Dual String Gas Lift Optimizations Using Electric Gas Lift
Dr. Ahmed Al Shmakhy, ADNOC

Most of the world’s gas lifted wells are under-optimized as reservoir conditions and fluid composition change over time. GLV changes are required to manage maintain optimal production, that often necessitate well intervention. It is also not easy for operators to make data-driven decisions on a day-to-day basis to assure continually optimized production.

These challenges are further amplified with dual completion strings: fluctuating casing pressure; unpredictable temperatures due to the proximity of the two strings; and inability to individually control the injection rates to each string. The string dedicated to the formation with lower productivity and reservoir pressure tends to “rob” gas from other string so that one string is preferential produced. Production optimization in such cases requires frequent, costly, and risky intervention which presents an opportunity to re-imagine gas lift well design.

ADNOC in collaboration with Silverwell worked to deploy a Digital Intelligent Artificial Lift (DIAL) system, which consists of multiple ported “mandrels” placed at GLV depths. These mandrels are connected to the surface operating system with a single electrical cable. The ports can be selectively opened or closed by sending an electric signal from the surface unit. In addition, pressure and temperature sensors are also placed which help record these parameters in real time.

Such a system enables the choice of depth, injection rate, loading and unloading sequence to be controlled from the surface. Realtime optimization is possible as pressure/temperature data helps draw accurate gradient curves. This system makes gas lift optimization possible in dual gas lift wells.

It has been estimated that this technology delivers a production increase approaching 20% for single completion wells and exceeding 40% for dual-string gas lifted wells. A business case and implementation plan were developed to pilot a dual-string digitally controlled gas lift optimization system.

This presentation, drawing from and updates the work described in SPE-196146-MS, paper will describe, the screening, business case preparation, risk assessment and validation process, conducted prior to implementation of a fully optimized dual string gas lifted well.

9:00 – 9:30
Real time production optimization in conjunction with virtual flowmeter
Bob Okhuijsen, Siemens Energy

Digitalization solutions are often implemented and evaluated as stand alone systems. The true value
of these type of solutions is however revealed in an integrated ecosystem.

This presentation shows the merits and challenges of one remarkable powerful combination: real time
production optimization and a virtual flowmeter.

Troubleshooting Gas Lift Wells Using Simultaneous Acoustic Surveys
 Gustavo Fernandez, Echometer 

The number of Gas Lift systems have increased significantly along with unconventional wells, the need of understanding the performance and troubleshooting Gas Lift systems is now even more relevant for operators. Tubing-casing communication is one of the biggest issues and it can be identified from surface using a simple, quick, safe and effective simultaneous acoustic survey to find holes in tubing or leaky gas lift valves that are above the liquid level. Both wired and wireless acoustic equipment can be used to perform this acoustic analysis. Two guns with microphones are connected to the wellhead, one gun is connected to the tubing and the other gun to the casing-tubing annulus. One of the guns is used to release a pressure wave down the well either through casing or tubing (usually down the tubing) while the microphone on the other gun just listens for possible echoes from tubing-casing pressure communications (tubing holes and/or leaks). Using Wireless acoustic guns, both tubing and casing acoustic signals are recorded simultaneously. Overlaying tubing acoustic traces on top of casing acoustic traces facilitates the detection of pressure communication point(s) and improves the accuracy of its depth determination. This technique and analysis method is mainly applied to troubleshoot Gas Lift wells but it can actually be applied from Plunger lift wells to almost any type of well with casing-tubing configuration, that are not full of liquid.  Analysis of acoustic data along with wellbore schematics, valves design, plus teardown reports will verify the causes of pressure communications identified on various Gas Lift wells.

Intermittent gas lift, the answer to significantly reducing daily gas injection volumes and lease operating costs in low producing volume wells.
A. Stan Logie, Logie Gas Lift Consulting, LLC

How can a company efficiently produce gas lift wells to abandonment rates without using high-capital-expense rod lift? For savvy operators who must reduce operating expenses in these times of financial austerity, a proven and practical solution is Intermittent Gas Lift (IGL). The average installation costs for a 10,000’ well; $8,000.00 on IGL and $150,000.00 on rod lift, so the savings start from the very beginning

Diversity, Equity and Inclusion in Artificial Lift
(
Panel Discussion)

Angel Wileman, SwRI – Moderator
Kimberly Hoyle, Chevron
Charli Matthews, Empowering Brands
Gustavo Fernandez, Echometer

As the global economy grows, so does the diversity within the oil and gas industry. More diverse companies make better business decisions and are more profitable than homogenous companies. The industry has become more diverse through implementing inclusive hiring practices and equitable opportunities for under-represented groups. However, for many people working within the industry, this work has seemingly gone on behind the scenes without much guidance on how the employees can help further DEI. If you’re thinking, “My company talks about DEI all the time, but I don’t really see any lasting change,” or perhaps “I’m just one person, how can I help?” this session will help answer those questions of how you can be an ally and help promote DEI in your workplace. Let’s move from talk to action and make our workplaces more inclusive, attract the best talent, and work together to make those strategic decisions. Panelist: We are seeking panelists who are active in furthering diversity, equity, and inclusion in their workplace. Panelists should feel comfortable discussing real actions that everyday employees can take to create change in our environment.

Overcoming Inefficiencies of Annular Flow in a Hybrid Gas Lift Well
Charles Kubacak, Ovintiv; Eric Hale + Matt Young, Flowco Production Solutions

Flowco engineers partnered with Ovintiv to analyze past production profiles to create a more efficient design for future wells in the same landing zone. This new concept in gas lift design, was engineered to accommodate higher liquid rate initial production, as well as lower rate later life production without the need for a work-over to make the production change. Reservoir data and predicted rates from similar rock were reviewed prior to the solution selection. Deployment of permanent downhole gauges in these systems was critical for accurate measurement of flowing and static bottom hole pressure (BHP) and provided verification of the optimal and efficient point to switch production from annular to tubing flow.

Remotely Operated Gas Lift Valves in Permian Basin Non-Conventional Wells
Johannes Visser, Chevron

We present a review of new gas lift technologies designed to deliver increased production rates when compared to conventional gas lift systems and demonstrate the applicability of these systems in unconventional development wells in the Permian Basin. Ongoing evaluation of these technologies enable maturation thereof and creates the opportunity to combine with integrated production optimization and autonomous operations in the future.

We focus on the comparison between conventional gas lift technologies and the electrically operated gas lift valve technologies based on multiple parameters defining gas lift efficiency.

The results from wells employing electrically operated downhole injection technologies provide a deeper point of injection and conserve surface injection pressure, reducing flowing bottom hole pressure. We present the opportunity to deploy the technology on wells with a range of the inflow performance spectrum in the Permian Basin.

Several Gas Lift indicators were used for efficiency evaluation criteria during the field trials: Depth of injection, multi-pointing elimination or reduction, and properly-sizing injection port to enable gas injection at critical flow. Downhole and surface conditions were continuously and remotely monitored, and included pressure and temperature sensors at each station, both inside and outside of tubing.

We discuss results that demonstrated the benefits of preserving Gas Lift pressure for single point of injection as deep as possible. These results delivered performance increase, reduced uncertainty in diagnostics and well performance analysis and enhanced completion designs that included the remote operated valves.

In conclusion various scenarios and opportunities are presented for the applicability of this technology and how it would enhance artificial lift operations in the Permian. We discuss how the technology opens up enhanced recovery and production acceleration potential, including driving automation thereof.

Gas Lift Valve Open and Closing Behavior Observations Seen While Conducting Dynamic Performance Testing in Accordance With API 19G2 Annex H

Angel Wileman & Russell Burkey, SwRI

Understanding gas lift valve throughput and opening and closing behavior is essential for completion design and optimizing gas lift performance. Gas flow performance testing in accordance with API 19G2 Annex H – Dynamic Performance Testing is an industry-recognized method for gathering these data. One of the required measurements of the standard is the valve opening pressure, both pre- and post- gas flow testing. This presentation investigates the effects of cooling due to gas expansion on the measured valve opening pressure when Dynamic Performance Testing is performed.

1:30 – 2:00
Taking Charge of Flowing Tubing and Injection Pressures to Optimize Gas Lift Wells
Larry Harms & Tom Nations

Surface pressures are VERY important if you want to get the best performance at optimal cost on gas lift wells.
We continue to see engineers and operators taking these as fixed instead of working across discipline boundaries to have the input and collaboration needed to operate gas lift wells optimally.
Examples of how much difference surface pressures make on gas lift well performance and costs will be given along with how to work across the gas lift “natural work team” to optimize pressures.

Electric Gas Lift Using Existing Side Pocket Mandrels – Is It Possible?
Brett Bouldin, Wireless Instrumentation Systems AS

Conventional gas lift valves placed on the exterior of the tubing string to unload and operate well production began use in the oil patch in the 1930s.  In the 1950s, Side Pocket Mandrels were developed to permit valve placement within the tubing so that changes could be made by through-tubing intervention rather than a well workover.  In the 2000s, many proposed to add downhole sensing and flow control to gas lift wells and success has recently been realized with the development of tubing-conveyed valves equipped with an electrical umbilical to the surface.  Like conventional valves, these electric gas lift valves (eGLVs) are placed on the tubing exterior and conveyed into the well during the completion installation.  Most needs for intervention have been eliminated, being ideal for remote and inaccessible areas or in high deviation wells where slickline is not practical. 

8:30 – 9:00
High Pressure/Single Point Gas Lift Applications (Including Hybrid with “Conventional” Gas Lift)
 Tom Nations & Larry Harms 

High pressure/ single point gas lift (HPSPGL) is being applied more and more on unconventional wells because of the advantages it can bring when compared to ESP’s, beam pumps and “conventional” gas lift (CGL) but the applications don’t stop there. Examples of applications on conventional wells and gas wells will be given along with an update on the applications in unconventionals.

Also, details will be presented on how to combine HPSPGL with CGL to get a hybrid which can leverage the strengths of both.

9:00 – 9:30
Logic Based Injection Leads to Quicker, Deeper, Smarter Single Point Injection
 Adam Anderson, Innovex

Gas lift as a form of artificial lift has been the choice of many operators for decades. We will take a dive into the value propositions and operation of a cost-effective and simple system that utilizes two hydraulic control lines, the differential pressure level between those lines and an automated surface control system to selectively open and close valves enabling deeper gas injection and optimal production.

How can we inject deeper, quicker, and smarter?

Electric Gas Lift Valve Flow Loop Testing
Michael Romer, ExxonMobil

A novel electric gas lift valve was tested in a liquid flow loop to establish its performance characteristics, better define its operational envelope, and identify potential design improvements. A custom skid was fabricated that could be used to simulate gas lift unloading operations for unconventional wells. Various tests were conducted for valve characterization (flow, power, leakage) and evaluation of erosion resistance. This presentation will describe the advantages/drawbacks of the tested system as an alternative to conventional gas lift, the experimental facility, the insight gained through testing, and some of the upgrades being considered/implemented to improve the valve system’s performance.

1:00 – 1:30
Shale Plays and Understanding Multipointing Advantages and Disadvantages
Dean Gordon

The choice of gas lift for unconventional shale plays is proving reliable and, in most cases, the lowest lifting cost per barrel when suitably applied. Current horizontal drilling and completion technology have provided many challenges in today’s daily production practices. Starting out as high fluid and gas rates carrying large quantities of frac sand to surface, flush production from shut ins (+- 10,000 ft HZ) and declining reservoir pressures has compelled operators to reevaluate long term lift choices.

Commonly production ranges start between 2000-5000 BLPD with gas rates greater than 2 MMCF day and associated water cuts between 50-100% or what could be called frac fluid recovery while  lifting / producing these rates from 10,000+feet TVD .Applying a design to kick off well initially, allowing to let flow and then operate 1-2 years later when production rates are down to less than 500 BLPD creates  enormous challenges particularly when based off historical industry design procedures. The single biggest deterrent is the unloading practices used by operators.  

What we once knew as “Multi Point” injection was more than likely gas lift intermitting between two or three valves. With today’s gas lift, Multi Point injection is more likely the required injection gas volume being distributed through two valves with no intermitting at all. IPO valve port sizes play a big part and experience has shown some positive results

Understanding valve performance and how it relates to possible multi point injection is vital. A typical temperature swing between static, initial flowing to future flowing temperatures is a gas lift engineers worst nightmare when using N2 charged IPO valves. This temperature range is frequently between 100 F up to 220F for upper valves.

 Smaller ports offer the advantage of less tubing effect / greater casing stability but have a reduced gas passage capacity. Larger ports may pass the required volume but creates the opportunity to reopen a valve above with a large fluid tubing slug. Understanding the IPO valve port sizes and how they play a big part in daily operations has shown some positive results.

Using NODAL programs combined with VPC or other dynamic simulators provides greater simulation of injection gas volume distribution relating to critical velocities.
