  • PROCEEDINGS, INDONESIAN PETROLEUM ASSOCIATION Thirtieth Annual Convention & Exhibition, August 2005 THROUGH TUBING SAND CONTROL WITH VENT SCREEN
    2011
    Co-Authors: Bonifasius Muryanto
    Abstract:

    Following excessive sand production from the HB-1 Well in the Bekapai Field, the oil production from the central panel of the main zone was stopped. A costeffective sand control solution was needed to reproduce that zone since Bekapai field is a mature field with mediocre gain expected. This solution will have to overcome several challenges which are: • Through tubing operation with an old completion (more than 20 years old) with a very small ID • Dual annulus configuration: sand control solution to be applied in a concentric configuration of 5”1/2 blank pipe inside a 9”5/8 casing. • Small tripod platform: lifting and handling operation directly from Crane Barge due to limited working space.

    Abstract:

    Following excessive sand production from the HB-1 Well in the Bekapai Field, the oil production from the central panel of the main zone was stopped. A costeffective sand control solution was needed to reproduce that zone since Bekapai field is a mature field with mediocre gain expected. This solution will have to overcome several challenges which are: • Through tubing operation with an old completion (more than 20 years old) with a very small ID • Dual annulus configuration: sand control solution to be applied in a concentric configuration of 5”1/2 blank pipe inside a 9”5/8 casing. • Small tripod platform: lifting and handling operation directly from Crane Barge due to limited working space. The solution chosen was to utilize a Vent screen combined with a high rate water pack. This method is a compromise between an expensive frac-pack operation and a low productivity classic gravel pack operation. The Vent Screen method uses two screen assemblies separated by blank pipe (Figure 2). Proppant is packed around the lower screen and most of the blank pipe. The differential pressure created on the screen annulus will create a unique flow path. The high rate water pack is aiming to by-pass only the damaging zone in the near wellbore to maximize productivity. The job design objective was to optimize productivity through the vent screen by an enhanced design of the perforation and pumping method. Prior to starting the job, a tubing wash and a sand cleaning were * Total E&P Indonesie performed. Dual wire wrapped screens were deployed with a Coil Tubing Unit and set on top of the plug covered by cement. A high rate water pack treatment was performed by pumping the proppant using VES (Visco Elastic Surfactant) carrier fluid. After Nitrogen off-load, the well was able to produce oil at the same production rate as before shut in and without any sand trace or proppant flow back indication on surface. The break even point was reached after less than 5 months. This paper will discuss the design method, job execution and lessons learned from this operation. INTRODUCTION Bekapai Field is a mature oil field which is prone to sand production. This is the case of the HB-1 well which had been shut in due to excessive sand production. This string was producing from the main layer with production ranging from 400 – 600 bopd. A sand control method was applied to regain production from that zone. A Thru-Tubing Sand Control (TTSC) method was chosen as a compromise since the short string was still producing and a Heavy Work-Over cost was not justified by the remaining reserves in the main layer Production and Intervention History HB-1 well was drilled and completed as a dual string completion in June, 1983. The Short String produces the upper layer with a constant production rate. The Long String was initially producing the lower layer through a gravel pack before permanently abandoned by cement squeeze. The Main layer was then perforated without sand control. High production was achieved during 6 months, but the production declined rapidly after water break through and died 4 months later. Since then, no other well produces from © IPA, 2011 30th Annual Convention Proceedings (Volume 2), 2005

  • Numerical Offshore Tank – TPN
    2015
    Co-Authors: Daniel P. Vieira, Edgard B. Malta, São Paulo, Fabiano P. Rampazzo, João Luis, B. Silva, Eduardo A. Tannuri
    Abstract:

    In ocean systems composed by two or more closing floating bodies, coupled hydrodynamics effects must be considered. Dynamic positioned systems (DP), for example, need an accurate determination of environmental forces to guarantee a safe operation. This work presents a numerical methodology, using the WAMIT code, to evaluate both first order motions and mean drift forces of a system composed by a DP Crane Barge operating close to a turret-moored FPSO. The first order wave forces were evaluated using the code standard method. The second order forces (or mean drift forces) were obtained using the alternative control surface method. The work discussions are centered on the effects of FPSO presence on DP Barge hydrodynamics. Two relative positions between vessels were evaluated as well as three FPSO drafts (full, intermediate and ballasted). The effects of wave incidence angle were also discussed

  • Minimum Energy DP Heading Control: Critical Analysis and Comparison of Different Strategies
    Volume 1: Offshore Technology, 2013
    Co-Authors: Michel R. Miyazaki, Eduardo A. Tannuri, Allan C. De Oliveira
    Abstract:

    DP offshore operations require that the vessel reference point is controlled in relation to a fixed reference frame. In some cases, the heading is allowed to change, searching for an adequate angle in which the environmental conditions induce small loads in the hull and minimum DP power is required to keep the position. This DP mode is usually referred as “weathervane control”.There is no exact method to determinate the minimum energy heading of a vessel in real-time with only the sensors available in a DP system. Therefore, some control strategies were developed in order to control the vessel heading, and estimate the optimal value.This paper addresses the analysis of the final equilibrium heading of several published weathervane control strategies for two different DP vessels: a typical DP tanker and an asymmetrical DP Crane-Barge. A static procedure is used to calculate the final heading and the DP power and thrust demand for each controller.Several environmental combinations of wind, current, local sea-waves and swell are considered, with a systematic variation of the intensities and the direction of the environmental agents.For non-aligned environmental agents, differences in the final heading are verified for the zero yaw and zero sway strategies. These headings are also compared to the exact minimum power heading, obtained by an optimization procedure considering the DP thrust allocation.Copyright © 2013 by ASME

  • Motion-based wave estimation: Small-scale tests with a Crane-Barge model
    Marine Structures, 2012
    Co-Authors: Eduardo A. Tannuri, Alexandre N. Simos, João V. Sparano, Vinicius L. F. Matos
    Abstract:

    Abstract This paper provides additional validation to the problem of estimating wave spectra based on the first-order motions of a moored vessel. Prior investigations conducted by the authors have attested that even a large-volume ship, such as an FPSO unit, could be adopted for on-board estimation of the wave field. The obvious limitation of the methodology concerns filtering of high-frequency wave components, for which the vessel has no significant response. As a result, the estimation range is directly dependent on the characteristics of the vessel response. In order to extend this analysis, further small-scale tests were performed with a model of a pipe-laying Crane-Barge. When compared to the FPSO case, the results attest that a broader range of typical sea states can be accurately estimated, including crossed-sea states with low peak periods.

  • Station Keeping and Propulsive Performance of a DP Crane Barge Close to a FPSO: A Comprehensive Set of Experimental Tests
    Volume 1: Offshore Technology, 2012
    Co-Authors: Eduardo A. Tannuri, L. Moratelli, Vinicius L. Vileti, João Luis B. Silva
    Abstract:

    DP Crane Barges operate in close proximity to FPSO (Floating Production Storage and Offloading) during lifting operations. This operation is critical since small variations of the relative position may result in collision between the bodies or large motion of the lifting load. The hydrodynamic interactions between the units are an important effect that must be considered in the analysis of those operations. The interactions are an intricate problem that cannot be modeled analytically in an appropriate way. Hence, experimental and numerical tools are applied for the definition of the environmental conditions for a safe operation or the optimal relative positioning between the vessels.A research project conducted by Petrobras in cooperation with Brazilian universities aims to develop and to validate numerical tools for aiding the design and analysis of the DP lifting operations. They are based on dynamical time-domain simulations of the operation and can be used for predicting several parameters of the operations. The experimental tests that will be used for validating this numerical model, concerning the DP performance when the Crane Barge is close to a FPSO, are presented in this paper. The tests were conducted in an ocean basin using the model of a moored FPSO and the DP Crane Barge. The station keeping ability (relative motion) and the performance of the propulsive subsystem of the DP Crane Barge (power and thrust utilization parameters) are measured. Several relative positions and wave conditions were considered.Copyright © 2012 by ASME
