We have extensive local knowledge supported by the international network of expertise and capabilities within our organisation.

RPS & UNCONVENTIONAL GAS

Our Unconventional Gas History

RPS first became involved with tight gas, Coal Bed Methane (CBM)/Coal Seam Gas (CSG), shale gas and ultra-tight gas through project work in the United States with the Gas Research Institute and the Department of Energy. RPS is actively involved in the transfer of technology and leveraging our North American experience with unconventional gas evaluation and development to the other operating regions.

We have steadily expanded our involvement in frontier hydrocarbon developments such as Underground Coal Gasification (UCG) and gas hydrates.

Our participation in research and development has extended to support pilot testing of Underground Coal Gasification (UCG) and gas hydrate coring and production tests.

Our greatest contribution to the commercialisation of new sources of energy has been through:

n Identification and evaluation of new business opportunities

n Technical support to data acquisition and interpretation

n Application and dissemination of leading edge evaluation and development technologies

n Facilitation of E&P activities through the timely management of the required approvals

n Preparation of evaluations used in raising finances.

How RPS Can Help

RPS provides strategic and commercial advice and technical support to gas exploration and development worldwide.

As with all projects, success requires a coordinated and integrated approach not only to geoscience, engineering and commercial analysis, but also to Environmental Impact Assessments (EIAs) and stakeholder and approvals management.

We have been involved with several unconventional gas projects in North America, South America, Australia, UK, Europe, Africa, China, India and Indonesia.

RPS offers support to geoscience operations in planning, permitting, positioning and quality control (QC) of seismic acquisition, as well as in processing and interpretation of data.

New plays depend heavily on the accurate description of the cap rock and potential pay zone, fit-for-purpose coring programs with proper handling of cores, complete analysis and detailed core description, as well as DST or injectivity test planning and analysis. Our well site teams offer all of these services.

Unconventional gas production poses operational challenges in the supply of water for field operations, the treatment and disposal of flow-back fluids,associated permitting and aquifer monitoring requirements.

Unconventional gas resources will play an increasingly important role in fulfilling future energy requirements as conventional sources of natural gas mature and decline or become more costly to exploit.

UNCONVENTIONAL GAS RESOURCE PLAYS

Unconventional gas is generally contained in large accumulations which challenge our common perceptions of what constitutes reservoir rock.

Non-conventional drilling, stimulation or operating procedures are usually required in order to produce at commercial rates of gas flows. The key to commercialisation is to identify enabling technologies and the most productive sweet spots.

Unconventional wells generally produce at rates that are deemed uneconomic by the conventional gas industry. In 2008, more than 65,000 unconventional wells in North America were producing on average only 0.12 MMscf/d/well.

However, the well costs are paid out under initial transient production conditions when much higher rates are achieved, especially from fractured stimulated tight sands and shale gas wells.

Operating at low average rates requires economies of scale and close attention to operating expenses and maintenance costs. Non-conventional materials are used to minimise costs and corrosion. Ongoing drilling and gas compression are significant components of the gas supply costs.

By taking advantage of well manufacturing processes over large land holdings, unconventional gas Finding and Development (F&D) costs can be kept relatively low.

RPS Energy has the resources and considerable experience to support client activities at each of these stages.

STAGE 1A Opportunity Identification

Identification of a successful resource play is based on detailed basin and geochemical studies in comparison with the major unconventional resource developments in North America.

RPS has completed scouting studies and due dilligence excercises for acreage acquisition purposes in many basins around the world.

Exploration is not the only entry option. RPS has the ability to evaluate and quickly characterise large data-sets in a way that facilitates forecasting the likely range of performance for acquisition or farm-in opportunity analysis.

STAGE 1B Exploration Support

Managing Data Acquisition and Quality Control

Good data is critical to unconventional gas exploration and evaluation.

RPS offers support to geoscience operations in planning, permitting, positioning and quality control (QC) of seismic acquisition, management of the interpretation process

Land Access, Environmental Impact Assessments and Planning Approvals

RPS can supply staff and approvals management services required for an exploration programme, including land access, surveying, EIAs and applications, cultural heritage assessments, seismic pegging teams, as well as Health, Safety, Environmental and Risk Management (HSERM) services.

Well Site Geological and Log QC Services

New plays depend heavily on the accurate description of the cap rock and potential pay zone, fit-for-purpose coring programs with proper handling of cores, complete analysis and detailed core description, as well as DST or injectivity test planning and analysis.

STAGE 2 Delineation and Pilot Testing Programs

Design of Delineation Wells

Many unconventional gas plays depend on properly designed and executed well completions. The tight rocks and shales need high pressure fracture stimulations for which the well tubulars, treating equipment and fluids must be properly designed and pre-qualified. RPS is focused on the dissemination of this expertise from our centre of excellence for well engineering in Calgary, Canada.

Resource Evaluation

Pilot testing programs need to be properly planned and evaluated to establish commerciality. Knowledge of how productivity may vary within a play based on reality checks against reasonable analogies, adds credibility to theoretical estimates of future performance.

Water Supply Management

Unconventional gas delineation poses operational challenges in the supply of water for field operations, the disposal of treating fluids and associated permitting and aquifer monitoring requirements.

RPS helps clients identify and implement cost-effective water treatment for use, disposal or re-injection, and compliance plans for water-dependent ecosystems.

Unconventional gas is generally in the first three stages of the E&P process that precede Front End Engineering and Design (FEED) and Field Development Planning (FDP).

Evaluation of Shale and Tight Sand Gas Potential for Frontier Basins in Australia and India

RPS has undertaken both screening level studies for proponents and data room visits on behalf of potential investors.

Where the results of the preliminary analysis were positive, the study was expanded to include the determination of prospective resources in specified areas.

Shale Gas Exploration Potential and Resource Evaluation of European Basins

RPS has carried out fully integrated multi-disciplinary studies of several UK and European basins for exploration ‘sweet spot’ delineation and evaluation of hydrocarbon resources for Competent Persons Reports.

Low Permeability Unconventional Study

RPS was commissioned by an international oil company to undertake a Low Permeability Unconventional (LPU) study with the objective of identifying where the largest gas reserves and production would be located in 20 years.

The first phase was to catalogue and evaluate all U.S. unconventional plays, including productivity characteristics, geologic setting and ultimate recovery.

The objective of the second phase was to apply the knowledge of the U.S. plays to other areas and basins worldwide.

Resource-to-Reserves Evaluation

RPS was commissioned to undertake a study to evaluate the tight gas resource-to-reserves conversion for various operators in the Piceance Basin, Colorado.

We also estimated the impact of development plans on earnings.

Barnett Shale Acreage Evaluation

RPS examined public records, interviewed people active in the area and purchased, reprocessed and interpreted seismic data critical to characterising the Barnett shale potential on the edge of the Forth Worth Basin. This work led to the client contracting RPS to obtain a lease/farm-out agreement that best met their needs.
