Managing the field

Field Indirects - If the Owner acts as construction manager, the Field Indirects should not exceed 10% of the total labor and subcontract columns. If construction management is done by a contractor, follow guidelines in Section 19.9.

The field development plan s prime purpose is to serve as a conceptual project specification for subsurface and surface facilities, and the operational and maintenance philosophy required to support a proposal for the required investments. It should give management and shareholders confidence that all aspects of the project have been... 

Introduction and commercial application Safety and the environment have become important elements of all parts of the field life cycle, and involve all of the technical and support functions in an oil company. The Piper Alpha disaster in the North Sea in 1988 has resulted in a major change in the approach to management of safety of world-wide oil and gas exploration and production activities. Companies recognise that good safety and environmental management make economic sense and are essential to guaranteeing long term presence in the industry. 

Introduction and Commercial Application The reservoir and well behaviour under dynamic conditions are key parameters in determining what fraction of the hydrocarbons initially in place will be produced to surface over the lifetime of the field, at what rates they will be produced, and which unwanted fluids such as water are also produced. This behaviour will therefore dictate the revenue stream which the development will generate through sales of the hydrocarbons. The reservoir and well performance are linked to the surface development plan, and cannot be considered in isolation different subsurface development plans will demand different surface facilities. The prediction of reservoir and well behaviour are therefore crucial components of field development planning, as well as playing a major role in reservoir management during production. 

It Is important to know how much each well produces or injects in order to identify productivity or injectivity changes in the wells, the cause of which may then be investigated. Also, for reservoir management purposes (Section 14.0) it is necessary to understand the distribution of volumes of fluids produced from and injected into the field. This data is input to the reservoir simulation model, and is used to check whether the actual performance agrees with the prediction, and to update the historical data in the model. Where actual and predicted results do not agree, an explanation is sought, and may lead to an adjustment of the model (e.g. re-defining pressure boundaries, or volumes of fluid in place). 

The operations group will develop general operating and maintenance objectives for the facilities which will address product quality, costs, safety and environmental issues. At a more detailed level, the mode of operations and maintenance tor a particular project will be specified in the field development plan. Both specifications will be discussed in this section, which will focus on the input of the production operations and maintenance departments to a field development plan. The management of the field during the producing period is discussed in Section 14.0. 

Introduction and Commercial Application The production decline period for a field is usually defined as starting once the field production rate falls from its plateau rate. Individual well rates may however drop long before field output falls. This section introduces some of the options that may be available, initially to arrest production decline, and subsequently to manage decline in the most cost effective manner. 

The field may enter into an economic decline when either income is falling (production decline) or costs are rising, and in many cases both are happening. Whilst there may be scope for further investment in a field in economic decline, it should not tie up funds that can be used more effectively in new projects. A mature development must continue to generate a positive cashflow and compete with other projects for funds. The options that are discussed in this section give some idea of the alternatives that may be available to manage the inevitable process of economic decline, and to extend reservoir and facility life. 

The physical reasons for the benefits of EOR on recovery are discussed in Section 8.7, and the following gives a qualitative description of how the techniques may be applied to manage the production decline period of a field. 

The field of chemoinformatics was not founded, nor was it formally installed. It slowly evolved from several, often quite humble, begmnings. Scientists in various fields of chemistry struggled to develop computer methods in order to manage the... 

A multiple chent study may serve many useful purposes to company management. It may act as a primer for intensive study of a narrower part of the market, a guide to deciding whether to expend R D effort in the field, or a guide to deciding whether to acquire a company already in the field. The independent study can also resolve conflicting opinions within different departments of the chent company. Finally, the cost of a multiple chent study is usually lower than the cost of a comparable study by a chents in-house personnel. 

Besides being slower, anaerobic treatment is more difficult to manage and can generate by-products that are more mobile or toxic than the original compound, for example, the daughter products of TCE, ie, dichloroethenes and vinyl chloride. It requires a longer acclimation period which means slower startup times in the field. The microbial processes are less well understood, and hence, ate less controlled than for aerobic systems. 

Much of the current activity in the field of sohd waste management, especially with respect to hazardous wastes and resources recoveiy, is a direct consequence of recent legislation. Therefore, it is important to review the principal legislation that has affected the entire field of solid-waste management. 

Review Follow-up Verification In addition to someone tracking the follow-up through progress reports, responsibility should be assigned to verify that any process changes were ac tuaUy made in the field. This verification can be done by a review team as part of a process pre-start-up review. It could also be part of the project team management responsibihty or assigned to a particular functional (i.e., safety and loss prevention) representative. The closure of the review process is complete once implementation is verified. 

For smaller projects, the field team leader and project manager will likely be the same person. 

Security issues involving access controls are typically line management responsibilities. However, it is not unheard of to have the SSHO in charge of site access or other security-related matters. However, if the field team leader or site supervisors are in charge of access issues or other security matters, they should always strive for SSHO participation. The nature of a project may warrant assigning a member of the site security staff to the project team. Key duties of the security officer may include the following ...
