Deliverable 2 and 3: Documentation of 2008 SPE Digital Energy Conference Workshop Content on JVR

Up one level to Standard Use Case Format

Up two levels to the Project Process

Summary of workshop experience: During the workshop, only two groups concentrated their discussion on the subject of JVR. Their efforts have been compiled as shown in the following sections. The groups were given an example of use case documentation by Merrick Systems (Appendix D). In order to better document the workshop content, the COT team has placed them into the format outlined in Appendix D on use case documentation.

The workshop experience showed many instances where the JVR content could be expanded and carried towards processes with no direct involvement in the end results. For example, each group’s approach has been observed to cover processes at the pumps, well tests, and even reservoir simulation data processing. Most of the members of the audience may have been exposed to forming a use case scenario for the first time. Learning use cases and their purpose may have added to the uncertainty and chaos of the thought process during the workshop. More importantly, each company/person has a different experience within the JVR process; hence, no two workflows developed in the workshop were identical. In a sense, no workflow exists in isolation from all other processes in the Operator-Partner relationship. Therefore, the workshop attendants needed to go back to the basic upstream processes before they could effectively discuss specific issues in JVR.

Lessons learned as a suggestion for future workshops of a similar nature:

  1. The tool utilized in the workshop should be very simple and straightforward for participants of the workshop to follow. Pre-screening can be performed if the use of a complex tool is absolutely necessary. Otherwise, a basic questionnaire might be sufficient to gather input from the community.
  2. Pre-screening is also suggested so that workshop participants can be ranked according to their level of expertise. This way, workshop teams can be formed around encompassing a broad range of expertise (i.e. match less experienced participants with more experienced participants) on a particular subject. This framework would create a better balance of knowledge within workshop teams.
  3. Each workshop team should be provided with specific focus points. The topic should be divided into basic concepts to guide discussions. A questionnaire can be administered to participants at the beginning of the workshop to collect specific information regarding the main theme of the workshop.
  4. Previously identified opposing viewpoints within the themes/discussion topics should be emphasized in workshop materials to guide discussions. These viewpoints could be included in the tool of choice or in the discussion points provided for each workshop team. If teams are aware of universal problems or disagreements on a subject, participants may be more interested in staying on task within their discussions.
  5. Consideration should be given to providing a knowledgeable facilitator for each team.

2. Maintenance/Mechanics
3. Optimization Technician
4. Production Engineer
5. POC
6. RTU
7. Automation System

Methods to Make RTO Data Available

1. EDI, XML (PRODML, WITSML), CSV, proprietary formats
2. Web services or other APIs pull data from SCADA/DCS systems or data librarians
3. Portal for online access, data loading, alarms, notifications, dashboards

Source Data for RTO Workflows

1. Monthly oil, gas, water rates
2. Revenue by well, lease, field
3. Costs by well, lease, field
4. Lease operating statements
5. Field tickets
6. Well tests – oil, gas, water rates, psi, pressure transient analysis
7. Fluid composition – PVT data
8. Reservoir simulation data
9. Petrophysical data
10. Production log data
11. MWD/LWD
12. Forecasted and actual targets

PURPOSE: Optimize production and reduce costs of many low volume wells.

BRIEF DESCRIPTION: Optimization should concentrate on instrumentation for the most impact. Shell uses low cost pressure meters to capture information in order to high grade a well model. Shell has successfully reduced costs and number of workovers.

PRE-CONDITIONS

FLOW:
• Pumper: Data collection, well status evaluation (currently, pumpers drive routes).
• Maintenance: Fix well.
• Optimization Engineer: Take results and make recommendations to optimize.
• Production Engineers: Decline analysis and data analysis.

Second Flow:
• Instrumentation: POC RTU, PLC - gather data.
• Pumper: Inspection of the Well 0 Dynographs
• Maintenance, etc. the same.

SPECIAL REQUIREMENTS

POST-CONDITIONS

USER INTERFACE

ISSUES: Security, tracking delivery, service level agreements, and contractual commitments

BRIEF DESCRIPTION

PRE-CONDITIONS

FLOW: See photos of work on flipcharts in Appendix E. A description of flipcharts (with the help of SME meeting Appendix B #28) is included here.

SPECIAL REQUIREMENTS

POST-CONDITIONS

USER INTERFACE

ISSUES: Data quality and availability are the major underlying causes for trouble in Partner reporting.

COMMENTS: Trust both internally and externally is a key factor to address.

The diagrams depicted in the photos (see Appendix E) were drawn by James Crompton. Some explanation of this group’s work has been clarified by Cheryl Dugger during the SME meetings (Appendix B-#9) and James Crompton (Appendix B-#28).

Raw measurements come from SCADA systems or some other FDC system. Engineers and accountants receive this data and perform some statistical analysis. The accounting department receives this raw data for cost allocation. Back allocation of data is where there is a need for a better work process. If there is a problem with the numbers, it should be addressed before/during the time they are sent to the finance department since they “cleanse” the numbers to suit the production requirements.

There was also discussion on data quality. It is very seldom that joint Partners receive the same data as the financial departments. The Partners would prefer to see the numbers coming straight from the SCADA systems to prevent their manipulation by the accounting department. The SCADA system captures data from RTUs (Real Time Units) and sensors, which are then put into technical data repositories (like OSI Pi system). Earlier there were limited ways to gather data, now that there are many varied methods of data capture the JV Partners would like to see the data regularly to increase the efficiency of production.

DELIVERABLE III: DISCUSSION OF WORKSHOP RESULTS WITH SUBJECT MATTER EXPERTS

All information gathered from the workshop has been incorporated into the project in terms of providing the impetus for questions to ask in meetings with SMEs or direct incorporation with the workflow documentation as descriptors and variations of the reporting process.
