In 2009, Lukoil installed inflow control devices (ICDs) in three horizontal wells in the Sredne-Sercheyusskoe anticline of Yuzhno-Shapkinskoe oilfield. The successful installation of the lower completion will describe the planning and design through detailed near wellbore modeling pre and post drilling. The latter used LWD measurements to update the model and redesign the completion to address the actual wellbore heterogeneity to optimize future production in terms of production acceleration and mitigation of more mobile fluids through inflow balancing. In addition, to ensure production contribution from heel to toe through the use of an optimized ICD completion, an acid treatment was also executed in two wells which further improved productivity of the well by successfully removing formation damage and possible debris barrier plugging. The ICD completion offered a means to balance the outflow of acid distribution across heterogeneous wellbores. The predesign acid job and post analysis will be presented and discussed.

Unconventional hydrocarbon resources are becoming more and more important to the overall world energy picture and Russia is no exception. Heavy oil has long been an acknowledged asset but renewed efforts to replace the aging conventional resource base are focusing increased attention on this often neglected resource. Many of Russia's heavy oil fields were discovered 20-30 years ago and the formation evaluation data from these old exploration wells is often scanty. Quality fluid samples, especially, were almost impossible to obtain. Aside from the very high viscosity that almost precludes fluid movement, the reservoirs were often either unconsolidated sands with low failure strengths or, in rare cases, carbonates with extensive vug and fracture networks. However, with a renewed focus on these reservoirs, quality formation samples are a necessity.In this paper we show successful approaches using wireline formation testers to acquire heavy oil sample in two Lukoil fields in the Timan Pechora region: Varandeyskoe and Zapadno-Lekeiyaginskoe. These fields have many differences but two important similarities: very heavy oil and a vital need to understand the fluid properties.
