Production
|
The RBDMS program includes basic components for
tracking, storing, and evaluating oil & gas production data.
The system was built to accommodate production accounting on a lease/unit
basis and/or by well and distinct producing formation. Lease
and/or unit information can be tracked, including the wells assigned
to a particular lease or unit. Production inventory disposition
is tracked by production reporting unit. Production by well
can be tracked in a manner to account for production by distinct
producing formation if production is not commingled downhole.
Historical and cumulative production from multiple producing formations
is also addressed by the system.

Subsurface Geology
"Montana Mud Mound"
|
RBDMS comprehensively addresses subsurface
geologic issues. The system allows for storage of subsurface
geologic formations, including standard and non-standard identifier
codes as well as corresponding image maps for use GIS applications
or in other third party programs. RBDMS is also used to store
identified formation tops for individual wellbores, including information
on oil and/or gas shows, and the source of the pick. Other
related functional areas that are addressed in the RBDMS program
include well cards (or scout tickets), core cards, stimulations,
completion details (e.g., perforations), production tests, geophysical
logs, well histories, and more...

Underground
Injection Control
Discussion of Functional
Capabilities Available in RBDMS
RBDMS
includes the basic components of a Management Information System (MIS)
that can be used by a state or federal regulatory agency to aid in the
implementation of an Underground Injection Control (UIC) Program. To
compliment these basic components, ALL staff have worked with the Ground
Water Protection Council (GWPC) and several states developing custom
solutions that expand the capabilities of these basic functions to fully
meet the needs of a state-specific UIC program.
Some of the components that
are included in either the basic version of RBDMS or that have been developed
as part of custom implementation efforts are listed in Exhibit 1 (below):

UIC Permits
|
The UIC Permits module provides users with the ability
to track permits initially issued for an injection well and recurring
modifications. The module also allows users to track both single well
and area permits, wells on a permit, and includes several standard
reports. Multiple customized data entry interfaces have been developed.
|
|
Well/Well Activity and Location Tracking
|
Both the basic and expanded versions of RBDMS include
comprehensive well, well activity, and location tracking systems.
Included in these are tracking of UIC components, such as compliance/file
reviews, testing schedules, water analyses, and more. This component
of RBDMS also addresses functional requirements pertaining to well
completions, confidential record status, and submittals from permittees
(e.g., logs, cores, pressure tests, etc.).
|
|
Area of Reviews
|
RBDMS has multiple components to address this important
aspect of any UIC program. Tools and components include an AOR tracking
module, a utility to find wells within an AOR study area, an AOR Variance
Questionnaire, Zone of Endangering Influence (ZOEI) determinations,
and associated reports.
|
|
Mechanical Integrity Tests
|
Both internal (part 1) and external (part 2) mechanical
integrity testing information is provided for in RBDMS. These components
also give users the ability to manipulate the database for planning
fieldwork, addressing delinquencies, and data analysis.
|
|
Compliance and Enforcement
|
The compliance and enforcement module within RBDMS
was designed to meet minimum EPA requirements for state or federal
agencies implementing a UIC program. The tool contains information
on SNC determinations, violation tracking, compliance schedules, and
corrective actions. This module is currently being expanded for the
Michigan Geological Survey.
|
|
Complaints and Incidents
|
RBDMS allows users to track complaints and incidents
by well or location. Incident reports can initiate field investigations
and/or enforcement actions.
|
|
Well Inspections
|
Field activities, such as well inspections, are a key
component to RBDMS as relates to all well types. The well inspection
component can be used to track inspections for EPA reporting as well
as other purposes.
|
|
Injection Monitoring and Analysis
|
Multiple interfaces exist for data entry of injection
well monitoring data, including situations where data is reported
monthly or annually, by well or project, or in specified groups or
orders. A graphical analysis package has also been developed and is
being used by a select group of state agencies.
|
|
Environmental Risk Analysis
|
RBDMS includes multiple components that can be used
to analyze environmental risks posed by injection well activities.
These include probability analyses performed using multiple filtering
criteria, barriers of protection analysis, and innumerable system
queries and reports. In Kansas, a reference database of sensitive
groundwater areas has also been integrated into RBDMS. These analyses
can be used to prioritize environmental protection resources, address
complaints, support plugging-enforcement-testing priorities, as well
as provide support for other program areas.
|
|
EPA 7520 Reports
|
EPA 7520 reports have been developed in RBDMS. The
basic version provides the ability to automatically generate these
reports for Class II injection wells. Reports for other well classes
have also been developed as part of custom efforts.
|
Although
all UIC programs (state, federal, Indian Lands, or other) are generally
driven by the requirements of the Safe Drinking Water Act and its amendments,
each program tends to be somewhat different. These differences may be
attributable to local geological conditions, historical practices, environmental
sensitivities peculiar to a specific area, or other considerations. Implementing
RBDMS may require that basic components of the system be customized to
meet the specific needs of a regulatory or natural resources conservation
agency.
ALL-LLC staff have not only
assisted states with customized implementations of RBDMS, but has also
served in regulatory leadership roles at both the state and federal level.
ALL-LLCs RBDMS project team includes professionals with backgrounds
in state and federal UIC programs, upstream petroleum practices, state
and federal regulatory history, groundwater hydrogeology, workflow analysis,
geo-spatial analysis, information system design, and environmental sciences.
These skills, combined with broad experience implementing large-scale,
mission-critical information systems, is unmatched.

Well
Locations and Identifiers
RBDMS provides for the storage of well location and identifier information
in a very detailed manner. Standard land grid systems such
as section, township, range are addressed as well as latitude/longitude,
X/Y coordinates, USGS Quadrangles, Counties, and more. In
early American history, Ohio was a testing ground for land grid
systems. Because of this, Ohio has served as a testing ground
for expansion of the RBDMS location system. Ohio has 12 separate
land grid systems.
The
primary well identifier used in RBDMS is the API Well Number (14-digit).
The API well number is used throughout the system to track well
information and histories. However, the system provides for
several alternate identifiers to allow for later analysis and well
identity confirmation by system users.

Well
Components
Well components are a critical aspect of tracking oil & gas and
related injection wells. RBDMS provides several fully-relational
database tables to store and track well construction and completion
information. The system stores information on boreholes, tubulars,
and equipment (e.g., DV-tools, packers, etc.). For tubulars,
the system also provides for the ability to specify details of individual
well tubulars such as weight and grade.
RBDMS also facilitates
capturing of well cementing and plug information, including the
makeup of individual cemented intervals or plugs, gel plugs, gravel,
etc.
Completion information
is also stored in the system, including information on applicable
perforations, screened intervals, or open hole intervals that may
be present in the well. For each interval, details of the
interval can also be stored (e.g., shots per foot).

Handling
Wells, Wellbores, and Well Details in RBDMS
Well information can be quite
complicated when data must be maintained on wells having multi-lateral
completions, directional drain-holes, sidetracks, recompletions, re-drills,
workovers, and more. These complexities, combined with state-specific
regulations that may be both technically or legislatively based, has resulted
in continuous improvements to logic used in custom implementations of
RBDMS.
The fully relational nature
of RBDMS, combined with expanded features that have been built or are
under construction in custom implementations of RBDMS, provides the tools
necessary to track and maintain detailed information for wells by API
Well Number, Well Permit Number, UIC Permit Number, or an unlimited number
of other tracking numbers. New developments have been designed to allow
users to track well data by surface location or by individual borehole.
Part of this new development
effort includes tools and utilities that allow users to filter and review
data for each record associated with a particular surface location. Utilities
have also been developed to facilitate maintenance of data on multiple
wellbores that may exist in the database for status changes and other
activities. These utilities have also been tied to production tracking,
proration, and disposition. New utilities for automatically creating well
permits and unique well identifiers have also been prepared.
This approach enables users
to more freely track not only well details, but also well activities for
a specific wellbore. This tracking can be carried from the application
stage, into production or injection, and through plugging and abandonment.
