Oil & Gas Laboratory Testing & Analysis

Oil & Gas Laboratory Testing & Analysis

OBJECTIVES

• Grasp the physical and chemical concepts involved in various analyzes,
• Comprehend issues requiring special attention in various analyzes,
• Assess the results of an analysis and decide whether to carry out the analysis over again,
• Review main occupational health and safety rules within the framework of laboratory activities.

WHO SHOULD ATTEND?

Laboratory personnel, operational staff and other professionals interested in laboratory analyzes dedicated to Oil & Gas operations.

COURSE OUTLINE

Role & responsibilities of laboratory staff

• Member of production staff. Equipment yields controls/monitoring.
• Final product quality controls/monitoring. Recommendations to improve treatments

Analyzes specific to crude oil

• Specific gravity or density.
• Vapor pressure (reid vp).
• Water content: basic sediment & water (bsw), dean stark distillation.
• Salt content: chlorides content, conductimetry.
• Acid components content:
• H₂s content (methylene blue).
• H₂s and mercaptans by potentiometry.
• Total acid number (tan) of liquid hydrocarbons.
• Fluid rheology: pour point, kinematic viscosity, wax content.

Analyzes specific to gas

• Gas characterization analyzes:
• Dew point (hc and water).
• Gas composition by gas phase chromatography (gpc).
• Gas specific gravity estimate from composition.
• Acid components content:
• H₂s content (dräger), h₂s and mercaptans content (potentiometry, iodometry).
• Co₂content (dräger and acidimetry).

Analyzes for the follow-up of effluent treatment operations

• Demulsifiers evaluation and selection (bottle tests, field tests).
• Quality controls/monitoring of poor and rich triethyleneglycol (teg):
• Water content, ph.
• Hydrocarbon content.
• Follow-up of equipment performances: water content, residual emulsion.

 Analyzes done to optimize anticorrosion treatments

• Deposits and scale analyzes.
• Chemical corrosion and bacterial corrosion appraisal.
• Recommendations for chemical additives and treatments.

Hse in laboratory activities

• Laboratory facilities design and implementation.
• Chemicals management (storage, use…).
• Occupational health and safety behavior.
