“…In field applications, different types of swellable elastomers are used at different depths of the same well, or in different wells. Extensive amount of research has been carried out for material and mechanical characterization of swellable elastomers in virgin or vulcanized form, as well as in borehole conditions (Zeidan et al 2018;Al-Yami et al 2008). Some researchers have tested laboratory-size elastomer samples under different temperatures and saltwater concentrations (Patel et al 2019;Qamar et al 2009Qamar et al , 2016Pervez et al 2012).…”

In the petroleum industry, packers refer to the components/products which are used to isolate one section in a formation from others, or to isolate the outer section of a production tubing from the inner section, which may be a casing or a liner or the wellbore itself. Mechanical packers are installed through some form of tubing movement. Permanent packers are low in cost and provide better seal. Retrievable packers have lower sealing capability but are re-usable after repair, and therefore expensive. More innovative packers made of swellable elastomers are rather new. These elastomers swell when they come in contact with different types of fluids (mostly water and oil). Like a casing, these new packers are lowered to the desired depth and allowed to swell before production or injection operations begin. Various studies have been published about the swelling and mechanical response of these elastomers. However, many questions remain about the sealing performance of swell packers, and their effectiveness in actual wellbores of rough and random profiles. This paper describes the design and development of an experimental unit for performance testing of a mix of inert and swelling elastomer seals under realistic well conditions. Actual swell packers and petroleum tubulars are housed in a concrete block that replicates open-hole and cased-hole wells through layers of varying roughness. This is a one-of-its-kind unit providing full-scale demonstration about the working of swell packers against outer casing or rock formation in a wellbore. It is also a complete testing apparatus to investigate the behavior of swell packers made of fast-swell and medium-swell elastomers, and how they seal off irregular boreholes. This work can provide basic understanding and visual corroboration to petroleum engineers and students, swelling elastomer application developers, and academic and research personnel.

Existing technologies currently utilised in well, reservoir & facility management (WRFM) to gain detailed insights into the issues affecting the petroleum production system are discipline specific, hence focus is mainly given to analysis of each component of the production system separately. These isolated functional analyses are sometimes based on inconsistent datasets which may lead to erroneous diagnosis of production problems and could ultimately result in failed well interventions if not rigorously checked via multi-disciplinary reviews. The multi-disciplinary nature of WRFM practice requires that the discipline-specific interpretations of the well, reservoir & facility models be integrated to eliminate potential inconsistencies and improve quality of interpretations. This paper presents a new technology for WRFM workflow integration based on the principle of integration of interpretations. The benefits of integration of interpretations in WRFM data democratisation and process digitalisation are also highlighted.

Production in a green, heavy oil field in Northern Kuwait with limited production history is in a fast track delivery to increase production in the short term. A fast but insightful evaluation was required to identify field-wide productivity enhancement opportunities needed to increase oil production. A parametric analysis methodology was applied to a "typical well" to first obtain the factors that limit the well's production thorough understanding of the overall well potential, to finaly identify inflow and outflow enhancement opportunities. Nodal analysis based on Darcy inflow model was utilized and multiple sensitivities were run for parameters prevoisuly identified. The parameters were expanded in value considering possible technical solutions applicable but not limited to: completion and perforation design, artificial lift performance and surface equipment, in order to determine technical limits applicable for each parameter using a combination of proven and novel technologies. The parametric analysis helped to identify inflow and outflow enhancement opportunities (from the sand face to the separator), including but not limited to: well stimulation, re-perforation, pump efficiency and back pressure reduction. The range of the theoretical oil rate improvement identified from the analysis was from 20 to 50%. Based on the model results, additional resources were alloactred for a more detailed validation and study work using simulation. The parametric modeling approach was subsequently crosschecked on individual well reviews, where detailed inflow and outflow evaluations were conducted resulting in good agreement in terms of value in production gains. The applied methodology showed to be a valid and fast track approach, readily to identify field-wide production issues and opportunities, particularly at the start of field production. The results obtained from this study provide a comprehensive approach to understand how well design, engineering decisions and field operational practices will impact well productivity. The methodology can be easily replicated by engineers in similar fields.
