Until recently almost all the workload of our company was conducted for private oil and gas companies. National gas and oil companies have already survived hard times. Equipment was not updated; rates of drilling and hydrocarbon production were decreased. Access to them was denied.
The changes and reformations are taking place now. Management of national oil and gas companies was headed by new specialists, which have chosen new directions of development. National companies were allowed to Involve private service companies to work. Such an approach will allow to increase the rate of drilling and production significantly.
This is the first well where service of drilling fluid is conducted after the new clean procedure of tender purchases.
The field is largely depleted. The productive horizons are with abnormally low formation pressure. Drilling-in of the pay-zones within the interval of 2950-3900 m will be performed with utilization of the clayless drilling mud Biocar®. It will provide minimal damage of the reservoir and a high penetration rate.
PARAMETERS OF CLAYLESS BIOPOLIMER DRILLING FLUID BIOCAR®:
- Density – 1,12 g/сm3;
- Funnel viscosity (Marsh funnel) – 50-80 s;
- Gel – 6.2/9.5 Pa;
- PV – 12-15 cP;
- YP – 15-18 Pa;
- Filtration loss (API) – 3-5 сm3/30 min;
- KCl – 7%;
- рН – 8-9,5.
A few photos from the well, where you can see the first steps of the modernization of equipment - new shaleshakers and the drilling fluid preparation unit (made in Ukraine).
