Laser Engineering PVT (Pressure-Volume-Temperature) Laboratory is an ISO 9001:2005 and ISO/IEC 17025:2017 certified laboratory that has been in the business of providing fluid characterization and flow assurance solutions in the oil and gas industry for over twenty years. As the first mercury-free PVT laboratory in the West Africa sub-region, we offer a comprehensive range of standard testing services with our state-of-the-art equipment, ensuring quality and timely delivery of jobs. Below is a list of our equipment and services we render.

Hydrocarbon Fluid Sampling

This involves obtaining a representative sample of the formation fluid for PVT analysis or other analysis. Sampling involves the use of specialized cylinders, equipment and tools depending on the type of sampling. Laser Engineering provides both surface and sub-surface sampling services according to best industry practice.

Surface Hydrocarbon Fluid Sampling

For sampling of fluids which are collected at the well head or the production line for one phase flow (rarely), or at the separator (gas and oil). Sufficient samples can be collected for PVT analysis and/or other studies.

  Surface Sampling Process

Sub-surface Hydrocarbon Fluid Sampling

Sub-surface or bottom hole sampling involves capturing reservoir fluid samples in-situ at reservoir conditions. Bottom-Hole sampling tools can be conveyed downhole via the following methods:

• Wireline
• Drill string
• Coiled tubing

This is the best sampling method for heavy oils as it eliminates issues with slow dissolution of gas from the oil. It is also suitable for fluids from reservoirs with hydrocarbon solid deposition tendencies.

Bottom Hole Sampling Equipment

Sample Storage and Handling

Laser Engineering provides a safe and controlled environment for sample storage in compliance with regulations and standards, ensuring that sample is stored safely and handled properly when not in use.

Hydrocarbon Fluid Compositional Analysis

Gas chromatography separates and analysis the components of hydrocarbon mixture based on their boiling points and affinity for stationary phase. This gives the molecular compositions and as well as provide other properties of the fluids. Laser Engineering has Gas Chromatograph equipment for liquid and gas analysis.

Oil and Gas Condensate PVT Studies

PVT study is a very important aspect of oil and gas reservoir management and evaluation. In this studies, the behavior of fluid under different pressure and temperature conditions are determined. Results from this studies provides the physical properties of reservoir fluids, helps calculate the amount of hydrocarbons in place and recoverable reserves and also help to design optimal production strategies. Very important properties provided by the PVT studies are saturation pressure (bubble point pressure for oils and dew point pressure for gas condensate samples), compressibility and viscosity. This is done using high pressure and high temperature PVT Cells. Laser Engineering currently boast of world class PVT cells for these studies one of which is shown below. PVT analysis done include the following:

1. Hydrocarbon Fluid Compositional Analysis
2. Flash Liberation

• Constant Composition Expansion (CCE)

1. Differential Liberation (DL)
2. Constant Volume Depletion (CVD)
3. Separator Test

• Viscosity Test-

At Laser Engineering, our state-of-the-art laboratory and expert team are dedicated to delivering reliable PVT data on hydrocarbon samples ranging from Heavy Oil to Dry Ga. Other major equipment for PVT analysis include recombination system, gas chromatograph, etc. Also, we have equipment for measuring other properties of fluids which include density meter, viscometer, gasometer, etc.
