CCL 2010 service offer

  1. 1. Caspian Consultants Field Development Planning
  2. 2. The Approach Caspian Consultants will guide your company to identify and assess appropriate and profitable field development methods for your field(s). We will also propose the optimal development concept from a business case perspective for the selected methodology and mature this option, including overseeing necessary laboratory and field tests to facilitate a final investment decision. Field (re)development is done in four phases- with specific deliverables and decisions at each point. Caspian Consultants will lead your company through these planning stages, providing clarity around required steps and the incremental value associated with proposed development activity. Field development planning is in 4 phases: Phase 1: Screening Phase 3: Concept select Phase 2: Concept identification Phase 4: Front end engineering design Field Development Planning Phase 1: Screening The objective of the screening phase is to determine which redevelopment methodologies are applicable for the client’s field and propose a preferred option. This phase is initiated by framing the project at the client’s office and gathering relevant, quality controlling and restoring data. During the framing, the client will share the field development philosophy, history and operations, as well as the commercial framework within which the field must be profitable. Caspian Consultants will evaluate available geological, petrophysical, dynamic, well and facilities data to help formulate the project timeline, determine if significant gaps exist. 1
  3. 3. Back in Caspian Consultants’s offices, our staff will apply their broad expertise to rapidly assess several (re)development methods including optimized water flood, polymer flood and chemical (ASP) flood, as appropriate. Important parameters for consideration in the analysis include reservoir, crude and aquifer properties, including reservoir temperature, crude viscosity, reservoir permeability and aquifer salinity. For given methods a small dynamic simulation may be constructed to help determine field sensitivities to these parameters and estimate incremental production and uncertainty associated with the forecast. At the conclusion of this phase, a screening report will be generated and personally reviewed onsite with the client. This report will describe the methodologies evaluated, discuss their applicability to the client’s field, and estimate relative incremental production and ultimate recovery, as well as risks and uncertainties and proposed roadmap forward. The report will also propose the preferred (re)development methodology. During this consultation meeting, questions and concerns will be addressed to ensure the client can make the right decision as to whether to proceed to the next step in realizing maximum returns from the study fields. Phase 2: Concept Identification The objective of this phase is to identify development concepts for the preferred redevelopment method. The results will be delivered in a feasibility report outlining the business-case and possible concepts to achieve profitable (re)development of the field under the development method identified in phase 1. The report will be be delivered and personally reviewed with the client to ensure that all issues associated with field development, including local logistics, operations, contracts and procurement and commercial regimes have been fully considered in the identification of profitable development concepts. Maturation of different concepts will commence once the preferred methodology has been chosen. Different methodologies may be utilized to mature the concept. For example, if chemical flooding is proposed, laboratory testing to characterize phase behavior testing and surfactant compatibility will be performed. This may involve testing a suite of surfactants on the crude and formation water to identify the optimum recipe to help mobilize the most oil for production. If a field pilot has been determined to be a necessary step to mature the concept, the pilot location will be determined in this phase and assessed via dynamic simulation to determine the optimal number of wells, well spacing and type. In addition, a more detailed business case will be presented which takes into account the new production forecast from the detailed simulation, and incremental investments in wells, facilities and chemicals to help the client determine whether to pursue (re)development of the field. Phase 3: Concept Selection The objective of this phase is to determine the appropriate pilot or full field development concept. Consideration will be given to the well pattern, recipe, slug sizes, injection/production rates, well- and facilities design. The results will be presented to the client at his offices in a Concept Development Plan. This report can form the basis for the Front End Engineering work to be pursued in Phase 4. Further refinement of the forecast may be done by incorporating additional laboratory results, e.g. core-flow experiments, which yield valuable insight on relative permeability, chemical absorption rates and injectivity. If applicable, relevant field tests, single well injection test with tracer will be proposed, and if agreed, designed and managed, allowing a more robust forecast of the incremental produceable oil by indirectly measuring residual oil saturation before and 2

Phase 4: FEED Finally, the objective of phase 4 is to determine whether or not the to make the financial investment decision. To aid the client in determining this, Caspian Consultants will assist the client in selecting a front end engineering design (FEED) firm, and manage the FEED studies on the client’s behalf, ensuring that all design elements are addressed and delivered to the specified quality. These designs may include identification and selection of exotic materials and novel execution approaches. Summary Caspian Consultants will provide your company with an end-to-end service: this service includes identification and assessment and a recommendation for a field (re)development method, selection of the optimal concept to execute that redevelopment and selection and management of FEED studies to allow the client to make a financial investment decision. At each step of the way, Caspian Consultants will provide the business analysis to determine the amount of incremental production, the field ultimate recovery and the value associated with that. Furthermore, Caspian Consultants will design and oversee all relevant and agreed laboratory work and field testing which may be required to make this assessment. The advantage of Caspian Consultants is that the client gets seasoned experts providing an unbiased assessment. Caspian Consultants’s pragmatic approach delivers fast screening and scoping and recommendations designed to minimize your company’s capital exposure. Caspian Consultants facilitates transparent decision making and enables your company to make the right choice for your field. Caspian Consultants’s field development approach is proven in major oil companies and flexible, so can be applied to every size field. 3
