Directional Drilling

A major oil and gas play in south-central Oklahoma targeting Woodford and Springer shale formations. Subcontractors working this basin should expect high-volume drilling and completions activity. It is a key area for securing long-term field service contracts.

The full sequence of a well's existence, from drilling and completion through production and eventual abandonment. For subcontractors, each phase represents distinct scopes of work, crew requirements, and contract opportunities. Understanding the lifecycle helps you anticipate project transitions and position for follow-on work.

A method operators use to value oil and gas reserves by discounting future cash flows at 10% annually. Higher NPV10 signals a healthier client who can fund long-term projects and honour contracts. Subcontractors can use it to gauge whether a prospect client's asset base justifies pursuing work with them.

A network of underwater equipment — including wellheads, manifolds, flowlines, and control systems — installed on the seabed to extract and transport oil or gas to a surface facility, representing a specialised scope of subsea installation, inspection, and maintenance work that subcontractors must hold specific certifications and equipment to perform. For field service companies, contracts in this space typically involve saturation diving support, remotely operated vehicle (ROV) operations, or subsea engineering services under strict offshore safety and quality regimes.

The number of drilling rigs actively operating in a region. Published weekly by Baker Hughes, the rig count is a leading indicator of activity levels in the oil and gas industry.

A state-owned oil producer that controls exploration and production within its country. NOCs often require local content compliance, affecting subcontractor hiring and procurement. Payment cycles and approval chains can be longer than with private operators.

What Is an AFE in Oil and Gas and How Does It Affect Subcontractor Payments?

An AFE (Authorization for Expenditure) controls every dollar spent on an oilfield project. Learn how it affects your billing, change orders, and cash flow as a subcontractor.
