From Pore to Pipeline: Integrating Exploration and Production Technologies

While the industry experiences the most challenging downturn in more than 30 years, sustainable solutions are more important than ever to ensure that rising demand for oil and gas can be met. For Schlumberger, the way to meet increased demand is to combine technology and new business models and advanced integrated systems that improve efficiency and enable unprecedented levels of collaboration and integration across the full spectrum of E&P technology—from pore to pipeline.

Reservoir Characterisation

The pore to pipeline journey starts with the key technologies used in characterising the subsurface, including seismic surveys, wireline logging, well testing, well testing simulation of well performance, and evaluation of downhole risk and data analysis. The better a reservoir is understood, the better positioned operators and services companies are to optimise its lifetime performance.

One example of improving efficiency with technology comes from Kuwait, where using the Saturn 3D radial probe in an exploration well in an extremely tight cretaceous carbonate reservoir saved an operator 14 days of rig time. Saturn probe technology positions self-sealing ports against the borehole wall to optimally draw reservoir fluids.

Well Construction

Following reservoir characterisation, a well is constructed—this involves creating a secure, pressure-balanced path from the reservoir to the wellhead. In the Middle East, an operator sought to drill an onshore extended-reach well in a challenging high-temperature geological environment from a surface location adjacent to an urban area.

Rigorous pre-job planning helped Schlumberger to design an application-specific drilling system that integrated drillbit design, directional drilling, LWD, drilling fluids, surface logging services, and holecleaning services but also considered subsequent wireline logging and cementing operations. As a result, the operator achieved the longest, high-temperature, extended-reach-drilling (ERD) well despite bottomhole circulating temperatures reaching 315 degF [157 degC].

The most recent addition to the Schlumberger portfolio of technologies used for well construction is the DrillPlan digital well construction planning solution, which is part of a fully integrated well construction offering that transforms planning and execution performance. The DrillPlan solution offers a new way of working that will deliver quicker and better-quality drilling programs through the automation of repetitive tasks and validation of end-to-end workflows to ensure the entire plan is coherent. In West Texas and Canada, oil and gas companies extensively evaluated the DrillPlan solution, customising it to fit their well construction process and found it to be a comprehensive and powerful tool that delivers a well planning programme in days rather than weeks.

Completing the Well

Once the well is drilled and cemented, technologies must be applied to unlock the hydrocarbons from the rock pores and facilitate their flow to the wellbore. These technologies include hydraulic fracturing stimulation treatments and completion technologies to restore or enhance well productivity in all types of formations and reservoir environment.

In Oman, Schlumberger created an integrated “shoot and drop” completions operation that could be deployed in a single trip for a customer to enhance productivity in seven wells. The technologies included a QUANTUM RH retrievable hydraulic-set sealbore production packer and SXAR automatic gun release. QUANTUM RH packer technology absorbs the high shock produced during perforation operations while enabling easy recovery. The customer increased production by an average of 200 m3/d of oil per well and saved a total of $700,000 in associated well costs for all seven wells.

Producing the Field

Once the well has been completed and the hydrocarbons are flowing from the well, infrastructure must be put in place to manage the flow of the production stream as well as prepare the oil and gas for the marketplace. With the acquisition of Cameron in 2016, Schlumberger now offers a range of technology from wellhead to pipeline for use on land and offshore that recovers and stores hydrocarbons, manages water quality, controls and enhances asset performance, maintains well equipment, and monitors produced streams.

Pore to pipeline represents the integration of Schlumberger oil and gas exploration and production technologies into a holistic offering that provides optimal efficiency and recovery rates—from the first geological survey to the delivery of the produced fluids to the end-user.
