Title: Successful high angle drilling in the Statfjord Field

Abstract

The original drilling design criteria for Statfjord field development set an upper limit on wellbore inclination of 60/sup 0/. This figure was derived by considering the special drilling problems found on Statfjord and technological limitations. By developing engineering operational procedures and introducing new technology, wells can be drilled routinely at sail angles between 60/sup 0/ - 70/sup 0/. This paper, therefore, elaborates upon the special drilling problems encountered in the area and describes engineering and operational solutions which were developed to extend the maximum reach of wells. In addition, it describes the evolution of drilling on Statfjord and documents the impact of advances.

  • An elemental model was used to investigate the effect of using the existing crestal gas injectors in the statfjord Fm at the Statfjord Field for additional updip water injection. The element was extracted from a history matched full field model and refined.The simulations gave accelerated production and increased oil recovery of approximately 5% with updip water injection, primarily because of better pressure maintenance, better sweep of lower parts of the formation and less problems with gas production constraints. Sensitivities on selected parameters did not indicate anything in disfavor of updip water injection. Full field simulations have confirmed the potential ofmore » updip water injection, and the scheme is found to fit very well into the overall Statfjord Field strategy.« less
  • Gravel packing can be successfully performed on high-angle wells (70/sup 0/-80/sup 0/) when special consideration is given to the completion design and details of field procedures and practices. Through analysis and modification of current techniques and research done on full scale models, Chevron experimented with and developed several techniques to successfully gravel pack high-angle wells. The high-angle gravel packs were performed utilizing the following criteria: solids free completion fluids, low-side perforating, modified screens, combination tools (circulating pack), maximum tailpipe (washpipe)-liner ratios, medium viscosity carrier fluids, maximum pumping rates, and special attention to quality control. Sand-out pressures, subsequent pack tests, quantitymore » of gravel placed (percent packed volume) and extended flow tests of up to 20 MMCFD have proven the success of the design and procedures implemented.« less
  • The Statfjord field is the largest oil field discovered in Europe, with initial recoverable reserves of more than 3 billion bbl of oil and 3 tcf of gas. The field lies 120 mi offshore from Bergen, Norway, in 475 ft of water, and is being developed using three Condeep platforms with a combined production capacity of more than 800,000 bbl/day. To date, approximately 70 of a planned 99 development wells have been drilled. The main hydrocarbon reservoirs are Mesozoic sandstones of the Brent Group and Statfjord Formation. Both units exhibit excellent reservoir properties, with porosities ranging from 20 to 35%more » and permeabilities up to several darcys. A sandstone unit within the intervening Dunlin shales is under study for future development. Pressure maintenance is achieved in the Brent Group by water injection and in the Statfjord Formation by high-pressure miscible gas displacement. Reservoir simulation studies and regulator formation-pressure monitoring guide the drilling sequence and, coupled with field geology, dictate the selection of well locations and completion intervals. Placement of updip wells along the eastern flank of the field, where the Brent and Statfjord reservoirs are erosionally and tectonically thinned, is determined by mapping the start of truncation for each reservoir. Total oil recovery is enhanced by initially completing wells in stratigraphic units of less than optimal porosity and permeability to ensure these zones are not bypassed.« less
  • Rapidly increasing costs associated with North Sea development have produced an environment in which good field development planning is imperative. Reservoir management is the keystone of any plan. This study reviews the geology of the Statfjord Field and describes the latest reservoir simulation techniques being used for the evaluation of producing alternatives. The Statfjord Field is comprised of 2 geologically complex reservoirs - the Brent and the Statfjord. The overall development plan calls for pressure maintenance by waterflood in the Brent and a combination gas and waterflood in the Statfjord. The first platform, Statfjord A is in place in themore » field and the second, Statfjord B, is under construction. These 2 platforms will go in the center and southern part of the field, respectively. The development program for the northern part of the field and the optimum utilization of the associated gas have not been resolved. The simulation approach chosen employs several 3-dimensional cross-section models to evaluate the impact of reservoir property variations and water and gas coning and cusping.« less
  • A geological/reservoir engineering modelling study of the Brent field's Statfjord Formation reservoir is outlined as follows: it describes the geological characteristics of the reservoir, it illustrates how these features were incorporated into a detailed (32 layer) computer simulation model, and it summarizes some of the main conclusions concerning the nature of fluid flow through this heterogeneous reservoir in relation to possible field development scenarios. The study demonstrates how complex, threedimensional reservoir heterogeneity can be modelled with the latest type of large-capacity computers, such as the CRAY. Since these models are geologically more realistic, they can provide a better illustration ofmore » reservoir behaviour, which will improve performance prediction.« less
