Who are we? (Hint: we are not a vendor…)

• Energistics is a global, non-profit, membership consortium focused

on developing open data exchange standards in the upstream oil and

gas industry. We have served the industry for more than 25 years.

• Our membership consists of E&P companies, oilfield service

companies, software vendors, system integrators, regulatory

agencies and the global standards community

• Our standards are developed by workgroups (known as Special

Interest Groups, or SIGs) made up of industry experts from our

member companies

• In short, the standards are created by the industry for the industry

Original WITSML Business Challenge

• Operator challenge:

– Consistent view of

services

– Conform to corporate

standards (Security,

audits, reporting, etc.)

– Allow:

• Sharing with partners

• Data management

• Integration

Operators:

Version 1.X Use Cases

• Consistent high-quality transfer of

wellbore and drilling-related data

– Data transfer to real-time operations

centers

• Reference objects – Well and Wellbore

• Growing objects – Log (time, depth),

Trajectory, Mudlog

• Snapshots in time – with “report” information

– Move well-related data between

applications

– Real-time availability of drilling operations

WITSML Scope

• Distinct classes of objects

– Reference objects – Well and Wellbore

– Growing objects – Log (time,depth), Trajectory,

Mudlog

– Snapshots in time – with “report” information

• Communications process

– Simplify problem: point to point

– Any number of point to point steps in a larger

communications chain of events

• Solution requires

– Mechanism for communicating between 2 end

points

– Object definitions for the transfer of data

WITSML Misunderstandings

• Rig to Office transfer

– Most WITSML transfers are not from the rig

• Real time only

– Transfer of data collected in real time.

– Near-real time & historic transfer

• Producer / Consumer only

– A consumer may also be a producer, allowing for more complex

implementation including data collection, assimilation and aggregation

services

• Intended to replace WITS

– Extended WITS capabilities to allow cross-firewall data transfer

– Market drivers select data standards

New Requirements on Transfer Standards

• Big data/analytics

– Analytics on data in motion

• High-performance transfer standards

• Broader workflows – not just well site to

office

– Application to application

– File-based transfers

– Archival workflows

– Expanded metadata

Integrated

• Among the MLs

• Between the standards bodies

– SEGY/SEGD in epc

– HDF use

– OGC in MLs

– IEP/ISO 19115

– MathML coming

ETP: Protocols

» ETP is a new data exchange specification

» Enables real-time data transfer between applications

» Is delivered as a specification and as sample code

» Works by sending pre-defined messages

• The messages are grouped together into “protocols”

• The description of these protocols make up the standard

» No server required, just sender and receiver

WITSML to RESQML How do we construct the connection?

Slide 18

OGC ®

MD

Make sure the MD definition of the trajectory is specified

Convert to Local CRS for RESQML

1. Create a permanent reference geometry:

the Wellbore trajectory

3. Attach Properties / Markers to the

Wellbore Frame:

Properties may be on the ticks (nodes), or

between ticks (intervals)

From the Driller to the Reservoir Engineer

Slide 19

2. Create a reference WelboreFrame along the

trajectory

Choose an MD sampling interval for each log type
