WITSML Web Services (“API”)

• SOAP Interfaces defined in WSDL

• Store Interface– GetFromStore()– AddToStore()– UpdateInStore()– DeleteFromStore()

• Publish/Subscribe Interface– Subscribe()

• Both Interfaces– GetVersion()– GetCapability()

Introduction

• Standards for sending well site information in an XML document format between business partners.

• XML schemas define the content of an XML document.

• Two specifications: Data Schema and Web Services.• A data object schema defines a set of data that can

be transmitted within a single WITSML document and represents a cohesive subset (e.g.; well, wellbore, rig, etc.) of an overall logical schema related to a single domain (well).

• Data object schemas contain attributes, elements, and included component sub-schemas.

10

Data objects - 1

• aggregate: to transport multiple objects• attachment: a digital attachment to an object [base 64]• bhaRun: a run of the drillstring into/out-of the hole. • cementJob: a cement job.• changeLog: knowledge of object changes in a Server.• convCore: a conventional core. [geology, lithology]• coordinateReferenceSystem: defines a CRS in GML• drillReport: a daily drilling report to partners or agency• fluidsReport: an analysis of the drilling mud. • formationMarker: a geologic formation in a wellbore.

11

Data Objects - 2

• log: the curves on an LWD well log. • message: informative message about a related

object. • mudLog: the information in a mud log. • opsReport: a daily drilling report from service

company• realtime: transient data in (near) realtime mode• report: provides context to objects in an aggregate.• rig: a drilling rig.• risk: risk information about other objects.• sidewallCore: a core from the side of a borehole.• surveyProgram: description of a directional survey.

12

Data Objects - 3

• target: intended targets of a trajectory survey. • trajectory: a directional survey in a wellbore. • trajectoryStation: a single station in a trajectory

survey. • tubular: the configuration of a drill string. • wbGeometry: the configuration of the

permanently installed components in a wellbore. • well: general information about a well. • wellbore: general information about a wellbore. • wellLog: sets of logging curves within one run.

Wireline supported.

WITSML Standards: Simplicity and Integration

• A framework for– Energy companies– Field Service companies– Software providers

• To – Configure– Deploy– Operate

• Efficient means of– Collecting– Validating– Integrating– Using

• Real-time and contextual drilling data.
