        Your guys did an outstanding job for us this past year. Our Mudlogging and Geosteering was greatly improved over our previous years operations, and I know the Company Men were happy with them and their work on location.

          Petroleum Geologist

          Working with Field was really excellent and far exceeded expectations. The mudloggers were extremely prepared for the operation, knowledgeable, and easy to work with. Throughout the job, day or night, I was able to get quick responses and updates on what the mudloggers were seeing with the samples and mud log. The deliverables given to us daily and post job were of high quality as well. The samples were organized, every depth was accounted for and clearly labeled, and plenty of each sample was collected to allow us to get further testing done on our cuttings. Look forward to using Field again in the future.
