This lecture presents approaches for increasing production from horizontal wells with multistage fracture (HWMSF) completions in conventional reservoirs. HWMSF completions are now regularly being drilled and completed in low-to-mid-permeability oil-bearing conventional reservoirs (k<10 md) where the oilfield is under waterflooding. Although the industry has closed the HWMSF technology gap of drilling and completing these wells, the productivity has been below the expected level. The production is characterized by either an early-time relatively high production rate followed by a steep production decline and water breakthrough or low initial production and even lower late-time production.
What went wrong and what can be done? The lessons learned in unconventional reservoirs are not pertinent to conventional formations. Hence, the
problem was examined from the reservoir standpoint, focusing on achieving adequate pressure support to maximize drainage, revising the waterflood process through drilling patterns,
and evaluating the specific completion techniques. Equally, the question warrants answers on current HWMSF restimulation,
addressing methodology applied to specific completion design, the horizontal wellbore azimuthal orientation within the stress
field, and, finally, the operating condition of the injector and producer wells. The lecture discusses novel designs for refracturing and for future reservoir development, and, at the same
time, is a plea to the drilling, completion, and reservoir engineering teams to integrate their competencies to optimize these complex production systems. |

Schlumberger President for Russia and Central Asia. He has a Masters degree in petroleum engineering, University of Zagreb,
Croatia, and has been based in Moscow, Russia, for the last 15 years. He has more than 27 years of worldwide onshore and offshore exposure and
experience in multiple oilfield service domains. Currently, he is responsible for the assessments and integration process for
complex subsurface projects and for defining the company business model and technological solutions, including new directions in Schlumberger R&E centers in Russia. Kreo Kurt has
published a series of several technical papers for SPE and Russian journals, received the Schlumberger Well Services R&D
Input Award, and holds several patents related to hydraulic fracturing stimulation and IOR/EOR. He is a member of SPE and
EAGE and a member of the Society of Core Analysts. He has been on program committees of international and Russian technical conferences. He served as the Program Director for the
Moscow SPE Section and was awarded the Regional Service Award in 2014. Since 2014, he has been the SPE Moscow Section
Chairperson. He is a fluent speaker of Russian, English, German, Italian, and Croatian. |

| Distinguished Lecturer Program started in 1961 with three lecturers the Distinguished Lecturer Program is funded primarily by the SPE Foundation through member donations and a contribution from Offshore Europe. We also appreciate the companies that allow their professionals to serve as lecturers and the additional support from AIME. More than 450 presentations are offered each year, and each section can receive up to three lectures per year. |
