The Company:
Our client is an independent oil and gas operator.

The Role:
Seven Main Categories:
1.Production Measurement, Allocations, Reporting
2.Data Management
3.Pattern Surveillance
4.Optimization – Production and Injection
6.Daily Operations
7.Reservoir Engineering Support

1.Production Measurement, Allocations, Reporting

This includes the measurement and tracking of fluids coming from each production well, and going into each injection well. Necessary to understand source of produced fluids relative to lease boundaries, pattern boundaries, and reservoir compartments, and to make sure injection tactics result maximum benefit. Reporting includes State reporting for royalty payments, as well as internal reporting for revenue accounting and co-owner accounting. Main tasks include:
•Operate the production and injection measurement systems, including well test methods, frequency, duration, and test conditions. Includes reconciliation of various measuring devices.
•Allocation of produced fluids and injected fluids by well and by pattern while reconciling individual periodic well tests, continuous ESP data, and continuous total fluid measurement at OTP.
•Satisfy all minimum State reporting needs as defined in the regulations applicable to Production Reporting to DNR, DOR. Provide and QC data for Company accounting needs.
•Review and QC KRU production and back-out volumes, as well as back out models provided by KRU to ensure that all allocations are fair and appropriate.

Frequency: Daily with specific monthly QC and reporting requirements.

2.Data Management

Work with all disciplines (facility engineers, instrument and control techs, software suppliers, Company IT personnel, PNR accounting personnel, etc.) to understand and manage the source, flow, and use of data.
•Help flow chart myriad of digital data sources, data manipulators, and data users including:
oAvocet Volumes Manager (AVM)
oMulitphase Vx Meters
oWonderware Historian Client Trend and Query tools
oInstrument Diagrams
oIndustrial SQL

Frequency: Daily

3.Pattern Surveillance

This includes the surveying and monitoring of pattern performance to ensure the patterns are performing at their highest efficiency in terms of daily production and WAG flood performance. Main tasks include:
•Work with reservoir engineer to understand what is expected (predicted) of each pattern in terms of rate, pressure, WOR performance, GOT behavior, and long term trends. Develop an understanding of horizontal well Darcy-flow drivers and Line-drive waterflood/WAG behavior drivers. Services of plots for each pattern and well.
•Use allocated data to create plots and graphs for ease of surveillance and analysis.
•Monitor production rates, production ratios (WOR, GOR), pattern pressures, injection rates, injection pressures, breakthrough response (Water and Gas), and all trends of same data.
•Monitor injection rate vs. pressure (Hall Plots) top catch earliest signs of barriers and/or plugging.

Frequency: Periodic

4.Optimization – Production and Injection

This includes the analysis of production and injection data, as well as implementation of adjustments necessary to optimize the long term value of each pattern and long term value of the reservoir as a whole.
•Artificial Lift methods: electric submersible pump (ESP) and lift gas
•Work with reservoir engineer and compare actual performance to predicted performance. Strive to improve our internal understanding of water and gas placement and subsurface flow relative to well bores, faults, and stratigraphy.
•Work with the reservoir engineer to understand WAG scheduling logic and drivers that can affect value. Look for evidence of better or worse performing patterns in terms of WAG schedules, swap-over frequency, slug volumes, etc.
•Help design, implement, and adjust the WAG schedule and swap-over plans
•Manage the production rate (ESP and Gas Lift methods) and injection rate to optimize total value of each pattern. Attention paid to the perils of overproducing a pattern, outrunning injection support, poor injections conformance, etc.

Frequency: Daily diligence and enforcement of prudent production and injection practices. An at least weekly discussion of observations and learning’s with reservoir engineer. Review of WAG schedules and adjustments as necessary.

5.Well Work

This includes helping with the proposal and justification for routine well work including through-tubing intervention, scale squeezes, and workovers.
•Monitoring well performance for signs of poor performance that can be remedied with well intervention work. Includes sanding of wells, scale deposition, poor injection or production profile conformance, etc.
•If production well or injection well performance is suffering, and well intervention can improve the point-forward value of the pattern, summarize the economic justification in terms of increased rate and incremental well work costs and submit for approval.
•As ESP’s go down, work on justification and procedures to perform ESP workover.
•Provide input for well work prioritization
•Provide input on completion design

Frequency: As needed, depending on well performance and required intervention.

6.Daily Operations

Work with on-site personnel to ensure wells and field are operated in a safe, low cost, and long term way. Work through trade-offs of short term needs and long term value. Examples may include:
•Work with on-site personnel and Centrilift to optimize ESP performance as well as Gas Lift
•Monitor fluid characteristics to understand chemical composition and its effects on metering and production handling.

Frequency: Daily

7.Reservoir Engineering Support

Work with the Reservoir Engineer to help predict rates and costs, gather data, and optimize the long term value of the subsurface asset. Tasks may include:
•Help the Reservoir Engineer gather, QC, and analyze data for estimating reservoir properties and presence/extent of discontinuities in the reservoir.
•Work with the Reservoir Engineer for opportunities to increase the value of the reservoir through additional wells, better designed wells, more optimal production or injection pressures, or other similar adjustments to the base plan. Potential use of Multi-lateral wells may be one example.
•Recommend and obtain injection well profiles (spinner, temperature) to evaluate injection conformance.

Frequency: As needed, in support of Company Reservoir Engineer
