-
Single Point Injection Using OrificeProshigher reliability than conventional completion using live valvesmeets zero intervention philosophy set for Chevrons subsea developmentsConsrequires a minimum gas injection rate for well stabilityrequires a higher injection pressurevalve erosion becomes a serious issue
-
The Challenge...Size the downhole orifice as big as possible and we can just control the gas injection rates from the FPSO - general comments heard from various Chevron engineers
THE DOWNHOLE CHOKE (aka orifice) CONTROLS THE RATE OF GAS INJECTION INTO THE TUBING, NOT THE SURFACE CHOKE!!!!!!!!
-
Gas Lift StabilityFor a single point system, there is a minimum surface injection rate required for the orifice to maintain sufficient annular backpressure (i.e. casing pressure consistently higher than the flowing tubing pressure) for continuous downhole gas injection.
-
Minimum Injection RatesThis minimum injection rate is a function of orifice size and flowing tubing pressure (aka wellhead pressure, PI, reservoir pressure, watercut, etc) What does happen at rates lower than this minimum injection rate?
-
The Challenge..If this stability issue exists, then how come I dont see this with my platform wells? - general comments from various Chevron engineersAnswer: Turns out they are not continuously injecting through the orifice. As these platform wells are completed with a conventional design (unloading valves), the well instability is dampened due to multipointing.
-
Predicting Stability Margins with Transient ProgramsOLGA is the primarily tool used within the industry for transient analysis, however it does not look at transient behavior between the surface and downhole injection chokes. DynaLift addresses the gas lift transient issue, but does a poor job of the flowline assessment. Hence, Chevron has to use both programs. Flowline/ Riser stability OLGAGas Lift stability DynaLift

Objectives of Gas lift StudyDetermine orifice size that will allow for stable production between 1.5 - 2.5 MMscfd for the 10 year life of the wellRecommend injection gas rates to minimize erosion and provide approximate time / procedures to unload the well.How will flowline slugging affect well stability?- information first presented at the 2000 Offshore Technology Conference, paper #11874

In order to prevent erosion to the orifice, lets run two of them. Have the upper orifice the operating point and then run a REALLY large unloading orifice below it!- comments made by the reservoir engineering staff working on the projectTHE CHALLENGE ..

*Include plots and raw data of production rate & gas injection pressure versus gas-injection rate for 0,1,2,3,4,5mmscf/d
**Verify optimal operating point i.e. production rate versus gas injection pressure versus gas injection rate
include flowing bottom hole pressure in each case

The above tables should be completed for the optimal pump / motor i.e. all performance parameters assume the same pump / motor
Please define the optimum pump / motor / seal, including number of stages
If necessary two pumps may be identified i.e. a pre and post work-over pump where the latter pump is optimised for high water cut production
For each reservoir pressure case a pump operating envelope should be annotated with pump operating points over well life
Include flowing bottom hole pressure in each case

Good Morning. It's nice to be back home.Chevron is not a huge heavy oil producer but we do have areas that we have operated in for quite some time. The three main areas are Venezuela, Indonesia and California. We do have some heavy stuff in the Brooks area but I thought you have seen past presentations on that so I threw in Hebron for a quick discussion.
In order to squeeze this presentation into 30 minutes, I will focus on operating practices and downhole equipment that is working well for us. I could talk for days on all the things we tried that did not work. If you want to know more details than what is presented here, catch me sometime during the next few days and I will be glad to discuss them with you.
That ends my presentation. Once again, I would like to thank the organizers for letting me present today. Now, iIf there is some equipment or method that you did not see here, chances are it did not work for us or we were unable to get it into country. For those vendors in the audience who have a product that you know is applicable and we have not tried it, catch me during the next few days to talk. Now, does anyone have any questions on what was just presented?
