In the upstream petroleum industry, managers are faced with an extremely complex process in forming a strategy to guide business and operations decisions. Even experienced managers often need outside opinions on their strategies, tactics and business processes. In response to a growing demand for consulting services to bridge the gap, Ryder Scott is actively involved in internal reserves audits, exploration portfolio analyses, privatization consulting and other related services.
Ryder Scott provides managerial guidance to integrated supermajors, state-owned companies and large and small independent oil and gas companies. The firm performs about a thousand consulting studies a year. By virtue of its broad experience, Ryder Scott is in a unique position to share its knowledge base through management advisory services.

Ryder Scott provides objectivity in technical matters of concern to boards of directors of E&P companies.
Decades of experience in the consulting and auditing business enable Ryder Scott senior management to
evaluate the merits of high-level internal presentations generally made to boards.
The firm evaluates the strengths and weaknesses of the proposed company strategies and then advises the board. Ryder Scott also provides advice based on its identification of technical and business risks.
Ryder Scott recommends contract modifications, where needed, to establish mutually beneficial terms in
operating and joint-venture agreements and production-sharing contracts (PSCs). Clients include both
government agencies and E&P companies.
Ryder Scott tests and incorporates optional scenarios into economic models to evaluate their relative effects. The firm recommends ways for government agencies to be systematic in monitoring field-development compliance. Ryder Scott also represents government agencies and producers in matters involving PSC revisions, pipeline allowables, well-spacing exceptions, proposed maximum efficient rates of production, etc.
Ryder Scott applies risk-assessment expertise to evaluate exploration programs in established producing areas.
Technical work varies-from defining structural traps to designing appraisal drilling programs to performing
basin-modeling work. All studies are designed to maximize income from a basin. In some cases, Ryder Scott
identifies field-development life cycles and recommends operational strategies to maximize rates of return
and minimize overdevelopment.
Ryder Scott provides the technical outsourcing services necessary to conduct risk
and option-profile evaluations and prioritization of strategic asset sales
and purchases.
Activities include the following:
Ryder Scott has extensive experience in gas-storage projects, providing services from general
consulting to prospect screening to detailed geological and engineering modeling. Services include
inventory verification and feasibility and facility-expansion studies.
Clients use simulation models as a reservoir management tool to forecast expected gas-delivery and -injection rates during cycling and to ensure that gas withdrawals are consistent with reservoir capacity, production declines and future contractual obligations.
Increasingly, state-owned companies are finding it necessary to implement international standards
in reserves reporting and overall countrywide petroleum development strategies. Ryder Scott assists
in those areas and in reserves management system design and deployment, development of stranded gas
discoveries, international financing, U.S. stock offerings and U.S. SEC reporting issues.
Under this arrangement, a Ryder Scott senior practitioner becomes an integral part of a company's
internal reserves audit management team. This team typically is composed of the client's reserves manager,
chief reservoir engineer, chief geologist and chief geophysicist. The team meets with various operating
units and examines reserves assets and "threats" to the reserves base, which, if not dealt with, might
necessitate de-booking.
The team analyzes company resources and makes recommendations, such as allocating manpower and financial commitments to mitigate reserves threats. Activities of the team may involve devising a plan to accelerate the addition of reserves or finding ways to prove up overlooked reserves.
Ryder Scott consultants typically work as members of the "company" internal multidisciplinary team while furnishing expert outside perspectives on how other oil companies handle difficult reserves issues and how regulatory compliance issues have a bearing.
Ryder Scott provides expert-witness testimony and technical research and analysis to assist in the
preparation of cases in court proceedings, arbitration hearings and meetings with state and federal regulatory
agencies. This includes technical and strategic support to management and legal teams in disputes involving
redeterminations and unitizations. Ryder Scott coordinates and supervises integrated technical teams involved
in major international arbitration. The firm works closely with attorneys to review relative merits and
weaknesses of technical arguments and to condense technical information into clear, cohesive legal submissions.
Ryder Scott audits the process by which a company manages reserves estimates, analyzing staff functions
and manpower resources required to optimize processes.
Ryder Scott provides macroeconomic analysis for the development and monetization of hydrocarbon resources.
Services may include hydrocarbon resource market analysis, country or basin entry and/or exiting evaluations,
early exploration strategies and risk assessment, asset development strategies and cost-of-service modeling. Ryder
Scott is also in an excellent position to recommend strategies for acquisitions and divestitures.
Ryder Scott provides support to state-owned, public and private oil companies during contract negotiations.
The strong technical backgrounds of Ryder Scott personnel better position them to identify negotiating currencies.
Those personnel actively participate during negotiations, evaluating proposals and counterproposals and identifying opportunities and pitfalls.
By commissioning a reliable, independent consultant, investment banks reduce the risks associated with financing
multimillion-dollar acquisitions. Ryder Scott provides expert advice on oil and gas property transactions involving
major, independent and national oil companies. Services range from advising top-level management to conducting
valuations of each field within a property package. Ryder Scott also provides complete data-room management with a
focus on understanding the needs of potential buyers. This greatly streamlines the proved, probable and possible
reserves determination process, which allows buyers to focus on upside potential outside of traditional
considerations. This ensures that both buyers and sellers mutually benefit from property transactions.
Ryder Scott has conducted countrywide reserves and economic studies to establish an economic basis for
privatization of state-owned companies. Ryder Scott assists companies issuing equities by making presentations to
regulatory agencies, potential investors, brokers, analysts, portfolio managers and institutional traders.
The firm conducts reserves certifications to ensure that the company reports reserves in accordance with internationally accepted standards.
Ryder Scott reviews, compares and standardizes corporate procedures among different affiliates to ensure
consistency. These services provide clients with the ability to better compare and contrast results from various
affiliates through the use of consistent yardsticks. Third-party involvement facilitates implementation and acceptance
of new standards by affiliates, because they perceive that those policies are based on recommendations from an
independent advisor and not from a "competing" affiliate.

Ryder Scott designs reserves management systems that combine and integrate processes, software and personnel to enable a company to efficiently track changes in reserves quantification and classification. The systems enable management to make decisions on property portfolios, including acquisitions and divestitures, exploration and development, reservoir and field management and other upstream activities.
The design of the reserves management process includes charting workflow, timing events and integrating the process with proper software and databases. Ryder Scott collaborates with software vendors to enhance commercial applications to more efficiently manage clients' reserves databases.
Solutions vary from custom to commercial to integrated, hybrid systems that help eliminate redundancy and inefficiency. Ryder Scott develops custom software applications for reserves evaluations and other technical tasks if commercial programs cannot meet client needs.
The firm offers low-cost proprietary programs to clients as a courtesy. Ryder Scott's primary business is not software development or vending.
Furthermore, the firm has no ownership interests in any hardware or software developers. This ensures that Ryder Scott recommendations are unbiased.
Ryder Scott examines major field assets for proper deployment of numerical simulation techniques. Through scoping studies,
the firm reviews portfolios to determine where simulation is essential for future development or divestiture. Ryder Scott
also recommends and uses other evaluation techniques in cases where simulation may not be a logical, cost-efficient tool
of choice. For existing or proposed projects, the firm conducts reviews to prioritize technical expenditures to ensure
maximum benefit and return on assets.
Ryder Scott presents a variety of custom-designed reserves seminars to fulfill a wide range of needs. This includes
schools, workshops and training sessions in reserves estimation methods, reserves definitions, reserves reporting for public
stock offerings, probabilistic assessment of reserves and reservoir simulation. The firm also produces custom manuals on
reserves-estimation procedures and computer program documentation.
