Shell has awarded Schlumberger a five-year, multicountry integrated services contract for the drilling of oil and gas exploration wells on a recently commissioned deepwater rig operating in East, West and North Africa. The concept of using a highly mobile drilling rig for exploration in remote deepwater environments is enhanced by the integration of services over a reduced footprint, resulting in overall efficiency gains. In addition, the continuity of people and processes along with the application of lessons learned are key enablers for reducing operational risk and non-productive time.
In the Norwegian sector of the North Sea, a total of 11 Schlumberger oilfield services contracts have been extended over the next five years with BG Norge to cover both the development of the Knarr field as well as other activities on the continental shelf. The contracts include directional drilling, measurements and logging while drilling, mud logging, wireline logging, drilling fluids management, coiled tubing, well testing, perforating, completions and cementing services.
In the UAE, Wireline MicroPilot* single-well in situ enhanced EOR evaluation technology was introduced for Abu Dhabi Company for Onshore Operations (ADCO) in a well to carry out downhole water and formation crude oil injection. MicroPilot technology provided valuable information on the rock properties governing oil and water movement in the reservoir. This information also helped to bridge the gap between the core and reservoir scales, allowing improved reservoir modeling.
Offshore Congo, Schlumberger technologies were deployed for ENI in the drilling and completion of a highly complex well in the Mwafi field. Drilling & Measurements PowerDrive Archer* high build-rate rotary steerable system technology with customized Smith drill bits were used to drill a challenging 3D well profile through the overburden. Well placement in the reservoir was performed in real time using Drilling & Measurements PeriScope* bed boundary mapper, adnVISION* azimuthal density neutron, and SonicScope* multipole sonic while drilling technologies. The well was drilled to total depth more than 20 days ahead of schedule and completed with a three-stage fracturing job using PropGUARD* fiber-based proppant flowback control technology and the Bourbon Herald Well Services stimulation vessel.In Colombia, Well Intervention LIVE* digital slickline technology was deployed for Chevron on an onshore well abandonment campaign. The LIVE service provided both mechanical and real-time cased-hole services in a single unit to recover a well isolating plug, punch multiple tubings with Wireline PowerJet Omega* deep penetrating shaped charges, and run a clean chemical tubing cutter using Testing Services eFire* electronic firing head technology correlated in real time. The operational efficiency provided by this combination of Schlumberger technologies saved Chevron significant logistical costs and reduced total operating time from 27 planned days to 21 days.
