What Does proLAB Offer?
RGL’s proLAB offers a three-phase sand control design and testing program (Fig. 1). This program seeks to evaluate SCD designs for PSD variations of a studied field, utilizing improved sand control testing methodologies.
How Does Industry Benefit from proLAB?Based on the results of RGL’s sand control design and testing program, which considers reservoir complexity and fluid parameters, we confidently design an optimum sand control solution for the well.

The following tests are used to examine your well conditions:
HPHT is used with Standalone Completion Testing to mimic the temperature conditions near wellbore. Temperatures can be adjusted at the sand-trap to simulate flashing across the screen.
High Pressure/High Temperature
Near wellbore conditions simulations are used for sand control evaluation. Different types of completions such as standalone screen, gravel-pack, cased and perforated with standalone screen can be used.
Standalone Completion Testing
Testing mimics the erosions at well conditions using different sizes of screen coupons. The setup is specifically designed for assessing the erosion resistivity of screen material under different flow rates and particle hardness.
Screen Erosion Testing
Large-scale flow loops with real casing and tubing sizes provide a thorough understanding of the flow control device and scab liner’s performance.

proLAB Sand Control Evaluation Tests
Near wellbore conditions simulations are used for sand control evaluation. Different types of completions such as standalone screen, gravel-pack, cased and perforated with standalone screen can be used.
Standalone Completion Testing
Linear-flow Sand Control Evaluation (LSCE) testing:
This setup simulates the near wellbore condition for sand control evaluation purposes. It can simulate different types of completions such as: • Standalone screen (Fig. 2a)• Gravel-pack (Fig. 2b)• Cased and perforated wellbore completed
with standalone screen (Fig. 2c)
This large-scale standalone completion testing set-up is a unique equipment for RGL.
Standalone completion testing simulates both injection and production scenarios under multiphase flow condition. Unlike single-slot coupon experiments, testing the large-scale disk coupons and sand packs helps to minimize the size-related errors. Figure 2(a): Regular standalone completion testing.

proLAB Sand Control Evaluation Tests
High-Pressure and High-Temperature (HP/HT) Testing:
Conditions could be considered to better simulate the temperature-related near wellbore phenomena (Fig. 2d).
HPHT is used with Standalone Completion Testing to mimic the temperature conditions near wellbore. Temperatures can be adjusted at the sand-trap to simulate flashing across the screen.
High Pressure/High Temperature
Solvent standalone completion testing:
Solvent injection can be also included in standalone completion testing (Fig. 2e). The solvent is injected along with oil and brine. The temperature at the sand-trap (below the screen), can be adjusted to simulate the flashing across the screen. The solvent assisted in-situ process poses a higher challenge to the SCD due to the potential of solvent flashing in the vicinity of the sand screen.
Modified standalone completion testing for operations that use solvent involves a modified testing protocol, which allows flow of the mixed bitumen solvent at various rates, desired temperatures up to 90⁰C, and controlled backpressure of up to 1,000 kPa. The drop in the backpressure induces the flashing of the solvent in the vicinity of the SCD.

Linear-flow Sand Control Evaluation (LSCE) testing:
Linear-flow Sand Control Evaluation (LSCE) testing set-up has also been modified to simulate the back-flow conditions in injector wells (Fig. 2f).
Figure 2(g): Pressure pulsation testing.
Pressure Pulsation testing:
Another testing set-up is the pressure pulsation (Fig. 2g), which simulates surging and swabbing in oil wells. The gas, oil, and brine are introduced as pulsations in several multi-phase cycles into the cell, which simulates the near wellbore condition. The pressure pulsation testing has been used mainly to compare the performance of different screens under real cyclic pressure changes across the sand control screen over the well’s production history.
The development procedure and results of RGL’s standalone completion testing have been prominently published (SPE-190125-MS, SPE-189766-MS, SPE-189539-MS, SPE-189557-MS, SPE-193697-MS, SPE-189769-MS, SPE- 193375-MS, SPE-184999-MS, SPE-182517-MS, and SPE-180756-MS).

Figure 3: Slurry standalone completion testing rigs.
This test is designed to simulate the near wellbore condition under radial flow condition. Standalone screen (Fig. 4a), cased, and perforated (Fig. 4b) with standalone screen can be simulated with this facility (Fig. 4). Development of the apparatus and testing results were published previously (SPE-199239-MS).

In addition to pre-pack standalone completion testing (Fig. 2), slurry standalone completion testing (Fig. 3) is available through proLAB. Dead-end filtration testing is specifically designed to evaluate the plugging tendency and flow performance of the mesh screens under different flow rates, fluid viscosity, solid concentration, and particle size. Development of the apparatus and testing results were published (SPE-198056-MS).

High-Pressure/HighTtemperature Radial-flow Sand Control Evaluation:
Due to the increasing interest of operators working with High-Pressure/High-Temperature (HP/HT) conditions, a new version of the standalone completion test was designed, as shown in Fig. 5, to meet the requirements of thermal projects.

Wellbore Simulator:
This setup is designed to simulate tubing deployed devices [such as scab liner completion on the tubing (Fig. 7) and nozzles]. The large-scale flow loop with real casing and tubing size provides a thorough understanding of the performance of the tubing deployed devices. The wellbore simulator is a unique equipment, which was developed through a collaboration with a major operator in Canada (SPE-193366-MS).

Nozzle Testing Rig:
This testing apparatus (Fig. 8) is designed to test and characterize nozzle geometries used in FCDs through measurement of pressure loss and discharge coefficients. It can also help the operators to compare the performance of the nozzles with standard contraction geometries for empirical modelling. The loop is capable to experiment single- and multi-phase flow scenarios involving liquid, gas, and emulsions. Test results from this flow-loop could be used for quantitative determination of critical parameters for flow convergence, and chocked flow phenomena.

Screen Erosion Testing
This setup (Fig. 9) is designed to simulate erosion at well condition. Different sizes of screen coupons can be tested in a specifically designed rig for assessing the erosion resistivity of the screen’s material under different flow rates and particle hardness. Tested screen samples are later scanned to measure the eroded surface.

Bulk Scale Testing:
The set-up (Fig. 10) is designed to evaluate the scaling on the screens and joints under HPHT condition. Actual produced water along with hydrocarbons can be used. The test cell can handle up to 50 psi @ 177 °C. The cell volume is 75 L with internal height 30 inch and internal diameter of 14 inch. This standard set-up is designed to test 3 ½ inch test coupons of 1 ft length. However, any type of the screen and joints, which could be safely contained in the cell, can be tested by customization of this equipment.
