both from Texas A&M University. Anthony currently serves as the chair of the 2020 SPE Artificial Lift Conference and Exhibition-Americas and chairman of the American Petroleum Institute Subcommittee 11 which oversees standards related to artificial lift equipment.

The one idea I would like members to take away from this lecture is how common these measurement errors are and how to recognize and correct them to improve the operation of their rod pumped wells.Īnthony Allison is an Artificial Lift Advisor for Occidental Oil & Gas, where he provides in-house support for the analysis, optimization, and troubleshooting of sucker rod pumps (SRP) globally. This presentation will discuss the variety of instruments used to capture the inputs to a dynamometer card (polished rod load and position), their strengths and weaknesses, how to recognize errors in the input data, and how to correct them.
The accuracy of calculations that depend on the dynamometer data such as rod stress, gearbox torque, structure loading, and rod stress will also be reduced. A poor quality dynamometer card can lead to improper control of the rod pump system. However, the inputs to the dynamometer card are often of questionable accuracy. All of these tools depend on a dynamometer card in order to properly analyze and control a rod pump system. Eventually these tools shifted to the wellsite in the form of rod pump controllers to provide more accurate control of a rod pump system in real-time. Advanced diagnostic tools first started appearing as desktop applications. Here is the screenshot of glmark2 after downgrading the GL_Version to 2.1.Analysis and control of sucker rod pumped (SRP) wells has changed drastically over the past 30+ years. To test your settings, you can either test with Gazebo or use glmark2.
You can use the following command to downgrade the GL_VERSION echo "export SVGA_VGPU10=0" > ~/.bashrc This method will work better and the Gazebo performance will be also good. In this method, we are downgrading the GL_VERSION from 3.3 to GL_VERSION 2.1. The next method is more better than this #2 Workaround: Downgrade the GL_Version I will not recommend this method, because it will reduce the 3D performance in Gazebo. If you do this, 3D performance will be reduced but this issue will go. The first workaround is disabling the 3D Graphics acceleration in VMware. #1 Workaround: Disable Graphics Acceleration in VMWare This test also helps to benchmark the 3D performance of the current guest OS. You can able to find the GL_VERSION as 3.3.

You can install the glmark2 benchmark tool in Ubuntu to test the 3D performance on your Ubuntu guest first.Īfter installing glmark2, run it on the terminal to get the OpenGL version and to get the 3D performance.
The Gazebo simulation will fail to load the simulation. ProblemĪfter installing ROS and Gazebo, and if you are starting your simulation launch file, you may get the following error in the terminal. Here are the details of this issue with a screenshot. If you are working with ROS and Gazebo in the VMWare Workstation Player 15, you may encounter graphics issues while working with the Gazebo simulator. #2 Workaround: Downgrade the GL_Version.#1 Workaround: Disable Graphics Acceleration in VMWare.
