In addition to the intelligence, resourcefulness and experience of ATP’s people, management’s decision to invest significantly in state-of-the-art technologies has helped position ATP as a leader in the industry and has contributed to ATP’s high success rate in converting PUD’s to proved developed reserves. 
ATP has attracted a superior team of experienced industry professionals with strong academic backgrounds.  The ability of these people to understand complex technologies combined with their years of practical offshore oilfield experience enables them to look beyond traditional development methods.  ATP’s people consistently extend existing technology to find the economic answers demanded by these times.

Innovations
ATP employs creative development solutions and utilizes the latest technology to develop its offshore properties.

  • Dual Blowout Preventers for Safety Redundancy
    While ATP's corporate strategy is to focus on low risk, previously drilled development properties as opposed to exploration drilling, ATP was the first in the Gulf of Mexico to utilize a Subsea Isolation Device (SID) in addition to the typical surface-blowout-preventer (BOP) to further reduce risk during drilling operations. Besides using a surface stack, the ATP Titan deepwater floating drilling and production facility incorporates a SID for an additional level of both safety and well control at the seafloor. The SID, which consists of a double ram preventer equipped with two blind/shear rams, a wellhead connector and re-entry hub, is controlled, in the primary mode, by an innovative modular subsea control system. A backup remote-operated-vehicle (ROV) interface provides supplementary control in the event the primary system is disabled.

  • Currently under fabrication for ATP’s U.K. North Sea Cheviot field development is the Octabuoy Dry Tree semi-submersible production platform.  The Octabuoy, a dry-tree completion unit, can accommodate both production facilities and a complete drilling/work-over rig, allows for fabrication and installation flexibility, provides oil storage in the columns and is expected to be more cost effective than other dry-tree floating production units. The unique feature of the Octabuoy is the shape of the columns, which provides more favorable motion characteristics than other floating structures for dry-tree oil and gas production.

  • In 2007, due to lack of nearby accessible infrastructure near ATP’s Telemark Hub project, ATP decided to utilize a self contained floating drilling and production triple-column spar structure.  This is the first hull configuration of this kind. This versatile deepwater operating concept, comprised of three columns linked by pontoons, offers higher variable load capacity and enhanced stability over traditional single-hulled spars.

  • In 2006, with limited infrastructure in the vicinity and an aggressive schedule to first production, ATP elected to convert a semi-submersible rig into a floating production platform to develop its Mississippi Canyon 711 property in the deepwater Gulf of Mexico. The nearest platform for tieback was over 30 miles away, which would have introduced flow assurance problems and cost impediments as well as significantly reducing reserve recovery. The ATP Innovator semisubmersible floating production platform is permanently moored by a 12-point taut-leg polyester/chain mooring system, fixed to the seabed via suction embedded plate anchors. This is the first time a floating production unit has these types of anchors in the Gulf of Mexico; polyester mooring provides lower cost and, we believe, better performance than conventional steel catenary systems. The company installed the facility and began first production within 16 months of project sanction, despite the busy 2005 hurricane season.  ATP later upgraded the facility with additional capacity and refined compression to enable the facility to process third-party production. ATP was recognized by Oil & Gas Investor with the Best Field Rejuvenation 2007 Award.

  • In 2004, ATP won the Offshore Energy Achievement Award for Innovation / Technology for its innovative use of plinths, platform extension legs that sit on the bottom of the ocean floor.  Selected from more than 100 nominations, ATP’s use of plinths at Ship Shoal 358 and Garden Banks 142/186 allowed the Company to realize substantial cost savings by relocating two platforms from water depths of approximately 360’ to over 500’.

  • In 2002, ATP set a new world record for the Longest Subsea Oil Tieback (Hart’s E&P) at its Ladybug wells in Garden Banks Block 409 in the Gulf of Mexico.  About 91,865 feet, or approximately 18 miles, of 6-inch pipe were set in 1,360 feet waters to tie the Ladybug wells to the Garden Banks 189 “A” platform.

  • In 2001, ATP demonstrated the reliability of remote sensing in its hydraulic control systems to the satisfaction of the regulatory agency responsible for design approval and routine inspection.  A new procedure was developed and modeled to optimize and standardize the deployment of ATP’s subsea wells to economically develop smaller fields. ATP is one of the most active operators utilizing subsea technology in the Gulf of Mexico.  ATP owns and operates 24 subsea wells that are producing or under development.
  • During 1999, ATP pushed existing technology to a higher level by developing a subsea well in 500 feet of water with an 11-mile pipeline and an umbilical controlled by direct hydraulics (at the time the longest direct hydraulic system worldwide).  Prevailing wisdom held that direct hydraulics could not be used for distances beyond five to seven miles.  The cost of installing, maintaining and abandoning a fixed structure at this prospect would have been uneconomical without the tieback.  ATP was awarded Best Field Improvement Project 1999 for this innovation by Hart’s Oil and Gas World magazine.
  • ATP has skillfully employed the techniques of extended reach directional and horizontal drilling since 1994.  Directional drilling technology has advanced ATP’s success by exposing more productive formation area to flow, which results in higher initial production rates and reducing water production in high-permeability zones.  Horizontal wells have the benefit of extending an elongated completion in the most prolific section of a reservoir.  For appropriate projects ATP has also employed the utilization of horizontal subsea trees.  A horizontal subsea tree allows for full-bore vertical access to downhole equipment without having to remove the tree, greatly simplifying well bore intervention.  A horizontal subsea tree can reduce rig time, provide better well control, and reduce the risk of well control incidents.

Communication and partnership enhancement
ATP incorporates innovative use of networking and the internet for enhanced communication.  ATP operates 37 platforms, 28 of which are unmanned, using new e-based technology for speed, accuracy, remote monitoring and communication, thus dramatically lowering costs.  ATP’s use of internet technology identifies market opportunities and reduces costs through partner contact.  Secured online information portals and trading hubs are used to monitor pricing and capacity availability for potential savings and efficiency.  Communications with partner contacts streamlines real time nomination and price information and develops crucial alliances.  The Inc./Cisco Growing with Technology Award 2000 recognized ATP’s innovative use of internet and networking technologies.
