Comprendre le concept de "Travail" dans l'industrie pétrolière et gazière : au-delà de la définition de base

Le mot "travail" possède une signification simple et universelle - l'exécution de tout service utile pour lequel un paiement doit être effectué. Cependant, dans le paysage complexe de l'industrie pétrolière et gazière, le "travail" prend un rôle plus nuancé, englobant un large éventail d'activités et de responsabilités.

Voici une ventilation de la façon dont le "travail" est utilisé dans le pétrole et le gaz, avec des exemples spécifiques pour illustrer ses différentes applications :

1. Étendue des travaux :

Définition : Cela fait référence aux tâches et responsabilités spécifiques définies dans un contrat pour un projet particulier. Il définit les limites de ce qui est inclus dans l'accord et ce qui constitue le "travail" à effectuer.
Exemple : Une étendue de travaux pour un projet de forage de puits pourrait inclure des activités telles que la préparation du site, les opérations de forage, l'achèvement du puits et les essais.

2. Ordre de travail :

Définition : Un document officiel qui autorise l'exécution de tâches spécifiques dans le cadre d'un projet. Il décrit les travaux requis, les délais, les ressources et les responsabilités.
Exemple : Un ordre de travail pour un projet de réparation de pipeline pourrait spécifier l'emplacement des dommages, les matériaux nécessaires, l'entrepreneur responsable et la date de fin prévue.

3. Intervention sur puits :

Définition : Cela fait référence aux opérations effectuées sur un puits existant pour améliorer sa production ou résoudre des problèmes. Il implique la manipulation de composants de puits tels que le tubage, le tubage et l'équipement de fond de puits.
Exemple : Une intervention sur puits pourrait être nécessaire pour éliminer l'accumulation de paraffine dans un puits, stimuler la production en injectant des produits chimiques ou remplacer du matériel usé.

4. Travaux en cours (WIP) :

Définition : Cela fait référence aux tâches ou projets qui sont actuellement en cours d'exécution mais qui ne sont pas encore terminés. Le WIP est souvent suivi pour surveiller l'avancement du projet et identifier les goulets d'étranglement potentiels.
Exemple : Une plate-forme de forage en activité dans un champ spécifique est considérée comme un travail en cours, car elle effectue actuellement des tâches liées à l'extraction de pétrole ou de gaz.

5. Permis de travail :

Définition : Un document qui autorise l'exécution d'activités de travail spécifiques dans une zone désignée, en particulier dans des environnements comportant des risques de sécurité. Il décrit les précautions et les procédures nécessaires à suivre.
Exemple : Un permis de travail pourrait être requis pour les travaux à chaud tels que le soudage ou la coupe sur une plate-forme pétrolière, garantissant la mise en place de mesures de sécurité appropriées.

6. Plate-forme d'intervention sur puits :

Définition : Il s'agit d'une plate-forme spécialisée utilisée pour effectuer des opérations d'intervention sur puits sur des puits existants. Il est équipé d'outils et d'équipements conçus pour les interventions de fond de puits et l'entretien des puits.
Exemple : Une plate-forme d'intervention sur puits peut être déployée pour effectuer un travail de fracturation, qui consiste à injecter des fluides dans un puits pour fracturer la formation rocheuse environnante, augmentant ainsi la production de pétrole ou de gaz.

Conclusion :

"Travail" dans l'industrie pétrolière et gazière signifie bien plus que la simple exécution de services. Il englobe les processus complexes, les opérations spécifiques et les équipements spécialisés qui conduisent à l'exploration, l'extraction et la production d'hydrocarbures. Comprendre les différentes nuances du "travail" est essentiel pour des opérations réussies, une communication efficace et une bonne gestion de projet au sein de cette industrie complexe et exigeante.

Exercise:

Scenario:

You are a junior engineer working on a project to upgrade an existing oil well. The project involves installing new downhole equipment, replacing the existing tubing, and conducting a frac job. You need to create a "Work Scope" for this project.

Instructions:

Identify the main tasks and responsibilities for the project.
Organize them into logical categories.
Describe the key deliverables for each category.

Example:

Category: Well Preparation

Tasks:

Shutting in the well.
Removing existing downhole equipment.
Installing new downhole equipment.

Deliverables:

Well safely shut in.
Existing downhole equipment removed and stored.
New downhole equipment installed and operational.

You can use the example above as a starting point to create a complete "Work Scope" for the oil well upgrade project.

Exercice Correction

A possible Work Scope for this project could look like this:
