Production Technology(Upstream)

PRODUCTION TECHNOLOGY 1. Introduction This chapter covers the intersection technology looking at of Berlian East theatre of operations field. Studies and reviews comprising the aspect from bottomhole up to the intumescehead atomic number 18 included in this section. The puff up completion design rivet on subway system selection, material selection and go across hole equipment. The main objectives of the drudgery technology design argon to: ? Provide a full and effective design of a well completion for in all producers. ? Maintain well integrity during the proceeds life plot of grounds increase the recovery. ? Allow future intervention and recompletion for any production sweetening activities. 2. sand Control Strategies 2.1 Sand Condition Analysis ground on the well test result for BE 1, BE 3 and BE 4, gritstone production traces can be observed at surface with a maximum drawdown of 278 psi, cd psi and 660 psi respectively. Although in that res pect is no severe trustworthy sense production in the sample, high drag commit due(p) to high water supply cut is expected to intellect near-wellbore back grain migration. at that placefore, sand exclusion is proposed for all completions. 2.2 Sand payoff on Water Injection Since sand production problems are predicted(unconsolidated sand formation) for BE field, downhole sand control is inevitable to all water injectors planned. Based on the previous lessons, there is a SPE to pardon the lesson learnt. In the SPE paper 64297 written by Statoil Norway, the operator having constitutional losses of injectivity over short finish of time from a series of water injectors concluded that: * There is a kindred between well shut-in and injectivity losses, in which under no flow conditions corresponding to shut-in periods, the contention around the well is too weak to sustain the stress, thence failed. * The permeability heterogeneousness of the formations causi ng cross-flow during shut-in periods, hence ! allowing sand to be produced especially across the perforated interval. * The particles that are ineffectual to settle in...If you deficiency to get a full essay, mold it on our website: BestEssayCheap.com
