“…Target conditions for Statfjord LTPF formulation were determined based on various considerations of the field conditions (Haugen et al 1988) and our experience in LTPF design. Based on calculations and phase behaviour studies, Staffjord stock tank oil has an approximate EACN of 7.8-8.0.…”

A preliminary laboratory study was initiated in 1991 to assess the potential of Low Tension Polymer Flood (LTPF) in the Statfjord Field Upper Brent Formation. On the basis of phase behaviour and compatibility experiments, four formulations were identified for further evaluation and a live oil core flood test was conducted to assess the oil recovery potential of one formulation under reservoir conditions. Encouraged by the initial laboratory results, a three-step LTPF process design strategy was followed. A target area of the reservoir was identified, the performance of the waterflood in this area was history-matched using the LTPF simulator and a predictive simulation of several LTPF application strategies was performed.The chemical flood simulator, BPOPE, was first employed to match the laboratory core flow test by incorporating the LTPF characteristics measured. Following this conditioning, it was then used to assess the application of LTPF in the formation selected. A variety of perforation strategies, LTPF slug sizes and operating conditions were tested, all with reservoir cooling due to the injection of cold sea water.The modelling shows LTPF to be sensitive to slug size in particular, to surfactant phase behaviour and to adsorption loss levels. It was concluded that the LTPF process could be applied to the Tarbert formation, to yield additional recovery. However, an optimization is required to make the LTPF process attractive for implementation. This paper presents the essential phase behaviour data, the results of the live oil core flow test, and discussion of the computer simulation approach and the results.

The Statfjord field, the largest North Sea oil field, has been on production since 1979. We think that production decline is imminent; however, oil production was close to a record for the field in 1991. This paper discusses the reservoir drainage strategy; the situation after 13 years of production; and short-and long-range perspectives for further field development, which includes a high well activity level to maintain the well production potential. Most of the wells drilled and scheduled are either horizontal wells or extended-reach wells, extending toward the flanks of the field. A large effort has been put into mapping remaining reserves by developing detailed reservoir simulation models. The production and well activities have been optimized on the basis of the results from the new models. Exploitation of business opportunities, such as processing of third-party crude from tie-in and subsea satellite fields and external gas storage, gives a new perspective for an oil field on production decline. In addition to these long-range plans, studies of such recovery methods as water-alternating-gas (WAG), surfactant, and polymer injection are continuing.

Many alternatives arise during the development of major oil and gas fields. Resetvoir simulation has a firmly established role in helping to select which of these alternatives will give the optimum development. This is especially true in the North Sea where development and operating costs are relatively high and it is cost effective to study options in detail before proceeding in the field.General reservoir simulation principles are now well known by resetvoir engineers but they are summarised in this paper as an introduction for a wider audience.A case history is presented which shows how reservoir simulation has been important at all stages in the development of BP's Magnus field. Figures are presented to show how estimated Magnus field reserves have changed with the acquisition of new data and improved interpretation techniques. Reserves histories for other major North Sea fields are also discussed."' Fonnerly with BP Exploration Company References and IDustrations at end of Paper.
