Authorship Supervision Experience

For Orenburgneft, based on analysis and study of oil field data presented within frame of authoership supervision the arrangements on quality improvement for casing string fixing by applying two-stage cementing have been worked out. If required, strength calculations for casing strings are carried out based on actual availability of casing pipes, the use of available types of casing heads and Christmas trees are agreed.

For client Ulyanovskneftegaz the analysis on complication causes linked to no returns of drilling mud while drilling prospect well № 96 of Sulakskoye field is performed. Department experts jointly with drilling contractor developed arrangements for their prevention and efficient elimination. Drilling deadline for next well № 99 was considerably reduced (43 days instead of 55), which made it possible considerable cost reduction for well site construction.

At present day work on well site construction engineering for well №1 P of Nizhnemazinskoye field, well № 12 of Slavkinskoye field and well № 95 of Sulakskoye field.

Construction schedule of prospect well №96 Sulakskaya (without well site construction engineering)

Construction schedule of prospect well №99 Sulakskaya (with well site construction engineering within frame of aurthiship supervision)

For Zarubezhneft, within frame of authoership supervision on well site construction for cyclic steam soaking in Boca de Jaruco oil field, Republic of Cuba, drilling department experts took part in preparation of action plans on elimination of lost-circulation zones while drilling for casing string on wells №№ BJ-2001, BJ-2002 and BJ-2003, in work package development to implement procedures for oil recovery enhancement on wells №№ BJ-3001, BJ-3002, BJ-3003 and others.

When executing offshore project for prospect well LX-01 in west section of block L in Republic of Cuba, drilling department experts took an active part in development of Drilling Program for well construction and for cutting-edge development of arrangements to eliminate geological complication.

During the current year the contract with client Rusvietpetro for authorship supervision on well construction in Central Khoreyverskoye Upheaval oil fields was awarded. The following tasks have been set before drilling department experts:

  • To perform analysis on well stock with a possible structure modification and with completion option to ensure highest production capability on  further well operation;
  • To work out arrangements on quality improvement for casing string fixing in producing zone;
  • To work out efficient for production wells of Central Khoreyverskoye Upheaval oil fields procedures on drilling-in and casing perforation.
