(2019015) SHOOTING FLUID LEVELS IN CO2 APPLICATIONS

In 2014 Oxy EOR had lost confidence in the accuracy of Fluid Levels in CO2 wells and was not shooting them. Echometer and Oxy collaborated to identify the root cause of the fluid level inaccuracy and resolve the issue through improved procedures and educating personnel. Today trusted fluid level information adds value by improved operational decision making.

(2019016) SUCKER ROD GUIDE IMPROVEMENTS

Typically, the Petroleum Industry maintains operational ideas that were developed years ago.  These operational ideas may still have merit, but some improvements should be considered.  Sucker rod guides are an example of such practices.  Most production companies continue to use rod guide material that was introduced at the conception of the recognition of the need for sucker rod guides.  This presentation will give information of new materials and new application ideas for sucker rods guides.

(2019031) UNDERSTANDING CAVITATION ON HYDRAULIC JET PUMPS, A SOLID AND EASY TO IMPLEMENT GUIDELINE TO AVOID AND MITIGATE CAVITATION DAMAGE

The cavitation phenomenon has been extensively studied for many years, however, guidelines on how to implement this existing knowledge to the actual operation of the jet pumping systems in the oilfield are not abundant and, as per the author can see it, not yet being presented in such way that the people that operate these systems in the oilfield could implement on a straight forward way. It has been proven that using a scientific and easy to follow methodology, it is possible to prevent jet pump operating problems related to cavitation, during the early, middle and late stage of the well production life. Preventative and Corrective methodologies are based on: Measured production rates, power fluid rate and pressure, gas to liquid ratio, jet pump seating depth and jet pump nozzle/throat combination.



This paper presents a straight forward discussion on the jet pump cavitation, its hydrodynamics, causes, identification, potential damage, consequences on the jet pump performance and methods to predict it and avoid it.

(2019027) USE OF FACTORS THAT INFLUENCE ESP RUN LIFE

The ESP system is a mechanical/electrical/hydrodynamic system. It is costly when it fails as the tubing has to be pulled and much or all of the equipment is replaced. 

This paper points out tips in the below various areas that if considered are likely to increase the average run life of ESP Systems



-Failure definitions from data

-Design

-Installation

-SCADA-Monitoring

-Tips for running in Harsh Conditions

-Pulling

-Teardown Analysis

-RCFA and follow up

The information summarized includes industry findings and experience from the author’s backgrounds

(2019006) VALIDATION OF FRICTION COEFFICIENT AND WEAR CONCEPTS IN SUCKER ROD LIFT SYSTEMS

In some of today’s unconventional wells, sucker rod pumping systems are facing challenges related to excessive wear, affecting production and increasing operational costs. One of the reoccurring damages in a sucker rod pumped well occurs near the kick-off point in a deviated well between the coupling and the tubing or between the sucker rod and the tubing; the metal-to-metal contact causes hole-in-tubing failures and operators have been seeking solutions to mitigate or minimize excessive tubing wear in highly deviated wells. Wear caused by both metal contact and abrasive particles, as well as corrosive attack from the wellbore’s fluid also affects the metal integrity of the tubing, coupling and sucker rod. It is beneficial to develop fundamental understanding on wear and friction concepts in rod lift applications, to optimize rod lift product designs and improve Mean Time Between Failures (MTBF) in deviated wells.



In this paper, the concepts of friction and wear will be explained from applied rod lift engineering perspective. Field tested solutions to reduce tubing wear will be presented with lab and field data.
