2007 - 2008 :
DMI started a new project in 2007 for Green Fields International (GFI) / Salamander Energy in the Gulf of Thailand. DMI provided project management, drilling and completion engineering, drilling and completion fluids design, rig supervision, and logistic personnel for the marginal field development in the Gulf of Thailand. A total of 10 people (including rotational personnel) were assigned to the project that was completed in May 2008. Six wells consisting of five oil producers and one water injection were delivered in 58 days from spud to rig release. The oil producers were the first ever ESP gravel packed completions utilizing a solids free oil base carrying fluid in S.E. Asia.
DMI continued the original Apache China project with the new owner, Roc Oil Bohai Company. The 2007 program was highlighted with a 50% improvement in drilling performance, which was already the highest performance outside of Thailand for offshore development drilling. This was accomplished by using various new technologies and techniques. The 2008 program took on new challenges including installation of a second platform, operations with a new submersible swamp barge, use of splitter wellheads and re-designed unitized wellhead / horizontal tree system, and the major reconstruction of the original platform rig on the first platform (CPOE Rig 70003 Recertification Project). More challenging well construction was performed to the same high standards as previous years while implementing many new ideas.
In 2008 DMI also began preliminary work on a new offshore exploration project in China for Singapore Petroleum Company (SPC). This is the first operated drilling project for SPC. DMI will provide drilling project management, rig supervision, mud engineering, and logistic base setup.
