2.2 Well Testing Service

2.2.1 Surface Well Testing Service

· Surface well testing equipment along with 15K and 10K pressure rating service and international EXPRO Edgex-II data acquisition system have capabilities for effective evaluation of exploration well and production well. The main services areas were in Iraq, Ukraine and Kazakhstan.
· The surface well testing service can obtain dynamic data of reservoir, such as pressure, temperature and oil & gas rate. And the oil & gas reserves of the production zone can be calculated according to this dynamic data.
· Also the surface well testing can measure many parameter of flow, such as fluid viscosity, composition, gas productivity, oil recovery index and other required data.
· Provide the reliable basis for oil field development plan.

2.2.2 DST service (cased hole and open hole)

Cased-hole drill stem testing: ZPEC has the capabilities of providing 15K and 10K down-hole DST tool service, which apply the annulus pressure to control the down-hole tools on surface. The DST tools can work in multi down-hole conditions like as offshore well, land well, high deviated well, and underbalanced well in Iraq and Kazakhstan.

· Open-hole drill stem testing: Open hole DST usually was applied to obtain required parameters of formation and fluid under dynamic flowing conditions to timely and accurately evaluate the production zone during drilling period. The main services area in Iraq.
· Open-hole drill stem testing can eliminate the mud hydraulic pressure which was always forced on the production zone and connect the formation with decreasing the resistance of flowing by open hole packer operation. Meanwhile the dynamic sampling and pressure can be obtained.
· Open-hole drill stem testing can decrease the pollution time of formation by many kinds of down hole operation. In this way, the formation can be protected and effectively evaluated special for low permeability, low pressure and easy pollution formation.
