        DIGITAL LONG SPACING ACOUSTIC TOOL (DDBHC), SJSCC

        SJSCC makes full use of the information contained in the waveform behind the first sonic wave to defect sonic transmission features in the formation. Logs of long spacing (8’-10’-12’) sonic tool provides deeper detection depth, beyond the zone damaged by biz or slight invasion zone. Using the digital signal processing software, the compressive, shear and Stoneley waves, including their amplitude, can be acquired in the way of adequate spacing of sampling.

        DIGITAL HIGH RESOLUTION DIPLOG TOOL, DDQC

        DDQC provides measurements for computing stratigraphical dip and structural dip, both of which indicate potential oil and gas reservoirs. The tool has two side-by-side configured electrodes on each pad that provides good likeness logs enabling the computation and analysis of stratigraphical dips. Highly accurate deviation and azimuth are obtained from a tri-axial accelerometer and three magnetometers. It also provides two orthogonal caliper logs.

        CDC-B REPEATED FORMATION TESTER,CDC

        CDC provides accurate in-situ pressure measurements and takes two fluid samples per trip in an openhole to provide answers to drilling, production, and reservoir engineering and geological questions. Operated by an electrically driven hydraulic system, the tool can be set and retracted as often as necessary to measure pressure in all zones of interest during one trip. Pretest pressure can be observed by the engineering to determine if the packer has sealed properly and if the fluid flow is adequate to obtain a diagnostic sample. If either condition is questionable, the tool can be retracted and moved to a more suitable test depth. At the surface, formation pressures are recorded on film and displayed in both digital and analog form.
