Abstract

Enhanced Oil Recovery (EOR) is a tertiary recovery which requires relatively a high cost of CAPEX and OPEX. The current EOR technique is generally stand alone and injected into single reservoir layer without contributing to the other layers (unconnected reservoir layer). For this reason, a breakthrough of low cost EOR technology (CAPEX & OPEX) is needed, especially since oil prices tend to fall low. Vibroseismic EOR is one of the EOR methods (categorized as mechanical EOR) that is inexpensive, fast response / yield, high mobility (can be moved to another place), environmentally friendly, and could be combined with the waterflood method or other EOR methods to get more effective and optimal result. However, the research & implementation on Vibroseismic EOR are still limited. The paper describes the pilot test of Vibroseismic EOR technology in Tempino Field. The initial stage is to select the suitable field for implementation Vibroseismic EOR. Then, the rock & fluid properties of the selected field are tested and examined by vibration and stimulation in the laboratory to obtain optimum frequency of 20 Hz S waves (circular / transverse) and 35 Hz P waves (longitudinal). The field scale-up process is carried out by measuring or testing field parameters called Vibroseis Field Parameter Test (VFP Test). VFP Test results get the optimum frequency of S and P waves of 20 Hz using 3 trucks and drive level 70% with amplitude value up to 0.024 rms (root mean square). Through the EOR vibroseismic method, the truck is the source of vibrations on the surface will generate acoustic waves propagating through the rock (subsurface) throughout the reservoir layer within the wave penetration range, generally reaching a depth of 6500 ft depending on the amplitude / power source of vibration, thickness of weathered layer, and rock type. The waves that reach the reservoir will affect the rock & fluids properties. The pilot test results on production wells showed a positive response within 1 month after vibration, especially those around the existing injection wells which the permeability was relatively good. The increased production accumulative of 10 (ten) monitoring production wells about 8% and withhold declining rate up to 20% from base case. Oil drainage around production wells and drainage direction are confirmed by changes in hydrocarbon saturation maps through passive seismic techniques measured before, during, and after vibration. The results of this pilot test show that Vibroseismic EOR technology is very promising to be developed to the full-scale stage and implemented in other areas.
在印尼苏门答腊Tempino油田进行的震震提高采收率技术先导试验中,突破了低成本、快速产出的提高采收率技术
提高采收率(EOR)是三次采收率,需要相对较高的资本支出和运营成本。目前的EOR技术通常是独立的,注入到单个油藏中,不会对其他层(未连通的油藏层)产生影响。因此,低成本EOR技术(CAPEX & OPEX)的突破是必要的,尤其是在油价趋于下跌的情况下。振震提高采收率是机械提高采收率的一种方法,具有成本低廉、响应速度快、采收率高、移动性强(可转移到其他地方)、环境友好等特点,可与水驱法或其他提高采收率方法相结合,以获得更有效、更优的采收率。然而,振震提高采收率的研究和实施仍然有限。本文介绍了振震提高采收率技术在坦皮诺油田的中试情况。初始阶段是选择适合实施振震提高采收率的油田。然后,在实验室中通过振动和刺激对选定油田的岩石和流体特性进行测试和检查,以获得最佳频率为20 Hz S波(圆形/横向)和35 Hz P波(纵向)。现场放大过程是通过测量或测试称为可控震源现场参数测试(VFP测试)的现场参数来进行的。VFP试验结果表明,在3辆卡车、70%驱动水平下,S波和P波的最佳频率为20 Hz,幅值可达0.024 rms(均方根)。通过EOR振动地震方法,卡车是表面上的振动源,将产生声波在波的穿透范围内通过岩石(地下)传播到整个储层,通常达到6500英尺的深度,这取决于振动的振幅/功率源、风化层的厚度和岩石类型。到达储层的波将影响岩石和流体的性质。对生产井的中试结果表明,振动后1个月内有正响应,特别是在现有注水井周围,渗透率相对较好。10口监测生产井的产量累计增加了约8%,并从基本情况中保留了高达20%的下降速度。通过被动地震技术在振动前、振动中和振动后测量油气饱和度图的变化,可以确定生产井周围的排油情况和排油方向。该试验的结果表明,振震提高采收率技术非常有希望发展到全面阶段,并在其他领域得到应用。
