Procurement is conducted to provide existing and potential suppliers the same opportunity to compete openly and fully through Sourcing events.

Awarded suppliers are notified of a request for delivery of products or services via a Purchase Order (PO). The Purchase Order is the primary purchasing methods employed by Schlumberger. No goods or services shall be supplied without a valid and pre-approved Schlumberger Purchase Order, indicating types, quantities, and agreed prices for the products or services.

Suppliers should request a valid PO prior to delivering goods or services or submitting an invoice. Schlumberger reserves the right to reject an invoice without a valid PO.

Advantages of adopting the Purchase Order Process are:

The approval process tied to our Purchase Order process gives Suppliers an assurance that the order has been approved by Schlumberger.
An approved document minimizes the likelihood of queries, disputes and possible legal consequences.
It also ensures that Suppliers receive all the necessary information which shall be included in the invoice to minimize the risk of extra administration and payment delays.
Reception and processing of invoices are made easier when a Purchase Order number is provided, enabling the original order to be found quickly, and the receipt compared (3-way match).

Throughout the Source-to-Pay process, we utilize digital capabilities to exchange documents and information with suppliers as well as to monitor compliance. Suppliers are expected to fully adopt the digital solutions as indicated by Schlumberger.

How to participate in new sourcing opportunities

Schlumberger's official tool for receiving supplier offers is Ariba Sourcing. This is a web-based application which allows suppliers to respond to their request for information and participate in the sourcing opportunities. It enables online collaboration and exchange of information. To enable the use of Ariba Sourcing you require an Ariba Standard account (no cost to set up). All proposals and quotations received are evaluated based on quality, service, compliance to specifications and price. All awards are made in the best interest of the company.

How to transact via Purchase Order

Once you are an awarded vendor, you will be fully onboarded to receive Purchase Orders.

Schlumberger is in the process of implementing a single SAP solution across the entire organization. Ariba Network will become the primary channel for the interactions throughout the Procure to Pay process. Exceptions and deployment information will be communicated by your Supply Chain point of contact.

Once your account is set up, you will be able to receive Purchase Orders from the Ariba Network.

When a PO is issued, you will receive an email with a link to the system. For non-SAP deployed regions, other purchasing systems are used in a similar manner.

It is very important to acknowledge the Purchase Order in the system to confirm that the services and/or goods can be provided as per required dates, quantities and description. Incoterms and Point of Delivery shall also be very clear to determine buyer and seller responsibilities.

Legacy systems:

You will receive an email from SWPS (Schlumberger Web Procurement System) or Oracle. Once clicking in the link your browser will open a window for acknowledgement of the order.

Logistics carriers

You will receive an email from the OTM (Oracle Transportation Management) system and similarly will be able to review the orders and acknowledge.

What is changing for SAP deployed regions?

Ariba Network account is required to receive Purchase Orders, Submit Invoices, Credit Memos, track payment status. Make sure this is communicated to you organization to ensure all parties are aligned with the changes

Tip 1: Create a shared mailbox for PO emails and add qualified users to manage your interactive emails from Ariba Schlumberger   

Tip 2: Do not delete your interactive emails, especially if using a standard free account.   

Tip 3: As an Ariba Network supplier, you have two choices for Ariba Network accounts. The Ariba Network Standard version is free and sufficient to transact with Schlumberger. The Enterprise account offers advanced capabilities, but additional fees apply, and these are not covered by Schlumberger.

How to deliver your goods and services

If the Purchase Order Incoterms indicate that it is Schlumberger’s responsibility to arrange for delivery, once the order is ready the supplier can send the Advance Shipping Notice to Schlumberger. For SAP-deployed regions, Advanced Shipping Notices can be shared via Ariba Network. Multiple ship notices per purchase order might be sent. NOTE: An actual or estimated shipping date is required on all ship notices.

Delivery terms and other transportation details can be included on all advance ship notices to support a broader range of shipping information.

All suppliers are expected to adhere to international or regional agreements as appropriate. All vendors are responsible for providing appropriate documentation such as manufacturing origin certifications for duty relief.
