TX 75083-3836, U.S.A., fax 01-972-952-9435. AbstractRepresentative reservoir fluid sampling and characterization has become increasingly important over the years. With exploration, appraisal and development activities moving into marginal fields and more challenging environments, accurate fluid characterization becomes more critical. This can be said for the formation tester, DST and multiphase sampling and fluid characterization environments with the most challenging area in recent years arguably being the multiphase environment. Multiphase flow meters have been accepted for several years now by the industry. Their use in permanent or well testing applications has been growing rapidly. In many cases, multiphase flow meters have replaced the separator for flow rate evaluation, but some fundamental needs from operators were not addressed properly, such as the ability to collect representative samples for phase-behavior characterization. Moreover, metering accuracies has been questionable in many cases (at very high GVF or in wet gas conditions, high pressure or /and high temperature). This paper focuses on the Multiphase Active Sampling Device Service (MASS), a fluid sampling and analysis service that can be provided with the Vx * multiphase metering technology with the objective of collecting representative samples, isolating and analyzing each fluid phase, and providing data from the analysis as input to the Vx* acquisition software data to obtain more accurate flow rates. The collection of phase representative samples also opens the opportunity for a full recombination PVT study to be performed using the improved recombination ratio at line conditions from the multiphase flow meter. This dedicated multiphase fluid sampling and analysis system, combined with Vx technology provides a comprehensive and accurate set of fluid properties for improved flow-rate measurement accuracy compared to conventional systems.

This paper presents the experiences of well clean-up operations carried out in the development wells of Akpo deepwater field. Akpo is located 135 km offshore Nigeria in 1400 m of water depth. The reservoirs consist of faulted, unconsolidated, turbiditic channel and lobe sands with complex architecture. The fluids in each reservoir are near-critical. The field is currently producing about 175,000 barrels of condensates per day. Current sand control techniques are Frac-Pack (FP), Stand Alone Screen (SAS) and Expandable Screen (ES). Early data acquisition during well clean-ups was essential in other to optimise the development strategy, ensure a production ramp-up in line with expectation and reduce remaining uncertainties which were mainly linked to sand communication within channel complexes, fluid behaviour, and faults behaviour (seal or conduit). The paper covers the clean-up design, execution, operations monitoring, data acquisition, and fluid sampling, along with the challenges and constraints encountered in the process for the different wells. It describes how the challenge of hydrates formation, exacerbated by the deepwater environment and peculiar nature of the reservoir fluid, was handled to ensure successful well clean-ups. It also gives an example on how the early data acquisition program impacted important field development decisions.
