WELACO Technical Department

WELACO Technical Department

WAC has a technical department that works tirelessly to keep the computers in the office and on the trucks in good working order in an effort to keep the turn around time of surveys to a minimum

WELACO Fabrication Department

Our fabrication department consists of a complete machine shop with the full capability of constructing down hole logging tools, offshore skid units, portable mast units, and modification of equipment. The complete fabrication of new wireline units and electronic units can be completed by our fabricators. Our in house fabricator can manufacture high quality tools and equipment in a minimal amount of time. It is for this reason that WELACO can sustain a high level of quality while meeting the needs of an active and growing industry.

    Welaco's Machine Shop Offers Construction of:
  • Down hole logging tools
  • Offshore skid units
  • Portable mast units

Features and Benefits

SUBSURFACE

The 1.83 in. size tool string offers the advantage of accessing zones of interest through tubing strings, also in many wellbore geometries the device has been used routinely to evaluate zones through both the tubing and casing strings.

INSTRUMENT INTEGRITY

High speed and stable electronic performance combined with optimized detector design results in accurate log data with statistical uncertainty of the measurement appreciably less than conventional devices.

MiI grade component selection and stringent design criterion result in stable operation of the downhole instruments in hostile environments.

QUALITY ASSURANCE

Since the thrust of this development was that of reservoir monitoring and time lapse logging to detect subtle changes, the stringent calibration and quality assurance procedures are maintained. In addition to API and industry standard compliance, periodic operating characteristic checklist testing is conducted at our technical facility. This ensures consistent log response on every log and therefore a greater degree of confidence in the interpretive aspects of the service.

About Well Analysis Corporation

Our Beginnings

Welaco opened for business in October, 1990 with three logging units. Each unit contained analog equipment. We had one contract, Shell Oil Company. Welaco has seen steady growth since the business began, even though the industry was indolent. We contribute this to the quality of service that Welaco provides;

Welaco is now the largest production logging company on the west coast, with our home office based in Bakersfield, California. Additional offices are located in Los Angeles, California and Fallon, Nevada. We have computerized production logging units, in-house drafting and log reproduction, and a complete machine shop which produces our down-hole electronic tools. An Electronics Engineer is on staff to repair and manufacture electronic boards for tooling. Welaco is committed to a full time R&D department.
