Introduction
 Management of Change (MOC) is the process to manage
significant changes associated with deviations from
contractual terms and conditions, work-scope, historical
norms, procedures and work instructions.
 Exemption is the process to obtain appropriate approval for
deviation from Schlumberger policies and standards for a
specific period of time.

Introduction
 Significant Change: Any change that introduces new
hazards, or any change that causes an increase in the level
of the risk, that has the potential to result in an HSE accident
or an SQ non-conformance. Such changes may be
incremental, but over time can be significant.
 A change is not only from procedures and work instructions
but also from historical norms in terms of work-scope,
activities and conditions, job programs, quality plans,
personnel changes, equipment changes.
 Environment, Equipment, Personnel & Process

Introduction
 Originator: The individual employee who makes the documented
‘Management of Change’ or ‘Exemption’ request. The Originator
is generally a Line Manager with responsibility for the work area
or process where the deviation has been identified.
 Approver: The individual(s) with the ultimate responsibility to
approve or reject the request for a deviation:
 For the Exemption process, generally a line manager in the
organization in which the policy or standard was published.
 For the Management of Change process, generally found in the
engineering, technical or operations management chain that
originally approved/signed off the contract, equipment, job, etc.

Objectives
 Description of what to do when significant change is
introduced following deviation from:
 Contractual terms and conditions, work-scope, historical
norms, procedures, work instructions, using the Management
of Change process; Policies and standards; using the
Exemption process.
 All significant changes to design, equipment, and operations,
as well as deviations from policies and standards, must be
justified, approved, recorded, and monitored in a controlled
and effective manner

Methodology
 The Originator identifies or acknowledges the deviation and
the nature of the significant change
 The Originator and where applicable, his/her direct line
manager set up a risk assessment team
 The risk assessment team performs a comprehensive initial
risk assessment to determine the potential risk if the
activity /process continues without any further measures
being applied to control the deviation/significant change
(Guide: SLB-QHSE-S020 & SLB-QHSE-S002)
 The risk assessment team develops a risk control plan,
including both prevention and mitigation measures

8. SchlumbergerPrivate

Methodology
 The risk assessment team completes the risk assessment by
defining the residual risk that will exist if the activity /process
continues with all planned risk control measures
implemented and followed
 The Originator requests approval from the relevant Approver
 The Approver(s) reviews all the details of the request
 Upon approval, the Originator must ensure that the
Management of Change and/or Exemption details are
thoroughly communicated to all those involved, including
third parties, and also including any newcomers that may
arrive after its initial implementation

Methodology
 The activity is performed at the defined residual risk level
with all agreed control measures in place
 Upon completion of the deviated activity or on expiry of the
request validity period, the Originator must ensure that the
Management of Change and/or the Exemption is closed out
appropriately
 If rejected then the request is closed and any subsequent
request for approval is documented on a new request
document

Compliance Monitoring
 To allow compliance monitoring, all Management of Change

 Geomarket HSE Manager for exemptions approved by
Geomarket Manager or Operations Manager;
 Area HSE Manager for exemptions approved by Area
President or Area Business Manager;
