The productivity of the
Bazhenov formation will be
considered in KhMAD
RussNeft launched a pilot project
for the construction of wells at
Sredne-Shapshinskoye oilfield,
which the company will explore the
Bazhenov shale.
In 2017, the company intends to
drill on the field 16 new wells in
3 well clusters. The productivity
of sediments is directly related
to abnormally high formation
pressure (AHRP), which is caused
by the lack of primary migration
of hydrocarbons in traditional
reservoirs. The presence of
abnormally high pressure zones
improves the properties of the
reservoir, this increase the time
of natural exploitation without the
use of secondary methods. But,
at the same time increases the
threat of complications during
the drilling. For prediction of pore
pressure prediction using various
types of well logging, seismic,
drilling data. Given the presence
of a zone of abnormally high
pressure that is unique to the
Bazhenov deposits, drilling in the
Medium-Shapshinskoye oilfield
use innovative service prediction
of pore pressure prediction.
The new service is based on an
integrated approach: the hardware
is built on the basis of engineering
calculations that helps to minimize
risks during the drilling. Resources
of the Bazhenov formation in
Sredne-Shapshinsky field contain
more than 40 million tons.
Oil from coral reefs
In the framework of the
implementation of the Technology
strategy Gazprom Neft has
developed a program of
introduction of new technologies
for extraction of oil from carbonate
and fractured reservoirs. These
include more than 40% of
recoverable reserves (about 600
million tons of hydrocarbons). At
the fields of Gazprom Neft about
40% of the remaining reserves are
contained in carbonate reservoirs.
The largest assets with such
deposits are the Eastern section
of the Orenburg oil and gas
condensate field, and Chonskoy at
Kuyumbinskoe field in East Siberia,
the project of Badra in Iraq, the
Prirazlomnaye field in the Pechora
sea.
A new program developed by the
Scientific and technical center of
Gazprom Neft and includes 12
technological projects in the field
of exploration, mining, drilling and
production of oil.
In particular, Chonskoy project will
apply technology for intensification
of oil production from a carbonate
reservoir, the pores of which are
partially filled with salt and do
not leak oil. On at Kuyumbinskoe
field is the choice of technology to
acid fracturing and on the Eastern
section of the Orenburg field of
technological solutions aimed at
the search of optimum modes of
operation of the wells.
Reactivate plugged and
abandoned wells
RN-Sakhalinmorneftegaz has
successfully completed the
construction of the energy complex
Katangli on the same field and
started commissioning works.
As reported on March 1, 2017
by Rosneft, modular and energy
complex became the 1st of the
largest in the Sakhalin region.
The total capacity of 12 MW 6
gas turbine units provide, capable
of operating in PNG. In addition,
5 of the boiler can produce 125
t/h process steam. In all, the
complex of over 20 buildings and
structures: transformer station 6/35
kV, the area of power generation,
automatic gas distribution station,
boiler, etc.
With the launch of the energy
complex of the Katangli field is
expected to resume production
at the mothballed wells that will
provide growth in daily production
by more than 30%.
