This paper reflects back on the major trends, successes and lessons learnt of BP's 4-D deployment over the last 20 years, and offers insights into the main considerations for developing 4-D strategy in emerging areas.Since the early 1990's, BP has been developing and deploying 4-D technologies across a range of different environments and reservoir situations. Up to the end of 2007, over 115 surveys have been acquired*, about 85 operated and 30 non-operated. This experience base represents a significant proportion of industry 4-D history, and when analysed, can offer valuable insights into developing future 4-D strategy and tactics for new fields and basins. 4-D has most commonly been used in oilfields under water-flood due to the ease of monitoring large saturation and pressure changes and the increased complexity of reservoir management, which gives the opportunity for large commercial impact. Monitoring of gas field depletion has added clear value in appropriate situations, but is much less common due to the generally simpler reservoir management issues and smaller infill programs. The dominant acquisition technology deployed has been towed streamer surveys every 2-5 years, but BP has now also installed the world's first three permanent ocean bottom cable (OBC) monitoring systems to deliver high-quality and frequent 3-D and 4-D data.4-D application is continuing to expand globally, and BP itself is currently expanding 4-D application from the historical core areas of the North Sea and Gulf-of-Mexico into regions of new and existing production, such as deepwater Angola, and Alaska respectively. Development of 4-D strategies for new areas and basins requires an assessment of both technical and commercial applicability.

BP's digital oilfield initiative, the Field of the Future Technology Flagship, has been developing and deploying distinctive operational capabilities since it's inception in 2005. This paper describes the growing track record of value delivery, achieved through pace and scale deployment. These capabilities, which continue to be developed, support a relentless drive for continuous improvement in our asset operations, aiming at delivery of significant production (100mboed BPnet) and reserve (1bnbbl) targets by 2017. We report significant progress toward meeting these targets and highlight new key lessons from our growing body of experience.The Field of the Future concept is now a routine part of how BP builds projects and operates fields across much of our portfolio. It impacts a significant and growing proportion of net production and routinely supports >80% of our top 100 wells. A range of monitoring, analytical, optimization and collaborative solutions are applied according to asset needs and value opportunities.The in-house solutions have delivered over a third of the production target so far -ahead of plan. When integrated with general bought-in solutions, base infrastructure and collaboration benefits, we are routinely adding more than 50mboed gross production per annum.The Paper presents examples of the variety of capability, technology and solution applications that have underpinned this continuing successful value delivery.Key to this success has been:• Establishing an effective, balanced approach to R&D, deployment and value realization;• Developing clear linkage to business needs and functional priorities as a basis for effectively engaging the customer.Areas of continuing challenge include:• Sustaining uptake and usage when faced with issues and barriers arising from technical, business and organizational diversity in the asset portfolio; • Competing or aligning with other business priorities and initiatives, especially in a cost challenged environment.Looking forward, the common challenge all operators face is firmly on making it an industry-wide reality, and to fully embed "intelligent energy" in all that we build and operate.

“…Surface 4D seismic has been used to characterize the distributions of remaining oil through the differences of data surveyed over time (Lumley, 2001). However, because of the long intervals of data acquirements (normally at a few years), the measurement backgrounds are usually changed, wherefore time-lapse data processing is difficult to produce the results with high accuracy, high resolution, and high signal-to-noise ratio (Watts et al, 2006). Permanently installed downhole geophones are expected to be able to indirectly locate the displacement front, but data interpretation is difficult because of the natural insensitivity of elastic waves on fluid components (Gagliardi and Lawton, 2012).…”

Reservoir monitoring using borehole radars to improve oil recovery: Suggestions from 3D electromagnetic and fluid modeling

et al. 2018

The recently developed smart well technology allows for sectionalized production control by means of downhole inflow control valves and monitoring devices. We consider borehole radars as permanently installed downhole sensors to monitor fluid evolution in reservoirs, and it provides the possibility to support a proactive control for smart well production. To investigate the potential of borehole radar on monitoring reservoirs, we establish a 3D numerical model by coupling electromagnetic propagation and multiphase flow modeling in a bottom-water drive reservoir environment. Simulation results indicate that time-lapse downhole radar measurements can capture the evolution of water and oil distributions in the proximity (order of meters) of a production well, and reservoir imaging with an array of downhole radars successfully reconstructs the profile of a flowing water front. With the information of reservoir dynamics, a proactive control procedure with smart well production is conducted. This method observably delays the water breakthrough and extends the water-free recovery period. To assess the potential benefits that borehole radar brings to hydrocarbon recovery, three production strategies are simulated in a thin oil rim reservoir scenario, i.e., a conventional well production, a reactive production, and a combined production supported by borehole radar monitoring. Relative to the reactive strategy, the combined strategy further reduces cumulative water production by 66.89%, 1.75%, and 0.45% whereas it increases cumulative oil production by 4.76%, 0.57%, and 0.31%, in the production periods of 1 year, 5 years, and 10 years, respectively. The quantitative comparisons reflect that the combined production strategy has the capability of accelerating oil production and suppressing water production, especially in the early stage of production. We suggest that borehole radar is a promising reservoir monitoring technology, and it has the potential to improve oil recovery efficiency.
